jquery submit() 提交失败

今天写一个表单提交

居然走到$('#wechat_form').submit() 这，但怎么都没有提交这个表单

google 了一下

Additional Notes:
Forms and their child elements should not use input names or ids that conflict with properties of a form, such as submit, length, or method. Name conflicts can cause confusing failures. For a complete list of rules and to check your markup for these problems, see DOMLint.

原因是因为我submit的按钮的id 也是submit 和提交submit()方法同名。

解决方案：

　　改掉按钮的id 名，就可以了。
