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);

我通过使用以下代码修复了它:

$("#editor").live('input paste',function(e){
    if(e.target.id == 'editor') {
        $('<textarea></textarea>').attr('id', 'paste').appendTo('#editMode');
        $("#paste").focus();
        setTimeout($(this).paste, 250);
    }
});

现在我只需要存储插入符号的位置并附加到该位置，然后我就全部设置好了……我认为:)

为了跨平台兼容性，它应该处理oninput和onpropertychange事件:

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

将字段的原始值与更改后的值进行比较，然后扣除差值作为粘贴值，如何?这将正确地捕获粘贴的文本，即使字段中存在文本。

http://jsfiddle.net/6b7sK/

function text_diff(first, second) {
    var start = 0;
    while (start < first.length && first[start] == second[start]) {
        ++start;
    }
    var end = 0;
    while (first.length - end > start && first[first.length - end - 1] == second[second.length - end - 1]) {
        ++end;
    }
    end = second.length - end;
    return second.substr(start, end - start);
}
$('textarea').bind('paste', function () {
    var self = $(this);
    var orig = self.val();
    setTimeout(function () {
        var pasted = text_diff(orig, $(self).val());
        console.log(pasted);
    });
});

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
})
