重试jquery ajax请求,该请求附加了延迟的回调

function retryAjax(options, retries, delay) {
  var internalOptions = $.extend({}, options, {
    success: function(data, textStatus, jqXHR) {
      options.success(data, textStatus, jqXHR);
    },
    error: function(jqXHR, textStatus, errorThrown) {
      if (retries > 0) {
        setTimeout(function() {
          retryAjax(options, retries - 1, delay);
        }, delay);
      } else {
        options.error(jqXHR, textStatus, errorThrown);
      }
    }
  });

  $.ajax(internalOptions);
}

// 使用示例
retryAjax({
  url: "http://example.com/api/data",
  dataType: "json",
  type: "GET",
  success: function(data) {
    console.log("请求成功", data);
  },
  error: function(jqXHR, textStatus, errorThrown) {
    console.log("请求失败", textStatus, errorThrown);
  }
}, 3, 1000); // 重试3次，每次重试之间的延迟为1000毫秒
