vue2可以滑块拖动校验自己写不使用插件,可以自定义两张图片,滑块和滑块背景图,可以拖动验证
引用chatgpt内容作答:
下面是一个简单的 Vue 2 代码示例,演示了如何创建一个滑块拖动验证功能,使用自定义的滑块和背景图。
首先,确保你已经安装了 Vue 2,并且在项目中创建了一个 Vue 实例。然后可以按照以下方式编写代码:
在你的 Vue 组件中,创建一个滑块验证区域。
<template>
<div class="slider-verification">
<div class="slider-background" :style="{ backgroundImage: 'url(' + backgroundImage + ')' }">
<div class="slider" :style="{ left: sliderPosition + 'px' }" @mousedown="startDrag" @mousemove="handleDrag" @mouseup="endDrag">
<img class="slider-icon" :src="sliderImage" alt="Slider">
</div>
</div>
<div v-if="isVerified" class="success-message">验证成功!</div>
</div>
</template>
<script>
export default {
data() {
return {
sliderPosition: 0,
isDragging: false,
isVerified: false,
backgroundImage: 'url(path_to_background_image.jpg)',
sliderImage: 'path_to_slider_image.png',
verificationThreshold: 80, // Adjust this threshold according to your needs
};
},
methods: {
startDrag(event) {
this.isDragging = true;
const offsetX = event.clientX - this.$refs.slider.getBoundingClientRect().left;
this.sliderPosition = offsetX;
},
handleDrag(event) {
if (this.isDragging) {
const offsetX = event.clientX - this.$refs.slider.getBoundingClientRect().left;
this.sliderPosition = Math.max(0, Math.min(offsetX, this.$refs.background.offsetWidth));
}
},
endDrag() {
if (this.isDragging) {
this.isDragging = false;
if (this.sliderPosition >= this.verificationThreshold) {
this.isVerified = true;
} else {
this.sliderPosition = 0;
}
}
},
},
};
</script>
<style>
.slider-verification {
position: relative;
width: 300px;
height: 150px;
}
.slider-background {
position: relative;
width: 100%;
height: 100%;
background-size: cover;
background-repeat: no-repeat;
}
.slider {
position: absolute;
top: 0;
left: 0;
height: 100%;
cursor: pointer;
}
.slider-icon {
position: absolute;
top: 50%;
left: -15px;
transform: translate(0, -50%);
}
.success-message {
margin-top: 10px;
text-align: center;
color: green;
}
</style>
在这个示例中,我们创建了一个滑块验证区域,其中包含了滑块和背景图。滑块可以通过鼠标拖动,当滑块位置超过验证阈值时,会显示验证成功的消息。你需要根据你的实际需求,调整背景图片路径、滑块图片路径以及验证阈值。
这只是一个简单的示例,实际应用中可能需要更多的功能和优化。希望这个示例能帮助你开始创建滑块拖动验证功能!
百度找一下官网文档,试试这三个插件:VeeValidate,Vuelidate,vue-formulate
首先,需要在Vue项目中引入两张自定义图片,并添加样式。
具体实现步骤如下:
在组件中定义需要用到的data数据,包括:滑块位置、滑块宽度、滑块背景图的地址、滑块的地址等信息。
在HTML模板中,使用<div>
标签包裹两张图片,为其设置样式和绑定事件。
实现滑动验证功能,通过监听鼠标移动的事件,动态计算出滑块当前的位置,并根据位置的变化,设置相关的样式。
添加提交按钮,当滑块验证成功后,才能够提交表单。
下面是完整代码示例:
<template>
<div class="verify-container">
<div class="verify-img-wrap">
<img :src="bgImg" alt="" class="verify-img-bg">
<img :src="sliderImg" alt="" class="verify-img-slider" @mousedown="onMouseDown">
</div>
<button :disabled="!isVerified" @click="submitForm">提交</button>
</div>
</template>
<script>
export default {
data() {
return {
sliderPos: 0,
sliderWidth: 40,
bgImg: 'path/to/bgImg',
sliderImg: 'path/to/sliderImg',
startX: 0,
isMousedown: false,
isVerified: false,
};
},
methods: {
onMouseDown(event) {
this.startX = event.clientX;
this.isMousedown = true;
this.sliderWidth = 40;
this.sliderPos = 0;
},
onMouseMove(event) {
if (!this.isMousedown) return;
const offset = event.clientX - this.startX;
const maxOffset = 220;
if (offset >= maxOffset) {
this.sliderPos = maxOffset;
this.sliderWidth = 0;
this.isVerified = true;
this.isMousedown = false;
} else {
this.sliderPos = offset;
this.sliderWidth = 40 - offset / 5;
}
},
onMouseUp() {
if (!this.isMousedown) return;
this.isMousedown = false;
this.sliderPos = 0;
this.sliderWidth = 40;
},
submitForm() {
if (this.isVerified) {
console.log('表单提交成功');
} else {
console.log('请先进行验证');
}
},
},
mounted() {
document.addEventListener('mousemove', this.onMouseMove);
document.addEventListener('mouseup', this.onMouseUp);
},
destroyed() {
document.removeEventListener('mousemove', this.onMouseMove);
document.removeEventListener('mouseup', this.onMouseUp);
},
};
</script>
<style scoped>
.verify-container {
position: relative;

