javascript - 确认前执行

Question

有什么方法可以在确认启动之前停止功能开启时的间隔吗？

function check(){
    clearInterval(interval_id);
    if(confirm('Stream time is running out. Do you want to continue?'))
        //
}

Answer 1

如果您想要的话，您可以将自己的代码 Hook 到 confirm 中:

window.proxiedConfirm = window.confirm;
window.confirm = function() {
   // custom interval code here
   return window.proxiedConfirm.apply(this, arguments);
};

您当然也可以手动收听响应:

window.proxiedConfirm = window.confirm;
window.confirm = function() {

   // custom interval code here

   var result = window.proxiedConfirm.apply(this, arguments);

   if(result) {
      // start interval again?
   }

   return result;
};
