Coinmarketcap API不起作用

Question

Below is an API that I have for coinmarketcap.com. 以下是我为coinmarketcap.com提供的API。 I am trying to pull the current price and place that into a table. 我正在尝试提取当前价格并将其放入表格中。 For some reason this code is not working and I can not figure out the error. 由于某种原因，此代码无法正常工作，我无法找出错误。 Any help is greatly appreciated. 任何帮助是极大的赞赏。

    $.get("https://api.coinmarketcap.com/v1/ticker/", function(data, status) {                  
      for (var i = 0; i < data.length - 1; i++) {                    
        if (data[i].id == "pivx") {                          
          $("#my_cell").innerHTML = data[i].price_usd;                    
        }                  
      }

Your code has a couple of problems. 您的代码有两个问题。 Firstly, your JS is missing a closing ) on the $.get method. 首先，您的JS缺少$.get方法的结尾) 。 You should remember to format your code correctly, then it's almost impossible to miss syntax errors like that. 您应该记住正确格式化代码，然后几乎不可能错过这样的语法错误。 Secondly, the td should be wrapped in a <tr> in the HTML. 其次，应将td包装在HTML的<tr>中。

The main issue however is that you're attempting to use innerHTML on a jQuery object when they do not have that property. 然而，主要的问题是，你试图使用innerHTML jQuery对象时，他们没有这样的属性。 Instead use html() , like this: 而是使用html() ，如下所示：

 $.get("https://api.coinmarketcap.com/v1/ticker/", function(data, status) { for (var i = 0; i < data.length - 1; i++) { if (data[i].id == "pivx") { $("#my_cell").html(data[i].price_usd); } } });

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <table> <tr> <th>Coin Price</th> </tr> <tr> <td id="my_cell"></td> </tr> </table>
