I'm writing a chrome extension, and I want to be able to disable JavaScript based on a condition. So the page loads, a bunch of JavaScript runs, and if my condition is met then I'd like to disable all JavaScript. Is that possible? We would need to terminate/stop the currently running scripts.
I don't care too much if my chrome extension's script is stopped/disabled as well. But it would be nice if I could keep just that javascript running.
Thanks
One hacky way to achieve this is by defining a object with all your functions in it and then deleting said object from memory like so.
var obj = {
first : function(){
return "1";
},
second : function(){
return "2";
}
};
console.log( obj.first() ); // "1"
console.log( obj.second() ); // "2"
delete obj; // will remove from memory thus disabling it.
//will now return error
console.log( obj.first() );
console.log( obj.second() );
Please note though if you declare a var outside the var obj scope that points to obj it will still exist even after using delete.
var obj = {
first : function(){
return "1";
},
second : function(){
return "2";
}
};
var stillAlive = obj;
delete obj; // will it remove from memory?
//Ha gotcha i'm still here.
console.log( stillAlive.first() );
console.log( stillAlive.second() );
