js完美兼容浏览器的复制功能
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，文件传送门 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) {

}
};

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;

}

},
getHTML: function(width, height) { // return HTML for movie
var html = ''; var flashvars = 'id=' + this.id +
