Actually,
The following code seems to be working in ie and firefox for me, but it was
a very simple test.
Alex
processScript: function(steps, node) {
steps.push(function(notify) {
if (Wicket.DOM.containsElement(node) ||
Wicket.Head.containsElement(node, "src")) {
notify();
return;
}
var src = node.getAttribute("src");
if (src != null && src != "") {
var script = Wicket.Head.createElement("script");
script.src = src;
var done = false;
// Attach handlers for all browsers
script.onload = script.onreadystatechange = function(){
if ( !done && (!this.readyState ||
this.readyState == "loaded" ||
this.readyState== "complete") ) {
done = true;
var head = document.getElementsByTagName("head");
if (head[0]) {
// how about Wicket.Head.removeElement() ???
head[0].removeChild(script);
}
// maybe I need to do something here?
notify();
}
};
Wicket.Head.addElement(script);
//var onLoad = function() {
// Wicket.Head.addJavascript(content, null, src);
// Wicket.Ajax.invokePostCallHandlers();
// notify();
//}
// we need to schedule the request as timeout
// calling xml http request from another request call stack
doesn't work
//window.setTimeout(function() {
// var req = new Wicket.Ajax.Request(src, onLoad, false,
false);
// req.debugContent = false;
// if (Wicket.Browser.isKHTML())
// req.async = false;
// req.get();
// },1);
} else {
var text = Wicket.DOM.serializeNodeChildren(node);
Wicket.Head.addJavascript(text, node.getAttribute("id"));
notify();
}
});
}
