之前实现AJAX使用Javascript脚本一个一个敲出来的,很繁琐。学习Jquery之后就感觉实现AJAX并不是那么的困难了,当然除了Jquery框架外还有其它的优秀框架这里我就着重说下比较流行的Jquery。Jquery AJAX提交表单有两种方式,一是url参数提交数据,二是form提交(和平常一样在后台可以获取到Form表单的值)。在所要提交的表单中,如果元素很多的话建议用第二种方式进行提交,当然你要是想练练“打字水平”的话用第一种方式提交也未尝不可,相信开发者都不想费白劲吧!废话不多说了贴实例。
首先要下载Jquery、Jquery.form这两个插件,网上很多的!
一:Url参数提交数据
<script type ="text/javascript" src ="../js/jquery.js"></script> <script type="text/javascript"> function checkCorpID()//检测客户编号是否可用 { if($.trim($("#txtF_CORPID")[0].value)=="")//txtF_CORPID是客户编号输入框 { alert("请输入客户编号!"); } else { $("#checkFlag").html("正在检测");//显示提示信息 $.ajax({ type: "get", url: "CheckCorpID.ashx", data: "ID="+$.trim($("#txtF_CORPID")[0].value),//提交表单,相当于CheckCorpID.ashx?ID=XXX success: function(msg){$("#checkFlag").html("");alert( msg ); } //操作成功后的操作!msg是后台传过来的值 }); } } </script>
后台代码:
if(context.Request.Params["ID"].ToString()!="") { Pxt.Logic.SYS.CORP_BASE_INFO cbiL = new Pxt.Logic.SYS.CORP_BASE_INFO(); bool flag=cbiL.checkCorpID(context.Request.Params["ID"].ToString()); if (flag) { context.Response.Write("该客户编号已被占用!"); } else { context.Response.Write("该客户编号可用!"); } }
二:Form提交数据
前台代码:
<script type ="text/javascript" src ="../js/jquery.js"></script> //必须要引用 <script type ="text/javascript" src ="../js/jquery.form.js"></script> //必须要引用 <script type="text/javascript"> // wait for the DOM to be loaded $(document).ready(function() { $('#Tip').hide();//显示操作提示的元素不可见 $('#form1').submit(function()//提交表单 { //alert("ddd"); var options = { target:'#Tip', //后台将把传递过来的值赋给该元素 url:'ReturnVisit.aspx?flag=do', //提交给哪个执行 type:'POST', success: function(){ alert($('#Tip').text());} //显示操作提示 }; $('#form1').ajaxSubmit(options); return false; //为了不刷新页面,返回false,反正都已经在后台执行完了,没事! }); } ); </script> <body> <form id="form1" runat="server"> <div> <table width="100%" border="0" align="center" cellpadding="0" cellspacing="0"> <tr> <td colspan="2" class="tableCategory">客户回访</td> </tr> <tr> <td width="30%" class="tableBg1">客户名称:</td> <td class="tableBg2"> <asp:TextBox ID="txtF_CorpName" runat="server"></asp:TextBox> </td> </tr> <tr> <td width="30%" class="tableBg1">回访主题:</td> <td class="tableBg2"> <asp:TextBox ID="txtF_ReturnVisitTitle" runat="server"></asp:TextBox> </td> </tr> <tr> <td width="30%" class="tableBg1">联系人:</td> <td class="tableBg2"> <asp:TextBox ID="txtF_ContractPerson" runat="server"></asp:TextBox> </td> </tr> <tr> <td width="30%" class="tableBg1">联系人职务:</td> <td class="tableBg2"> <asp:TextBox ID="txtF_ContractPersonPosition" runat="server"></asp:TextBox> </td> </tr> <tr> <td width="30%" class="tableBg1">联系电话:</td> <td class="tableBg2"> <asp:TextBox ID="txtF_ContractPhone" runat="server"></asp:TextBox> </td> </tr> <tr> <td width="30%" class="tableBg1">回访时间:</td> <td class="tableBg2"> <asp:TextBox ID="txtF_ReturnVisitDate" runat="server"></asp:TextBox> </td> </tr> <tr> <td width="30%" class="tableBg1">回访内容:</td> <td class="tableBg2"> <asp:TextBox ID="txtF_ReturnVisitContent" runat="server"></asp:TextBox> </td> </tr> <tr> <td width="30%" class="tableBg1">回访相关文档:</td> <td class="tableBg2"> <asp:TextBox ID="txtF_ReturnVisitFile" runat="server"></asp:TextBox> </td> </tr> <tr> <td width="30%" class="tableBg1"> </td> <td class="tableBg2"> <asp:Button ID="Submit_BT" runat="server" Text="确定" CssClass="button" /> <input type="reset" class="button" value="还原" /> </td> </tr> </table> <span id="Tip"></span> </div> </form> </body>
后台代码:
protected void Page_Load(object sender, EventArgs e) { { if (Request.QueryString["flag"] != null && Request.QueryString["flag"].ToString() == "do") { Pxt.Logic.DBRec.ReturnVisit bll = new Pxt.Logic.DBRec.ReturnVisit(); if (bll.Add(model(0)) > 0) { Response.Write("操作成功!"); Response.End(); } } } } /**//// <summary> /// 根据不同需要,设定模型->获取模型 /// </summary> /// <param name="id">ID值</param> /// <returns></returns> private Pxt.Model.DBRec.ReturnVisit model(int id) { //获取表单值 string F_CorpName = Request.Form["txtF_CorpName"].ToString(); string F_ReturnVisitTitle = Request.Form["txtF_ReturnVisitTitle"].ToString(); string F_ContractPerson = Request.Form["txtF_ContractPerson"].ToString(); string F_ContractPersonPosition = Request.Form["txtF_ContractPersonPosition"].ToString(); string F_ContractPhone = Request.Form["txtF_ContractPhone"].ToString(); DateTime F_ReturnVisitDate = DateTime.Parse(Request.Form["txtF_ReturnVisitDate"].ToString()); string F_ReturnVisitContent = Request.Form["txtF_ReturnVisitContent"].ToString(); string F_ReturnVisitFile = Request.Form["txtF_ReturnVisitFile"].ToString(); string Refer = Session["username"].ToString(); DateTime DoTime = DateTime.Now.Date; Pxt.Model.DBRec.ReturnVisit model = new Pxt.Model.DBRec.ReturnVisit(); if (id > 0)//修改记录,否则表示增加记录 { model.ID = id; } model.F_CorpName = F_CorpName; model.F_ReturnVisitTitle = F_ReturnVisitTitle; model.F_ContractPerson = F_ContractPerson; model.F_ContractPersonPosition = F_ContractPersonPosition; model.F_ContractPhone = F_ContractPhone; model.F_ReturnVisitDate = F_ReturnVisitDate; model.F_ReturnVisitContent = F_ReturnVisitContent; model.F_ReturnVisitFile = F_ReturnVisitFile; model.Refer = Refer; model.DoTime = DoTime; return model; }
注:Jquery.form是Jquery用于帮助操作表单的一个插件,具体的去网上看看教程!
