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

它会工作得很好。

 $('').bind('input propertychange', function() {....});                      

这将为鼠标粘贴事件工作。

这段代码为我工作，要么从右击粘贴或直接复制粘贴

   $('.textbox').on('paste input propertychange', function (e) {
        $(this).val( $(this).val().replace(/[^0-9.]/g, '') );
    })

当我粘贴第1节:劳动力成本时，它在文本框中变成1。

为了只允许浮动值，我使用这段代码

 //only decimal
    $('.textbox').keypress(function(e) {
        if(e.which == 46 && $(this).val().indexOf('.') != -1) {
            e.preventDefault();
        } 
       if (e.which == 8 || e.which == 46) {
            return true;
       } else if ( e.which < 48 || e.which > 57) {
            e.preventDefault();
      }
    });

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);

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');
}

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
})
