javascript使用分号（/ \\ r \\ n | \\ n | \\ r /）

Question

I use the following code in javascript

console.log(result);
tmp = result.split(/\r\n|\n|\r/);
console.log(tmp);

to split the result which appears like:

x = 1;

y = 3;

z = 4;

into an array tmp, but i get the semicolon(;) as well

[ "x = 1;", "y = 3;", "z = 95;"]

what I need is

[ "x = 1", "y = 3", "z = 95"]

without the semicolon, what should I add?

Answer 1

I suppose you mean semicolon and not question mark. Anyway as the parameter inside the split function is a regex you can change it to match also the semicolon. If you are sure the semicolon will be there just use this:

tmp = result.split(/;\r\n|;\n|;\r/);

If you are not sure the semicolon is always there just use this one:

tmp = result.split(/;?\r\n|;?\n|;?\r/);

The ? in the last regex mean '0 or 1' so it check if the semicolon is there and if it is it use it as separator.

Answer 2

You can just replace them with nothing before doing the splitting:

 result = `x = 1; y = 3; z = 4;` console.log(result); tmp = result.replace(/;/g, "").split(/\\r\\n|\\n|\\r/); console.log(tmp);