height: 140px;
}
.verify-img-wrap {
position: absolute;

}
.verify-img-slider:hover {

display: flex;
justify-content: center;

}
button:disabled {

}
</style>
上述代码中,通过监听鼠标的mousedown、mousemove、mouseup事件,动态计算滑块的位置和宽度,并根据是否验证成功来禁用提交按钮。

下面是一个使用 Vue.js 2 实现滑块校验的示例:
首先,你需要定义一个滑块组件,其中包含滑块和滑块背景图。在模板中,你可以使用 @mousedown
、@mousemove
和 @mouseup
监听滑块的鼠标事件,从而实现滑块的拖动。在 data
中,你可以定义一个变量 sliderPosition
来记录滑块的位置。然后,你可以在滑块拖动结束时触发一个校验方法,根据滑块的位置进行校验。
<template>
<div class="slider-container">
<div class="slider-background"></div>
<div class="slider" :style="{ left: sliderPosition + 'px' }" @mousedown="startDrag" @mousemove="drag" @mouseup="endDrag"></div>
</div>
</template>
<script>
export default {
data() {
return {
sliderPosition: 0,
isDragging: false
}
},
methods: {
startDrag(event) {
this.isDragging = true;
},
drag(event) {
if (this.isDragging) {
const container = event.target.parentNode;
const containerRect = container.getBoundingClientRect();
const position = event.clientX - containerRect.left;
// 校验滑块位置是否超出背景图边界
if (position >= 0 && position <= containerRect.width) {
this.sliderPosition = position;
}
}
},
endDrag(event) {
if (this.isDragging) {
this.isDragging = false;
this.validateSlider();
}
},
validateSlider() {
// 根据滑块位置进行校验
// ...
}
}
}
</script>
<style>
.slider-container {
position: relative;
width: 200px;
height: 20px;
background-color: #f0f0f0;
border-radius: 10px;
overflow: hidden;
}
.slider-background {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-image: url('path/to/slider-background-image.png');
background-repeat: no-repeat;
background-position: center;
}
.slider {
position: absolute;
top: 0;
left: 0;
width: 30px;
height: 100%;
background-color: #007bff;
cursor: pointer;
}
</style>
代码说明:使用 @mousedown
、@mousemove
和 @mouseup
监听滑块的鼠标事件,并在 drag
方法中根据鼠标位置计算滑块的位置,然后根据条件判断将滑块位置更新为当前位置。在 endDrag
方法中,我们结束拖动并触发校验方法。你可以在 validateSlider
方法中根据滑块的位置进行校验操作。
这不很简单么,你弄个模态框,背景图和滑块分别用两个div。检测滑块位置是否到了正确的区间
<template>
<div class="slider-container">
<div
class="slider-background"
:style="{ backgroundImage: 'url(' + backgroundImage + ')' }"
>
<div
class="slider"
:style="{ left: sliderPosition + 'px', backgroundImage: 'url(' + sliderImage + ')' }"
@mousedown="startDrag"
@mousemove="drag"
@mouseup="endDrag"
></div>
</div>
</div>
</template>
<script>
export default {
data() {
return {
sliderPosition: 0,
isDragging: false,
sliderImage: 'path/to/slider-image.png',
backgroundImage: 'path/to/background-image.png'
};
},
methods: {
startDrag(event) {
this.isDragging = true;
this.drag(event);
},
drag(event) {
if (this.isDragging) {
const containerRect = this.$el.getBoundingClientRect();
const newPosition = event.clientX - containerRect.left;
if (newPosition >= 0 && newPosition <= containerRect.width) {
this.sliderPosition = newPosition;
}
}
},
endDrag() {
this.isDragging = false;
// 在这里可以添加验证逻辑,根据滑块位置进行校验
// 示例:if (this.sliderPosition >= VALID_POSITION) { 验证通过 }
}
}
};
</script>
<style>
.slider-container {
width: 300px;
height: 150px;
position: relative;
}
.slider-background {
width: 100%;
height: 100%;
background-size: cover;
}
.slider {
width: 50px;
height: 50px;
position: absolute;
top: 50%;
transform: translateY(-50%);
cursor: pointer;
background-size: cover;
}
</style>
首先,您需要准备两张图片,一张是滑块的图片,另一张是滑块背景的图片。您可以将这些图片放置在项目的适当位置,并在组件中引用它们。
接下来,您可以使用Vue 2的模板创建一个简单的滑块拖动验证组件。以下是一个示例:
<template>
<div class="slider-container">
<div class="slider-background" :style="{ backgroundImage: `url(${backgroundImageUrl})` }"></div>
<div class="slider" :style="{ backgroundImage: `url(${sliderImageUrl})`, left: `${sliderPosition}px` }"></div>
</div>
</template>
<script>
export default {
data() {
return {
sliderPosition: 0,
minPosition: 0,
maxPosition: 0,
};
},
props: {
minValue: {
type: Number,
default: 0,
},
maxValue: {
type: Number,
default: 100,
},
value: {
type: Number,
default: 0,
},
backgroundImageUrl: {
type: String,
default: '',
},
sliderImageUrl: {
type: String,
default: '',
},
},
watch: {
value(newValue) {
this.sliderPosition = newValue;
},
},
};
</script>
<style scoped>
.slider-container {
position: relative;
width: 100%;
height: 100%;
}
.slider-background {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-size: cover;
}
.slider {
position: absolute;
top: 50%;
left: ${this.sliderPosition}px; /* 使用计算属性 */
width: 50px; /* 根据需要调整滑块大小 */
height: 50px; /* 根据需要调整滑块大小 */
background-size: cover;
}
</style>

