<script> var adPos = document.getElementById('adp_top_ads'); var ad_id_720 = "8014640d-fd34-4b2e-9b1b-cc67234a2325"; var ad_id_650 = "2d1bb2c4-eb72-471d-9c80-1bf5514728c1"; var ad_id_300 = "df94a1a9-ae2f-432d-9a92-d93823ff4503"; var width = window.innerWidth; var ad_id = ad_id_720; if( width <= 768 ){ ad_id = ad_id_300; }else if( width <= 1435 ){ ad_id = ad_id_650; } adPos.innerHTML = '<div id="' + ad_id + '" class="_ap_apex_ad"></div>'; var adpushup = adpushup || {}; adpushup.que = adpushup.que || []; adpushup.que.push(function() { adpushup.triggerAd(ad_id); }); </script>

the parser will recognized <div id="' + ad_id + '" class="_ap_apex_ad"></div> to element tag，but it is only the js string。。。。
