我面临一个问题，我想通过向其传递变量来使我的 API 链接成为动态的。我的API是:http://api.fixer.io/latest?symbols=SGD,MYR 现在我想要最后两个值，即 SGD 和 MYR 作为我输入的输入字段中的动态变量。那么如何做到这一点呢？ 这是我的完整代码。
$(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 ) ;
}
});
});
});<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
</head>
<body align="center"><br/><br/><br/>
<h1> Welcome Currency Convertor </h1> <br/><br/>
Local CCY : <input type="text" id="value1"> <br/><br/>
Hotel CCY : <input type="text" id="value2"> <br/><br/>
<button> Show rate </button> <br/><br/>
<div id="records"> </div>
</body>
</html>帮帮我。提前致谢。
最佳答案
试试这个:
$(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);
}
});
});
});<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
</head>
<body align="center"><br/><br/><br/>
<h1> Welcome Currency Convertor </h1> <br/><br/> Local CCY : <input type="text" id="value1"> <br/><br/> Hotel CCY : <input type="text" id="value2"> <br/><br/>
<button> Show rate </button> <br/><br/>
<div id="records"> </div>
