javascript - Two jQuery operations trigger the same function, how to optimize the writing?

Question

{Code...} For example, if you click a button or press Enter in the input box to perform the same operation, can it be optimized into the following type of code: {Code...}

怪我咯 · Answer

Generally I like to use hosting

$('.container').on('click', '.btn', function(e) {
    // 只有在点击 .container 下的 .btn 元素才运行, this 只想的是 .btn 元素
    // 而且 不需要考虑你的 .btn 是否存在, 是否后加载
});

If your two operations have something in common, you can use the same class name to identify and bind events
If they are of different types, your first method is fine
