如何使用JavaScript检查是否单击了Button
问题描述：
我只是好奇是否有一种简单的方法可以按照这些方式做点什么：
I'm just curious if there is a simple way to do something along these lines:
javascript：
javascript:
if(document.getElementById('button').clicked == true)
{
alert("button was clicked");
}
html：
<input id="button" type="submit" name="button" value="enter"/>
答
您可以为此添加点击事件处理程序：
You can add a click event handler for this:
document.getElementById('button').onclick = function() {
alert("button was clicked");
};
如果你想跟踪它，它会在点击时发出警告以后，只需在该函数中将变量设置为true而不是警告，或者变量++ 如果您想计算点击次数，无论您的最终用途是什么。 您可以在此处查看示例。
This will alert when it's clicked, if you want to track it for later, just set a variable to true in that function instead of alerting, or variable++ if you want to count the number of clicks, whatever your ultimate use is. You can see an example here.
