ASP.NET Get a CheckBox value from javascript

11:54 PM , , , 0 Comments

Recently I needed to access the value of a CheckBox from javascript.
Because CheckBox doesn't have a Value property I tried the following:
myCheckBox.Attributed.Add("value", "test");
And tried to access it from javacstipt:
alert($("myCheckBox").value)
I was surprised to find out that the message in the alert was "on" and not "test" as I expected so I looked at the source of the page and this is what I saw:
As you can see the value I set on the server side code doesn't appear in the result html code.
After a little more research I found out there is a property for the CheckBox that is called "InputAttributes" - this property adds the attributes to the CheckBox input.
This is the correct code:
myCheckBox.InputAttributes.Add("value", "test");
That's all I needed.
Happy coding.
