Sencha touch 2 global variable

After two hours of searching for data, I found that defining variables is so simple that all documents in China are copy, with no technical content;

The data store url I accessed is used to drive the bullet parameters,

1. I define a variable, VAR Params = 'test ';

However, my other JS files have not responded by modifying his values.

2. Ext. Define MyApp. App. config

In the application, requires ['myapp. App. config']

 
MyApp. App. config. getparams ();

I never gave up.

3. Define in the build:

Var_params:
'Test ';

Setparams: function (ARG ){

This. var_params = ARG

}

Getparams: function (){

Retun this. var_params

}

This method does not work either. It has been depressing for a long time.

4. Finally, I found this method in my foreign documents:

Set it:localStorage.setItem('currentUserId',
userID) 

Get it:localStorage.getItem('currentUserId') 

This is a great method. The call is successful!
