Multiple execute js script

Question

I have a problem with js script.

I load subpage by ajax and append code to div.

$.ajax ({           
    type: "POST",
    url: "load/page/",
    dataType: "json",
    success : function(data) {
        $('.content').empty();
        $('.content').append(data);             
    },
    error : function(e) {
        console.log(e);             
    }           
});

Subpage contains appeal to js script:

<script src="//<?php echo $_SERVER['SERVER_NAME'].'/'.BASE_DIR; ?>/scripts/settings.js"></script>

Why when i execute ajax multiple times settings.js events are executing multiple too? I want to could execute ajax code multiple times but js scripts are executing only once.

why don't you put the code you have in settings.js in a function, which you load directly in the current page. Then you can call the function from your success handler. — trincot

because i have a lot of subpages and a lot of js scripts and I want to load only one script assigned to a subpage. — polak polkovski

I cannot reproduce the behaviour you describe: the script is executed every time it is appended. — trincot

In settings.js I have an event: $(document).on("click", "#update-button", function() { alert('click'); }); And after multiple execution ajax and click button i getting a lot of alerts — polak polkovski

That's going to turn into a real mess, but you can try removing document event handlers with .off() after you call .empty(). Another option would be to add a big if block around the code in the scripts and check if you've loaded it already (if they're all doing the same kind of $(document)-like stuff). — Jared Farrish

I replaced $(document) to $('.content') and add line $('.content').off(), now code is working great.
