文章开始先告诉大家制作jquery实现简洁文件上传表单样式的简易教程。
效果图:
页面结构:
<p class="uploader white"> <input type="text" class="filename" readonly="readonly"/> <input type="button" name="file" class="button" value="Browse..."/> <input type="file" size="30"/> </p>
css文件样式:
.uploader{ position:relative; display:inline-block; overflow:hidden; cursor:default; padding:0; margin:10px 0px; -moz-box-shadow:0px 0px 5px #ddd; -webkit-box-shadow:0px 0px 5px #ddd; box-shadow:0px 0px 5px #ddd; -moz-border-radius:5px; -webkit-border-radius:5px; border-radius:5px; } .filename{ float:left; display:inline-block; outline:0 none; height:32px; width:180px; margin:0; padding:8px 10px; overflow:hidden; cursor:default; border:1px solid; border-right:0; font:9pt/100% Arial, Helvetica, sans-serif; color:#777; text-shadow:1px 1px 0px #fff; text-overflow:ellipsis; white-space:nowrap; -moz-border-radius:5px 0px 0px 5px; -webkit-border-radius:5px 0px 0px 5px; border-radius:5px 0px 0px 5px; background:#f5f5f5; background:-moz-linear-gradient(top, #fafafa 0%, #eee 100%); background:-webkit-gradient(linear, left top, left bottom, color-stop(0%,#fafafa), color-stop(100%,#f5f5f5)); filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#fafafa', endColorstr='#f5f5f5',GradientType=0); border-color:#ccc; -moz-box-shadow:0px 0px 1px #fff inset; -webkit-box-shadow:0px 0px 1px #fff inset; box-shadow:0px 0px 1px #fff inset; -moz-box-sizing:border-box; -webkit-box-sizing:border-box; box-sizing:border-box; } .button{ float:left; height:32px; display:inline-block; outline:0 none; padding:8px 12px; margin:0; cursor:pointer; border:1px solid; font:bold 9pt/100% Arial, Helvetica, sans-serif; -moz-border-radius:0px 5px 5px 0px; -webkit-border-radius:0px 5px 5px 0px; border-radius:0px 5px 5px 0px; -moz-box-shadow:0px 0px 1px #fff inset; -webkit-box-shadow:0px 0px 1px #fff inset; box-shadow:0px 0px 1px #fff inset; } .uploader input[type=file]{ position:absolute; top:0; right:0; bottom:0; border:0; padding:0; margin:0; height:30px; cursor:pointer; filter:alpha(opacity=0); -moz-opacity:0; -khtml-opacity: 0; opacity:0; } input[type=button]::-moz-focus-inner{padding:0; border:0 none; -moz-box-sizing:content-box;} input[type=button]::-webkit-focus-inner{padding:0; border:0 none; -webkit-box-sizing:content-box;} input[type=text]::-moz-focus-inner{padding:0; border:0 none; -moz-box-sizing:content-box;} input[type=text]::-webkit-focus-inner{padding:0; border:0 none; -webkit-box-sizing:content-box;}
javascript部分代码:
<script>$(function(){ $("input[type=file]").change(function(){$(this).parents(".uploader").find(".filename").val($(this).val());}); $("input[type=file]").each(function(){ if($(this).val()==""){$(this).parents(".uploader").find(".filename").val("No file selected...");} }); }); </script>
