範例
以下方函式為例:
function divide(x, y) {
if (y === 0) {
throw "Division by zero";
}
return x/y;
}
如果
除數 y 為零:
var x = document.getElementById('x').value;
var y = document.getElementById('y').value;
try {
var r = divide(x, y);
} catch(err) {
gtag('event', 'exception', {
'description': err,
'fatal': false
});
}
