javascript error { [native code] }
提问by ristenk1
Hi I'm trying to do some basic javascript and am getting "native code" instead of what I want:
嗨，我正在尝试做一些基本的 javascript 并且得到“本机代码”而不是我想要的：
<script type="text/javascript">
var today = new Date();
document.write(today + "<br />");
//document.write(today.length + "<br />"); - was getting "undefined"
//document.write(today[0] + "<br />"); - was getting "undefined"
document.write(today.getMonth + "<br />");
document.write(today.getMonth + "<br />");
document.write(today.getFullYear + "<br />");
</script>
output was:
输出是：
Fri Jan 13 14:13:01 EST 2012
function getMonth() { [native code] }
function getDay() { [native code] }
function getFullYear() { [native code] }
what I want is to get the current Month, Day, Year and put it into an array variable that I will be able to call later on. I'm not getting far because of this native code. Can someone tell me what it is and hopefully, more importantly I can complete this project? Thank you for your time and help, it is much appreciated!
我想要的是获取当前的月、日、年并将其放入一个数组变量中，以便稍后调用。由于这个本机代码，我没有走远。有人能告诉我它是什么吗，更重要的是我能完成这个项目吗？感谢您的时间和帮助，非常感谢！

The getMonthand the rest are functions, not properties, when you call just today.getMonthyou are getting a reference to the actual function. But, if you execute it using parenthesis, you get the actual result.
在getMonth剩下的都是函数，而不是属性，当你调用只是today.getMonth你得到的实际函数的引用。但是，如果使用括号执行它，则会得到实际结果。
Your code should be:
你的代码应该是：
document.write(today.getMonth() + "<br />");
document.write(today.getMonth() + "<br />");
document.write(today.getFullYear() + "<br />");

You are missing the parenthesis().
您缺少括号()。
document.write(today.getMonth() + "<br />");
document.write(today.getMonth() + "<br />");
document.write(today.getFullYear() + "<br />");

getMonthand getFullYearare functions, so you need to invoke them. Note the parentheses:
getMonth和getFullYear是函数，所以你需要调用它们。注意括号：
document.write(today.getMonth() + "<br />");
document.write(today.getMonth() + "<br />");
document.write(today.getFullYear() + "<br />");
As you have it, it's printing the string representations of the functions, not the functions' values.
正如您所拥有的，它打印的是函数的字符串表示，而不是函数的值。

document.write(today.getMonth() + "<br />"); // notice the ()'s to invoke the function
document.write(today.getMonth() + "<br />");
document.write(today.getFullYear() + "<br />");
