javascript - Catching a textbox value which is stored in a variable -

this controller.

 public class homecontroller : controller   {     public static string commstring = "";      public homecontroller()     {       fwutility.connstring = "data source=.;initial catalog=northwind;uid=sa;password=123";     }      public actionresult index()     {       return view();     }      public static datatable getdata(string customerid)     {       string strfilter = "'" + customerid + "%'";       commstring = "select * customers customerid " + strfilter;       return fwutility.getdatatable(commstring);     } 

this view.

 <script type="text/javascript">         function buttonclick() {             var value = $('#text1').val();             alert('@homecontroller.getdata("d").rows.count.tostring()');         }     </script>     <input type="text" id="text1" value="a" />     <input type="text" id="text2" />     <input type="button" value="show" id="button1" onclick="buttonclick()" /> 

i want catch value stored in textbox , display in alert box, have mentioned "d". in controller have sql query assigned.and here calling controller. out put suppose put "a" inside text box , click button, count of names starting letter "a". this

it's not clear question, assuming want more simple alert(value), then:

i suggest add additional action go getdata function return row count directly:

public actionresult getdatarowcount(string id) {     var count = getdata(id).rows.count;     return new jsonresult                {                    data = new { count },                    jsonrequestbehavior = jsonrequestbehavior.allowget                };  } 

then can use jquery ajax value controller:

<script type="text/javascript">     function buttonclick() {         var value = $('#text1').val();          $.get({             url: '@url.action("getdatarowcount", "home")',             data: { id = value },              success: function(result) {                 alert(result.count);             }         });     } </script> <input type="text" id="text1" value="a" /> <input type="button" value="show" id="button1" onclick="buttonclick()" />
