JavaScript/jQuery List - Touch-Screen Gestures
The List supports the following touch-screen gestures.
Swipe
Swipe can be used to delete an item or access the commands of the context menu. Performing this gesture raises the itemSwipe event. To handle it, assign a function to the onItemSwipe property, or subscribe to this event using the on(eventName, eventHandler) method.JavaScript- $(function() {
- $("#listContainer").dxList({
- // ...
- onItemSwipe: function(e) {
- // Event handling commands go here
- }
- });
- });
JavaScript- const itemSwipeEventHandler1 = function(e) {
- // First handler of the "itemSwipe" event
- }
- const itemSwipeEventHandler2 = function(e) {
- // Second handler of the "itemSwipe" event
- }
- $("#listContainer").dxList("instance")
- .on("itemSwipe", itemSwipeEventHandler1)
- .on("itemSwipe", itemSwipeEventHandler2)
Long Tap
Long tap can be used to access the commands of the context menu. Performing this gesture raises the itemHold event. To handle it, assign a function to the onItemHold property, or subscribe to this event using the on(eventName, eventHandler) method just like it is demonstrated for the swipe gesture earlier on.You can also specify the time period the UI component should wait before raising the itemHold event. For this purpose, change the itemHoldTimeout property.
JavaScript- $(function() {
- $("#listContainer").dxList({
- // ...
- itemHoldTimeout: 1000 // wait one second before raising the "itemHold" event
- });
- });
Pull Down to Refresh
This gesture refreshes data in the List. To enable it, assign true to the pullRefreshEnabled property.JavaScript- $(function() {
- $("#listContainer").dxList({
- // ...
- pullRefreshEnabled: true
- });
- });
Performing this gesture raises the pullRefresh event. To handle it, assign a function to the onPullRefresh property, or subscribe to this event using the on(eventName, eventHandler) method just like it is demonstrated for the swipe gesture earlier on.
