Question

我正面临一个问题，我希望通过将变量传递给它来使我的API链接成为动态链接。我的API是：http://api.fixer.io/latest?symbols=SGD,MYR 现在我想要最后两个值，即SGD＆amp; MYR作为我输入的输入字段的动态变量。那怎么做？这是我的完整代码。

＆＃13;

$(function(){
   $('button').on('click' , function(){
      var val1 = document.getElementById('value1').value;
      var val2 = document.getElementById('value2').value;

      var $records = $('#records');

      $.ajax({
	       type: 'GET' ,
               url: "http://api.fixer.io/latest?symbols="+val2+","+val1,  //value are not coming to the link 
               success: function(data) 
               {
                   console.log(val1);      // values are coming here
	           console.log(val2);     // values are coming here
         	   var rate1 = data.rates.val1 ;
        	   var rate2 = data.rates.val2 ;
        	   var final = rate1/rate2 ;
        	   $('#records').html ('Total Rate for Above Currency is :  ' + final ) ;
               }
            });
        });
   });

试试这个：

＆＃13;

$(function() {
  $('button').on('click', function() {
    var val1 = document.getElementById('value1').value;
    var val2 = document.getElementById('value2').value;
    var $records = $('#records');
    var composedUrl = "http://api.fixer.io/latest?symbols=" + val1 + "," + val2;

    console.log(composedUrl);

    $.ajax({
      type: 'GET',
      url: composedUrl,
      success: function(data) {

        var rate1 = data.rates[val1];
        var rate2 = data.rates[val2];

        console.log(rate1);
        var final = rate1 / rate2;
        $('#records').html('Total Rate for Above Currency is :  ' + final);
      }
    });
  });
});
