没有从使用JQuery和Javascript的文件输入HTML控件获取[Object File] [英] Not getting [Object File] from a File Input HTML Control using JQuery and Javascript
问题描述
我有一个文件输入控件和按钮如下： -
< input type =filename =Resumeid =upload>< / input>
< input type =buttonid =btnSavevalue =Saveonclick =sample（）>< / input>
另外一个叫做 sample（）
< script type =text / javascript>
函数sample（）{
var file = $（'＃upload'）[0] .files [0];
alert（file）;
}
< / script>
通过点击 btnsave
$ p code $不会返回 [object File] ，尽管在文件输入控制文件存在。
注意：我使用 IE 11 并加载了Jquery库。
您可能遇到以下问题：导致IE模拟旧版本的本地Intranet 区域。尝试在< head>内添加这行作为第一个条目标记：
< meta http-equiv =X-UA-Compatiblecontent =IE = edge/>

I have a file input control and button as below:-
<input type="file" name="Resume" id="upload"></input>
<input type="button" id="btnSave" value="Save" onclick="sample()"></input>
Also a function called as sample()
<script type="text/javascript">
function sample(){
var file =$('#upload')[0].files[0];
alert(file);
}
</script>
The above function is called on a click of button btnsave.
Issue:Does not return a alert with [object File], inspite of file exist in file input control.
Note: I am using I.E 11 and also loaded Jquery library.
You might be experiencing an issue in which the site you are working on is listed in your Local Intranet zone which causes IE to emulate an older version. Try adding this line as the very first entry within your <head> tag:
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
