jQuery .on多个事件和选择器

Question

目前,我有一个缓存变量,$this我正在申请.on响应各种可能类型的行为触发器.

$this.on('click','.trigger a',rowTrigger);
$this.on('click','.actions nav a',rowAction);

在jQuery .on Documentation中,它没有提到是否有办法将上述两个组合成一个单独的调用.例如,像这样的东西可能会很好:

$this.onAny({
    click: [
        {'.trigger a':rowTrigger},
        {'.actions nav a':rowAction}
    ]
});

有没有办法实现这种声明(例如现有的扩展插件.on)？

UPDATE

用例(在当前代码中,在一个很好的解决方案之前):

// Plugin 1:
function addTriggers(){
  $this.find('td:last').append('<span class="trigger"><a href="#"></a></span>');
  return {selector:'.trigger a', event:'click', target: $this, callback: rowTrigger};
}

// Plugin 2:
function addInlineNavigation(){
  $navCode = '...'
  $this.find('td:last').append('<div class="actions">'+$navCode.html()+'</div>');
  return {selector:'.actions nav a', event:'click', target: $this, callback: rowAction};
}

Answer 1

有没有办法实现这种声明(例如现有的扩展插件.on)？

我不知道一个.写作几乎是微不足道的.然而,与链接相比,我没有看到它有多大优势:

$this.on('click','.trigger a',rowTrigger)
     .on('click','.actions nav a',rowAction);

但同样,插件并不复杂.这是一个未经测试的草稿:

jQuery.fn.onAny = function(options) {
    var eventName, eventSpec, eventEntry, selector, i;

    for (eventName in options) {
        eventSpec = options[eventName];
        if (jQuery.isArray(eventSpec)) {
            // Your example, where each event name has an array of objects
            // keyed by selector, where the value is the handler
            for (i = 0; i < eventSpec.length; ++i) {
                eventEntry = eventSpec[i];
                for (selector in eventEntry) {
                    this.on(eventName, selector, eventEntry[selector]);
                }
            }
        }
        else {
            // Assuming just a straight handler here
            this.on(eventName, eventSpec);
        }
    }

    return this;
};
