Run a javascript function after ASP.NET page load is completed
asp.net, c#, javascript, jquery
Solution
try code below, it uses jQuery `document.ready` to run your script after page loads:
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "script", "$(function () { HandleColors(); });", true);
Problem
I need to run a javascript function from ASP.NET code behind AFTER the page is completed. I've used this code so far but it returns "undefined" because the hidden field is not filled with the value when javascript function is fired. What should I do? Thanx in advance. ASPX: ``` <asp:HiddenField runat="server" ID="ColorHiddenField" ClientIDMode="Static" Value="0" /> ``` Javascript: ``` function HandleColors() { alert($('#<%= ColorHiddenField.ClientID %>').val()); } ``` Code Behind: ``` ColorHiddenField.Value = item.Color; ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "script", "HandleColors();", true); ```
