I noticed that if I set the checked attribute on a radio button before I attach it to the DOM, IE7 will not show the button as checked when it is indeed appended to the DOM. It may happen to other IE versions too.
var r = new Element( 'input', { type: 'radio' } ); if (someCondition) { r.writeAttribute('checked', 'checked'); } $$('body').first.appendChild(r); The only way to fix it for all browsers is to bypass Prototype and do plain DOM manipulation with the defaultChecked attribute: r.defaultChecked = true; Is this a problem with Prototype or my problem? I thought the writeAttribute function was supposed to handle cross browser compatibility. -- You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.
