javascript - How to call function from textbox using asp.net? -


i have been trying call function formatdate(). try put text = "" / value = "" doesn't return correctly.

how can fix this?

<asp:content id="content1" contentplaceholderid="contentplaceholder1 runat="server">     <script type="text/javascript">         function formatdate(date) {             var d = new date(date),             month = '' + (d.getmonth() + 1),             day = '' + d.getdate(),             year = d.getfullyear();             year = year.tostring().substr(2, 2);             daterecord = [year, month].join('/');             return daterecord         }     </script>      <h2><asp:label id="lblpagename" text="project seq code" runat="server" /></h2>      <table width="625" cellpadding="0" cellspacing="1" style="margin-left:180px;">         <tr>             <td>&nbsp;report </td>             <td><asp:textbox id="txtreport" text="return formatedate(date)" runat="server" width="250px" />             </td>         </tr>     </table> </asp:content>

this might solution problem. haven't tested out, i'm working same thing. i'm doing other way around, using html inputs jquery , asp server side code access controls well.

<asp:content id="content1" contentplaceholderid="contentplaceholder1 runat="server">            <script type="text/javascript">             function formatdate(date) {                 var d = new date(date),                     month = '' + (d.getmonth() + 1),                     day = '' + d.getdate(),                     year = d.getfullyear();                     year = year.tostring().substr(2, 2);                     daterecord = [year, month].join('/');                     $("#txtreport").val(daterecord);             }         </script>      <h2><asp:label id="lblpagename" text="project seq code" runat="server" /></h2>          <table width="625" cellpadding="0" cellspacing="1" style="margin-left:180px;">          <tr>              <td>&nbsp;report </td>              <td><asp:textbox id="txtreport" clientidmode="static" runat="server" width="250px" />               </td>          </tr>         </table> </asp:content>

instead of calling function place text (which don't know if possible, be), try placing text jquery.

you might need change asp control this:

<asp:textbox id="txtreport" clientidmode="static" runat="server" width="250px"></asp:textbox>

clientidmode make sure id assigned element used, instead of generated id asp.

edit tested , code. works without problem, difference "date" variable hard-coded because needed example. included link jquery , put scripting code in header. wanted?
