JavaScript - detect Apple Safari web browser
3
points
In this short article, we would like to show how using JavaScript, detect Apple Safari web browser on Apple devices.
Quick solution:
// ONLINE-RUNNER:browser;
const appleExpression = /Apple/i;
const safariExpression = /Safari/i;
const isAppleSafari = () => {
return appleExpression.test(navigator.vendor) &&
safariExpression.test(navigator.userAgent);
};
// Usage example:
if (isAppleSafari()) {
console.log('You are on Apple Safari web browser.');
} else {
console.log('You are not on Apple Safari web browser.');
}
Warning:
User-Agentcan be changed by advanced user that makes lead to some errors - if it may be your case, check alternative solution too.
Alternative solution
In this solution, we test only user agent to detect web browser.
// ONLINE-RUNNER:browser;
const platformExpression = /Mac|iPhone|iPod|iPad/i;
const rejectedExpression = /Chrome|Android|CriOS|FxiOS|EdgiOS/i;
const expectedExpression = /Safari/i;
const isAppleSafari = () => {
const agent = navigator.userAgent;
if (rejectedExpression.test(agent)) {
return false;
}
return platformExpression.test(agent) && expectedExpression.test(agent);
};
// Usage example:
if (isAppleSafari()) {
console.log('You are on Apple Safari web browser.');
} else {
console.log('You are not on Apple Safari web browser.');
}
Warning:
Apple Safar web browser was released last time on Windows in 2012, that makes why we do not consider other platforms in the above logic.
Example test
// ONLINE-RUNNER:browser;
const platformExpression = /Mac|iPhone|iPod|iPad/i;
const rejectedExpression = /Chrome|Android|CriOS|FxiOS|EdgiOS/i;
const expectedExpression = /Safari/i;
function isAppleSafari(agent) {
if (rejectedExpression.test(agent)) {
return false;
}
return platformExpression.test(agent) && expectedExpression.test(agent);
}
// Testing data:
const agents = [
