jQuery event binding on() and pop-up window implementation code_jquery

There are often pop-up windows on the page. Some pop-up windows are dynamically generated, and some pop-up windows are hidden at the bottom of the page. For dynamically generated pop-up windows, if you want to monitor the pop-up window events, you can use jQuery Event binding on() method is implemented.

As shown in the picture, the pop-up window is dynamically generated by js. It pops up by clicking a link. After clicking the "Use Now" link in the pop-up window, the effect is to close the pop-up window and jump to the anchor point.

This a tag is:

We need to monitor the click event in the pop-up window, but the pop-up window itself is dynamically generated, so we need to monitor the body and bind it through the on() event. When the pop-up window is dynamically generated, the click method can be monitored :

function jump_to_anchor() {
  $("body").on("click", "span[name='msgbox_info'] a, .act-pop-table a", function (e) {
    link = $(this).attr('href');
    if (link == 'http://act.vip.***.com/vip/2016/51dps/#gamelist') {
      e.preventDefault();
      msgExit();
      window.location.href = link;
    }
  });
}

This is actually an event binding with two a tags. When the link is a certain URL, the default behavior is blocked, and the pop-up window closing method is called to jump to the link, which is the anchor point. .
