当我使用jQuery按下“Go”按钮时,我试图从文本区域替换页面标题。我还没有成功。我尝试过replaceWith(),但是没有用,所以我尝试了这个:
的test.html:
<html>
<head>
<title>Test</title
<script src="jQuery.min.js"></script>
<script src="go.js"></script>
<link id="si" rel="shortcut icon" media="all" type="image/x-icon" href="http://www.google.com/favicon.ico" />
<!-- This was for trying to change the icon (also unsuccessful) -->
<link id="i" rel="icon" media="all" type="image/vnd.microsoft.icon" href="http://www.google.com/favicon.ico" />
</head>
<body>
<textarea id="title">Type the new title.>;/textarea>
<!-- Put the favicon switcher here -->
<button onclick="go()">Go</button>
<br />
</body>
</html>`
go.js:
$(function go() {
var title = document.getElementById('title').value();
document.title = title;
});

使用此go功能:
function go() {
var title = $('#title').val();
$('title').text(title);
};

没有jQuery:
<html>
<head>
<title></title>
</head>
<body>
<input type="text" onkeyup="updateTitle()" id="tinput">
<script>
var title = document.getElementsByTagName('title');
title = title[0];
var titleInput = document.getElementById('tinput');
function updateTitle() {
title.innerHTML = titleInput.value;
}
</script>
</body>
</html>

哦,您正在寻找jQuery解决方案。我会保留答案,也许其他人会使用它:)

你也可以试试这个:
go = function () {
var title = document.getElementById("title").value;
alert(title);
document.title = title;
}
