Comparison Operators - Greater than or Equal to - Not Working
提问by user2638054
Just started using JQuery recently. (Fairly recently, I suppose...) What am I doing wrong here?
最近刚开始使用JQuery。（最近，我想......）我在这里做错了什么？
var userDate = new Date();
if(userDate.getHours() => 12)
{
var post = $('p[title="test"]');
post.text('Would you look at the time?');
}

The condition is flipped.
条件翻转。
var userDate = new Date();
if(userDate.getHours() >= 12)
{
var post = $('p[title="test"]');
post.text('Would you look at the time?');
}

You probably need to use >=instead of =>, wrong sequence of greater or equal operator. The equal to = comes after > then in >=comparison operator. You can read more about comparion operators here.
您可能需要使用>=而不是=>，更大或等于运算符的错误序列。等于 = 在 > 之后，然后在>=比较运算符中。您可以在此处阅读有关比较运算符的更多信息。
var userDate = new Date();
if(userDate.getHours() >= 12)
{
var post = $('p[title="test"]');
post.text('Would you look at the time?');
}
Greater than or equal
>=Returns true if the left operand is greater than or equal to the right operand, reference.
大于或等于
>=返回true，如果左操作数大于或等于右操作数，参考。

if(userDate.getHours() => 12) {...}
Should be
应该
if(userDate.getHours() >= 12) {...}
The wrong way round maybe?
也许是错误的方式？

I must admit sometimes I get confused with the less than or equal toor greater than or equal to.
我必须承认，有时我会与小于或等于或大于或等于.
less than or equal to is
小于或等于是
<=
greater than or equal to is
大于或等于是
>=
But, if you can't remember these and your code isn't working it's always worth to simplify it buy doing something like this.
但是，如果您不记得这些并且您的代码不起作用，那么简化它总是值得购买做这样的事情。
var userDate = new Date();
if(userDate.getHours() > 11){
var post = $('p[title="test"]');
post.text('Would you look at the time?');
}
This means
这意味着
Greater than eleven
大于十一
This is the same but I think it's easier to understand, it must be 12 or greater
这是一样的，但我认为它更容易理解，它必须是12 或更大
