Testing JavaScript Functions
Introduction
This guide demonstrates how to trigger different functions based on a CSS class applied to the <body> tag, using a dynamic testId variable. This version includes examples for handling up to four different variations.
Code Implementation
Use the following code to check for specific body classes and trigger functions accordingly. Just replace the testId with the ID of your test. You should also rename functionA() and so on to your own functions.
// Define the test ID
var testId = 1595; // Replace with your actual test ID
// Wait for the document to be ready
jQuery(document).ready(function() {
// Check if body has specific class and run corresponding function
if (jQuery('body').hasClass('test-css-' + testId + '-1')) {
functionA();
} else if (jQuery('body').hasClass('test-css-' + testId + '-2')) {
functionB();
} else if (jQuery('body').hasClass('test-css-' + testId + '-3')) {
functionC();
} else if (jQuery('body').hasClass('test-css-' + testId + '-4')) {
functionD();
}
});
// Define functionA
function functionA() {
console.log('Function A triggered for test-css-' + testId + '-1');
// Add your function A code here
}
// Define functionB
function functionB() {
console.log('Function B triggered for test-css-' + testId + '-2');
// Add your function B code here
}
// Define functionC
function functionC() {
console.log('Function C triggered for test-css-' + testId + '-3');
// Add your function C code here
}
// Define functionD
function functionD() {
console.log('Function D triggered for test-css-' + testId + '-4');
// Add your function D code here
}
Explanation
- Dynamic Test ID: Define the
testIdvariable at the top of the code. - Check Body Class: The code checks if the <body> has a class with the format
test-css-[testId]-1,test-css-[testId]-2,test-css-[testId]-3, ortest-css-[testId]-4. - Trigger Functions: Each body class triggers a corresponding function:
test-css-[testId]-1triggersfunctionA().test-css-[testId]-2triggersfunctionB().test-css-[testId]-3triggersfunctionC().test-css-[testId]-4triggersfunctionD().
This setup provides an easy way to manage different functions based on dynamically assigned body classes, making it convenient for split testing and handling multiple variations.
