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（"\","/"）;
