jQuery if href attr

I have t开发者_运维百科his html structure:

<ul class="tabs">
            <li><a href="#tab1"><h3>Sound</h3><img class="servicesIcon" src="img/micro.png"></img></a></li>
            <li><a href="#tab2"><h3>Lighting</h3><img class="servicesIcon" src="img/light.png"></img></a></li>
            <li><a href="#tab3"><h3>Staging</h3><img class="servicesIcon" src="img/barstool.png"></img></a></li>
            <li><a href="#tab4"><h3>Sales</h3><img class="servicesIcon" src="img/info.png"></img></a></li>
            <li><a href="http://www.example.co.uk/" target="_BLANK"><h3>Hire Guide</h3><img class="servicesIcon" src="img/info.png"></img></a></li>
        </ul>

and this jQuery:

$("ul.tabs li").click(function() {



                $("ul.tabs li").removeClass("active"); //Remove any "active" class
                $(this).addClass("active"); //Add "active" class to selected tab
                $(".tab_content").hide(); //Hide all tab content

                var activeTab = $(this).find("a").attr("href"); //Find the href attribute value to identify the active tab + content
                $(activeTab).fadeIn(); //Fade in the active ID content
                return false;
            });

But what i want to do is if the 'li' is clicked that doesn't have a href of #tab then it just returns true and follows the link as normal?

If you're saying that you don't want the handler to fire for the link without a #tab, then just don't assign the handler to it in the first place.

$("ul.tabs li").slice(0,-1).click(function() {
    // and so on

This will assign the click handler to all but the last one.

You could also do something more like this:

$("ul.tabs li:not(:last)").click(function() {
    // and so on

or:

$("ul.tabs li:not(:last-child)").click(function() {
    // and so on

To complete patrick dw's list, the generic version:

$('ul.tabs li:has(a[href^=#tab])').click(function() {
});

This will only effect li nodes which contain an anchor with a href that begins with #tab

If you have multiple external links you could use this:

var activeTab = $(this).find("a").attr("href");
if(activeTab.substr(0,1) == '#'){ //if link starts with # - do fade, else treat as actual link.
  $(activeTab).fadeIn();
  return false;
}
else
  return true;

$("ul.tabs li").click(function() {

    $("ul.tabs li").removeClass("active");
    $(this).addClass("active");

    $(".tab_content").hide();

    var takE = $(this).attr('href'); //select the href from clicked element
    var swap = takE.replace('#',''); //strip it, if #tab1 clicked result = 'tab1'
    $('#' + swap).show(); // this will show clicked element like id="tab1"

});

You can use attribute selectors to bind only to the links whose target starts with the string #tab:

$("ul.tabs a[href^=#tab]").click(function() {
    //...
});   

This would require you to modify the contents of your function slightly, because the context will have changed (from the li to the a).

Update your HTML as follows as the syntax is a little off :

1. You cannot have block elements inside inline elements.
2. <img></img> should be <img /> and have an alt attribute even if it is blank.

3. You can change your unordered list to an ordered list to let a user know how many tabs there are. (You are already marking up the href="tab1...tab2" so there is already an order to it)

   <ol class="tabs"> <li><h3><a href="#tab1">Sound<img alt="" class="servicesIcon" src="img/micro.png" /></a></h3></li> </ol>
