Use knockout to bind a simple JSON object

Recently, Ko's Js framework seems to be on fire, so I simply learned the reference in the garden.Article:

Bind Object Data

 

HTML form:

 
<Form ID = "xxoo"> name: <input type = "text" data-bind = "value: truename" name = "truename" id = "txttruename"/> Email: <input type = "text" data-bind = "value: email" name = "email" id = "txtemail"/> </form>
 

There are many other attributes, so I won't skip them here ~~~

 

JS Code:

To use Ko for data binding, you must construct an object suitable for Ko. The method is as follows:

 
VaR viewmodel = {truename: KO. observable ("Crazy talent"), email: KO. objservable ('2017 @ QQ.com ')}
 

Of course, we are at the backendCodeYou can also generate such JSON. If it is not related to the back-end writeProgram, Using JSON. Net to generate a JSON object does not match Ko. So

We need to construct an object in JS at the front end into an object suitable for Ko. You can write it as shown above, but it is annoying if there are many attributes, so we can write a general method.

Practice:

 
Function binddata (modelobj) {If (modelobj) {var viewmodel ={}; for (VAR item in modelobj) {viewmodel [item] = Ko. observable (modelobj [item]);} Ko. applybindings (viewmodel );}}
 

That's all. I'm not afraid of any attributes you have ~~, Write it in one way! Effort-saving!

The above method may have problems with your logic. You can make some modifications. This should be hard for you. I am optimistic about you!
