javascript火狐(firefox)不显示本地图片问题解决

<img id="img1" src=""/> <script> function fileChange(obj) { var url = obj.value url = "file:///" + url.replace("\\","/"); alert(url); document.getElementById("img1").src= url; } </script> <input type="file" onchange="fileChange(this);" />

关键是：url = "file:///" + url.replace("\\","/");
