tchmi_equal

[ Function ]

function tchmi_equal(value1: any, value2: any, bTypeSafe: boolean = true): boolean;

Checks whether two variables are equal.

In JavaScript, simple data types (such as Booleans or numbers) are copied when used (by value). However, if a data type is complex, a reference is used (by reference), so that manipulation of the supposed copy also changes the original value.

A comparison for equality is not trivial with values such as SolidColor, for example since the simple === operator checks the references but not the content.

The function tchmi_equal can be used instead.

Sample - JavaScript

var myColor = {color: 'red'};
var myColor2 = {color: 'red'};
TcHmi.Log.debug(
    'JS compare: ' + (myColor === myColor2) + 
    ' tchmi_equal: ' + tchmi_equal(myColor, myColor2)); // JS compare: false tchmi_equal: true
