重試Ajax調用錯誤5秒

Question

在這個片段中，$。阿賈克斯（本）之後，我需要的是使五種Ajax調用，但我需要每個請求之間的五個秒的延遲。請幫忙！

$.ajax({ 
    type: "POST", 
    data: JSON.stringify(download), 
    contentType: "application/json", 
    url: '', 
    retryCount: 1, 
    retryLimit: 5, 
    success: function(data) { 
    $.ajax({ 
     type: "GET", 
     url: '', 
    }) 
     .success(function(data) { 

    }) 
     .error(function(data) { 

    }) 
    }, 
//It has to go into error 
    error : function(xhr, textStatus, errorThrown) { 
    this.retryCount++; 
    if (this.retryCount <= this.retryLimit) { 
     //try again 
     $.ajax(this); 
     return; 
    } else { 
     //user comes here After trying in the if loop for 5 times, with each request having five seconds delay. I am not able to keep delay between each request 
    } 
    return; 
    } 

});

試試這個：

error : function(xhr, textStatus, errorThrown) { 
    this.retryCount++; 
    if (this.retryCount <= this.retryLimit) { 
     //try again 
     var ajaxObject = this; 
     window.setTimeout(function(){ 
      $.ajax(ajaxObject); 
     },5000); 

     return; 
    } else { 
     //user comes here After trying in the if loop for 5 times, with each request having five seconds delay. I am not able to keep delay between each request 
    } 
    return; 
    }

嘗試包裝你的Ajax調用是這樣的：

setTimeout(function() { 
    $.ajax(this); 
}, 5000);
