Javascript：将字符串转换为带有正则表达式的数组

Question

I have some strings that look like arrays which I'd like to make into real arrays

For example this string...

"['str1', 'str2', 'str3', 'str4']"

...I'd like to become and array of strings:

['str1','str2','str3','str4']

I think what I'd need to do is run a RegExp on the string to get rid of the brackets ([]), single quotes (') and spaces so its just a string like: "str1,str2,str3,str4" and then simply run the split(',') method but I'm not sure how to make this RegExp

Answer 1

Simplest way is to use JSON.parse . Strings inside JSON string have to be delimited by double quotes, like this.

result = JSON.parse('["str1", "str2", "str3", "str4"]'); 

This technique will work for null , any javascript object or any valid JSON object. You can read about JSON format here:

Don't reinvent the wheel! Don't use custom regexes for solved problem.
