MVC自动完成文本框相关问题！ [英] MVC Auto completion textbox related issue!

问题描述

大家好，使用javasript我设法做了一个自动完成文本框。它在测试应用程序中工作，但是当我将它用于现有应用程序时，控制器方法总是获得空值。我猜javascript函数返回Null值。有没有人对此有所了解？在此先感谢!!!



代码：

 {
 //在Homecontroller 
 
 public JsonResult AutocompleteSuggestions（string serchtext）
 {
 var suggestions = selectEmployees.getEmployeeSuggestedNumbers（serchtext）; 
返回Json（建议，JsonRequestBehavior.AllowGet）; 
} 
 
 // searchtext从View 
 
< script src =<％：Url.Content（〜/ Scripts / jquery）获取Null值-1.4.4.min.js ）％> 中类型= 文本/ JavaScript的 >< /脚本> 
< script src =<％：Url.Content（〜/ Scripts / jquery-ui.min.js）％>类型= 文本/ JavaScript的 >< /脚本> 
 
 
 //在index.aspx 
 
 
< h3 class =searchlabel>搜索< / h3> 
 
< form1 runat =serveraction =method =post> 
< input id =searchTermname =searchTermtype =text/>& nbsp; 
 
< script type =text / javascript> 
 $（function（）{
 $（＃searchTerm）。autocomplete（{
 source：/ Home / AutocompleteSuggestions，
 minLength：1，
 select：function（event，ol）{
 if（ol.item）{
 $（＃searchTerm）。val（ol.item.value）; 
 $（form1 ）.submit（）; 
} 
} 
}）; 
}）; 
< / script> 
 
<％ - <％Html.RenderPartial（〜/ Views / Home / Search.ascx）; ％GT; - ％> 

解决方案

（function（）{

（＃searchTerm ）.autocomplete（{
source：/ Home / AutocompleteSuggestions，
minLength：1，
select：function（event，ol）{
if（ol.item）{

（ ＃SEARCHTERM）VAL（ol.item.value）;

Hi everyone, using javasript I managed to do an auto completion textbox. It worked in the testing app, but when I used it for the existing application, the controller method is always getting a null value. I guess the javascript function is returning a Null value. Does anyone have an idea on this? Thanks in advance!!!

code :

{
//in the  Homecontroller
           
        public JsonResult AutocompleteSuggestions(string serchtext)
        {
            var suggestions = selectEmployees.getEmployeeSuggestedNumbers(serchtext);
            return Json(suggestions, JsonRequestBehavior.AllowGet);
        }

//searchtext getting Null values from the View

<script src="<%: Url.Content("~/Scripts/jquery-1.4.4.min.js")%>" type="text/javascript"></script>
    <script src="<%: Url.Content("~/Scripts/jquery-ui.min.js")%>" type="text/javascript"></script>


      //in the index.aspx


<h3 class="searchlabel">Search</h3>

<form1  runat="server" action = "" method="post">
 <input id="searchTerm" name="searchTerm" type="text" />&nbsp;

     <script type="text/javascript">
         $(function () {
             $("#searchTerm").autocomplete({
                 source: "/Home/AutocompleteSuggestions",
                 minLength: 1,
                 select: function (event, ol) {
                     if (ol.item) {
                         $("#searchTerm").val(ol.item.value);
                         $("form1").submit();
                     }
                 }
             });
         });
    </script>

   <%-- <% Html.RenderPartial("~/Views/Home/Search.ascx"); %>   --%>

解决方案

(function () {

("#searchTerm").autocomplete({ source: "/Home/AutocompleteSuggestions", minLength: 1, select: function (event, ol) { if (ol.item) {

("#searchTerm").val(ol.item.value);
