问题描述

我无法在if-else条件中使用jQuery toggleClass()。



我的HTML代码是:

 < ul> 
< li class =firstLevel>
< a href =#main_cat_01> MAIN CATEGORY#1< / a>
< ul class =dijete>
< li>
< a href =#subt_cat_01> SUB CATEGORY#1< / a>
< / li>
< / ul>
< / li>
< li class =firstLevel>
< a href =#main_cat_02> MAIN CATEGORY#2< / a>
< ul class =dijete>
< li>
< a href =#subt_cat_02_01> SUB CATEGORY#1< / a>
< / li>
< / ul>
< / li>
< / ul>

我的CSS代码是:

  ul.dijete {
display:none;
}

.vidimte {
display:block;
}

我的JavaScript代码是:

  var $ j = jQuery.noConflict(); 
$ j(function(){
$ j('li.firstLevel')click(function(){
if($ j(this).children(ul.dijete ).hasClass(vidimte)){
$ j(this).children(ul.dijete)。toggleClass('vidimte'); // visible
(this).find (ul.dijete)。prev(li.firstLevel a)。css({
background-image:'url(URL_TO_THE_IMAGE_OPEN)',
background-position:right center,
display:block,
background-repeat:no-repeat
});
} else {// else add image close并显示无
$ j(this).find('ul.vidimte')。prev(li.firstLevel a)。css({
background-image:'url(URL_TO_THE_IMAGE_CLOSE) ',
background-position:right center,
display:block,
background-repeat:no-repeat
} ;
}
});
});

我无法工作。



我必须使用on。('click)方法吗?

解决方案适用于我:

  var $ j = jQuery.noConflict(); 

$ j(function(){
$ j('li.firstLevel')。on('click' .closest(li)。children(ul.dijete)。length){
$ j(this).children(ul.dijete)。toggleClass('vidimte');


if($ j(this).children(ul.dijete)。hasClass(vidimte)){
$ j(this).find(ul.dijete ).prev(li.firstLevel a)。css({
background-image:'url(http://www.v-tac.hr/wp-content/themes/vtac/images/ story-customfilters / open.png)',
background-position:right center,
display:block,
background-repeat重复
});
} else {
$ j(this).find('ul.dijete')。prev(li.firstLevel a)。css $ bbackground-image:'url(http://www.v-tac.hr/wp-content/themes/vtac/images/stories/customfilters/closed.png)',
background-位置:右中心,
显示:块,
背景重复:无重复
}
}
}
});
});


I cannot get working jQuery toggleClass() within if-else condition.

My HTML code is:

<ul>
  <li class="firstLevel">
   <a href="#main_cat_01">MAIN CATEGORY #1</a>
     <ul class="dijete">
       <li>
          <a href="#subt_cat_01">SUB CATEGORY #1</a>
        </li>
     </ul>
   </li>
   <li class="firstLevel">
   <a href="#main_cat_02">MAIN CATEGORY #2</a>
     <ul class="dijete">
       <li>
          <a href="#subt_cat_02_01">SUB CATEGORY #1</a>
        </li>
     </ul>
   </li>
</ul>

My CSS code is:

ul.dijete {
    display: none;
}

.vidimte{
    display: block;
}

My JavaScript code is:

    var $j = jQuery.noConflict();
    $j(function() {
        $j('li.firstLevel').click(function(){
            if($j(this).children("ul.dijete").hasClass("vidimte")){
                $j(this).children("ul.dijete").toggleClass('vidimte'); //visible
                $j(this).find("ul.dijete").prev("li.firstLevel a").css({
                    "background-image":'url(URL_TO_THE_IMAGE_OPEN)',
                    "background-position":"right center",
                    "display":"block",
                    "background-repeat":"no-repeat"
                });
            }else{ // else add image close and display none
                $j(this).find('ul.vidimte').prev("li.firstLevel a").css({
                    "background-image":'url(URL_TO_THE_IMAGE_CLOSE)',
                    "background-position":"right center",
                    "display":"block",
                    "background-repeat":"no-repeat"
                });
            }
        });
    });

I cannot get this working.

Do I have to use on.('click) method for that?

Any ideas?

Thanks for help or any information!

解决方案

Got it! Thanks for sharing ideas!

Solution worked for me:

var $j = jQuery.noConflict();

$j(function() {
    $j('li.firstLevel').on('click', function() {
        if($j(this).closest("li").children("ul.dijete").length){
            $j(this).children("ul.dijete").toggleClass('vidimte');


            if($j(this).children("ul.dijete").hasClass("vidimte")){
                $j(this).find("ul.dijete").prev("li.firstLevel a").css({
                    "background-image":'url(http://www.v-tac.hr/wp-content/themes/vtac/images/stories/customfilters/open.png)',
                    "background-position":"right center",
                    "display":"block",
                    "background-repeat":"no-repeat"
                });
            }else{
                $j(this).find('ul.dijete').prev("li.firstLevel a").css({
                    "background-image":'url(http://www.v-tac.hr/wp-content/themes/vtac/images/stories/customfilters/closed.png)',
                    "background-position":"right center",
                    "display":"block",
                    "background-repeat":"no-repeat"
                });
            }
        }
    });
   });
