问题 If you're using the Ext.js library, how does one do autocomplete in input text areas? More precisely, how would one do autocomplete based on iterative Ajax requests (like the jQuery autocomplete plugin where the Ajax option is set to an updating url). Thoughts are appreciated and thank you for reading. 回答1: Since bmoueskau provided a quite full featured implementation, I thought a more bare-bones example could help. var store = new Ext.data.JsonStore({ url: '/your/ajax/script/', root: 'data',

问题 I am wondering where to add global variables for an ExtJS Application. I already looked at some suggestions in stackoverflow that mention that you can add them inside app.js. But, can anyone be more specific? My app.js looks something like this: Ext.application({ launch: function() {..} }); So, where exactly do the variables go? In the launch function? Outside Ext.application ? 回答1: Declare your own object namespace and add them there: Ext.ns('My.Application.Globals'); My.Application.Globals

问题 I'm trying to figure out how to clone an Ext.data.Store without keeping the old reference. Let me explain better with some code. Here's the source store: var source = Ext.create ('Ext.data.Store', { fields: ['name', 'age'] , data: [ {name: 'foo', age: 20} , {name: 'boo', age: 30} , {name: 'too', age: 10} , {name: 'yoo', age: 80} , {name: 'zoo', age: 30} ] }); Follows an example of what I want to do: var target = source; target.removeAll (); // Here I need to have target empty and source
