클라이언트 측 페이지와 서버 측 페이지는 도메인 간 호출 테스트를 용이하게 하기 위해 두 개의 프로젝트에 있습니다.

교차 도메인 인스턴스 코드(jquery를 로드해야 함, 페이지는 utf-8로 인코딩됨):

 <!--拉勾招聘数据-->
  <script type="text/javascript">
   function success_jsonpCallback(data){
    var html = &#39;&#39;;
    var pos = &#39;&#39;;
    html += &#39;<ul>&#39;;
    jQuery.each(data, function(k, v) {
                 if(k<10){
                  pos = &#39;【&#39; + v.city+ &#39;】&#39; + v.positionName + &#39;(&#39;+ v.salary +&#39;) - &#39;+v.companyName;
      if(pos.length > 20){
       pos = pos.substring(0,19)+&#39;...&#39;;
                     }
                     html += &#39;<li><a href="&#39;+v.posiitonDetailUrl+&#39;" target="_blank" title="【&#39; + v.city+ &#39;】&#39; + v.positionName + &#39;(&#39;+ v.salary +&#39;) - &#39;+v.companyName+&#39;">&#39;+pos+&#39;</a></li>&#39;;
                 }
    });
    html += &#39;</ul><div class="more-link"><a href="http://www.lagou.com/jobs/list_%E5%89%8D%E7%AB%AF%E5%BC%80%E5%8F%91" target="_blank">更多</a></div>&#39;;
