IE9 js图片预览 可设定显示出来的图片大小

//IE当中图片预览
	function dox(obj) {
		obj.select();
		obj.blur();
		var nfile = document.selection.createRange().text;
		document.selection.empty();
		document.getElementById("tp").style.filter = "progid:DXImageTransform.Microsoft.AlphaImageLoader(sizingMethod='scale',src='"+ nfile + "')";
	}
