javascript常用积累

if(!$( "#handle").is(":animated")){
	//判断元素是否处于动画状态
}

event.stopPropagation();
- 禁止JS报错
	window.onerror = function(){
		return true ; 
}

try {
/*try to do*/
} catch(e){
/*do this if try error */
}

	var res = '' ; 
var obj = eval( obj );
	for( var p in eval( obj ) ){
		var prop = p + ':' + obj[p] + '\n' ; 
		res += prop ; 
	}
	alert( res );

	window.onbeforeunload = function(){
		$(':submit').attr('disabled',true);
	}
