What causes the truncation of the backslash in the string "videos\1_visualisation.mp4"?

Check out this example of AngularJS code I've created. The factory contains a list of video sources.

    var videoPlayer=angular.module('videoPlayer',[])

videoPlayer.controller("videoplayer",["$scope","videolist",function($scope,videolist)
{
    $scope.position=0;
    $scope.audiolength=videolist.sources.length;
    $scope.videosrc=videolist.sources[$scope.position];
    console.log($scope.videosrc)
}])

videoPlayer.factory('videolist',function()
{
    var videolist={};
    videolist.sources=[
    'videos\1_visualisation.mp4',
    'videos\2_visualisation.mp4',
    'videos\3_visualisation.mp4'
    ]
    return videolist;
})

Why is the backslash "\" being removed from the string?

$scope.videosrc=videolist.sources[$scope.position];

When accessing this line of code, it returns "videos1_visualisation.mp4". What could be causing this behavior?

Answer №1

In order to properly format the video sources, make sure to carefully escape the backslashes:

videolist.sources=[
    'videos\\1_animation.mp4',
    'videos\\2_animation.mp4',
    'videos\\3_animation.mp4'
    ]

Answer №2

The character \ is used to initiate an escape sequence. For example, in the case of \1, it represents the number 1 because it is not a special character. However, \n would indicate a new line.

To include the backslash itself as data within a string, you must use the escape sequence: \\

Answer №3

When it comes to backslashes, they have a special meaning as the beginning of "escape sequences" used for indicating special characters in coding. For instance, \n signifies a new line. If a number or letter does not match any recognized escape sequence, it will simply display the character itself. In this scenario, when you use \1, it appears as 1. To maintain the slash, you can either escape the slash on its own...

'videos\\1_visualisation.mp4'

...or if you only want to retain the file path...

'videos/1_visualisation.mp4'
