问题 I've the following problem / question in ExtJs 2.3: I'd like to do a search within a combobox.

问题 The code I wrote runs absolutely fine on the browser. But when I connect to wifi on the iPhone I get an error in the debugger : Javascript Error - Can't find variable : google This occurs whenever I call any google maps/directions/geoLocation object.

问题 I am curious as to why the record contained in the result set of a Model.save() response does not properly return updated associated data, despite the updated data being contained in the server response... Example Model & Store Definition: Ext.define("App.model.test.Parent",{ extend: 'Ext.data.Model', requires: ['App.model.test.Child'], fields: [ {name: 'id', type: 'int' }, {name: 'name', type: 'string'}, {name: 'kids', type: 'auto', defaultValue: []} ], idProperty: 'id', hasMany: [{

问题 I've just started developing an ExtJS application that I plan to support with a very lightweight JSON PHP service. Other than that, it will be standalone. My question is, what is the best way to organize the files and classes that will inevitably come into existence?

问题 I have an ExtJS DataView with following template: <ul> <tpl for="."> <li class="report-field" id="{listId}"> {[this.getReorderLinks(values, xindex, xcount)]} <span class="field-title small" data-qtip="{displayName}">{displayName}</span> <i class="field-remove" title="' + deleteLabel + '"></i> </li> </tpl> </ul> Which makes each list of items look like this: Where user can click on different icons and perform related action, moving up/down in order and remove. Note that these items are added
