How to Call a Server side Function on the Client side Pin

Good Day All


i have a Function e.g

Code:

---

public String Getdata(String mystr)

{

//Do what ever

//return  a String

}

---

and i want to call this function and pass data in Javascript like this

Code:

---

function KeyPress() {
            var TExtbox1 = document.getElementById('Text1');
       
        if (TExtbox1.value.length == 2) {

        //call the function here and pass the textbox1 value. 

  return false;
        }
        }

Thanks

Take a look at this. I believe that is wat you're looking for.

Good Day Danny

Thank you for your kind Replies. This is what i have done so far


i have a HTML textbox defined like this

Code:

---

<input type="Text" id="Text1" onkeypress="keyPress()" />

---

and on the Server side , i am using page method , i have a function that is defined like this

Code:

---


  [WebMethod, System.Web.Script.Services.ScriptMethod]
    public static string Getadata(String Data)
    {
      String Scriptt  = Data;
      return Scriptt;
    }

---

and i access this method like this on the client side

Code:

---


  function keyPress() {
          var tb = document.getElementById('Text1');
          if (tb.value.length == 2)
              PageMethods.Getadata(tb.value, myFunction);
          return false;
      }
      function myFunction(msg) {
          alert(msg);
      }

---

and its working fine, but now i want to know how to use this in a normal asp.net textbox , because it does not have a keypress event and the defination of the textbox is like this

Code:

---

<asp:TextBox ID="Text2" runat="server"></asp:TextBox>

---

Thanks

Have you tried something like this :

Code:

---

<asp:textBox id=myID onkeypress="javascript:keypress()">

---

Also, vuyiswam, your signature is too long, it breaks up post - flow. Please try to shorten it. Thank you.

Good Day

My javascript looks like this

Code:

---

 
<script type="text/javascript">
      function keyPress() {
          var txt2 = document.getElementById("<%=txt2p%>");
          alert(txt2);
          if (txt2.value.length <= 2)
          { 
              PageMethods.Getadata(txt2.value, myFunction);
          }
          return false;
      }
      function myFunction(msg) {
          alert(msg);
      }
  </script>

the asp.net textbox does not a .value property in javascript

Thanks

Is this a new question or what??

I suggest you study up on the JavaScript DOM. Do a google search on that ;)

You can get the value of a textbox with JavaScript, like this :

Code:

---

document.getElementById(id).value

---

Please, I'm asking nicely, and the last time, edit your signature to be shorter, please.
