The NativeScript Slider component lets the user to drag a
control to select a value. You can set the specific range to use
by setting the component’s minValue
and
maxValue
.
<Slider value="10" minValue="0" maxValue="100" loaded="onSliderLoaded" />
function onSliderLoaded(argsloaded) {
const sliderComponent = argsloaded.object;
sliderComponent.on("valueChange", (args) => {
const slider = args.object;
console.log(`Slider new value ${slider.value}`);
});
}
exports.onSliderLoaded = onSliderLoaded;
import { Slider } from "tns-core-modules/ui/slider";
export function onSliderLoaded(argsloaded) {
let sliderComponent: Slider = <Slider> argsloaded.object;
sliderComponent.on("valueChange", function(args) {
let slider = <Slider>args.object;
console.log(`Slider new value ${slider.value}`);
});
}
<Slider value="10" minValue="0" maxValue="100"
backgroundColor="green" color="red" />
<StackLayout id="stackLayoutId">
<Label text="{{ 'Result: ' + slResult}}" textWrap="true" />
</StackLayout>
function onPageLoaded(args) {
const page = args.object;
const vm = new observableModule.Observable();
const stackLayout = page.getViewById("stackLayoutId");
vm.set("slResult", 22);
// creating new Switch and binding the value property
const options = {
sourceProperty: "age",
targetProperty: "value"
};
const sliderComponent = new sliderModule.Slider();
sliderComponent.bind(options, vm);
// setting slider.value to 22
vm.set("age", 22);
sliderComponent.on("valueChange", (args) => {
vm.set("slResult", args.object.value);
