问题描述
如果存在CSS类,我将尝试着重于页面中的特定ID.但是我拥有的代码不起作用,我不确定为什么吗?
I am trying to set focus on a certain ID in the page if a CSS class is present. However the code that I have doesn't work and I am not certain why?
$(document).ready(function() {
if ($('body').hasClass('message')) {
$('#maincontent').focus();
}
});
HTML: 页面中用于设置焦点的锚点:
HTML: The Anchor in the page to set focus:
<a name="maincontent" tabindex="-1" id="maincontent"/>
如果该div存在于页面中:
If this div is present in page:
<div class="message success"><p><span class="glyphicon glyphicon-ok-sign" aria-hidden="true"></span> Your submission has been received.</p></div>
推荐答案
将其更改为:
$(document).ready(function() {
if ($('body .message').length) {
$('#maincontent').focus();
}
});
正文在HTML中没有类消息.
The body doesn't have class message in your HTML.
