1、复制控制台输出的对象
获取对象名称,然后输入copy函数,对象名称作为函数参数,然后回车,再粘贴。

2、一键展开所有DOM元素
鼠标光标放在箭头处,按住option,然后点击鼠标,这样div等全都展开了。

或者右键选择expand recursively:

3、网络请求重复请求一次
network-->Fetch/XHR-->选择要请求的网络-->右键-->选择Reply XHR

4、查看页面布局
添加书签-->名称随便起一个,网址填写:
javascript: (function() {
var elements = document.body.getElementsByTagName('*');
var items = [];
for (var i = 0; i < elements.length; i++) {
if (elements[i].innerHTML.indexOf('html * { outline: 1px solid red }') != -1) {
items.push(elements[i]);
}
}
if (items.length > 0) {
for (var i = 0; i < items.length; i++) {
items[i].innerHTML = '';
}
} else {
document.body.innerHTML +=
'<style>html * { outline: 1px solid red }</style>';
}
})();
保存书签,随便打开一个网页,点击书签,会显示网页结构:

5、修改页面内容

- 双击光标出的内容
- 右键选择Edit text或者Edit as Html

6、console输出dom
光标选中dom,切换到console,输入$0,即可打印
