Jquery href click - how can I fire up an event?
提问by user1965451
I have this anchor and on click I would like to popup something. This href is within a page that has other hrefs.
我有这个锚点，点击我想弹出一些东西。此 href 位于具有其他 href 的页面内。
<a class="sign_new" href="#sign_up">Sign up</a>
jQuery:
jQuery：
$(document).ready(function(){
$('a[href = "sign_up"]').click(function(){
alert('Sign new href executed.');
});
});
The above code does not fire up.
上面的代码没有启动。

It doesn't because the href value is not sign_up.It is #sign_up. Try like below,
You need to add "#" to indicate the id of the href value.
不是因为 href 值不是sign_up.It 是#sign_up. 尝试如下，您需要添加“#”来指示href值的id。
$('a[href="#sign_up"]').click(function(){
alert('Sign new href executed.');
});

If you own the HTML code then it might be wise to assign an id to this href. Then your code would look like this:
如果您拥有 HTML 代码，那么为这个 href 分配一个 id 可能是明智的。然后你的代码看起来像这样：
<a id="sign_up" class="sign_new">Sign up</a>
And jQuery:
和 jQuery：
$(document).ready(function(){
$('#sign_up').click(function(){
alert('Sign new href executed.');
});
});
If you do not own the HTML then you'd need to change $('#sign_up') to $('a.sign_new'). You might also fire event.stopPropagation() if you have a href in anchor and do not want it handled (AFAIR return false might work as well).
如果您不拥有 HTML，则需要将 $('#sign_up') 更改为 $('a.sign_new')。如果您在锚点中有一个 href 并且不想处理它，您也可能会触发 event.stopPropagation() （AFAIR return false 也可能有效）。
$(document).ready(function(){
$('#sign_up').click(function(event){
alert('Sign new href executed.');
event.stopPropagation();
});
});

Try:
尝试：
$(document).ready(function(){
$('a .sign_new').click(function(){
alert('Sign new href executed.');
});
});
You've mixed up the classand hrefnames / selector type.
您混淆了class和href名称/选择器类型。

You are binding the clickevent to anchors with an hrefattribute with value sign_new.
您将click事件绑定到带有值的href属性的锚点sign_new。
Either bind anchors with class sign_newor bind anchors with href value #sign_up. I would prefer the former.
要么用 classsign_new绑定锚点，要么用 href 值绑定锚点#sign_up。我更喜欢前者。
