ie 9 ie8 plupload 上传按钮问题 处理

参考： http://stackoverflow.com/questions/21014586/plupload-does-not-seem-to-be-uploading-files-in-ie-9-it-works-in-other-browsers
有可能你是弹出层 里面显示的上传控件，弹出层是隐藏的。ie9 以下对隐藏的 uploader不能很好的渲染，

所以解决方案就是 ，在你做弹出层动作之前，show出弹出层。问题解决。

或者是少加了参数 runtime

For everyone who has same problem as me:

I had the following

HTML

code

<div class="container" style="display:none">
<div>
Logo:
</div>
<div style="clear"></div>

<div id="uploader">
<div id="runtime" class="right">
No runtime was found !
</div>
<div>
<a id="pickfiles" href="#">[Select files]</a>
<a id="uploadfiles" href="#">[Upload files]</a>
</div>
</div>
</div>

The class

container

was
created as dialog

$(function(){

$(".container").dialog({modal:true, width:400});
});

As we know that

DIV

is
initial hidden because of

dispaly:none

(of
course, you can set up

autoOpen:false

as
a new option in dialog object) and remove the style.

In

IE8

(probably
in earlier and later version) the uploader cannot be good instantiated if the

div

is
hidden. (Returns the above error)

In

Chrome

and

Firefox

(I
don't test this issue in

Opera

)
works fine.

So, my advice is to avoid hidden block (even if you wish to create modal dialog).

I removed the

display:none

style
and

dialog

object
from that div and now works very good in

IE8

.

Why? I don't know why in

IE

,
the instance of object is not created at start-up of page, though in

Firefox

and

Chrome

,
the instance was created normally.
