Javascript使用总结

有时需要根据特定的字符分割字符串，比如根据换行符号分割查询条件。如果条件严格以单个换行符相隔，可以使用如下语句进行分割。

1	let paramList = values.param.toString().split("\n");

不过大多数情况，条件之间并不能严格保证以单个换行符相隔，往往是一个或者一个以上换行符。那么可以使用正则表达式：

// 一个或者一个以上换行符
let paramList = values.param.toString().split(/\n+/);
//一个或者一个以上空格
let paramList = values.param.toString().split(/\s+/);

在Javascript中换行符只有\n,没有\n与\n\r的区分。

In Javascript, new lines are represented by a single “\n” character.
Textarea values might have the character combos “\n\r” in the text box, but once they are pulled into Javascript, “\n\r” becomes JUST “\n”.
When replacing out new line characters, treat them as you would any other character. They are not special, they just have special notation.
