js获取全屏,复制粘贴功能

//复制功能
var clip = null;

		//针对ie6
		$('.copyit').live("click",function(){
		var code=$(this).parent("p").siblings(".runcode").find("textarea").text();
		window.clipboardData.setData("Text",code);
	   })
	   return;
	}
	ZeroClipboard.setMoviePath("http://www.phpvar.com/phpvar.com/wp-content/uploads/js/ZeroClipboard/ZeroClipboard.swf");//如果ZeroClipboard.js, ZeroClipboard.swf放在同一目录下,可省略这句;
	clip = new ZeroClipboard.Client();
	$('.copyit').live("mouseover", function() {
	  var code=$(this).parent("p").siblings(".runcode").find("textarea").text();
	  clip.setText(code);
	  if (clip.div) {//已创建过包含flash的父层div,则鼠标hover时重新定位flash层的位置
		  //clip.receiveEvent('mouseout', null);
		  clip.reposition(this);
	  }else{
		clip.glue(this)};
