想改变path跳转后传的参数，但是这么写以后微信跳转图片都不见了难道是path的判断写错地方了吗

Question

想改变path跳转后传的参数，但是这么写以后微信跳转图片都不见了难道是
let launch = document.getElementById('launch-btn')
if(hxcjs.getUrlString("product_no").split("")[1]=="YINGBAO"){
let path = pages/index/index?source=wtProductB&to=h5tp&sourceType=wt&agentCode=${sales_agent}&linkUrl=${commonurl_front+'common/blank.html'}
launch.setAttribute('path',path)
}else if(hxcjs.getUrlString("product_no").split("")[1]=="YINGXIAO"){
let path = pages/index/index?source=wtProduct&to=h5tp&sourceType=wt&agentCode=${sales_agent}&linkUrl=${commonurl_front+'common/blank.html'}
launch.setAttribute('path',path)
}的地方写错了吗？