};
},
computed: {
backgroundStyle() {
return `background-image: url('path/to/background-image.jpg');`;
},
sliderStyle() {
return `background-image: url('path/to/slider-image.png'); left: ${this.offsetX}px;`;
},
},
methods: {
onMouseDown(event) {
event.preventDefault();
this.isDragging = true;
this.startX = event.clientX;
},
onMouseMove(event) {
if (this.isDragging) {
const moveX = event.clientX - this.startX;
this.offsetX = Math.max(0, Math.min(moveX, 200)); // 设置滑块最大可拖动距离为 200px
}
},
onMouseUp(event) {
if (this.isDragging) {
this.isDragging = false;
if (this.offsetX >= 200) {
// 拖动校验成功,触发相应操作
// 在这里可以添加你的逻辑代码
console.log("Verification passed!");
} else {
// 校验失败时,重置滑块位置
this.offsetX = 0;
}
}
},
},
mounted() {
document.addEventListener("mousemove", this.onMouseMove);
document.addEventListener("mouseup", this.onMouseUp);
},
beforeDestroy() {
document.removeEventListener("mousemove", this.onMouseMove);
document.removeEventListener("mouseup", this.onMouseUp);
},
};
</script>
<style scoped>
.slider-verification {
position: relative;
width: 300px; /* 设置组件容器宽度 */
height: 80px; /* 设置组件容器高度 */
overflow: hidden;
}
.background {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-repeat: no-repeat;
background-size: contain;
}
.slider {
position: absolute;
top: 0;
width: 80px; /* 设置滑块宽度 */
height: 80px; /* 设置滑块高度 */
background-repeat: no-repeat;
background-size: contain;
cursor: pointer;
user-select: none;
pointer-events: none;
}
</style>
SliderVerification
引入到你的页面中,并使用它:<template>
<div>
<h1>滑块校验示例</h1>
<SliderVerification></SliderVerification>
</div>
</template>
<script>
import SliderVerification from "./components/SliderVerification.vue";
export default {
components: {
SliderVerification,
},
};
</script>
在上述示例中,通过监听鼠标事件实现了滑块的拖动验证。当滑块的拖动距离达到一定的阈值(在示例中设置为 200px)时,即可认为验证成功,你可以在 onMouseUp
方法中对验证通过时的逻辑进行处理。
请确保将 path/to/background-image.jpg
和 path/to/slider-image.png
更换为你自己的图片路径。另外,你可以根据需要调整组件的宽度、高度和样式。

