NativeScript-Dom

ProPlugins

We have an awesome, new service in town! This service provides tested new and upgraded plugins. All ProPlugins are already known to work with NativeScript 6.x. If you are interested in getting the latest, known working, and enhanced plugins; check out https://ProPlugins.org -- because I strongly believe in what ProPlugins offers the community all of my development work is being done on the ProPlugins version.

Community

Please feel free to continue to use this version of the plugin, it is now 100% being maintained by YOU the community, and as such I will gladly continue to support the community version by accepting any/all PR's for this plugin and publish it. I will attempt to verify the PR doesn't have any backdoors; but I won't be doing any testing, so if it is broken it is up to you to send a PR!

Updates

Please feel free to fork this repo and update the functions or add additional DOM based functions!

Installation

For NativeScript 3.0 and later type

tns plugin add nativescript-dom

To use in Nativescript 2.5 or earlier type:

tns plugin add nativescript-dom@1.1.0

Usage

To use the module you just require() it:

require("nativescript-dom");

Note: You do NOT need to keep a reference to it; and you only need to load it once. It will automatically attach its methods to all the proper classes in the NativeScript library, making it act as if they are built in.

Methods

`getElementById(id)`

`getElementsByClassName(className)`

`getElementsByTagName(tagName)`

These are globally available! Like their Web DOM counterparts; they return elements based on the critera.

`view.getElementById(id)`

`view.getElementsByClassName(className)`

`view.getElementsByTagName(tagName)`

Like their Web DOM counterparts; returns the children elements based on the critera.

exports.pageLoaded = function(args) {
  var page = args.object;
  var stackLayout = page.getElementsByTagName('StackLayout')[0];
  var button = stackLayout.getElementsByClassName('clickButton')[0];
  button.classList.toggle('hidden');
}

`view.runAgainstId(id, function(elem) { /* Do something with elem */ })`

`view.runAgainstClasses(className, function(elem) { /* Do something with elem */ })`

`view.runAgainstTagNames(tag, function(elem) { /* Do something with elem */ })`

This will automatically run your function passing it the elem that it matches; it will call your function multiple times once for each element that matches your selection.

exports.pageLoaded = function(args) {
  var page = args.object;
  page.runAgainstClasses('clickButton', function(elem) {  
      elem.classList.toggle('hidden');
  });
}

`view.classList.add(className, className, ...)`

Add a class to the view's class list at the end

someButton.classList.add('hidden');  // ClassList on this button will be "class1 class2 classx hidden"

`view.classList.insert(className, className, ...)`

Add a class to the view's class list at the front

someButton.classList.insert('hidden'); // ClassList on this button will be "hidden class1 class2 classx"

`view.classList.remove(className, className, ...)`

Removes a class from the view's class list

someButton.classList.remove('hidden'); // ClassList would then equal "class1 class2 class3"

`view.classList.toggle(className[, force])`

Toggles a class name if force = true, will force adding the class name only. (And won't remove it, but you won't have a second) if force = false, will force removing the class name only. (And won't add it)

`view.classList.item(index)`

Returns the class name at that location in the class list.

`view.classList.contains(className)`

Returns true or false if the class name exists in the class list.

if (someButton.classList.contains('hidden')) {
    someButton.classList.remove('hidden');
} else {
    someButton.classList.add('hidden');
 }
 
  // someButton.classList.toggle('hidden');    would be equivelent to the 5 lines above.

TypeScript Global Augmentation

This module ships a file, dom-global.d.ts, to enable intellisense and benefit from the TypeScript Typings add a reference in your references.d.ts file. Below is the snippet you can paste into the references.d.ts in the root of your app.

_{You may need to restart your IDE for it to resolve the added typings.}

/// <reference path="./node_modules/nativescript-dom/dom-global.d.ts" />
