Ionic Basics - Programmer All (2023)

collection-repeatIt is a command that allows you to render thousands of items and performance hardly weaken.

This instruction only renders the list of visible areas on the screen. So if you have 1000 list items, only 10 presented on your screen, Collection-repeat will only render ten DOMs in the current scrolling position.

Note Two points: We use ng-style to set the height of the item to match the height of our repetition. In addition, we added a CSS rule to stretch our ITEM to accommodate full screen (because it is absolutely positioned).

<ion-content ng-controller="ContentCtrl"> <div class="list"> <div class="item my-item" collection-repeat="item in items" collection-item-width="'100%'" collection-item-height="getItemHeight(item, $index)" ng-style="{height: getItemHeight(item, $index)}"> {{item}} </div> </div></div>function ContentCtrl($scope) { $scope.items = []; for (var i = 0; i < 1000; i++) { $scope.items.push('Item ' + i); } $scope.getItemHeight = function(item, index) { // Make the index item average 10px, for example return (index % 2) === 0 ? 50 : 60; };}.my-item { left: 0; right: 0;}

<ion-content> <div class="item item-avatar my-image-item" collection-repeat="image in images" collection-item-width="'33%'" collection-item-height="'33%'"> <img ng-src=""> </div></ion-content>.my-image-item { height: 33%; width: 33%;}

This method is called directly when the $ IonicListDelegate service controls all lists. use $getByHandleMethod controls specific IonList instances.

<ion-content ng-controller="MyCtrl"> <button class="button" ng-click="showDeleteButtons()"></button> <ion-list> <ion-item ng-repeat="i in items">> Hello, {{i}}! <ion-delete-button class="ion-minus-circled"></ion-delete-button> </ion-item> </ion-list></ion-content>function MyCtrl($scope, $ionicListDelegate) { $scope.showDeleteButtons = function() { $ionicListDelegate.showDelete(true); };}

Close all open list options buttons.

Ion-checkbox and HTML check boxes are not different, except for its style.

<ion-checkbox ng-model="isChecked">Check box tag</ion-checkbox>

The Radio Directive is not different than HTMLRADIO, except for its style.

Radio behavior is similar to anyAngularJS radio。

usage

<ion-radio ng-model="choice" ng-value="A">Choose A</ion-radio><ion-radio ng-model="choice" ng-value="B">Choose B</ion-radio><ion-radio ng-model="choice" ng-value="C">Choose C</ion-radio>

A switching effect is a switch animation that binds a given boolean model.

Allow the button to drag the switch.

Switching behavior is similar to anyAngularJS checkbox。

usage

The following is connected toairplaneModeModule and associationtoggle-calmAn example of a switching instruction of the CSS-class internal component.

<ion-toggle ng-model="airplaneMode" toggle-class="toggle-calm">Airplane Mode</ion-toggle>

The slider is a component containing a multi-page container, sliding or dragging each page:

The background, Popups, Loading, and other coverage are displayed in the form of the UI.

Typically, multiple UI components require a background, but only one background often needs to be in the DOM.
