将对象数组转换为数组，但格式不同。

Question

I have an array of objects as shown below. I did a console.log(values); and got below result

["15- S&P", "us- ex US", "al- ex CL"]

0:"15- S&P"
1:"us- ex US"
2:"al- ex CL"
length:3
__proto__:Array(0)

I want the output in a array with values as follows.

[S&P, ex US, ex CL]

All values before the '-' are eliminated and values after '-' are taken and put in an array. for eg '15- S&P' is changed to 'S&P'. Can anyone please let me know how to achieve this.

Answer 1

You could use Array#map and String#split to return just the text after - sign from every element.

 var arr = ["15- S&P", "us- ex US", "al- ex CL"], res = arr.map(v => v.split("- ")[1]); console.log(res); 

Answer 2

You may also try this;

 var arr = ["15- S&P", "us- ex US", "al- ex CL"], res = arr.map(s => s.replace(/\\w+-\\s*([\\w&\\s]+)/,"$1")); console.log(res);
