call multiple functions from single event with unobtrusive javascript
提问by dan_vitch
I have an input element
我有一个输入元素
<select id="test"></select>
on change I want to call multiple functions
更改时我想调用多个函数
$('#test').change(function1, function2);
functions for now are just alerts for now
现在的功能只是现在的警报
var function1 = function(){alert('a');};
var function2 = function(){alert('b');};
Only the second function is being called. I know this because of alerts and brake points. I know one way to correct this would be to call function1, and function2 from another function, but I would like to avoid that.
只有第二个函数被调用。我知道这是因为警报和刹车点。我知道纠正这个问题的一种方法是从另一个函数调用 function1 和 function2，但我想避免这种情况。

I prefer not to use anonymous functions so I would create a new function and place all work inside it.
我不喜欢使用匿名函数，所以我会创建一个新函数并将所有工作放在其中。
$('#test').change(onSelectChange);
var onSelectChange = function() {
function1();
function2();
}
