重新运行带有$ ajax对象的ajax调用？

Question

I'm a little confused about this and I hope some can help explain this to me. Using jquery $ajax I run something like this (the values here are not relevant):

$ajax = $.ajax({
    type: type,
    url: url,
    data: data,
    dataType: dataType, 
    success: callBack,
    cache: cache,
    error:function (xhr, ajaxOptions, thrownError) {
        dir(thrownError);
        dir(xhr);
        dir(ajaxOptions);
    }
  });

How can I run this every few seconds? Should I just wrap it in setInterval() or can I use $ajax.done and pass in the ajax call again recursively? I'm not necessarily asking what the best way is just an example of how I could do this.

Answer 1

You can use setInterval:

setInterval(function(){
      $ajax = $.ajax({
    type: type,
    url: url,
    data: data,
    dataType: dataType, 
    success: callBack,
    cache: cache,
    error:function (xhr, ajaxOptions, thrownError) {
        dir(thrownError);
        dir(xhr);
        dir(ajaxOptions);
    }
  });
},1000);

Please take a look at web sockets , it is better than ajax if you want it to be called periodically

Answer 2

setInterval

var call = function(){
   $.ajax({
    type: type,
   url: url,
   data: data,
   dataType: dataType, 
   success: callBack,
   cache: cache,
   error:function (xhr, ajaxOptions, thrownError) {
        dir(thrownError);
       dir(xhr);
       dir(ajaxOptions);
    }
}

and

   setInterval(call, 5000);
