如何使用jQuery选择并单击

Question

<div id="subNav-Requests" class="suit-sub-nav" style="">
  <ul class="page-container">
    <li>
    <a class="navLink0" href="/MyApp/reporting/list/data.do">
        <span>Report Data</span>
    </a>
    </li>
  </ul>
</div>

I have a code like this. I am trying to simulate a click on 'Report Data' . What I am trying is

var nav = 'div#subNav-' + mainNavId; //results in 'div#subNav-Requests'
$(nav+' a.navLink0').trigger('click'); 

No errors, nothing happens. I also tried this

$('a.navLink0').trigger('click'); 

to the same effect. I have to select the subNav-Requests because there are many more like that, for Eg subNav-Reports , subNav-Allergies etc. with the same structure but with many navLinks inside.

Answer 1

Calling click on an element just executes any event handlers attached to the element. It will not send the browser to the href of an a tag. To do that the best I can think of is:

var href = $('a.navLink0').attr('href');
window.location.href = href;

Does that meet your need?

Answer 2

请尝试$('a.navLink0', nav).click();

As far as i know you cant simulate an actual click on the link, what you are doing is simply triggering a click event, but that isnt enough.

You could set a listener for the event by

$('a.navLink0').click(function() {
    window.location = $(this).attr("href");
});

and then triggering the click event, but why are you doing this? wouldnt a redirect fit your purpose better?

window.location = $('a.navLink0').attr("href");
