Question

Is there a way to execute a JavaScript function within a loop?

I need to repeatedly call a JavaScript function multiple times. I have attempted to do so in the following way:
In Script

 function changeIt(strgr , idx) {
    //SomeCode
    return;  
 }

In C#

 protected void btn_Click(object sender, EventArgs e)  
 {  
      string strgr = 001;
      for(int i=0; i<3; i++)  
      {  
          base.RunScriptBottom("changeIt(" + strgr + "," + i + ");");  
      }
 }

Unfortunately, the script function is only being called once. What should I do?
Best regards

For more information on ClientScriptManager.RegisterStartupScript, please visit this link

Additionally, you have the option to create a JavaScript function to iterate and call from the server side just once.

 function changeAll(strgr , from, to) {

   for(int i = from, i< to; i++)
      changeIt(strgr ,i);
 }

Server Side:

protected void btn_Click(object sender, EventArgs e)  
 {  
      string strgr = 001;

          base.RunScriptBottom("changeAll(" + strgr + ",0,3);");  

 }

To accomplish this task, it is recommended to incorporate a client event.

<asp:Button Text="click me" runat="server" OnClientClick="executeLoop()" />
<script type="text/javascript">
    function executeLoop() {
        var number = 001;
        for(var i=0; i<3; i++)  
        {  
            performAction(number + "," + i );  
        }
    }
</script>
