在页面中调用接口:
that.form.template = JSON.stringify(that.form.template)
console.log(that.form.template)
putObj(that.form)
.then((data) => {
if (data.data.code === 0) {
that.$message.success('保存成功')
that.certificateNameShow = false
} else {
that.$message.error(data.data.msg)
}
})
.catch(() => {
})
通过接口访问回显:
console.log(this.tableData.template)
this.tableData.template = JSON.parse(this.tableData.template)
修改时的template打印:
[
{
"type":1,
"content":"<p style=font-size:19px;\"\">@info-studentName@</p>",
"image":"",
"dx":-75,
"dy":-97
}
]
接口回显时打印template:
[
{
"type":1,
"content":"<p style="font-size:19px;">@info-studentName@</p>",
"image":"",
"dx":-75,
"dy":-97
}
]
此时 style后自动添加了双引号 报错Uncaught (in promise) SyntaxError: Expected ',' or '}' after property value in JSON at position 32
style里改成单引号试试,应该就OK了
其实不太明白整个页面是什么样子的,要是只提交数据,dom部分前端处理呢
请参考:
http://events.jianshu.io/p/6ee8aab83859
JSON.stringify 方法用于将 JavaScript 值转换为 JSON 字符串。当转换对象时,所有的键名都会被双引号包围。
如果在转换时包含了HTML标签,需要确保标签内的引号与外面的引号区分开来。在这个例子中,可以在style属性中用单引号代替双引号,或者用转义字符的方式表示双引号,如:
{
"type":1,
"content":"<p style='font-size:19px;'>@info-studentName@</p>",
"image":"",
"dx":-75,
"dy":-97
}
或者
{
"type":1,
"content":"<p style=\"font-size:19px;\">@info-studentName@</p>",
"image":"",
"dx":-75,
"dy":-97
}
应该是后端那边给统一都替换成了双引号,叫后端修改下
是style后面那个等号的问题
前后端交互:前端传递数据是json格式,非常详细
如有帮助,望采纳
