I need the button “submit” to be disabled unless JavaScript is on.

I tried:

1.

<input onLoad="this.disabled=false" id="post-comment" type="submit" 
value="Post Your Comment" disabled="disabled"/>

2.

<input onLoad="this.removeAttribute('disabled');" id="post-comment" type="submit"
value="Post Your Comment" disabled="disabled"/>

3.

<input onLoad="document.getElementById('post-comment').removeAttribute('disabled');"
id="post-comment" type="submit" value="Post Your Comment" disabled="disabled"/>

Doesn’t work. I’m new to JavaScript, but can’t find answer on the net.

    The problem is that input elements don’t have an “onload” event. The spec shows the available events as:

      onfocus     %Script;       #IMPLIED  -- the element got the focus --
  onblur      %Script;       #IMPLIED  -- the element lost the focus --
  onselect    %Script;       #IMPLIED  -- some text was selected --
  onchange    %Script;       #IMPLIED  -- the element value was changed --
  onclick     %Script;       #IMPLIED  -- a pointer button was clicked --
  ondblclick  %Script;       #IMPLIED  -- a pointer button was double clicked--
  onmousedown %Script;       #IMPLIED  -- a pointer button was pressed down --
  onmouseup   %Script;       #IMPLIED  -- a pointer button was released --
  onmouseover %Script;       #IMPLIED  -- a pointer was moved onto --
  onmousemove %Script;       #IMPLIED  -- a pointer was moved within --
  onmouseout  %Script;       #IMPLIED  -- a pointer was moved away --
  onkeypress  %Script;       #IMPLIED  -- a key was pressed and released --
  onkeydown   %Script;       #IMPLIED  -- a key was pressed down --
  onkeyup     %Script;       #IMPLIED  -- a key was released --

    Since it doesn’t appear as though any of those will help you, you’re probably best off to add the event to the onload of the body element (or through a more robust means, like jQuery’s document ready function). Here’s the quick hack way to do it:

    <body onload="document.getElementById('post-comment').disabled=false">
