jQuery页面弹出框实现文件上传

如图所示，点击新增，弹出如图的弹出框，点击取消不保存页面信息，点击确定保存页面信息

在前台页面添加一个标签，任何都可以

<div>新增</div>

写弹出框页面

<div></div> <div> <br /> <h1>信息</h1> <div> <div> <div> <hr /> <div></div> <div> <div> <div> 合同名称：<font color="red">*</font><input type="text" value=""><br /> 起始时间：<font color="red">*</font><input type="text" value="" onfocus="WdatePicker({ el: 'txtCStartTime' })">- <input type="text" value="" onfocus="WdatePicker({ el: 'txtCEndTime' })"><br /> 合同附件： <asp:FileUpload runat="server" /> </div> </div> <input type="button" value='新增' /> <input type="hidden" runat="server" /> <div> <p> &nbsp &nbsp &nbsp 人数<font color="red">*</font>： <input type="text" value="" tag="txtNum01">＜X≤ <input type="text" value="" tag="txtNum02"> 比例：<input type="text" value="" tag="txtPercent">% <a>删除</a> </p> </div> </div> </div> </div> <div> <input type="button" value="&nbsp;确定&nbsp;" /> <input type="button" value="&nbsp;取消&nbsp;" /> </div> </div> </div>

通过jQuery控制显示或隐藏

$(function () { //显示DIV $("#divadd").click(function () { var hid = $("#hidValue").val(); if (hid == "") { alert("请先提交信息再新增"); return; } else { $("#popup_container").show(); $("#popup_overlay").show(); } }); //弹窗取消按钮 $("#popup_cancel2").click(function () { $("#popup_container").hide(); $("#popup_overlay").hide(); }); $("#popup_ok2").click(function () { $("#popup_container").hide(); $("#popup_overlay").hide(); var keys = $("[tag='txtNum01']"), values = $("[tag='txtNum02']"), precent = $("[tag='txtPercent']"), len = keys.length, result = [], txt = ""; for (var i = 0; i < len; i++) { txt += keys.eq(i).val() + "," + values.eq(i).val() + "," + precent.eq(i).val() + ";"; } var contractName = $("#txtContractName").val(); var hid = $("#hidValue").val(); var startTime = $("#txtCStartTime").val(); var endTime = $("#txtCEndTime").val(); // var pic = $("#HiddenField2").val(); var fileUpload = $("#fileID").get(0); var files = fileUpload.files; //IE8以及以上浏览器 var data = new FormData(); for (var i = 0; i < files.length; i++) { data.append(files[i].name, files[i]); } data.append("txt", txt); data.append("contractName", contractName); data.append("hid", hid); data.append("startTime", startTime); data.append("endTime", endTime); $.ajax({ //url: "AgentEditSP.aspx/GetData", url: "../Handler/FileAll.ashx", type: "Post", //data: "{'txt':'" + txt + "','contractName':'" + contractName + "','hid':'" + hid + "','startTime':'" + startTime + "','endTime':'" + endTime + "','pic':'" + pic + "'}", data:data, contentType: false, processData: false, success: function (data) { alert("操作成功"); location.href = location.href; }, error: function (err) { alert(err); } }); }); });

这个是点击新增添加新的代理的代码

<script type="text/javascript"> $(function () { $("#btnAdd").click(HandleUDFProperty); function HandleUDFProperty() { if ($("[tag='txtNum01']").size() < 7) { $("#udf_template").clone().find(":text").val("").end().find("a").click(function () { $(this).parents('p').remove(); }).end().appendTo($("#UDFBlock")); } } }); </script>

这个是一般处理程序

public void ProcessRequest(HttpContext context) { var txt = context.Request["txt"]; var contractName = context.Request["contractName"]; var hid = context.Request["hid"]; var startTime = context.Request["startTime"]; var endTime = context.Request["endTime"]; var pic = ""; if (context.Request.Files.Count>0) { var filenames = ""; HttpFileCollection files = context.Request.Files; for (int i = 0; i < files.Count; i++) { HttpPostedFile file = files[i]; filenames =file.FileName; pic = filenames; string fname = context.Server.MapPath("~/Content/Exploitation/" + file.FileName); file.SaveAs(fname); } } // 向ContractDetailSP表插入数据 if (!string.IsNullOrEmpty(txt) && !string.IsNullOrEmpty(contractName) && !string.IsNullOrEmpty(startTime) && !string.IsNullOrEmpty(endTime)) { if (IsExistAgentName(hid) == 0)//判断代理是否存在 { Model.ContractDetailSP condSP = new Model.ContractDetailSP(); condSP.ZID = int.Parse(hid); condSP.Name = GetAgentName(hid); condSP.ParentId = -1; var insertTableName = DB.Context.Insert<Model.ContractDetailSP>(condSP); } if (IsExistContractID(IsExistAgentName(hid), contractName) == 0)//判断合同是否存在 { Model.ContractDetailSP condSP = new Model.ContractDetailSP(); condSP.Name = contractName; condSP.StartTime = DateTime.Parse(startTime); condSP.EndTime = DateTime.Parse(endTime); condSP.ParentId = IsExistAgentName(hid); condSP.ContractPic = pic; var insertTableName = DB.Context.Insert<Model.ContractDetailSP>(condSP); } string[] strrList = txt.Split(';'); foreach (var item in strrList) { string[] templist = item.Split(','); if (templist.Length > 1) { Model.ContractDetailSP condSP = new Model.ContractDetailSP(); condSP.Num1 = int.Parse(templist[0].ToString()); condSP.Num2 = int.Parse(templist[1].ToString()); condSP.PercentNum = decimal.Parse(templist[2].ToString()); condSP.ParentId = IsExistContractID(IsExistAgentName(hid), contractName); var insertTableNum = DB.Context.Insert<Model.ContractDetailSP>(condSP); } } context.Response.ContentType = "text/plain"; context.Response.Write("ok"); } else { //return "请填写完必填项"; context.Response.Write("notall"); } } public bool IsReusable { get { return false; } } private static int IsExistAgentName(string agendID) {//select id from ContractDetailSP where AgentID=2123 int str = 0; var isexist = DB.Context.From<Model.ContractDetailSP>() .Select(a => a.Id) .Where(a => a.ZID == int.Parse(agendID)).ToList(); if (isexist.Count < 1) { str = 0; } else { foreach (var item in isexist) { str = item.Id; } } return str; } private static int IsExistContractID(int id, string contractName) {//select id from ContractDetailSP where ParentId='' and int str = 0; var isexist = DB.Context.From<Model.ContractDetailSP>() .Select(a => a.Id) .Where(a => a.ParentId == id && a.Name == contractName).ToList(); if (isexist.Count < 1) { str = 0; } else { foreach (var item in isexist) { str = item.Id; } } return str; } private static string GetAgentName(string hid) {//select name,* from tblAgent string str = string.Empty; var agent = DB.Context.From<Model.tblAgent>().Select(a => a.name) .Where(a => a.AgentID == int.Parse(hid)).ToList(); foreach (var item in agent) { str = item.name; } return str; }
