This is my first ever post & I'm very inexperienced so please go easy on me, but I feel I've got a valid contribution that may be helpful to someone...

Sometimes you need a very big time window between repeat clicks (eg a mailto link where it takes a couple of secs for the email app to open and you don't want it re-triggered), yet you don't want to slow the user down elsewhere. My solution is to use class names for the links depending on event type, while retaining double-click functionality elsewhere...

var controlspeed = 0;

$(document).on('click','a',function (event) {
    eventtype = this.className;
    controlspeed ++;
    if (eventtype == "eg-class01") {
        speedlimit = 3000;
    } else if (eventtype == "eg-class02") { 
        speedlimit = 500; 
    } else { 
        speedlimit = 0; 
    } 
    setTimeout(function() {
        controlspeed = 0;
    },speedlimit);
    if (controlspeed > 1) {
        event.preventDefault();
        return;
    } else {

        (usual onclick code goes here)

    }
});
