The context menu (right-clicking) for the image above is disabled (except
in Opera). For the JavaScript to work the image must have class="protect".
This image (above) does not have the context menu disable because it does
not have class="protect".
One more thing you need to do to thwart IE users is to disable the image toolbar. Add the following meta tag to your page:
<meta http-equiv="imagetoolbar" content="no">
function disableContextMenu() { // grab all images and loop through them checking for the class to have "protect" in it. // This function won't work in Opera becuase it doesn't support .oncontextmenu var images = document.getElementsByTagName("img"); for(var i=0;i<images.length;i++) { //get the image's class and see if "protect" is in it if(images[i].className.indexOf("protect") != -1 ) { // disable the context menu for this image. images[i].oncontextmenu=function(){return false;}; } } }
The only change you need to make to disable all context menus for all images is to remove the if statement that checks for class names.
function disableContextMenu() { // grab all images and loop through them. // This function won't work in Opera becuase it doesn't support .oncontextmenu var images = document.getElementsByTagName("img"); for(var i=0;i<images.length;i++) { // disable the context menu for this image. images[i].oncontextmenu=function(){return false;}; } }
