使用JS如何获取剪贴板内容

网上搜寻了很多，在IE中可以使用window.clipboardData对象来设置和获取剪贴板内容，目前没有标准的统一的访问接口。
看了网上说使用Zero Clipboard插件来实现，但是没有获取的具体示例代码，只有设置的示例代码。也不知道使用Zero Clipboard到底是否可以获取剪贴板内容。

具体使用JS该如何获取剪贴板内容呢？有没有使用Zero Clipboard来获取剪贴板内容的示例代码呢？

如果是ie浏览器，并且用户允许剪贴板交互，可以用 window.clipboardData.getData("Text");
别的浏览器，可以借助键盘模拟ctrl+v到表单，然后读取，获得内容。

剪切板的值在粘贴之后可以获取，对象绑定粘贴事件：

    $("#id").on('paste', function(e) {
        var pastedText = undefined;
        if (window.clipboardData && window.clipboardData.getData) { // IE
            pastedText = window.clipboardData.getData('Text');
        } else {
            pastedText = e.originalEvent.clipboardData.getData('Text');//e.clipboardData.getData('text/plain');
        }
        alert(pastedText);
  });

这样应该可以 我在IE, Edge, Chrome 上测试了没问题 希望对你有帮助

HTML

 <div id='div' contenteditable='true'>Paste</div>

JS

 var editableDiv = document.getElementById('editableDiv');

function handlepaste (e) {
    var types, pastedData, savedContent;

    // Browsers that support the 'text/html' type in the Clipboard API (Chrome, Firefox 22+)
    if (e && e.clipboardData && e.clipboardData.types && e.clipboardData.getData) {

        // Check for 'text/html' in types list. See abligh's answer below for deatils on
        // why the DOMStringList bit is needed. We cannot fall back to 'text/plain' as
        // Safari/Edge don't advertise HTML data even if it is available
        types = e.clipboardData.types;
        if (((types instanceof DOMStringList) && types.contains("text/html")) || (types.indexOf && types.indexOf('text/html') !== -1)) {

            // Extract data and pass it to callback
            pastedData = e.clipboardData.getData('text/html');
            processPaste(editableDiv, pastedData);

            // Stop the data from actually being pasted
            e.stopPropagation();
            e.preventDefault();
            return false;
        }
    }

    // Everything else: Move existing element contents to a DocumentFragment for safekeeping
    savedContent = document.createDocumentFragment();
    while(editableDiv.childNodes.length > 0) {
        savedContent.appendChild(editableDiv.childNodes[0]);
    }

    // Then wait for browser to paste content into it and cleanup
    waitForPastedData(editableDiv, savedContent);
    return true;
}

function waitForPastedData (elem, savedContent) {

    // If data has been processes by browser, process it
    if (elem.childNodes && elem.childNodes.length > 0) {

        // Retrieve pasted content via innerHTML
        // (Alternatively loop through elem.childNodes or elem.getElementsByTagName here)
        var pastedData = elem.innerHTML;

        // Restore saved content
        elem.innerHTML = "";
        elem.appendChild(savedContent);

        // Call callback
        processPaste(elem, pastedData);
    }

    // Else wait 20ms and try again
    else {
        setTimeout(function () {
            waitForPastedData(elem, savedContent)
        }, 20);
    }
}

function processPaste (elem, pastedData) {
    // Do whatever with gathered data;
    alert(pastedData);
    elem.focus();
}

// Modern browsers. Note: 3rd argument is required for Firefox <= 6
if (editableDiv.addEventListener) {
    editableDiv.addEventListener('paste', handlepaste, false);
}
// IE <= 8
else {
    editableDiv.attachEvent('onpaste', handlepaste);
}

$("#id").on('paste', function(e) {
var pastedText = undefined;
if (window.clipboardData && window.clipboardData.getData) { // IE
pastedText = window.clipboardData.getData('Text');
} else {
pastedText = e.originalEvent.clipboardData.getData('Text');//e.clipboardData.getData('text/plain');
}
alert(pastedText);
});
