Your selector is correct. Using the attribute-equals-selector
(docs), it will select input elements with that type.
您的选择器是正确的。使用attribute-equals-selector
(docs),它将选择具有该类型的输入元素。
You'll need to be sure the DOM is loaded before running it.
在运行之前,您需要确保 DOM 已加载。

$(function() {
$(':input[type="number"]').click(function () { alert('hello'); });
});

You don't need the colon at the beginning, that's for selecting types of input, like $('input:text')
开头不需要冒号,这是用于选择输入类型,例如 $('input:text')
so $('input[type="number"]').click(function () { alert('hello'); });
所以 $('input[type="number"]').click(function () { alert('hello'); });
works just fine
工作得很好

i think your problem is the ":" before input.
我认为您的问题是输入前的“:”。
try:
尝试:
$('input[type="number"]').click(function () { alert('hello'); });

As you can see here your code works well... http://jsfiddle.net/U47Vj/Maybe your Browser does not support this HTML5 Feature. In Chrome everything is fine. Same code in FF 3.6 breaks.
正如您在此处看到的,您的代码运行良好... http://jsfiddle.net/U47Vj/也许您的浏览器不支持此HTML5 功能。在 Chrome 中一切都很好。FF 3.6 中的相同代码中断。
