Prevent function from executing or removing anonymous event listeners

Question

I'm creating a Chrome extension for a website that has no open API, so I'm stuck reading Closure Compiled spaghetti code for a long time. I've made a lot of progress but I seem to be stuck. On the page's onload, this function executes:

function comments_initReply(){
    var b=$("#ajax_comm div.com");
    for(var a=0;a<b.length;a++){var d=$(b[a]);
    var c=d.find(".commentReplyLink");
    if(c.length){
        d.on("dblclick",function(){$(this).closest("div.com").find(".commentReplyLink").click()}).find(".t")}
    }
}

What it does is it takes a comment div on a website and it makes it into a large double-clickable area for you to open a reply. All I want to do is remove the double-clicking property so you can double-click text and highlight it instead of opening a reply modal dialog.

Since the function is anonymous, it cannot using removeEventListener to detach it. Any ideas? I prefer to not use jQuery.

It looks as though that event handler was attached through jQuery. It would probably be easiest also to remove it with jQuery... — Scott Sauyet

If jQuery is just Javascript, I'd prefer to write out one whole function from the library than including the entire library, which I won't be finding myself using. — dylanweber

The jQuery library is already included in your project, since this function you posted is jQuery-based. — Buzinas

It's not in the project, it just happens to interact with the jQuery in the site because in order to directly modify the JS of the page, I must inject my own JS through the content script. — dylanweber

Well, although you prefer not to use jQuery, it's much easier to use it, and my solution here will be jQuery-based, and feel free to convert it into a normal Javascript, if you want to.

function comments_endReply() {
    $("#ajax_comm div.com").off("dblclick");
}

I appreciate the response. It does work. I guess I might just use it, I seem to have some irrational fear of jQuery.

I'm not sure that fear is entirely irrational. But in the end, if you want someone to clean up a mess, who better than the one who made the mess in the first place?
