javascript - Can't select a child -


i got html:

                <ul>                 <a href="#"><li>test</li></a>                 <a href="#"><li>test2</li></a>                 <a href="#" class="with-sub"><li>test3</li>                     <ul class="sub">                         <li><a href="#">sub1</a></li>                         <li><a href="#">sub2</a></li>                         <li><a href="#">sub3</a></li>                     </ul>                 </a>             </ul>

and jquery:

<script src="//code.jquery.com/jquery-2.1.4.min.js"></script> <script>     $( document ).ready(function() {         $(".sub").hide();     });     $(".with-sub").click(function() {         $(this).find(".sub").slidedown( "slow", function() {          });     }); </script>

when click on link "with-sub" class nothing happens.

you can change html , jquery following:

$(".with-sub").click(function() {    $(this).next("ul").slidedown();  });
.sub {    display: none;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <ul>    <a href="#">      <li>test</li>    </a>    <a href="#">      <li>test2</li>    </a>    <a href="#" class="with-sub">      <li>test3        <ul class="sub">          <li><a href="#">sub1</a>            </li>          <li><a href="#">sub2</a>            </li>          <li><a href="#">sub3</a>            </li>        </ul>      </li>    </a>  </ul>

as mention in comments html not correct. ul elements can contain 0 or more li elements, mixed ol , ul elements.

$(".with-sub").click(function() {    $(this).find("ul").toggle();  });
.sub {    display: none;  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <ul>    <li>      <a href="#">test</a>    </li>    <li>      <a href="#">test2</a>    </li>    <li class="with-sub"><a href="#">test3</a>      <ul class="sub">        <li>          <a href="#">sub1</a>        </li>        <li>          <a href="#">sub2</a>        </li>        <li>          <a href="#">sub3</a>        </li>      </ul>    </li>  </ul>

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
