Return from jQuery function

Hello, I'm picking up on something very simple. I have a function in jQuery that checks if there is any open modal on the page. For this it checks the class of <body> and returns 1 if it has modal open and 0 if it does not.

So far so good. If I give a console.log inside ifs it works normally. But, now comes the "problem."

I tried several ways to use the return in my script php but I can not. I just want to get the return, and check if it's equal to 1, if it's got modal open, if it's 0 it does not have it.

Could you help me?

function:

function verifyModals(){
if ($("body").hasClass("modal-open")) {
    console.log('modal aberto');
    return 1;
}else{
    console.log('modal FECHADO');
    return 0;
}

}

In my script php , how do I get the return? a echo "<script>verifyModals();</script>"; would no longer solve?

Thank you in advance

Lipearu,

If I understand correctly, you want to get the return of this jQuery function and use it in your PHP script.

But this is not possible, quite simply what happens is:

The user makes a request for your page

Your server receives the request interprets which page should be returned.

Your PHP code from that page will be interpreted and will return the HTML page.

The server takes that page and returns it to the user.

From that moment on, your jQuery will start running and your page will not run again.

The point is PHP is interpreted by the server, jQuery is interpreted by the browser. So if you want to make your return interpreted by some PHP, you should make a request and get your return. I would advise you to use Ajax for this.
