首先需要引用 js 和css
1 <!--上传控件-->2 <script src="query.form.min.js"></script>3 <link href="Img_List.css" rel="stylesheet" />4 <script src="Img_List.js"></script>
Img_List.js 如下：
1 /// <reference path="../../script/jquery-1.8.0.min.js" /> 2 //显示 3 function imgshow(obj) { 4 //$(obj).find("a").show(); 5 } 6 7 //隐藏 8 function imghide(obj) { 9 //$(obj).find("a").hide();10 }11 12 //上传13 function upload() { 14 $("#FileLoad").click();15 }16 17 //删除18 function imgdel(listId, FileId, hfId) {19 20 $.post("/CommonModule/ashx/public.ashx?action=DelMessageImg&Files=" + $("#" + hfId).val(), function (result) {21 if (result != "ok")22 $.messager.alert("消息提示", "删除失败!");23 });24 var html = "<li><img src=\"/Themes/Images/jia.jpg\" style=\"height: 80px; width: 80px;\" / alt="美观的单张上传控件 一个页面可以实例化多个_html/css_WEB-ITnose" ><input type=\"file\" id=\""+FileId+"\" class=\"input\" onchange=\"ImgUpload('"+FileId+"','"+hfId+"','"+listId+"');\" name=\""+FileId+"\" /></li>"25 $("#"+listId).html(html);26 }27 28 //添加成功29 function imgaddhtml(data, code,listId,fileId,hfId) {30 var list = data.split(',');31 var html = "<li onmouseover=\"imgshow(this)\" onmouseout=\"imghide(this);\">";32 html += "<a style=\"height:80px;width:80px;\" href=\"" + list[0] + "\" target=\"_blank\"><img src=\"" + list[0] + "\" imgs=\"" + list[0] + "\" code=\"" + code + "\" / alt="美观的单张上传控件 一个页面可以实例化多个_html/css_WEB-ITnose" ></a><span onclick=\"imgdel('"+listId+"','"+fileId+"','"+hfId+"')\"></span></li>";33 $("#" + listId).html(html);34 }35 36 //图片文件上传37 //uppath 上传空间id 38 //上传成功存放的图片路径的隐藏域id39 //listId 显示图片的区域id40 function ImgUpload(uppath, hndimg,listId) {41 var sendUrl = "/CommonModule/ashx/Upload_Ajax.ashx?action=SingleFile&IsThumbnail=1&UpFilePath=" + uppath;42 //开始提交43 $("#form1").ajaxSubmit({44 beforeSubmit: function (formData, jqForm, options) {45 //alert(1);46 },47 success: function (data, textStatus) {48 var list = $("#" + hndimg).val();49 $("#" + hndimg).val(data.msgbox);50 imgaddhtml(data.msgbox, 0,listId,uppath,hndimg);51 },52 error: function (data, status, e) {53 alert("上传失败！");54 },55 url: sendUrl,56 type: "post",57 dataType: "json",58 timeout: 60000059 });60 };Img_List.css 如下：
1 .img_list{ margin:0px; padding:0px; overflow:hidden;}2 .img_list ul,.img_list ul li{ margin:0px; padding:0px;} 3 .img_list ul li{ float:left; list-style:none; position:relative; margin:5px 0px 0px 5px;}4 .img_list ul li span5 { position:absolute;top:3px; right:3px; width: 16px; height: 16px; opacity: 0.6;filter: alpha(opacity=60); margin: 0 0 0 2px;6 vertical-align: top; background: url('/Themes/Images/panel_tools.png') no-repeat -16px 0px;}7 .img_list ul li img{ width:80px; height:80px; cursor:pointer; position:relative; z-index:0;}8 .img_list ul li .input{ width:80px; height:80px; cursor:pointer; position:relative; left:-100px;vertical-align: top; margin:0px; padding:0px; opacity:0;filter: alpha(opacity=0); }panel_tools.png 如下：
jia.jpg 如下：
以上素材引用完成后 再看 前台页面代码：
1 <tr> 2 <th>图片1：</th> 3 <td> 4 <asp:Literal ID="ltrimg_list" runat="server"></asp:Literal> 5 <input type="hidden" runat="server" id="ImgPath" name="ImgPath" /> 6 <span style="max-width:90%">建议尺寸(243*150)</span> 7 </td> 8 </tr> 9 10 <tr>11 <th>图片2：</th>12 <td>13 <asp:Literal ID="Literal1" runat="server"></asp:Literal>14 15 <input type="hidden" runat="server" id="hkImgPath" name="hkImgPath" />16 <span style="color:blue;">建议尺寸(243*150)</span>17 </td>18 </tr>
后台页面代码 （初始化控件） ：
1 protected void Page_Load(object sender, EventArgs e) 2 { 3 4 if (!IsPostBack) 5 { 6 ltrimg_list.Text = UpLoad.showUploadFile("File1", "ImgPath", mfmodel.ImgPath, "img_list1"); 7 Literal1.Text = UpLoad.showUploadFile("File2", "hkImgPath", mfmodel.hkImgPath, "img_list2"); 8 9 }10 }生成上传控件方法
