如何用一段javascript代码打开两个或多个弹出窗口

// 打开第一个弹出窗口
var popup1 = window.open('https://example.com/page1', 'Popup1', 'width=600,height=400');

// 打开第二个弹出窗口
var popup2 = window.open('https://example.com/page2', 'Popup2', 'width=600,height=400');

// 检查窗口是否成功打开
if (popup1 && popup2) {
    console.log('两个弹出窗口都已成功打开');
} else {
    console.log('无法打开所有弹出窗口');
}

document.getElementById('openPopupsButton').addEventListener('click', function() {
    var popup1 = window.open('https://example.com/page1', 'Popup1', 'width=600,height=400');
    var popup2 = window.open('https://example.com/page2', 'Popup2', 'width=600,height=400');
});

if (popup1) {
    popup1.focus();
}
if (popup2) {
    popup2.focus();
}
