jQuery在选项卡式内容UL LI列表内嵌套LI元素

Question

Im using tabbed content on my page ( SEE MY FIDDLE )

Now the tabbed content makes use of <ul><li> elements to display the different tabs. Inside one of these tabs I would like to add a <ul><li> list however the list is not getting displayed correctly I suspect because:

1. The jquery is effecting it
2. It is nested inside another li elements

Any idea how I can fix this?

please look at fiddle to fully understand my question

Answer 1

The styles affecting the li's are defined as affecting all the li's inside the #tabs container. You can add the direct descendant selector (>) to the css styles fot the tabbed menu so that these styles don't affect other li's

 ul#tabs {
     list-style-type: none;
     padding: 0;
     text-align: center;
 }
 ul#tabs>li {
     display: inline-block;
     background-color: #32c896;
     border-bottom: solid 5px #238b68;
     padding: 5px 20px;
     margin-bottom: 4px;
     color: #fff;
     cursor: pointer;
 }
 ul#tabs>li:hover {
     background-color: #238b68;
 }
 ul#tabs>li.active {
     background-color: #238b68;
 }
 ul#tab {
     list-style-type: none;
     margin: 0;
     padding: 0;
 }
 ul#tab>li {
     display: none;
 }
 ul#tab>li.active {
     display: block;
 }

Answer 2

You can use the > , child selector to refine the selectors to match only the <li> elements immediately under <ul id="tab"> :

 ul#tab > li {
     display: none;
 }
 ul#tab > li.active {
     display: block;
 }

 $("ul#tab > li:nth-child(" + nthChild + ")").addClass("active");

Without > , the selectors will match any <li> descendant of <ul id="tab"> :

<ul id="tab">
    <li><!-- ... --></li>
    <li>
        <!-- ... -->
            <li>one</li>
            <li>Two</li>
            <li>THree</li>
        <!-- ... -->
    </li>
    <li><!-- ... --></li>
</ul>

ul#tab li:nth-child(1) , for example, matches both of these as the first-child of their respective parents:

<li>one</li>

<li>
    <p>HI There Enter personal Info</p>
</li>
