在 JQuery .trigger 上传递参数

发布于05月06日

I am using JQuery trigger but am not sure what the correct syntax is to pass parameters in my situation. Here is where I am making the call :

$('#'+controlName).trigger(event);

下面是我进行事件绑定的地方:

$(window).on('onPartialRendered', onPartialRendered);

下面是我的事件处理程序:

var onPartialRendered = function () {

    .....
};

Everything works fine until I try to pass parameters. What would be the correct way to do it as per my example?

推荐答案

First parameter is always string with event name and next parameters are additional data:

.trigger('foo', [1, 2]);

.on('foo', function(event, one, two) { ... });

特别感谢火箭危险品

例子:

var controller = {
  listen: function (event, json, string) {}
};

$('body').trigger('this_works', [{data: [1, 2, 3]}, 'something']);

$('body').on('this_works', function (event, json, string) {
  controller.listen(event, json, string);
});

请不要用这种方式.网络上有很多关于这个问题的文章.这需要很多时间，并在网络中产生不必要的流量.请用这种方式:

var template = $('#templates #example_template').detach();
var clone = template.clone();
clone.find('.some_field').val('new_data');
clone.attr('id', null);
$('table tbody').append(clone);
