js选择div中的a标签

// 假设div的ID是'myDiv'
var div = document.getElementById('myDiv');
var links = div.getElementsByTagName('a');

for (var i = 0; i < links.length; i++) {
    console.log(links[i].href); // 打印每个a标签的href属性
}

// 获取id为'myDiv'的div中的所有a标签
var links = document.querySelectorAll('#myDiv a');

links.forEach(function(link) {
    console.log(link.href); // 打印每个a标签的href属性
});

// 假设div的类名是'myClass'
var divs = document.getElementsByClassName('myClass');
for (var i = 0; i < divs.length; i++) {
    var links = divs[i].getElementsByTagName('a');
    for (var j = 0; j < links.length; j++) {
        console.log(links[j].href);
    }
}

window.onload = function() {
    var links = document.querySelectorAll('#myDiv a');
    // 处理links
};
