javascript Date（）。getTime（）不是一个函数 [英] javascript Date().getTime() is not a function
问题描述
由于某种原因，我正在获得2012年5月1日星期二16:43:03 GMT + 0900 （JST）没有方法'getTime'
当然，字符串没有方法
我在回调中开始使用这段代码，但是在 getTime（）在创建 var age 的行：
for（var i = 0; i
if（may_need_gc）{
var now = Date（）;
var created = Date（may_need_gc ['value']）;
var age = now.getTime（） created.getTime（）;
}
}）
}
我已经把它放下了，所以我的例子页面就是这样：
&l t;！DOCTYPE html PUBLIC - // W3C // DTD XHTML 1.0 Transitional // ENhttp://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">
< html xmlns =http://www.w3.org/1999/xhtml>
< head>
< meta http-equiv =Content-Typecontent =text / html; charset = UTF-8/>
< title>日期测试< / title>
< / head>
< body>
< script type =text / javascriptcharset =utf-8>
var now = Date（）;
alert（now.getTime（））;
var t = Date（）。getTime（）;
< / script>
< / body>
< / html>
Chrome 18.0.1025.168和Firefox 13.0中失败。
我尝试过的截图：
所以我的问题：
wth？ >
我必须使用ParseDate（）吗？为什么这不工作？
尝试使用新的关键字实例化一个新对象
，而不是这个
var now = Date（）;
尝试这个
code> var now = new Date（）;
I'm trying to compare some Dates in javascript.
For some reason, I'm getting "Tue May 01 2012 16:43:03 GMT+0900 (JST) has no method 'getTime'"
Of course, strings don't have methods
I started with this code inside a callback, but it was failing at getTime() on the line that creates var age:
for (var i = 0; i < array_of_usage_indices.length; i++) {
store.get(array_of_usage_indices[i]['key'],function(may_need_gc) {
if(may_need_gc) {
var now = Date();
var created = Date(may_need_gc['value']);
var age = now.getTime()-created.getTime();
}
})
}
I've pared it down so my example page is literally just this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>date test</title>
</head>
<body>
<script type="text/javascript" charset="utf-8">
var now = Date();
alert(now.getTime());
var t = Date().getTime();
</script>
</body>
</html>
This is failing in Chrome 18.0.1025.168 and Firefox 13.0.
Screenshots of what I've tried:
So my question:
wth?
Do I have to use ParseDate()? Why isn't this working?
Try using new keyword to instantiate a new object
so instead of this
var now = Date();
try this
var now = new Date();
