How to check true or false = extended area?

I have the following list in bootstrap

<i class="fa fa-plus rgh-i" data-toggle="collapse" data-target="#field-1"></i>
<i class="fa fa-plus rgh-i" data-toggle="collapse" data-target="#field-2"></i>
<i class="fa fa-plus rgh-i" data-toggle="collapse" data-target="#field-3"></i>

I use bootstrap to switch the div.

Each html element ihas aria-expanded="true"when I want to show my divs and aria-expanded="false"when I want to hide my div.

I want to check if there are already elements that are aria-expanded="true".. and are there nearby to hide the previous open.

$( "i" ).on( "click", function() {
        if(There are elements of that property aria-expanded="true")
       {
        hide previous item before you open the current one
       }else{
        //something
       }
});

I tried to make a jsdfiddle example, but unfortunately we did it ... I hope you understand what I want to do.

Basically ... I briefly before hiding the previous item to display the next and not be able to open more than one item.

Thanks in advance!

:

,

var areaexpandedtrue = $('[aria-expanded=true]');
if(areaexpandedtrue.length){
   areaexpandedtrue.hide();
}
0
if(this.attr('aria-expanded') === "true"){
     // hide previous item before you open the current one
}
0

you can also get the value first and then compare.

var value = $('#aria-expanded').val(); // jQuery func.

if (value =='true'){
//do some stuff
}
else{
//do some stuff
}
