好吧，你的问题格式有点糟糕，我觉得你想要点击确定的东西，点击取消时会有不同的东西，如果是这样，我建议你使用不同id的函数，例如：

<button id="ok" onclick="dosomething(this.id);"></button>
<button id="cancel" onclick="dosomething(this.id);"></button>

<script>
// this is the most important, for separate the diferent actions //
function dosomething(a) {
    if (a === "ok") {
       // your code of the popup ok //
    }
    if (a === "cancel") {
       // the code of the popup cancel //
    }
}
</script>
