contents.to报错

UI层调用了一个action，如果调用成功，则this.comp('contents2').to(1); 报错：undefined is not a function

把js具体的代码发一下

可以了，谢谢！

tlkj · 发表于 2015-8-13 13:58:19

还有一个问题，我上面发的js代码中，其中有三个下拉框的判断条件。下拉框选空的情况下，判断null或空时，我用==，传入后台的值是“”；我用===，传到后台的值是“undefined”

jishuang · 发表于 2015-8-13 14:01:13

这个是做判断用的，跟传到后台没关系

tlkj · 发表于 2015-8-13 14:22:52

是跟传到后台没关系
1。用==，会有警告
2。现在是用==就可以进入if语句，用===是进入else语句
3。不明白，我应该用==、还是===

jishuang · 发表于 2015-8-13 15:12:21

用===判断undefined

tlkj · 发表于 2015-8-13 15:29:02

默认什么也不选的情况下，点击[查询]按钮，typeData.val('ZDH')的值为什么就成了“undefined”，不应该是null吗
