复制粘贴下面的代码到控制台:
function render(node, splits) { splits.tag += '|----'; console.log(splits.tag + node.tagName); var children = node.children; if (!children) return; for (var i = 0, len = children.length; i < len; i++) { var child = children[i]; var _tag = splits.tag; render(child, splits); splits.tag = _tag; } } var splits = {tag:''} var start = (new Date()).getTime(); render(document.body, splits); var end = (new Date()).getTime(); console.log('Cost: ' + (end - start) + 'ms');
