    Are all events supported in browser

    I am trying to attach a "onblur" event on the body element. IE does'nt throw any errors but the event is not captured by the browser when the onblur occurs on the elements withing the body.

    But if I attach a "onclick" event. That is captured by the browser.

    Any idea ?

      You would need to check the specific browsers DOM reference to see if that event is supported in the body tag. Even if it is how would that event ever be triggered? The entire page would some how have to lose focus.

      The only way I can think of for that to happen would be for you to have content outside of the body tags would would not follow correct syntax, and would risk not being rendered correctly.

          Isn't that the event propogation concept. ex.

          <div onClick="someFu nction()">
          <a href="www.a.com ">
          <a href="www.b.com ">
          </div>

          If I attach the onclick event to the div then every click on the href element will be captured

              Not all events bubble- focus, blur, scroll, resize, and error do not, nor do most of the advanced events- mutation, textrange, treewalker.


              To get a complete list, get a good book or find a good tutorial.

                      This is exactly my point! Since all content in a properly formated HTML page goes inside the body tag, it does not matter what you click on or move the mouse to. The focused element(s) will always be inside the body tag so it should always contain the focused element.

                      [HTML]
                      <body onBlur="someFun tion()" >
                      <span>Blah Blah Blah</span><br /><br /><br />
                      <span>Blah Blah Blah</span><br /><br /><br />
                      <span>Blah Blah Blah</span><br /><br /><br />
                      <span>Blah Blah Blah</span><br /><br /><br />
                      </body>
                      [/HTML]
