Passing parameters on JQuery .trigger

javascriptjquery

提问by user517406

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 :

我正在使用 JQuery 触发器,但不确定在我的情况下传递参数的正确语法是什么。这是我打电话的地方:

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

Here is where I am doing the event binding :

这是我进行事件绑定的地方:

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

And here is my event handler :

这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?

一切正常,直到我尝试传递参数。根据我的示例,正​​确的方法是什么?

回答by Eraden

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

第一个参数始终是带有事件名称的字符串,下一个参数是附加数据:

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

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

特别感谢 Rocket Hazmat

Example:

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);
});

Please do not use this way. There is many article about this problem in network. This take much time and generate unnecessary traffic in network. Please use this way:

请不要使用这种方式。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。请使用这种方式:

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);
