C# asp.net Gridview中多个文本框的jquery自动完成
我有asp.net Gridview，默认情况下至少有15行带有文本框 aspx WevService.axms 现在，例如，当我在文本框1中键入Engine Work并选择由jQuery AutoCompleteTengine Work填充的值时，然后第二次键入其他文本框文本框2。这只是给我选择发动机工作选项。。这意味着在选择jQuery自动完成填充的任何值后，我无法在其他文本框中选择任何其他值。。。。 示例：-见下图 正如你所见，我输入了Genral工作，但它仍然填充了jquery AutoComplete中以前的值引擎工作，这是我不想要的 如何使用jQuery按CSS类查找文本框 类似这样的东西是通过在GridView中使用jQuery来查找TextBox id的唯一方法，但我需要通过Css类来查找TextBoxC# asp.net Gridview中多个文本框的jquery自动完成,c#,javascript,jquery,asp.net,gridview,C#,Javascript,Jquery,Asp.net,Gridview,我有asp.net Gridview，默认情况下至少有15行带有文本框 aspx WevService.axms 现在，例如，当我在文本框1中键入Engine Work并选择由jQuery AutoCompleteTengine Work填充的值时，然后第二次键入其他文本框文本框2。这只是给我选择发动机工作选项。。这意味着在选择jQuery自动完成填充的任何值后，我无法在其他文本框中选择任何其他值。。。。 示例：-见下图 正如你所见，我输入了Genral工作，但它仍然填充了jquery Auto
var $arrT = $('#<%=gv_Others.ClientID %>').find('input:text[id$="txtEmp"]');
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
});
});
data: "{ 'txt1' : '" + $($arrT).val() + "'}",
这将始终返回数组的第一个值，即第一个文本框，因此它始终将第一个值作为搜索文本提交给您的Web服务。hi@Zach在您回答之前，我已经尝试过了。。。它还在其他文本框中填充以前选择的值。如果您想使用筛选器表达式和筛选器，其中val==@zech如果可以使用筛选器表达式，那么为什么不将第一个文本框的值始终提交给您的Web服务。这是因为您正在将$$arrT.val传递给$.ajax帖子。@zech感谢您给我宝贵的时间，它解决了我的问题。感谢您更新问题。有时候我的眼睛读什么是1+1？我的大脑将其解释为内布拉斯加州的首都是什么？…我使用Asp.Net通用处理程序执行SQL，并将输入的文本作为参数传递给SQL命令。它返回自动完成输入文本的文本框的响应。
