focus（）不适用于锚链接

Question

<a id="news_click" href="#news"> <span style="color:#B2B2B2" class="radius secondary label">Do you want fresh news and feeds?</span></a>

<div class="large-5 columns">
    <div class="row collapse">
        <div class="small-12 columns">
            <form id="email_form" data-validate="parsley" data-trigger="focusin focusout">
                </br>
                <input id="email" type="text" placeholder="Email" class="hg" name="email" data-notblank="true" data-type="email">
            </form>
        </div>
    </div>
</div>

<div class="bottom_blue" id="news"></div>

---

$('#news_click').click(function () {
    $('form#email_form input#email.hg').focus();
});

The focus event only works if i remove the <div class="bottom_blue" id="news"></div . This is not an option since this is an anchor link.

Any idea? Probably the problem is that js is executed before the anchor.

EDIT: Apparently this works in chrome, not in FF.

Answer 1

Essentially you need to account for the click event and focus as a race condition in Firefox. Use either:

$('#news_click').click(function (e) {
    e.preventDefault();
    $('#email').focus();
});

or

$('#news_click').click(function (e) {
    setTimeout(function(){$('#email').focus();},10);
});

Answer 2

You forgot an angle bracket at the end of <div class="bottom_blue" id="news"></div ...

Demo here

Use this instead:

<div class="bottom_blue" id="news"></div>

Also, try changing this:

$('form#email_form input#email.hg').focus();

To this:

$('#email').focus();

There can only be one element with the same id anyway, so it makes no difference how specific you are.

EDIT: Firefox seems to visit the href after the email box is focused... You can either use preventDefault() as in j08691's answer, or take the href attribute off the link (see the updated fiddle ).
