The Ajax. BeginForm method in ASP. net mvc does not need to submit a new form instance, mvcajax. beginform

Sometimes, you have to consider the following scenarios:

The database table fields change frequently and the popular heavy-service js framework is too dependent on the json data interface. The problem is, database Table change-> data interface change-> previous framework logical change...

If you are not careful, you will find yourself in a pitfall.

In this case, the original pure ASP. net mvc binding method can still be used, because this method does not have to worry about so many js Code.

Sorry, I spoke to myself. I just went straight to the dry goods code ----

Ajax. BeginForm

In the above example, the Ajax. BeginForm method in ASP. net mvc does not need to submit a new form. This is all the content that I have shared with you. I hope you can give me a reference and support the help.
