Question

点击li标签，我正在使用YQL并获取与之相关的数据。

请您告诉我如何以这种方式添加标题

名称，上次价格，更改，上次更新

我的代码的一部分

 if (DaysLow)
                {
   htmldata += '<tr>\
    <td>' + Name + '</td>\
    <td>' + LastTradePriceOnly + '</td>\
     <td>' + Change + '</td>\
    <td>' + ChangeinPercent + '</td>\
    <td>' + LastTradeTime + '</td>\
    </tr>';
                }
            }
        });

Answer 1

你需要发起你的

htmldata =  '<table><thead><th>Name</th><th>Last Price</th><th>Change</th><th>Last Updated</th></thead><tbody>';

 if (DaysLow)
                {
   htmldata += '<tr>\
    <td>' + Name + '</td>\
    <td>' + LastTradePriceOnly + '</td>\
     <td>' + Change + '</td>\
    <td>' + ChangeinPercent + '</td>\
    <td>' + LastTradeTime + '</td>\
    </tr>';
                }
            }
        });

htmldata += '</tbody></table>';

这里是fiddle

Answer 2

在for loop范围

之前添加以下代码行

htmldata += '<thead><th>Name</th><th>Last Price</th><th>Change</th><th>Last Updated</th></thead><tbody>';

在for loop范围

之后添加以下行

htmldata += '</tbody>';

   jQuery("ul.tabs-1 li").click(function () {
       fetchDataForGlobalIndices('#tab-1-1');
   });
   var asia_symbols = ["%5EAORD", "%5ETWII"];

   function fetchDataForGlobalIndices(clickedtab) {
       if (clickedtab === '#tab-1-1') {
           fetchJSONFromYQL(asia_symbols, clickedtab);
       }
   }

   function fetchJSONFromYQL(symbolsarray, clickedtab) {
       var htmldata = '';
       var promises = [];
       
       htmldata += '<thead><th>Name</th><th>Last Price</th><th>Change</th><th>Last Updated</th></thead><tbody>';
       
       for (var i = 0; i < symbolsarray.length; i++) {
           var symbol = symbolsarray[i].trim();
           var query = "select * from yahoo.finance.quotes where symbol = " + "'" + symbol + "'";
           var yql = "https://query.yahooapis.com/v1/public/yql?q=" + escape(query) + "&format=json&diagnostics=false&env=store://datatables.org/alltableswithkeys&callback=?";
           var request = $.ajax({
               url: yql,
               dataType: 'json',
               async: false,
               timeout: 4000,
               success: function (data) {
                   var DaysLow = data.query.results.quote.DaysLow;
                   var DaysHigh = data.query.results.quote.DaysHigh || DEFAULT;
                   var ChangeinPercent = data.query.results.quote.ChangeinPercent || DEFAULT;
                   var Name = data.query.results.quote.Name || DEFAULT;
                   var LastTradeTime = data.query.results.quote.LastTradeTime || DEFAULT;
                   var LastTradePriceOnly = data.query.results.quote.LastTradePriceOnly || DEFAULT;
                   var Change = data.query.results.quote.Change || DEFAULT;
                   if (DaysLow) {
                       htmldata += '<tr>\
    <td>' + Name + '</td>\
    <td>' + LastTradePriceOnly + '</td>\
     <td>' + Change + '</td>\
    <td>' + ChangeinPercent + '</td>\
    <td>' + LastTradeTime + '</td>\
    </tr>';
                   }
               }
           });
           promises.push(request);
       }
        htmldata += '</tbody>';
       jQuery.when.apply(null, promises).done(function () {
           jQuery(clickedtab).html(htmldata);
           promises.length = 0;
           promises = [];
           htmldata = '';
       })
   }
