添加依赖
太多忘记哪个了。。。添加就完事儿了
$("#file").change(function(){
var objUrl =getObjectURL(this.files[0]);
console.log("objUrl = "+objUrl);
});
function getObjectURL(file)
{
var url =null ;
if (window.createObjectURL!=undefined)
{// basic
url =window.createObjectURL(file);
}
else if (window.URL!=undefined)
{
// mozilla(firefox)
url =window.URL.createObjectURL(file);
}
else if (window.webkitURL!=undefined) {
// webkit or chrome
url =window.webkitURL.createObjectURL(file);
}
return url;
