我正在开发 chrome 扩展。当用户单击按钮时,我想将输入值(用户名)更改为一些文本。但我的解决方案不起作用。需要建议。我的代码如下所示:
<!DOCTYPE html>
<html>
<head>
<META http-equiv=content-type content=text/html;charset=utf8>
<META http-equiv=content-type content=text/html;charset=windows-1254>
<META http-equiv=content-type content=text/html;charset=x-mac-turkish>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<title></title>
<script>
$('#target').submit(function() {
alert('something');
return false;
$('#UserName').value('test');
});
</script>
</head>
<body>
<form id="target">
<table>
<tr>
<td>UserName:</td>
<td>
<input type="text" id="UserName" size="20" />
</td>
</tr>
<tr>
<td>Password:</td>
<td>
<input type="password" id="Password" />
</td>
</tr>
<tr>
<td></td>
<td><input type="button" value="Login" id="Login" /></td>
</tr>
</table>
</form>
</body>
</html>
