cursor：pointer属性不适用于Webkit浏览器中的文件上传按钮 [英] The cursor:pointer property doesn't apply to file upload buttons in Webkit browsers

问题描述

我有CSS代码，并不真正工作在webkit浏览器，如safari和chrome

如果你想在这里的实例是 http://jsfiddle.net/mnjKX/1/

我有此CSS代码

  .file-wrapper {
 cursor：pointer; 
显示：inline-block; 
 overflow：hidden; 
 position：relative; 
} 
 .file-wrapper输入{
 cursor：pointer; 
 font-size：100px; 
 height：100％; 
 filter：alpha（opacity = 1）; 
 -moz-opacity：0.01; 
 opacity：0.01; 
 position：absolute; 
 right：0; 
 top：0; 
} 
 .file-wrapper .button {
 background：＃79130e; 
 -moz-border-radius：5px; 
 -webkit-border-radius：5px; 
 border-radius：5px; 
 color：#fff; 
 cursor：pointer; 
 display：inline-block; 
 font-size：11px; 
 font-weight：bold; 
 margin-right：5px; 
 padding：4px 18px; 
 text-transform：uppercase; 
} 
  

和此HTML代码：

 < span class =file-wrapper> 
< input type =filename =photoid =photo/> 
< span class =button>选择照片< / span> 
< / span> 
  

此代码显示隐藏的输入文件标记，
这里的问题是游标：指针在webkit浏览器上不起作用，

我如何解决它或绕过/超过这个？

解决方案

对于初学者，如果您从输入中删除​​ height >规则。

但这个透明的输入字段是一个黑客的地狱...我不会'

更新： $ b

这里是正确的解决方案：

  ::  -  webkit-file-upload-button {cursor：pointer ; } 
  

我认为文件上传按钮不可访问，但Chrome的用户代理样式表证明我的错误：）

i have CSS code that does not really work on webkit browsers such as safari and chrome

if you want live example here it is http://jsfiddle.net/mnjKX/1/

i have this CSS code

.file-wrapper {
    cursor: pointer;
    display: inline-block;
    overflow: hidden;
    position: relative;
}
.file-wrapper input {
    cursor: pointer;
    font-size: 100px;
    height: 100%;
    filter: alpha(opacity=1);
    -moz-opacity: 0.01;
    opacity: 0.01;
    position: absolute;
    right: 0;
    top: 0;
}
.file-wrapper .button {
    background: #79130e;
    -moz-border-radius: 5px;
    -webkit-border-radius: 5px;
    border-radius: 5px;
    color: #fff;
    cursor: pointer;
    display: inline-block;
    font-size: 11px;
    font-weight: bold;
    margin-right: 5px;
    padding: 4px 18px;
    text-transform: uppercase;
}

and this HTML code :

<span class="file-wrapper">
   <input type="file" name="photo" id="photo" />
   <span class="button">Choose a Photo</span>
</span>

this code shows hidden input file tag , the problem here is that the cursor:pointer is does not work on webkit browsers ,

how can i solve it or bypass / overtake this ?

解决方案

For starters, it works in Chrome if you remove the height declaration from the input rule.

Live demo: http://jsfiddle.net/mnjKX/16/

But this transparent input field is a hell of a hack... I wouldn't rely on it.

Update:

And here is the proper solution:

::-webkit-file-upload-button { cursor:pointer; }

I thought the file upload button is unreachable, but Chrome's user agent style sheet proved my wrong :)
