思路:
input file上传按钮的美化思路是,先把之前的按钮透明度opacity设置为0,然后,外层用div包裹,就实现了美化功能。
代码如下:
DOM结构:
<a href="javascript:;" class="a-upload"> ???<input type="file" name="" id="" accept="image/png,image/jpeg">点击这里上传文件</a><a href="javascript:;" class="file">选择文件 ???<input type="file" name="" id=""></a>
CSS样式1:
/*a ?upload */.a-upload { ???padding: 4px 10px; ???height: 20px; ???line-height: 20px; ???position: relative; ???cursor: pointer; ???color: #888; ???background: #fafafa; ???border: 1px solid #ddd; ???border-radius: 4px; ???overflow: hidden; ???display: inline-block; ???*display: inline; ???*zoom: 1}.a-upload ?input { ???position: absolute; ???font-size: 100px; ???right: 0; ???top: 0; ???opacity: 0; ???filter: alpha(opacity=0); ???cursor: pointer}.a-upload:hover { ???color: #444; ???background: #eee; ???border-color: #ccc; ???text-decoration: none}
样式2:
.file { ???position: relative; ???display: inline-block; ???background: #D0EEFF; ???border: 1px solid #99D3F5; ???border-radius: 4px; ???padding: 4px 12px; ???overflow: hidden; ???color: #1E88C7; ???text-decoration: none; ???text-indent: 0; ???line-height: 20px;}.file input { ???position: absolute; ???font-size: 100px; ???right: 0; ???top: 0; ???opacity: 0;}.file:hover { ???background: #AADFFD; ???border-color: #78C3F3; ???color: #004974; ???text-decoration: none;}
修改后如下:
样式二:
美化后显示文件名
上面美化,把默认显示的文件名也给隐藏掉了,那么如何显示文件名称呢?没关系,我们可以用jquery来获取文件的文件名。
我们可以写个change事件
$(".a-upload").on("change","input[type=‘file‘]",function(){ ???var filePath=$(this).val(); ???if(filePath.indexOf("jpg")!=-1 || filePath.indexOf("png")!=-1){ ???????$(".fileerrorTip").html("").hide(); ???????var arr=filePath.split(‘\\‘); ???????var fileName=arr[arr.length-1]; ???????$(".showFileName").html(fileName); ???}else{ ???????$(".showFileName").html(""); ???????$(".fileerrorTip").html("您未上传文件,或者您上传文件类型有误!").show(); ???????return false ????}})
