jquery中扩展粘贴(past)事件

摘自：http://www.mattbenton.net/2012/01/jquery-plugin-paste-events/

$.fn.pasteEvents = function( delay ) {

    if (delay == undefined) delay = 20;

    return $(this).each(function() {

        var $el = $(this);

        $el.on("paste", function() {

            $el.trigger("prepaste");

            setTimeout(function() { $el.trigger("postpaste"); }, delay);

        });

    });

};

 

使用方法：

$("#some-element").on("postpaste", function() { 
    // do something
}).pasteEvents();
