点击提交清除文件字段，而不是提交表单（IE9） [英] Clicking submit clears file field instead of submitting the form (IE9)

问题描述

有时当用户试图提交表单时，文件上传字段 image 只是清除，没有任何反应。我似乎没有提交表格。

然后，一切正常工作的一天。错误发生在随机的天/时间。

首先，我认为这是用户计算机的问题，但这发生在客户有两台不同的计算机上。其中一台电脑有Windows 7 professional& Internet Explorer 9.我没有在另一个设置。

我曾尝试使用Google Chrome，Firefox 6.0.2，Internet Explorer 9,8（浏览器兼容模式），7（浏览器兼容模式）在Windows 7家庭没有任何问题在我的电脑上。

这里是形式：

 < form action =/ user / imagemethod =postaccept-charset =utf-8class =form_defaultenctype =多部分/格式数据> 
< fieldset> 
< ol> 
< li> 
< button type =submitname =savevalue =submitclass =button> Save< / button> 
< / li> 
< li> 
< label for =image>个人资料图片< / label>< input type =fileid =imagename =image/> 
< / li> 
< li> 
< button type =submitname =savevalue =submitclass =button> Save< / button> 
< / li> 
< / ol> 
< / fieldset> 
< / form> 
  

解决方案

应该只有1 提交按钮每个表格。
因此，保存1保存按钮为 type =submit，将另一个保存为 type =button

I got a weird error I hope you guys can help with.

Sometimes when the user tries to submit a form the file upload field image just clears and nothing happens. I doesn't seems like the form get submitted at all.

Then the day after everything works fine. The error occurs on random days/times.

First I thought it was a problem with the users computer but this happens on two different computers the customer has. One of the computers has Windows 7 professional & Internet Explorer 9. I don't have the setup on the other one.

I have tried with Google Chrome, Firefox 6.0.2, Internet Explorer 9, 8 (browser compatibility mode), 7 (browser compatibility mode) on windows 7 home with no problems at all on my computer.

Here is the form:

<form action="/user/image" method="post" accept-charset="utf-8" class="form_default" enctype="multipart/form-data">
    <fieldset>
        <ol>
            <li>
                <button type="submit" name="save" value="submit" class="button">Save</button>
            </li>
            <li>
                <label for="image">Profile image</label><input type="file" id="image" name="image" />
            </li>
            <li>
                <button type="submit" name="save" value="submit" class="button">Save</button>
            </li>
        </ol>
    </fieldset>
</form>

解决方案

There should be only 1 submit button per form. So keep 1 save button as type="submit" ,change another to type="button"
