>按照以下步骤，您可以为文件上传表单创建自定义样式：
Follow these steps then you can create custom styles for your file upload form:
1）这是简单的HTML表单（请阅读我在这里写的HTML注释
1.) This is the simple HTML form(please read the HTML comments I have written here bellow)
<form action="#type your action here" method="POST" enctype="multipart/form-data">
<div id="yourBtn" style="height: 50px; width: 100px;border: 1px dashed #BBB; cursor:pointer;" onclick="getFile()">Click to upload!</div>
<!-- this is your file input tag, so i hide it!-->
<div style='height: 0px;width: 0px; overflow:hidden;'><input id="upfile" type="file" value="upload"/></div>
<!-- here you can have file submit button or you can write a simple script to upload the file automatically-->
<input type="submit" value='submit' >
</form>
2）然后使用这个简单的脚本将点击事件传递给文件输入标签。 >
2.) Then use this simple script to pass the click event to file input tag.
function getFile(){
document.getElementById("upfile").click();
}
现在，您可以使用任何类型的样式，而不必担心如何更改默认样式。
我知道这很好，因为我一直试图改变默认样式为一个半月。相信我很难，因为不同的浏览器有不同的上传输入标签。因此，使用这一个来构建您的自定义文件上传表单。这是完整的AUTOMATED UPLOAD代码。
Now you can use any type of a styling without worrying how to change default styles. I know this very well, because I have been trying to change the default styles for month and a half. believe me it's very hard because different browsers have different upload input tag. So use this one to build your custom file upload forms.Here is the full AUTOMATED UPLOAD code.
<html>
<style>
#yourBtn{
position: relative;
top: 150px;
font-family: calibri;
width: 150px;
padding: 10px;
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border: 1px dashed #BBB;
text-align: center;
background-color: #DDD;
cursor:pointer;
}
</style>
<script type="text/javascript">
function getFile(){
document.getElementById("upfile").click();
}
function sub(obj){
var file = obj.value;
var fileName = file.split("\\");
document.getElementById("yourBtn").innerHTML = fileName[fileName.length-1];
document.myForm.submit();
event.preventDefault();
}
</script>
<body>
<center>
<form action="#type your action here" method="POST" enctype="multipart/form-data" name="myForm">
<div id="yourBtn" onclick="getFile()">click to upload a file</div>
<!-- this is your file input tag, so i hide it!-->
<!-- i used the onchange event to fire the form submission-->
<div style='height: 0px; width: 0px;overflow:hidden;'><input id="upfile" type="file" value="upload" onchange="sub(this)"/></div>
<!-- here you can have file submit button or you can write a simple script to upload the file automatically-->
<!-- <input type="submit" value='submit' > -->
</form>
</center>
</body>
</html>
