HTMLElement.title

HTMLElement.title 属性表示元素的 title。当鼠标移到节点上时,会以“工具提示”(tool tip)的弹出形式显示该属性的属性值文本。

如果一个节点没有 title 属性(attribute),默认继承其父节点的相应属性,父节点可能是从父节点的父节点继承,依此类推。

语法

var string = element.title;
element.title = string;

例子

const link = document.createElement('a');
link.innerText = '葡萄';
link.href = 'https://en.wikipedia.org/wiki/Grape';
link.title = '维基百科上对葡萄的描述';
