CasperJS無法湊AJAX網頁

我想湊http://www.snapdeal.com/offers/deal-of-the-day其使用AJAX調用JSON數據加載到頁面如下：CasperJS無法湊AJAX網頁

json_url = http://www.snapdeal.com/json/getProductById?*

我使用的代碼塊下面，我得到的日誌消息Waiting for AJAX request:，但不是Waiting for AJAX request:，而不是waitForResource超時

casper.options.onResourceRequested = function (casper, requestData){ 
    // loop through our AJAX urls 
    // create list of AJAX urls to track 
    var ajaxUrls = [json_url]; 

    ajaxUrls.every(function(ajaxUrl){ 
     // does this request match an AJAX url 
     if(requestData.url.indexOf(ajaxUrl) !== -1){ 
      // it matches, so we'll wait for it to return (with 10s timeout) 
      //console.log("Waiting for AJAX request: " + requestData.url); 
      // print_object(requestData); 
      casper.waitForResource(requestData.url, function(){ 
       console.log("AJAX request returned: " + requestData.url); 
      }, function(){ 
       console.log("AJAX request didn't return after wait period: " + requestData.url) 
      }, 10000); 
     } 
    }); 
}

進一步調試，我記錄的事件，併成功接收的URL json_url資源，但不知道爲什麼waitForResource次。運行後

casper.on('resource.received', function(resource) { 
    if (resource.url.indexOf('http://www.snapdeal.com/json/getProductById') != -1){ 
     casper.echo('resource.received: ' + resource.url); 

    } 

});

你試過waitForSelector，它是一個更好地識別某些資源在該網頁上以及該資源上的waitForSelector。 – kumar

是我第二，你必須使用waitForSelector – user3833838

是的，我已經試過waitForSelector但它仍然無法正常工作。 –

你需要的是：

casper.waitForSelector()

或

casper.waitFor(function() { 
    // test here something that return true when the page is loaded 
})
