I have a string
var myString = "['Item', 'Count'],['iPad',2],['Android',1]";
I need to convert it into an array where:
myArray[0][0] = 'Item';
myArray[0][1] = 'Count';
myArray[1][0] = 'iPad';
myArray[1][1] = 2;
etc...
The string can vary in length but will always be in the format above. I have tried splitting and splicing and any other "ing" I can think of but I can't get it.
Can anyone help please?
If the string is certain to be secure, the simplest would be to concatenat [ and ] to the beginning and end, and then eval it.
var arr = eval("[" + myString + "]");
If you wanted greater safety, use double quotes for your strings, and use JSON.parse() in the same way.
var myString = '["Item", "Count"],["iPad",2],["Android",1]';
var arr = JSON.parse("[" + myString + "]");
This will limit you to supported JSON data types, but given your example string, it'll work fine.
eval is dangerous, you should not use it on any content that the user can interact with in any way!write your code like
var myString = "[['Item', 'Count'],['iPad',2],['Android',1]]";
and just
var arr = eval(myString);
try this :
JSON.parse("[['Item', 'Count'],['iPad',2],['Android',1]]".replace(/\'/g,"\""))
I tried to use eval, but in my case it doens't work... My need is convert a string into a array of objects. This is my string (a ajax request result):
{'printjob':{'bill_id':7998,'product_ids':[23703,23704,23705]}}
when I try:
x = "{'printjob':{'bill_id':7998,'product_ids':[23703,23704,23705]}}";
eval(x);
I receive a "Unexpected token :" error.
My solution was:
x = "{'printjob':{'bill_id':7998,'product_ids':[23703,23704,23705]}}";
x = "temp = " + x + "; return temp;"
tempFunction = new Function (x);
finalArray = tempFunction();
now a have the object finalArray!
I hope to help
new Function(string) is just as dangerous as eval, make sure that a user cannot change any attributes within the Object`.
