How do i print a string in html?

If just for example I do:

var = "Asd";

You should be using ng-bind-html directive.

Creates a binding that will innerHTML the result of evaluating the expression into the current element in a secure way.

Before using the ng-bind-html directive you must include the $sanitize service or it will throw an error.

Error: $sce:unsafe Require a safe/trusted value Attempting to use an unsafe value in a safe context.

Error: [$sce:unsafe] http://errors.angularjs.org/1.4.5/$sce/unsafe
    at Error (native)

The right way:

var myApp = angular.module('app', ['ngSanitize']);

myApp.controller('MyController', ['$scope', function($scope) {
  $scope.myHTML = 'Hello, World!';
}]);

https://docs.angularjs.org/api/ngSanitize

You can also try something like that:

    app.filter('to_trusted', ['$sce', function($sce) {
      return function(text) {
        return $sce.trustAsHtml(text);
      };
    }]);

and then, in view:

    ng-bind-html=" myHTML | to_trusted"

JavaScript Display Possibilities

JavaScript can "display" data in different ways:

• Writing into an HTML element, using innerHTML.
• Writing into the HTML output using document.write().
• Writing into an alert box, using window.alert().
• Writing into the browser console, using console.log().

Using innerHTML

To access an HTML element, JavaScript can use the document.getElementById(id) method.

The id attribute defines the HTML element. The innerHTML property defines the HTML content:

Example

My First Web Page

My First Paragraph

Changing the innerHTML property of an HTML element is a common way to display data in HTML.

Using document.write()

For testing purposes, it is convenient to use document.write():

Example

My First Web Page

My first paragraph.

Using document.write() after an HTML document is loaded, will delete all existing HTML:

Example

My First Web Page

My first paragraph.

The document.write() method should only be used for testing.

Using window.alert()

You can use an alert box to display data:

Example

My First Web Page

My first paragraph.

You can skip the window keyword.

In JavaScript, the window object is the global scope object, that means that variables, properties, and methods by default belong to the window object. This also means that specifying the window keyword is optional:

Example

My First Web Page

My first paragraph.

Using console.log()

For debugging purposes, you can call the console.log() method in the browser to display data.

You will learn more about debugging in a later chapter.

JavaScript Print

JavaScript does not have any print object or print methods.

You cannot access output devices from JavaScript.

The only exception is that you can call the window.print() method in the browser to print the content of the current window.

Example

Print this page
