Question

如何在javascript / jquery中设置以在特定事件中挂钩特定功能，例如wordpress动作挂钩如何工作

基本代码

$('body').on('click', '[data-modal]', function() {
    var dis = $(this).data('modal');
    // how can I hook something in here from outside this file
    $('#'+dis).addClass('is-active');
    // I also want to hook and run a function in here without directly calling them
});

以下是我想要实现的目标

$('body').on('click', '[data-modal]', function() {
    var dis = $(this).data('modal');

    trigger('before_open_' + dis); // I don't know what method to use here

    $('#'+dis).addClass('is-active');

    trigger('after_open_' + dis); // I don't know what method to use here
});

// I don't also know how to properly initialize the event
$(document).on('before_open_classes_pop', function() {
    console.log( $(this).data('modal') );
});

任何帮助将不胜感激

首先创建custom events

$( "[data-modal]" ).on( "before_open", function(){
   var dis = $(this).modal();
   //logic to handle the before open event for a specific dis here
});

和

$( "[data-modal]" ).on( "after_open", function(){
   var dis = $(this).modal();
   //logic to handle the after open event for a specific dis here
});

现在以

的形式调用这些事件

$('body').on('click', '[data-modal]', function() {
    var dis = $(this).data('modal');
    $(this).trigger('before_open'); 
    $('#'+dis).addClass('is-active');
    $(this).trigger('after_open');
});
