04.27.2004 - Remove Children Favelet
I am using M-DOM-I to delete all menus, banners, headers from page before printing. Saves lot's of paper ;) But it is not fun to Alt-Tab to M-DOM-I for every block I am deleting :(
He's using Mozilla's built in DOM Inspector to remove unwanted elements, but its a cumbersome process. He asked that element removal be added to the MODI's functionality, but I thought a new favelet would be better suited. Enter the Remove Children favelet.
What this new favelet does is loop over document.getElementsByTagName("*") and hijacks each elements onclick, onmouseover and onmouseout events. It functions in similar fashion to the MODI with respect to background color highlights, but only adds a title attribute to the element noting what the element is and informing you to click on it to remove it from the DOM. It will also set the href of any <a> tags it comes across to "#" to allow them to be clicked on and removed.
Tested and works in MSIE6, MacIE5.2, Mozilla 1.6 and Firefox 0.8. My version of Safari doesn't support the wildcard argument for getElementsByTagName, but hopefully it works in later versions. Opera 7 doesn't seem to understand what this.parentNode.removeChild(this) means, as doing so in 7.2 on XP and 7.5 on Mac causes it to remove the entire node, parent and all. The mouseover stuff does work, however, so XP Opera users could benefit from this as a light weight MODI...provided they don't click on anything.
Once again, the link for the favelet:Remove Children
This had been added to the Favelet Suite as well.
& lots of thanks for your work
