我的asp.net Gridview
默认情况下至少有15行文本框
ASPX
<asp:GridView ID="gv_Others" runat="server" AutoGenerateColumns="false" CssClass="gvothers">
<Columns>
<asp:TemplateField >
<ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
<ItemTemplate >
<asp:TextBox ID="txtEmp" runat="server" Width=100% Height=22px CssClass="txtE"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
aspx.cs(这里我是如何生成15行的GridView
)
private void SetInitialRowsofOthers()
{
var list = new List<string>();
for (int i = 0; i < 16; i++)
{
list.Add(string.Empty);
}
gv_Others.DataSource = list;
gv_Others.DataBind();
gv_Others.HeaderRow.Visible = false;
}
WevService.axms
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public List<string> GetotherServices(string txt1)
{
// your code to query the database goes here
List<string> result = new List<string>();
string QueryString = System.Configuration.ConfigurationManager.ConnectionStrings["autoDBConn"].ToString();
using (SqlConnection obj_SqlConnection = new SqlConnection(QueryString))
{
using (SqlCommand obj_Sqlcommand = new SqlCommand("Select DISTINCT OtherService as txt1 from easy_tblOtherServiceMaster where OtherService like @SearchText + '%' ", obj_SqlConnection))
{
obj_SqlConnection.Open();
obj_Sqlcommand.Parameters.AddWithValue("@SearchText", txt1);
SqlDataReader obj_result1 = obj_Sqlcommand.ExecuteReader();
while (obj_result1.Read())
{
result.Add(obj_result1["txt1"].ToString().TrimEnd());
}
}
}
return result;
}
我想用jQuery autocomplete
填充每个文本框..为此,我创建了一个web服务并从jQuery获取值。
我如何努力完成这项任务:
<script src="js/jquery-1.8.1.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function() {
SearchText();
function SearchText() {
var $arrT = $('#<%=gv_Others.ClientID %>').find('input:text[id$="txtEmp"]');
$($arrT).autocomplete({
source: function(request, response) {
$.ajax({
url: "WebService.asmx/GetotherServices",
type: "POST",
dataType: "json",
contentType: "application/json; charset=utf-8",
data: "{ 'txt1' : '" + $($arrT).val() + "'}",
dataFilter: function(data) { return data; },
success: function(data) {
response($.map(data.d, function(item) {
return {
label: item,
value: item
}
}))
//debugger;
},
error: function(result) {
alert("Error");
}
});
},
minLength: 1,
delay: 1000
});
}
});
</script>
<script type="text/javascript">
$(document).ready(function() {
SearchText();
function SearchText() {
$("#<%=Txt_RegNo.ClientID %>").autocomplete({
source: function(request, response) {
$.ajax({
url: "WebService.asmx/GetAutoCompleteData",
type: "POST",
dataType: "json",
contentType: "application/json; charset=utf-8",
data: "{ 'txt' : '" + $("#<%=Txt_RegNo.ClientID %>").val() + "'}",
dataFilter: function(data) { return data; },
success: function(data) {
response($.map(data.d, function(item) {
return {
label: item,
value: item
}
}))
//debugger;
},
error: function(result) {
alert("Error");
}
});
},
minLength: 1,
delay: 1000
});
}
});
</script>
<script type="text/javascript">
$(function() {
$('input:text:first').focus();
var $inp = $('input:text');
$inp.bind('keydown', function(e) {
//var key = (e.keyCode ? e.keyCode : e.charCode);
var key = e.which;
if (key == 13) {
e.preventDefault();
var nxtIdx = $inp.index(this) + 1;
$(":input:text:eq(" + nxtIdx + ")").focus();
}
});
});
</script>
<script type="text/javascript">
function Load_OtherService() {
var hv = $('input[id$=hdnOthers]');
var $arrT = $('#<%=gv_Others.ClientID %>').find('input:text[id$="txtEmp"]');
var hv1 = "" + hv.val();
var va = hv1.split(',');
for (var j = 0; j < va.length; j++) {
var $txt = $arrT[j];
$($txt).val(va[j]);
}
}
</script>
现在例如当我在TEXTBOX 1中键入“Engine Work”并选择由jQuery autocomplete
填充的值(“Engine Work”)时,我第二次输入其他文本框(TEXT BOX 2) 。它只给我选择“引擎工作”选项..这意味着在选择任何值(由jQuery autocomplete
填充)后,我无法在其他文本框中选择任何其他值....
示例: - (见下图)
如你所见,我输入Genral Work,但它仍然填充了我不想要的jquery AutoComplete中的Previous值“Engine Work”
如何使用jQuery ????
通过CSS类查找TextBox像这样的东西(它只在GridView
里面使用jQuery找到TextBox id,但我需要通过Css Class找到文本框)
var $arrT = $('#<%=gv_Others.ClientID %>').find('input:text[id$="txtEmp"]');
答案 0 :(得分:3)
将脚本块更改为:
$(document).ready(function() {
// This selects all inputs inside the table with the txtE class and applies
// the autocomplete function to them
$('table[id$="gv_Others"] input.txtE').autocomplete({
source: function(request, response) {
$.ajax({
url: "WebService.asmx/GetAutoCompleteData",
type: "POST",
dataType: "json",
contentType: "application/json; charset=utf-8",
data: "{ 'txt1' : '" + request.term + "'}",
dataFilter: function(data) { return data; },
success: function(data) {
response($.map(data.d, function(item) {
return {
label: item,
value: item
}
}))
//debugger;
},
error: function(result) {
alert("Error");
}
});
},
minLength: 1,
delay: 1000
});
});
使用data:
查看ajax帖子中的request.term
- 我更改了选择器。
你的jquery的问题是这一行:
data: "{ 'txt1' : '" + $($arrT).val() + "'}",
这将始终返回数组的第一个值(第一个文本框),因此它始终将第一个值作为搜索文本提交给您的Web服务。
