一个简单的ajax与后台交互的例子

$.ajax({<wbr></wbr>
<wbr><wbr>url:"$_G['PHP_SELF']?mod=$_G['mod']&amp;do=list&amp;catop=get_select&amp;catid="+self.node.id,<br></wbr></wbr><wbr><wbr> type: "POST",<span><wbr></wbr></span></wbr></wbr>
<wbr><wbr>success:function(data){<span><wbr></wbr></span></wbr></wbr>
<wbr><wbr><wbr><wbr>data = data.replace(pidTemp+"'",pidTemp+"' selected=\"true\"");<span><wbr></wbr></span></wbr></wbr></wbr></wbr>
<wbr><wbr><wbr><wbr>oSelectNode.html(data);<span><wbr></wbr></span></wbr></wbr></wbr></wbr>
<wbr><wbr>}<span><wbr></wbr></span></wbr></wbr>
});

可以解决语句先后执行的问题。^_^
