How do I activate or deactivate the button according to the value of the variable?

advertisements

I use pure javascript. I have this row in my asp page:

<input type="button" value="..." id="ffcolorswtach" style="width: 20px; height: 19px; position: relative; left: 15px; top: 0px; color: #ff0000; background-color: #d8d5d5;" onclick="PickColor(1, false, false)" role="button" />

Also I have javascript variable in my client page that contains true/false values:

var isColorSelected

When isColorSelected is false i want to enable input element above if false I want to disable it.Any idea how can I implement it?

Try something like the following:

    if(isColorSelected != true)
      document.getElementById("ffcolorswtach").disabled = true;
    else
      document.getElementById("ffcolorswtach").disabled = false;

This is finding that element within the DOM and using the built in browser capability to disable the element for you.
