基于所需字段类型的Jquery表单验证

时间：2018-05-30 05:34:51

标签： javascript jquery validation

我正在使用jQuery进行表单验证我已经对每个输入字段使用了id's。现在我想添加jquery typeof()方法，如果字段是文本，textarea应该在一个循环中验证，如此电话号码和电子邮件等等。我想用if / else条件写它。这个表格工作正常，除了收音机和复选框没有被验证（提交时应该抛出错误）。但现在我想完全改变我的代码，如上所述。随意告诉是否有任何错误。而且我不想使用任何外部插件。

任何人都可以建议我如何实现？

任何帮助将不胜感激
