2、JavaScript 详说事件机制之冒泡、捕获、传播、委托

<!DOCTYPE html>

    <body>
    <div id="btn">点击</div>
    <div id="parent">
        父元素
        <div id="child">
            子元素
        </div>
    </div>
    
    <script type="text/javascript">
        var btn = document.getElementById("btn");
        btn.addEventListener('click', function (evt) {
            console.log('dmji');
            window.open('http://www.baidu.com','_self')
        });
        var parent = document.getElementById("parent");
        var child = document.getElementById("child");
    
        // document.body.addEventListener("click",function(e){
        //     console.log("click-body");

        //
        // parent.addEventListener("click",function(e){
        //     console.log("click-parent");
        // },false);
        //
        // //新增事件捕获事件代码
        // parent.addEventListener("click",function(e){
        //     console.log("click-parent--事件捕获");
        // },true);
        //
        // child.addEventListener("click",function(e){
        //     console.log("click-child");
        //     e.stopPropagation();
        // },false);
        // parent.onclick = function(e){
        //     if(e.target.id == "child"){
        //         console.log("您点击了child元素")
        //     }
        // }
    
        parent.addEventListener("click",function(e){
            const target = e.target
            if(target.id==='child'){
                console.log("您点击了child元素")

3、BOM（浏览器对象模型）

1>在原来的窗体中直接跳转用  
window.location.href="你所要跳转的页面";  
2>在新窗体中打开页面用：  
window.open('你所要跳转的页面');

4、JavaScrip中的Window.location.href和Window.open（）方法

window.location.href = 'http://www.baidu.com';

window.open('http://www.baidu.com');
