Question

I am used to doing this in jQuery

$('#RememberMe').attr('checked', true); 

but I can’t remember how to do it in Javascript I thought that

document.getElementById("RememberMe").value = "True"; 

would work, but it doesn’t, it changes the value but does not create the visual check on the html.

I am trying to set the checkbox to on by default. here is the html

<input id="RememberMe" name="RememberMe" type="checkbox" value="false" />   

Answer 1

To change checkbox state try this:

document.getElementById("RememberMe").checked = true;

If you need to change the value of checkbox as an input element use:

document.getElementById("RememberMe").value = "New Value";

However, you can set default value and state in HTML markup:

<input id="RememberMe" name="RememberMe" type="checkbox" value="The Value" checked="checked" />
