My mistake was splicing the url in the jumped url, as follows:
var myBaseUrl="https://xxx/"; function do() { $.ajax({ url :myBaseUrl+"wechat/weChatUntie.action", cache : false, dataType : "json", type: "POST", .................
<button id="Untie" class="btn" onclick="do()">解绑账号</button><br/><br/>
Just change the posture, save the complete url of the splicing into a variable, and then access it:
<script type="text/javascript" charset="UTF-8"> var myBaseUrl="https://'xxx'"; function do() { $.ajax({ url: myBaseUrl, cache : false, dataType : "json", type: "POST", ................. } </script>
Wasted a morning, just such a broken question, hereby record!
over!