首先,我们可以创建一个 Vue 组件来实现滑块校验功能。
<template>
<div>
<div
class="slider-background"
:style="{ backgroundImage: `url(${backgroundImage})` }"
@mousedown="onMouseDown"
>
<div
class="slider"
:style="{ left: sliderPosition + 'px', backgroundImage: `url(${sliderImage})` }"
v-show="!isSliding"
></div>
<div
class="slider sliding"
:style="{ left: sliderPosition + 'px', backgroundImage: `url(${sliderImage})` }"
v-show="isSliding"
></div>
</div>
</div>
</template>
<script>
export default {
data() {
return {
sliderPosition: 0,
isSliding: false,
backgroundImage: './path/to/background-image.jpg',
sliderImage: './path/to/slider-image.jpg'
};
},
methods: {
onMouseDown(event) {
this.isSliding = true;
document.addEventListener('mousemove', this.onMouseMove);
document.addEventListener('mouseup', this.onMouseUp);
},
onMouseMove(event) {
// 计算滑块位置
// 可以通过 event.clientX 来获取鼠标当前的横坐标
// 根据具体情况计算滑块位置的算法需要根据实际需求自定义
this.sliderPosition = event.clientX - event.target.getBoundingClientRect().left;
},
onMouseUp(event) {
document.removeEventListener('mousemove', this.onMouseMove);
document.removeEventListener('mouseup', this.onMouseUp);
this.isSliding = false;
// 验证滑块位置是否正确
// 根据具体情况编写滑块校验的逻辑
if (this.sliderPosition >= /* 校验条件 */) {
// 滑块校验通过
// 执行校验通过后的操作,比如发送请求、跳转页面等
} else {
// 校验失败
// 执行校验失败后的操作,比如显示错误提示等
}
}
}
};
</script>
.slider-background {
position: relative;
width: 300px;
height: 50px;
background-size: cover;
background-repeat: no-repeat;
}
.slider {
position: absolute;
top: 0;
width: 100px;
height: 50px;
background-size: cover;
background-repeat: no-repeat;
}
.slider.sliding {
cursor: grabbing;
}
以上代码实现了一个简单的滑块校验功能,可以根据具体需求进行定制。其中,滑块的位置和校验条件可以根据实际情况自定义。如果不清楚如何实现滑块的位置计算和校验逻辑,可以进一步提供详细需求和具体要求,我将尽力提供更准确的解决方案。

我理解的是从左边拖动到右边的滑块吧

在Vue 2中实现滑块拖动校验并自定义滑块和滑块背景图可以通过以下步骤来实现:
1.创建Vue组件:
2.实现滑块拖动:
下面是一个简化的示例代码,供你参考:
<template>
<div class="slider-container">
<div class="slider-background">
<!-- 滑块背景图 -->
<img src="background-image.jpg" alt="Background" />
</div>
<div
class="slider"
:style="{ left: sliderPosition + 'px' }"
@mousedown="startDragging"
@mousemove="dragging"
@mouseup="endDragging"
>
<!-- 滑块图像 -->
<img src="slider-image.png" alt="Slider" />
</div>
</div>
</template>
<script>
export default {
data() {
return {
isDragging: false,
startX: 0,
sliderPosition: 0,
};
},
methods: {
startDragging(event) {
this.isDragging = true;
this.startX = event.clientX - this.sliderPosition;
},
dragging(event) {
if (this.isDragging) {
const offsetX = event.clientX - this.startX;
this.sliderPosition = Math.min(
Math.max(0, offsetX),
/* 设置滑块背景图的宽度 - 滑块图像的宽度 */
);
}
},
endDragging() {
this.isDragging = false;
// 在这里根据滑块位置判断是否通过校验
if (this.sliderPosition >= /* 校验的阈值 */) {
// 通过校验
} else {
// 校验失败,重置滑块位置
this.sliderPosition = 0;
}
},
},
};
</script>
<style scoped>
/* 样式可以根据需求自行调整 */
.slider-container {
position: relative;
width: /* 宽度 */;
height: /* 高度 */;
}
.slider-background {
/* 滑块背景图的样式 */
}
.slider {
position: absolute;
top: 0;
transition: left 0.3s ease;
cursor: pointer;
/* 滑块图像的样式 */
}
</style>
在这个示例中,你需要替换 background-image.jpg 和 slider-image.png 为你自己的图片路径。另外,你还需要根据实际情况设置滑块的校验阈值和滑块背景图的宽度。
