2. Inca se mai folosesc pop-up-urile.

function windowOpen(url, opt) {	opt = opt || {};	opt.url = url;	opt.width = opt.width || 500;	opt.height = opt.height || 300;	opt.status = opt.status || 'no';	opt.toolbar = opt.toolbar || 'no';	opt.location = opt.location || 'no';	opt.menubar = opt.menubar || 'no';	opt.directories = opt.directories || 'no';	opt.resizable = opt.resizable || 'no';	opt.scrollbars = opt.scrollbars || 'yes';	opt.name = opt.name || '_blank';	opt.top = opt.top || 20;	opt.left = opt.left || 100;	opt.channelmode = opt.channelmode || 0;	/* and, make it open */	window.open(opt.url, opt.name, 'width='+opt.width+', height='+opt.height+', status='+opt.status+', toolbar='+opt.toolbar+', location'+opt.location+', menubar='+opt.menubar+', directories='+opt.directories+', resizable='+opt.resizable+', scrollbars='+opt.scrollbars+', top='+opt.top+', left='+opt.left+', channelmode='+opt.channelmode);	return false;}// windowOpen('myPage.php', { width:500, height:300, top:30 });

3. Refresh iframe (trebuie sa-i dati un ID)

function iframeRefresh(id, address) {	var ifr = document.getElementById(id);	ifr.src = address;	return false;}// iframeRefresh('myFrmae', 'http://google.com')

4. Easy way to show flash movie

function writeFlash(opt) {	opt = opt || {};	opt.url = opt.url || '';	opt.width = opt.width || 0;	opt.height = opt.height || 0;	opt.wmode = opt.wmode || 'transparent';	opt.flashVars = opt.flashVars || '';	document.write('<'+'object type="application/x-shockwave-flash" data="'+opt.url+'" width="'+opt.width+'" height="'+opt.height+'"'+'>');	document.write('<'+'param name="movie" value="'+opt.url+'" '+'/'+'>');	document.write('<'+'param name="allowScriptAccess" value="always" '+'/'+'>');	document.write('<'+'param name="flashVars" value="'+opt.flashVars+'" '+'/'+'>');	document.write('<'+'param name="wmode" value="'+opt.wmode+'" '+'/'+'>'+'<'+'/'+'object>');	return false;}// writeFlash({ url: 'myMovie.swf',width:300,height:200 })

5. Merge two objects

function mergeObjects(ob1, ob2) {	var attrname;	for (attrname in ob1) {		ob2[attrname] = ob1[attrname];	} return ob2;}// var obj1 = { a:'b', c:'d' };// var obj2 = { m:'b', c:'z' };// var main = mergeObjects(obj1, obj2);// alert(main.c);
