localeTitle: 了解Ruby字符串
|

|
||
### 基本：
|
||
|
||
* 字符串是引号之间串联的一系列字符。
|
||
|
||
* 单引号或双引号可用于在Ruby中创建字符串。
|
||
|
||
* Ruby对使用双引号创建的字符串进行了一些额外的评估，例如：
|
||
|
||
* 转义字符： `\n` ， `\t` ， `\s`
|
||
|
||
* 在里面使用变量和表达式： `#{variable or expression}`
|
||
|
||
* 带单引号的字符串按原样呈现，没有任何特殊注意事项。
|
||
|
||
|
||
## 例子：
|
||
```
|
||
"Hello World"
|
||
# is equivalent to:
|
||
'Hello World'
|
||
|
||
"This is line 1.\nAnd this is line 2."
|
||
# returns:
|
||
This is line 1.
|
||
And this is line 2.
|
||
|
||
name = "Batman"
|
||
"Hello, my name is #{name}!"
|
||
# returns:
|
||
Hello, my name is Batman!
|
||
|
||
# Note that for single quotes, ruby doesn't take special consideration for variables or backslashes:
|
||
'This is your name:\n#{name}'
|
||
# returns:
|
||
This is your name:\n#{name}
|
||
```
