onclick 还是 onClick? [英] onclick or onClick?

问题描述

我以为在javascript中绑定点击事件是通过使用node.onclick完成的，Chrome/Firefox似乎和我一致，但我看到它写成.onClick 这里 3 人 4 次，所以这不可能是错字，我怀疑这是巧合.

I thought that binding the click event in javascript is done by using node.onclick, and Chrome/Firefox seem to agree with me, but I saw it written .onClick here 4 times by 3 people, so it can't be a typo and I doubt that it's a coincidence.

那么，当 onClick 不起作用时，为什么人们还要写呢?

So, why are people writing onClick when it does not work?

UPDATE:有两个很好的解释；我不知道其中哪一个最有道理，所以明天我将接受基于大众投票的答案.

UPDATE: There are two good explanations; I don't know which one of them is the most plausible, so I will accept the answer based on popular vote, tomorrow.

推荐答案

因为某些浏览器(取决于 DOCTYPE)可以容忍内联 onClick="something();" 属性...它似乎已经传播了一点，甚至在它不起作用的 JavaScript 问题中，因为大小写很重要.

Because some browsers (depending on the DOCTYPE) are tolerant of the inline onClick="something();" attribute...it seems to have spread a bit, even into JavaScript questions where it doesn't work, since case matters.

另外，特别是对于stackoverflow...人们在问题中使用它...嗯，如果他们的代码有效，大多数时候他们不会问问题:)

Also, specifically to stackoverflow...people using it in questions...well, most of the time they wouldn't be asking a question if their code worked :)
