监听粘贴事件并设置一个keyup事件监听器。在keyup上，捕获值并删除keyup事件监听器。

$('.inputTextArea').bind('paste', function (e){
    $(e.target).keyup(getInput);
});
function getInput(e){
    var inputText = $(e.target).val();
    $(e.target).unbind('keyup');
}

该方法使用jqueries contents().unwrap()。

First, detect the paste event Add a unique class to the tags that are already in the element into which we are pasting. After a given timeout scan through all the contents unwrapping tags that don't have the class that you set earlier. Note: This method does not remove self closing tags like See an example below. //find all children .find('*') and add the class .within .addClass("within") to all tags $('#answer_text').find('*').each(function () { $(this).addClass("within"); }); setTimeout(function() { $('#answer_text').find('*').each(function () { //if the current child does not have the specified class unwrap its contents $(this).not(".within").contents().unwrap(); }); }, 0);

嗯…我认为你可以使用e.clipboardData来捕捉被粘贴的数据。如果不成功，看看这里。

$(this).live("paste", function(e) {
    alert(e.clipboardData); // [object Clipboard]
});

请看这个例子:http://www.p2e.dk/diverse/detectPaste.htm

它本质上用oninput事件跟踪每个更改，然后通过字符串比较检查它是否是粘贴。哦，在IE中有一个onpaste事件。所以:

$ (something).bind ("input paste", function (e) {
    // check for paste as in example above and
    // do something
})

$("#textboxid").on('input propertychange', function () {
    //perform operation
        });

它会工作得很好。
