Question

我收到错误：Uncaught SyntaxError：意外的标记＆lt;

我只是遇到了Google Trend URL的这个问题。其他网址工作正常。

function ajaxfun(){

  $.ajax({
    type: 'GET',
    url: 'http://www.google.com/trends/fetchComponent?content=1&hl=en-US&q=fever&cid=TIMESERIES_GRAPH_0&export=3&US&cat=0-45', 
    dataType :"jsonp",
    jsonp: false,
    crossDomain: true,
    error: function(data) {
      console.log('error', data);
    },
    success: function(data) {
      console.log('success', data);
    },
    complete: function() {
      console.log('done');
    }
  });
}

Answer 1

您实际上并没有收到json对象。它说，

<div id="report">
<div class="timeBandTitle">An error has been detected</div>
<div class="timeBandSubTitle">This page is currently unavailable. Please try again later.<br/> Please make sure your query is valid and try again.<br/> If you're experiencing long delays, consider reducing your comparison items.<br/> Thanks for your patience.</div>

Demo 使用开发人员工具进行检查，并在网络标签中查看。

默认情况下，jQuery通过在网址末尾附加&_={timestamp}来阻止jsonp的缓存。它会导致错误。添加cache:true以防止它。
