Question

我有ajax的任务，即jquery ajax。我有2页main.php和ajx_receipt_sub_detail.php。我在加载ajax页面时有延迟。任何人都建议加快ajax加载的速度。

main.php

<script src="scripts/jquery-1.11.0.min.js"></script>
 <script>
function sub_detail(id)
{
   setTimeout(function() {
  $.ajax({
    type: "POST",
    url: 'ajx_receipt_sub_detail.php',
    data:'id='+id + '&exchange_rate=' + exchange_rate,
    success: function(msg)
     { 
      $("#sub_detail").html(msg);
      $(function() {
        $( "#slip_date2" ).datepicker({dateFormat:'yy-mm-dd'});
          });
     }
     }); 
   }, 10);  
  }
  </script>
  <select name="deposited_type" id="deposited_type" onchange="sub_detail(this.value)">
                                <option     value="">Select</option>
                <option value="Direct Bank Deposit">Direct Bank Deposit</option>
                <option  value="CDM">CDM</option>
                <option  value="Cash Handover">Cash Handover</option>

                 <option value="Western Union">Western Union</option>

Answer 1

根据我的理解，您希望快速响应ajax。可能有许多因素会影响请求的加载/处理时间。这取决于服务器的功能，脚本代码等。

您可以参考此处以减少ajax通话的处理时间：http://www.peachpit.com/articles/article.aspx?p=1851233

Answer 2

您可以使用jquery setTimeout()。

setTimeout(function() { /* Your Code */ }, 4000);

（这将在执行ajax请求之前等待四秒钟。）

如果您想了解有关setTimeout()的详情，请参阅此处

https://developer.mozilla.org/en/docs/Web/API/window.setTimeout

试试这个： -

<script>
function sub_detail(id)
{
$.ajax({
type: "POST",
url: 'ajx_receipt_sub_detail.php',
data:'id='+id + '&exchange_rate=' + exchange_rate,
success: function(msg)
{ 
  $("#sub_detail").html(msg);
  $(function() {
  $( "#slip_date2" ).datepicker({dateFormat:'yy-mm-dd'});
  });

   //TO SET THE TIMEOUT FOR DATA TO LOAD

  setTimeout(function(){
          sub_detail();
       }, 10000);
}
});  
}
</script>
