How to make a button unclickable?

[Anil Kumars]

Hi,

I have a few buttons in a webpage. I want to dynamically disable the ability to click on one button. So the button is clickable only if a certain condition is met. Condition is the value of a variable like date or time. Can any one tell me how to do this with javascript?

Thanks in Advance

the_element.dis abled = true; // Disables the button
the_element.dis abled = false; // Enables the button
