如何使用 jQuery 定位名称属性

Question

So...

I have this Icon that I am using, from ion icons. I want to add a jquery that when the user clicks the icon it changes to another one. But the issue is, it uses the attribute name to target the icon.

<a class="mobile-nav-icon js--nav-icon"><ion-icon name="menu-outline"></ion-icon></a>

I want to change the name to the other type of icon

<a class="mobile-nav-icon js--nav-icon"><ion-icon name="close-outline"></ion-icon></a>

How can I target the name attribute? I tried the bellow, following the hasClass, addClass, removeClass logic but didnt work.

$('.js--nav-icon').click(function(){
var nav = $('.js--main-nav');
var icon = $('.js--nav-icon ion-icon');

nav.slideToggle(200);
if (icon.hasName('menu-outline')){
  icon.addName('close-outline');
  icon.removeName('menu-outline');
} else {
  icon.addName('menu-outline');
  icon.removeName('close-outline');
}});

Im quite new at Web Dev.

Answer 1

You can do:

if (icon.attr('name') === 'menu-outline'){
    icon.attr('name', 'close-outline');

Answer 2

You can use the .attr(attrName, value) or .attr(attrName, function) :

 $('.js--nav-icon').click(function(){ var nav = $('.js--main-nav'); var icon = $('.js--nav-icon ion-icon'); nav.slideToggle(200); icon.attr('name', icon.attr('name') === 'menu-outline'? 'close-outline': 'menu-outline'); //Remove this..... just for testing console.log( icon[0] ); });

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <a class="mobile-nav-icon js--nav-icon"><ion-icon name="menu-outline">[ICON]</ion-icon></a>

Answer 3

You can use

if($('.js--nav-icon ion-icon').attr('name') === 'menu-outline') {
 $('.js--nav-icon ion-icon').attr('name', 'close-outline');
}
