I have an ExtJS window, with a toolbar at the top, and loads with plain Panel at the bottom with plain HTML. This works fine. On a button click, I'd like to be able to replace the bottom panel (called content), with another panel. If tried this var clickHandler = function(calendar){ // 'content' is the panel id // calendar is also an Ext.Panel object Ext.getCmp('content').update(calendar); }; What am I missing? Update replaces HTML content. You want to remove the old panel and add the new. Try .remove()ing the old panel and .add()ing the new one, and don't forget .doLayout(). 来源： https:/

Recently I've been playing around with different frameworks and libraries, looking for something that really suits my needs. You see, my job mainly involves creating asp.net mvc applications and for most of them using Razor and a little bit of jQuery is enough. But in certain cases and only for a few pages,which are rarely more than one or two per app, I really need something extra that helps me avoid getting entangled in a bunch of jQuery code. As I mentioned, I tried a couple of alternatives and from them, the one I liked the most is Aurelia, because of its simplicity and the fact that it

I'm new to VueJS, so I've been following their official guide . I'm able to trigger the first 5 properties validator, but I can't seem to be able to trigger the last example (custom validation function). my JS file: Vue.component('propValidation', { props: { // basic type check (`null` means accept any type) propA: Number, // multiple possible types propB: String, // a required string propC: { type: String, required: true }, // a number with default value propD: { type: Number, default: 100 }, // object/array defaults should be returned from a // factory function propE: { type: Object, default

How can this snippet code be unit tested using jasmine ? $scope.profileObject = ProfilesSharedObject; $scope.$watch("profileObject.startDate", function() { var startDate = $scope.profileObject.startDate._d; var endDate = $scope.profileObject.endDate._d; var newStartDate = moment(startDate).format("YYYY-MM-DD"); var newEndDate = moment(endDate).format("YYYY-MM-DD"); $scope.startDate = moment(startDate).format("MM/DD"); $scope.endDate = moment(endDate).format("MM/DD/YYYY"); $scope.getSleepData(newStartDate, newEndDate); }); where ProfileSharedObject is a angular js service Watch listeners are

I am reading the syntax for using dojo's declare for class creation. The description is confusing: The declare function is defined in the dojo/_base/declare module. declare accepts three arguments: className, superClass, and properties. ClassName The className argument represents the name of the class, including the namespace, to be created. Named classes are placed within the global scope. The className can also represent the inheritance chain via the namespace. Named Class // Create a new class named "mynamespace.MyClass" declare("mynamespace.MyClass", null, { // Custom properties and

I'm trying to add a button to the column header drop-down menus in my grid. However, I only want to add it to columns with certain itemId. So far I've got it working to add the button to all columns, see code below. I dont see where I could check each column's itemId though, it doesn't seem to iterate through the columns. Is there any workaround for this? Thank you! items:[{ region:'center', xtype:'grid', columns:{ items: COLUMNS, //defined in index.php }, store:'Items', selType: 'checkboxmodel', listeners: { afterrender: function() { var menu = Ext.ComponentQuery.query('grid')[0].headerCt
