javascript函数调用计时。 实施此的最佳方法

Question

I have The following in my main javascript file:

window.onbeforeunload = function () {
    firstFunction();
}

$("a").live("click", function() {
   secondFunction();
}

When user clicks on any link that unloads the page (ie navigate to another page), both of those functions get called; FirstFunction() gets called first, then secondFunction() gets called. I want the secondFunction() to get called before the firstFunction();

I was able to achieve this by doing this: setTimeout('firstFunction(),100), but I am wondering if there is a better way of doing this?

Thanks.

Answer 1

我建议您使用mousedown事件而不是click。

Answer 2

Try this - give all external links a class="external"

window.onbeforeunload = function () {
    firstFunction();
}
$(document).ready(function() {
  $("a").click(function() {
     if ($(this).hasClass("external")) secondFunction();
  });
});
