extract information from a JavaScript array using regular expressions

Question

extract information from a JavaScript array using regular expressions

After struggling for hours, I decided to seek assistance from the stackoverflow community. While I understand that regex could solve my problem, I lack the necessary expertise and time to learn before my deadline.

The challenge lies in extracting the 6-digit code following the &PG=. Although I managed to piece together a regex in Chrome's console to capture the entire &PG=XXXXXX string, the browser crashed, and I lost the expression. My goal is to retrieve 'SPTRF3,SPTRF1,SPTRF4,SPTHP4' from the given array, either in a new array or as a string.

Any assistance offered would be immensely appreciated!

Answer 1

Answer №1

What is the significance of regular expressions? One alternative could be employing a substring function on the string located in the array: .substr(3).

Assuming that the "&PG=" string consistently appears in the array at position 2, you can cycle through the array of arrays using the following method:

for (index in myArray)
   console.log(myArray[index][2].substr(4), ",");

Iterate through an array using a for loop and extract specific information using regex capture groups. Store the extracted data in a new array called products.

var products = []
for (var i=0, l=arr.length, p; i<l; i++){
  p = /&PG\=(.+)/.exec(arr[i])[1]
  if (p) products.push(p)
}
