一般需要技术对接的，去找找要跳转过去的小程序相关官网找到对接文档，一般情况下，前端跳转必要参数 appId，path，query三个主要参数。 或者可以通过短链的方式跳转，但短链需要服务端对接后提供给前端。

尝试下，在自己域名服务下做个代理，代理到其他域名下？

console.log(jsontxt['detail][i]) jsontxt[detail] 是个对象，此时 i 是 [0,len-1]中的数字，而jsontxt[detail][0] , jsontxt[detail][1] 是不纯在的。 遍历detail for(let i in jsontxt.detail){     console.log(jsontxt.detail[i]) }
