I have it disabled already, and I can enable it again. I used:

document.ontouchmove = function(e){
             e.preventDefault();
}

In the document.ready(); to disable it.

And I used this to enable it.

function doTouchMove(state) {
    document.ontouchmove = function(e){
      return state;
    }
}

I have it so when a user double clicks on an element, the doTouchMove is called. But how do I make it disabled again?

Thanks

You could create a toggle instead, where your doTouchMove() function switches between false and true every time it's called:

(function () { // Set up a closure so we don't pollute the global scope
    var state = false;
    function doTouchMove() {
        state = !state;
    }
    document.ontouchmove = function(e){
        return state;
    }
    document.getElementById("myDoubleClickElement").ondblclick = doTouchMove;
})();

Now, every time you double-click #myDoubleClickElement, it will toggle the state variable's value between false and true, effectively disabling on the even clicks and enabling on the odd clicks.

Im the same user who asked this question... but I cleared my history & everything so I can't pick an answer or anything!

But what I did to fix it was put this

document.ontouchmove = function(e){
             e.preventDefault();
}

Into its own function, just as the doTouchMove() was. Then when I wanted it to stop moving again i would just call the name of that preventDefault function.

I don't know why it makes a difference but it works! :)
