我想更改页面的标题,这是在h1框中。 我知道我必须使用onclick函数,但我只使用了这个函数和按钮。当鼠标单击h1框时,如何更改页面标题?
这是我用JS的HTML:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Practice</title>
<link rel='stylesheet' href='main.css'/>
</head>
<script>
function changeTitle() {
var title = prompt("Change the title:");
}
</script>
<body>
<div>
<h1 onclick="changeTitle()">To-Do List</h1>
<ul class='todo-list'>
<li class='todo-item'>4L 2% Milk
<span class='remove'></span></li>
<li class='todo-item'>Butter, Unsalted
<span class='remove'></span></li>
<li class='todo-item'>Dozen Eggs
<span class='remove'></span></li>
<li class='todo-item'>Walk the dog
<span class='remove'></span></li>
<li class='todo-item'>Cut the lawn
<span class='remove'></span></li>
<li class='todo-item'>Laundry
<span class='remove'></span></li>
<li class='todo-new'>
<input id='new-item-text' type='text'/>
<a id='add-item' href='#'>+</a>
</li>
</ul>
</div>
<script src='main.js'></script>
</body>
</html>

您已关闭,只需将innerText
设置为您从prompt()
返回的标题即可。访问h1
的最简单方法是将其传递到changeTitle()
。点击后,它会显示为this
,我们可以在功能中使用它。
function changeTitle(element) {
var title = prompt("Pick a new title:");
element.innerText = title;
}
&#13;
<h1 onclick="changeTitle(this)">First Title</h1>
&#13;

你可以试试这个
<h1 id="myTitle">To-Do List</h1>
然后..
function changeTitle() {
var title = prompt("Change the title:");
if(title){
this.innerText = title
}
}
var el = document.getElementById("myTitle");
el.addEventListener("click", changeTitle);
