1. Prohibit a tag from jumping href="javascript:void(0)"
2. Request ajax in the onclick method. After success, bind the return value to href

All default events in the browser can be disabled using event.preventDefault(). The rest is in your callback function, and you can do whatever you want. Of course, if you need to be compatible with IE8 and The following, compatible writing methods are as follows:

// event 为你的监听onclick回调函数中传递的参数
event.preventDefault ? event.preventDefault() : (event.returnValue = false);
