样式化input type="file"按钮

你如何风格输入类型=“文件”按钮?

<输入类型=“文件” />

当前回答

一个快速粗暴的方法是将标签设置为按钮，并将位置设置为绝对，这样它就会浮动在原始按钮上，你仍然可以看到文件名。不过，我正在考虑移动解决方案。

我发现这种方法最简单、最轻便。

下面是工作示例:http://codepen.io/c3zar22/pen/QNoYXN

以下是解释:

this would be the markup: <label for="attach-project-file"> <span id="remove-project-file" class="close">x</span> <div class="filename" id="attached-project-file">Click to select a file</div> </label> <input id="attach-project-file" type="file"> hide the input in a hacky way like this: #attach-project-file { width: 0.1px; height: 0.1px; opacity: 0; overflow: hidden; position: absolute; z-index: -1; } style the corresponding label instead [for="attach-project-file"] { /* your styles here */ } style "remove file" button .close { font-size: 16px; padding: 10px; position: absolute; top: 0; right: 0; cursor: pointer; font-style: normal; } .filename element will be used to display the selected file below is the commented JS code needed (using jQuery) to make it work: var $attach = $('#attach-project-file'), $remove = $('#remove-project-file'), $name = $('#attached-project-file'); // initially hide the remove button $remove.hide(); // do this when file input has changed // i.e.: a file has been selected $attach.on('change', function() { var val = $(this).val(); if (val !== '') { // if value different than empty // show the file name as text // hide/text/fadeIn creates a nice effect when changing the text $name .hide() .text(val) .fadeIn(); // show the remove button $remove.fadeIn(); } else { // if value empty, means the file has been removed // show the default text $name .hide() .text('Click to select a file') .fadeIn(); // hide remove button $remove.fadeOut(); } }); // remove selected file when clicking the remove button // prevent click bubbling to the parent label and triggering file selection $remove.on('click', function(e) { e.preventDefault(); e.stopPropagation(); $attach .val('') .change(); // trigger change event });

Jquery版本的teshguru脚本自动检测输入[文件]和样式

<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.min.js"></script>
<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">
$(document).ready(function()
{
    $('input[type=file]').each(function()
    {
        $(this).attr('onchange',"sub(this)");
        $('<div id="yourBtn" onclick="getFile()">click to upload a file</div>').insertBefore(this);
        $(this).wrapAll('<div style="height: 0px;width: 0px; overflow:hidden;"></div>');
    });
});
 function getFile(){
   $('input[type=file]').click();
 }
 function sub(obj){
    var file = obj.value;
    var fileName = file.split("\\");
    document.getElementById("yourBtn").innerHTML = fileName[fileName.length-1];
 }
</script>
</head>
<body>
<?php 
    var_dump($_FILES);
?>
<center>
<form action="" method="post" enctype="multipart/form-data" name="myForm">

<input id="upfile" name="file" type="file" value="upload"/>
<input type="submit" value='submit' >
</form>
</center>
</body>
</html>

你可以创建一个很棒的(未完成的)文件上传器到<button>元素或任何其他元素:

函数selectFile() { . getelementbyid (fileSelector) .click (); ｝输入# fileSelector (type = "文件"){ 显示:没有; ｝按钮onclick * =”()”){ 光标:指针; ｝ <input type="file" id="fileSelector"> <按钮onclick = " selectFile ()>选择文件从计算机

当点击有样式的<div>时，只需使用trigger()函数模拟点击<input>。我在<div>中创建了自己的按钮，然后在点击我的<div>时触发了输入上的单击。这允许你创建你想要的按钮，因为它是一个<div>，模拟点击你的文件<input>。然后在<input>上使用display: none。

// div styled as my load file button
<div id="simClick">Load from backup</div>

<input type="file" id="readFile" />

// Click function for input
$("#readFile").click(function() {
    readFile();
});

// Simulate click on the input when clicking div
$("#simClick").click(function() {
    $("#readFile").trigger("click");
});

我在这里找到了一个使用jQuery的非常聪明的解决方案，它可以在所有旧浏览器和新浏览器中工作。它使用实际的文件浏览按钮来处理所有样式和click()问题。我做了一个简单的javascript版本:小提琴解决方案非常简单，就像天才一样:让文件输入不可见，然后用一段代码把它放在mousecursor下面。

<div class="inp_field_12" onmousemove="file_ho(event,this,1)"><span>browse</span>
    <input id="file_1" name="file_1" type="file" value="" onchange="file_ch(1)">
</div>
<div id="result_1" class="result"></div>
<script>
    function file_ho(e, o, a) {
        e = window.event || e;
        var x = 0,
        y = 0;
        if (o.offsetParent) {
            do {
            x += o.offsetLeft;
            y += o.offsetTop;
            } while (o = o.offsetParent);
        }
    var x1 = e.clientX || window.event.clientX;
    var y1 = e.clientY || window.event.clientY;
    var le = 100 - (x1 - x);
    var to = 10 - (y1 - y);
    document.getElementById('file_' + a).style.marginRight = le + 'px';
    document.getElementById('file_' + a).style.marginTop = -to + 'px';
    }
</script>
<style>
    .inp_field_12 {
        position:relative;
        overflow:hidden;
        float: left;
        width: 130px;
        height: 30px;
        background: orange;
    }
    .inp_field_12 span {
        position: absolute;
        width: 130px;
        font-family:'Calibri', 'Trebuchet MS', sans-serif;
        font-size:17px;
        line-height:27px;
        text-align:center;
        color:#555;
    }
    .inp_field_12 input[type='file'] {
        cursor:pointer;
        cursor:hand;
        position: absolute;
        top: 0px;
        right: 0px;
        -moz-opacity:0;
        filter:alpha(opacity=0);
        opacity: 0;
        outline: none;
        outline-style:none;
        outline-width:0;
        ie-dummy: expression(this.hideFocus=true);
    }
    .inp_field_12:hover {
        background-position:-140px -35px;
    }
    .inp_field_12:hover span {
        color:#fff;
    }
</style>
