How to stop all active ajax requests in jQuery without trigerri

Answer 1

Just as important: say you want to log off and you are generating new requests with timers: because session data is renewed with each new bootstrap (maybe you can tell I am talking Drupal, but this could be any site that uses sessions)... I had to go through all my scripts with a search and replace, cause I had a ton of stuff running in different cases: global variables at the top:

var ajReq = [];
var canAj = true;
function abort_all(){
 for(x in ajReq){
    ajReq[x].abort();
    ajReq.splice(x, 1)
 }
 canAj = false;
}
function rmvReq(ranNum){
 var temp = [];
 var i = 0;
 for(x in ajReq){
    if(x == ranNum){
     ajReq[x].abort();
     ajReq.splice(x, 1);
    }
    i++;
 }
}
function randReqIndx(){
 if(!canAj){ return 0; }
 return Math.random()*1000;
}
function getReqIndx(){
 var ranNum;
 if(ajReq.length){
    while(!ranNum){
     ranNum = randReqIndx();
     for(x in ajReq){
    if(x===ranNum){
     ranNum = null;
    }
     }
    }
    return ranMum;
 }
 return randReqIndx();
}
$(document).ready(function(){
 $("a").each(function(){
    if($(this).attr('href').indexOf('/logout')!=-1){          
     $(this).click(function(){
    abort_all();                 
     });
    }
 })
});
// Then in all of my scripts I wrapped my ajax calls... If anyone has a suggestion for a 
    // global way to do this, please post
var reqIndx = getReqIndx();
if(reqIndx!=0){
ajReq[reqIndx] = $.post(ajax, { 'action': 'update_quantities', iids:iidstr, qtys:qtystr },  
function(data){
 //..do stuff
 rmvReq(reqIndx);
 },'json');
}
