实现在text中输入数据，areatext里动态搜索
View Code <th class= " t_r "> 请选择公司： </th> <td width= " 89% " class= " kuang1 "> <asp:TextBox ID= " txtKeyWord " runat= " server "></asp:TextBox> <span class= " red ">*</span><br /> <select id= " txtCompanyList " multiple= " multiple " name= " D1 " οnclick= " CompanySelect() " style= " width: 380px; height: 119px "> <option></option> </select> </td>
JS:
View Code function BindCompanyList() { var comapyname = $("#txtKeyWord").val(); $("#txtCompanyList").html(""); $.getJSON("GetCompanyList.ashx?companyname=" + escape(comapyname), null, function(json) { if (json != null) { $.each(json, function(i) { $("#txtCompanyList").append($("<option></option>").val(json[i].id).html(json[i].companyname)) }); } }); } function CompanySelect() { var Obj = document.getElementById("txtCompanyList"); if (document.getElementById("txtCompanyList").options.length != 0) { document.getElementById("txtKeyWord").value = Obj.options[Obj.selectedIndex].text; } }
ASHX:
View Code public void ProcessRequest(HttpContext context) { StringBuilder sb= new StringBuilder(); if (context.Request.Params["companyname"] != null) { DataTable dt = null; string strcompanyname = context.Server.HtmlDecode(context.Request.Params["companyname"].ToString()); if (strcompanyname!="") { dt = new BLL.CZL_CompanyInfo().GetList(" companyname like '%" + strcompanyname + "%'").Tables[0]; } else { dt = new BLL.CZL_CompanyInfo().GetAllList().Tables[0]; } if (dt == null || dt.Rows.Count == 0) { return; } else { sb.Append("["); for ( int i = 0; i < dt.Rows.Count; i++) { // 返回JOSN数据 sb.Append("{\"id\":\"" + dt.Rows[i]["id"].ToString() + "\",\"companyname\":\"" +Common.ProductAbout.ReturnStr(dt.Rows[i]["companyname"].ToString()) + "\"},"); } sb.Remove(sb.Length - 1, 1); sb.Append("]"); } } context.Response.ContentType = "application/json"; context.Response.ContentEncoding = Encoding.UTF8; context.Response.Write(sb.ToString()); }
注意传递值的时候，js里用escape()对参数进行编码
取得的时候，.cs中用context.Server.HtmlDecode()进行对参数的解密
