你好,我调用了一个 json 文件并显示了一些错误,你能帮帮我吗

显示错误Uncaught ReferenceError: marketlivedata is not defined

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<!DOCTYPE html>
<html xmlns:xhtml="http://www.w3.org/1999/xhtml" xmlns:g="http://base.google.com/ns/1.0">

<head>
<title>Data Call to json</title>



<script type="text/javascript">
// =====================
$(document).ready(function(e) {
// alert('hello');
// var marketlivedata ;
});
// =====================
function getUserData() {
$.ajax({
type: "GET",
url: "http://xxxxxxxxx.xxxxxxx.com/xxxxxxx.json",
dataType: 'jsonp',
crossDomain: true,
success: function(data) {
// $('#ajexLoaderSec').hide();
console.log(data);

},
error: function(e) {
alert("There is an error while connecting to the server. Please try after some time");
}
});
};
getUserData();
</script>
</head>

我的json格式是

marketlivedata([{"sensex":{"trend":"equal","CloseIndexValue":"24893.81","premarket":"false","DateTime":"11:41 AM | 08 Sep 2015","CurrentIndexValue":"24958.31","Segment":"BSE","OpenIndexValue":"24972.01","PercentChange":"0.26","IndexName":"SENSEX","NetChange":"64.50"},"nifty":{"trend":"equal","CloseIndexValue":"7558.80","premarket":"false","DateTime":"11:41 AM | 08 Sep 2015","CurrentIndexValue":"7582.85","Segment":"NSE","OpenIndexValue":"7587.70","PercentChange":"0.32","IndexName":"CNX NIFTY","NetChange":"24.05"},"gold":{"ClosePrice":"26500.00","trend":"negative","OpenPrice":"26499.00","ExpiryDate":"2015-10-05","SpotSymbol":"SGOLDAHM","LastTradedPrice":"26441.00","DateTime":"8-September-2015 11:34:22","Symbol":"GOLD","PercentChange":"-0.22","CommodityName":"Gold","NetChange":"-59.00","PriceQuotationUnit":"10 GRMS ","SpotPrice":"26401.0"},"silver":{"ClosePrice":"35193.00","trend":"equal","OpenPrice":"35176.00","ExpiryDate":"2015-12-04","SpotSymbol":"SSILVERAHM","LastTradedPrice":"35070.00","DateTime":"8-September-2015 11:34:0","Symbol":"SILVER","PercentChange":"-0.35","CommodityName":"Silver","NetChange":"-123.00","PriceQuotationUnit":"1 KGS  ","SpotPrice":"34815.0"},"USD/INR":{"DateTime":"2015-09-08 11:36:02.0","percentChange":"-0.27","netChange":"-0.18","name":"USD/INR","bidprice":"66.65"},"DXY Index":{"DateTime":"2015-09-08 11:39:40.0","percentChange":"-0.1","netChange":"-0.1","name":"DXY Index","bidprice":"96.13"},"marketstatus":{"currentMarketStatus":"Live"}}])

最佳答案

返回的数据是marketlivedata(...)。这是在调用 marketlivedata 函数,该函数未在您的脚本中定义。由于您已将 dataType 用作 jsonp,因此函数已执行。

要解决此问题,您可以更改 JSON 服务器的数据格式(这可能无法实现,因为这看起来像第三方服务),或者您可以定义一个具有该名称的函数,该函数将在响应到达时调用。

function getUserData() {
$.ajax({
type: "GET",
url: "http://mobilelivefeeds.indiatimes.com/homepagedatanew.json",
dataType: 'jsonp',
crossDomain: true,
success: function(data) {
// $('#ajexLoaderSec').hide();
console.log(data);

},
error: function(e) {
console.log(e);
}
});
};
getUserData();


function marketlivedata(data) {
console.log(data);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
