remove appended script javascript

rated 0 times [ 90] [ 2] / answers: 1 / hits: 55257 / 13 Years ago, wed, february 22, 2012, 12:00:00

how can I remove my appended script because it causes some problems in my app.

This is my code to get my script

var nowDate = new Date().getTime();

var url = val.redirect_uri + notify.js?nocache= + nowDate + &callback=dummy;

var script = document.createElement('script');

script.src = url;

document.body.appendChild(script);

Then I have an auto load function, that causes to create another element script.

I want to get rid of the previous element that was appended before another element is added.

I did some more tests, and before you'll get a correct answer to your question (hope there is a one) you can try this:

<button onclick=foo()>ShowHTML</button>

<script>

(function foo(){

    var b=function moo(){

        var c=document.getElementsByTagName('script');

        alert(document.body.innerHTML);

        c[0].parentElement.removeChild(c[0]);

        alert(document.body.innerHTML);

    }

    var a=setTimeout(b,1000);

    b=null;

})();

foo=null;

</script>

This is just a test code, but it contains an idea, how you possible could solve the problem. It removes <sript> from the DOM, and the last line destroys all functionality of the script.

(The code also has a little detail, which shows, that setTimeout will do eval(), no matter how it is argumented...?)
