    • ]]>     Prototype’s stripTags function needs a string as input. If you want to access a dom node with this function, you need to acces the innerHTML, else the input won’t match.

    expl.

    alert($(’mydiv’).stripTags(); -> wont work
    use

    alert($(’mydiv’).innerHTML.stripTags();

  • Prototype: submit multiple select with ajax call
    • ]]>     When using $$ in Prototype, the result is an array. You need to loop through the array to attach the observe function. Expl.
    $$(’.myitems‘).each(function(item) { item.observe(’click’,function(){alert (’clicked’)});});

    or

    $$(’.myitems’).invoke(’observe’, ‘click’, function() {alert(’clicked’)});

    • ]]>     It’s not possible to fire the default events with Prototype 1.6. Only custom events are supported.

    $(’mybutton’).observe(’click’,function(){…});
    $(’mybutton’).fire(’click’); will not work

    $(’myinput’).observe(’input:changed’,function(){….});
    $(’myinput’).fire(’input:changed’); does work
