I have to loop through a ol and then get each of the li and then remove the text and add "<a" element to it. Following is the html that is rendered:
<ol class="progress">
<li class="list-group-item text-muted list-group-item-success active">
General Information<span>1</span>
</li>
</ol>
I want to remove all the classes except "active" and then wrap the text with General Information Like below
<ol class="progress">
<li class="active">
<a href="#">General Information<span> 1</span></a>
</li>
</ol>
I have tried to loop through the Ol using the script below but it seems to not find anything
$('ol.progress').each(function (i, li) {
var listItem = li;
var lm = $(li).text();
console.log(lm);
});
With vanilla js:
document
.querySelectorAll('ol.progress > *') // all children of <ol> with class .progress
.foreach(elem => {
elem.className = 'active'
elem.innerHTML = `<a href="#">${elem.innerHTML}</a>`
})
I see you are using JQuery - so let's stick to this.
You are looping over the ol but you want to loop over the ol's lis.
So replace
$('ol.progress').each....
by
$('ol.progress li').each....
You can remove all classes with the .removeClass() without any parameters.
But as you want to preserve the active-class you have to preserve this attribute - in my version of the code (see below) I will use a variable for this.
In addition you want to replace the HTML-part and not the text-part - so your snippet would read
$('ol.progress li').each(function () {
var is_active = false;
is_active = $(this).hasClass('active');
$(this).removeClass();
if(is_active){
$(this).addClass('active');
}
var newcontent = '<a href="#">' + $(this).html() + "</a>";
$(this).html(newcontent);
});
With jquery, as you can see, I check if the element has a class, then I remove all the classes and add active if it had it.
$('ol.progress li').each(function(i, li) {
var listItem = li;
if ($(li).hasClass('active')) {
$(li).removeAttr('class');
$(li).addClass('active');
} else {
$(li).removeAttr('class');
}
});.active {
color: red;

<ol class="progress">
<li class="list-group-item text-muted list-group-item-success active">
General Information<span>1</span>
</li>
<li class="list-group-item text-muted list-group-item-success">
General Information<span>2</span>
</li>
<li class="list-group-item text-muted list-group-item-success">
General Information<span>3</span>
</li>
</ol>In your code you forgot li into selector so $('ol.progress li') instead of $('ol.progress')
