利用jquery来隐藏input type="file"

<li>
	<input type="text" name="token" value = "<?php ech$_SESSION['token']; ?>">
	头像：<input type="file"  >
	<img src="<?php echo $result['u_img'] ; ?>"  id = "fileimg" width="100"          height="100" style="border:1px solid #eee">
</li>

<script>
	function _file(){
		$('#file').click();
	}
   $("#fileimg").click(function(){
   	    _file();
   })
</script>
