Question

我正在玩笑,想呼吁提供因特网服务,即知道如何这样做,但服务器呼吁继续运行,直到从服务器得到具体答复。

我将等到每个周期的3秒钟。

function servercall() {
            while (true) {
                // code for clone and insert  ...
                $.ajax({
                    type: "POST",
                    url: "Server.asmx/HelloWorld",
                    data: "{ name :  " + $( #name ).val() + " ,  time :  2pm }",
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    success: function(msg) {
                        AjaxSucceeded(msg);
                    },
                    error: AjaxFailed
                });
                setTimeout("nothing", 2000);
            }

        }

Answer 1

使用<条码>准时。确实,当你收到答复时,就开始时间,以便你能够说明网络的拖延(你不想同时提出大量要求)。

function servercall() { 
  $.ajax({ 
    complete: function(xhr) { 
      var msg = xhr.responseText;
      if(xhr.statusCode == 200)
        AjaxSucceeded(msg); 
      else
        AjaxFailed(msg);

      setTimeout(servercall, 2000); //recursion magic
    }
  }); 
}

Answer 3

你可以尝试:

function serverCall() {
    // ajax code

    setTimeout("serverCall()", 2000);
}

或

function ajaxSucceeded(msg) {
    if (isTheAnswerYouAreLookingFor) {
        // do stuff
    } else {
        setTimeout("serverCall()", 2000);
    }
}

Answer 4

间隔时间更有助于:

<script type= text/javascript >

setInterval("servercall()", 2000);

function servercall() {

                // code for clone and insert  ...
                $.ajax({
                    type: "POST",
                    url: "Server.asmx/HelloWorld",
                    data: "{ name :  " + $( #name ).val() + " ,  time :  2pm }",
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    success: function(msg) {
                        AjaxSucceeded(msg);
                    },
                    error: AjaxFailed
                });

            }

        }

</script>
