1，js结合swf的复制功能，完美兼容火狐，谷歌，360，ie8，使用示例：（ps：引入copy.swf比较重要，文件 解压密码：http://www.bieanju.com/，为了防止360删除文件请解压后去除后缀的1）
function copyText(){ var clip = new ZeroClipboard.Client(); clip.setHandCursor(true); //var text= document.getElementById('tgurl').value; var text= $('input[name="tgurl"]').val(); clip.setText(text); clip.glue("copyurl"); clip.addEventListener( "complete", function(){ alert("复制成功！"); }); }
2,下面是copy.js的源码：
var ZeroClipboard = { version: "1.0.7", clients: {}, // registered upload clients on page, indexed by id moviePath: './js/copy.swf', // URL to movie nextId: 1, // ID of next movie $: function(thingy) { // simple DOM lookup utility function if (typeof(thingy) == 'string') thingy = document.getElementById(thingy); if (!thingy.addClass) { // extend element with a few useful methods thingy.hide = function() { this.style.display = 'none'; }; thingy.show = function() { this.style.display = ''; }; thingy.addClass = function(name) { this.removeClass(name); this.className += ' ' + name; }; thingy.removeClass = function(name) { var classes = this.className.split(/\s+/); var idx = -1; for (var k = 0; k < classes.length; k++) { if (classes[k] == name) { idx = k; k = classes.length; } } if (idx > -1) { classes.splice( idx, 1 ); this.className = classes.join(' '); } return this; }; thingy.hasClass = function(name) { return !!this.className.match( new RegExp("\\s*" + name + "\\s*") ); }; } return thingy; }, setMoviePath: function(path) { // set path to ZeroClipboard.swf this.moviePath = path; }, dispatch: function(id, eventName, args) { // receive event from flash movie, send to client var client = this.clients[id]; if (client) { client.receiveEvent(eventName, args); } }, register: function(id, client) { // register new client to receive events this.clients[id] = client; }, getDOMObjectPosition: function(obj, stopObj) { // get absolute coordinates for dom element var info = { left: 0, top: 0, width: obj.width ? obj.width : obj.offsetWidth, height: obj.height ? obj.height : obj.offsetHeight }; while (obj && (obj != stopObj)) { info.left += obj.offsetLeft; info.top += obj.offsetTop; obj = obj.offsetParent; } return info; }, Client: function(elem) { // constructor for new simple upload client this.handlers = {}; // unique ID this.id = ZeroClipboard.nextId++; this.movieId = 'ZeroClipboardMovie_' + this.id; // register client with singleton to receive flash events ZeroClipboard.register(this.id, this); // create movie if (elem) this.glue(elem); }};ZeroClipboard.Client.prototype = { id: 0, // unique ID for us ready: false, // whether movie is ready to receive events or not movie: null, // reference to movie object clipText: '', // text to copy to clipboard handCursorEnabled: true, // whether to show hand cursor, or default pointer cursor cssEffects: true, // enable CSS mouse effects on dom container handlers: null, // user event handlers glue: function(elem, appendElem, stylesToAdd) { // glue to DOM element // elem can be ID or actual DOM element object this.domElement = ZeroClipboard.$(elem); // float just above object, or zIndex 99 if dom element isn't set var zIndex = 99; if (this.domElement.style.zIndex) { zIndex = parseInt(this.domElement.style.zIndex, 10) + 1; } if (typeof(appendElem) == 'string') { appendElem = ZeroClipboard.$(appendElem); } else if (typeof(appendElem) == 'undefined') { appendElem = document.getElementsByTagName('body')[0]; } // find X/Y position of domElement var box = ZeroClipboard.getDOMObjectPosition(this.domElement, appendElem); // create floating DIV above element this.div = document.createElement('div'); var style = this.div.style; style.position = 'absolute'; style.left = '' + box.left + 'px'; style.top = '' + box.top + 'px'; style.width = '' + box.width + 'px'; style.height = '' + box.height + 'px'; style.zIndex = zIndex; if (typeof(stylesToAdd) == 'object') { for (addedStyle in stylesToAdd) { style[addedStyle] = stylesToAdd[addedStyle]; } } // style.backgroundColor = '#f00'; // debug appendElem.appendChild(this.div); this.div.innerHTML = this.getHTML( box.width, box.height ); }, getHTML: function(width, height) { // return HTML for movie var html = ''; var flashvars = 'id=' + this.id + '&width=' + width + '&height=' + height; if (navigator.userAgent.match(/MSIE/)) { // IE gets an OBJECT tag var protocol = location.href.match(/^https/i) ?
