How to get checkbox1.Checked property within a javascript?
asp.net, javascript
Solution
`OnCheckedChanged` is a server side event, and you are handing it on the client side.
<asp:CheckBox ID="CheckBox1" runat="server" onchange="validate();" />
<asp:CheckBox ID="CheckBox2" runat="server" onchange="validate();" />
Also you might need to use `.ClientID` -
(document.getElementById('<%=CheckBox1.ClientID%>').checked && document.getElementById('<%=CheckBox2.ClientID%>').checked)
Problem
I have two checkboxes.when i checked both the checkboxes i wants to generate an alert "Passed". I have written like this ``` <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>Untitled Page</title> <script type="text/javascript" > function validate() { if (document.getElementById('CheckBox1').checked && document.getElementById('CheckBox2').checked) { alert("passed"); } else { alert("Referred") } } </script> <asp:CheckBox ID="CheckBox1" runat="server" OnCheckedChanged="javascript:validate();" /> <asp:CheckBox ID="CheckBox2" runat="server" OnCheckedChanged="javascript:validate();" /> ``` but the problem is this (checkbox1).checked is not getting inbuildly within the .how can i get it? is ther any need for adding extra properties to my project for getting the '.checked' property?its first time i'am using javascript. and my visualstudio version is 3.5.please help
