javascript中没有list，只有array。回调也不可能是list，只能是json数组只有在action中把list转为json，在回调中$.each；script>var arr = [ "one", "two", "three", "four", "five" ];var obj = { one: 1, two: 2, three: 3, four: 4,

<br />对集合一定要判断null,<br />从数据库中取出的数据，不论是持久化对象，还是此对象的一个属性。<br />或者是读取出持久化对象集合，for循环时一定要判断此集合对象的Size，(因为此对象可能从数据库中已经删除掉)<br />要不然，写的代码，代码构成的工程是豆腐渣工程，不健壮，不稳定。

<br />一句话,就是数据的问题，数据库中，老的数据和新的数据不匹配。
