如何将String转换为数组，并在Javascript中删除引号？

Question

I want to convert the following String to an array:

str = " ['GHR',  15, 14    ], ['GHR',  12, 20  ] ";
array = new Array (str);

when I do : console.log(array );

it gives me: [" ['GHR', 15, 14 ], ['GHR', 12, 20 ] "] ,

but I want the result without quotation marks like:

[['GHR', 15, 14 ], ['GHR', 12, 20 ]]

Kindly, how to remove only the first and last quotation marks from the beginning and the end of the array? I'm using this method to get data from mongodatabse then convert the results to rows that google charts can read them, in Metero platform

Answer 1

You can use JSON.parse which will require you to swap out the single quotes

var str = " ['GHR',  15, 14    ], ['GHR',  12, 20  ] ";
var arr = JSON.parse("[" + str.replace(/'/g,'"') + "]");

or you can use new Function

var str = " ['GHR',  15, 14    ], ['GHR',  12, 20  ] ";
var arr = (new Function( "return [" + str + "]")());

Or get whatever is outputting it to make an array to start with or make it valid JSON so it can be parsed correctly.

Try below

 var str = " ['GHR', 15, 14 ], ['GHR', 12, 20 ] "; str = str.replace(/\\s+/g, ' '); var arr = str.split('],').join(']|').split('|'); console.log(arr);
