问题 I am using border layout in ExtJs 4 wherein the east panel is a collapsible panel. When I expand the panel it forces the center panel to adjust (shrink). Similarly When the east panel is collapsed the center panel retracts. The desired behavior is that when I expand the east panel it should float over the center panel and not force it to adjust itself. How can I achieve this? 回答1: Set the floatable: true config option on the east panel. See also the Border layout example. 来源： https:/

问题 I'm building an app that should run on mobile/tablet/pc. And the main feature contains an enormous list of items that I'm getting from json file hosted on another server. Currently I'm working on a PC and the list takes about a minute to populate (over 800 objects, the number grows everyday), I'm guessing that's because it takes time to generate the markup for 800 divs... Note: I'm working locally, when this is online it would be a nightmare, overkill.. My thoughts were to get all the data

问题 This question already has answers here : ExtJS. Hide all components within a container (3 answers) Closed 5 years ago . Consider: Ext.Array.each(myContainer.query('> *'), function(cmp) { cmp.hide(); }); Is there a better way? 回答1: Your approach uses a query which takes more resources. A more efficient way may be just: Ext.each(myContainer.items.items, function(cmp) { cmp.hide(); }); Since you already have a reference to myContainer, there's no point of querying for its children as you already
