With breaking a base64 string and assigning input fields

0

I have a very large base64 string and need to break there in multiplus up to 20 thousand characters not to errors when sending it via hidden field. Each broken piece will be sent in separate inputs and can not create the input via javascript, I will already have them in the fixed screen. About 4 inputs.

Exp: "data: image / png; base64, iVBORw0KGgoAAAANSUhEUgAAAWoAAAExCAYAAABVkejXA ..."

The simplest method I think is by REGEX. Using match :

var str = 'lorem Ipsum is simply dummy text of the printing and typesetting industry.

var matchs = str.match(/.{0,200}/g);

console.log(matchs);

Explanation

  • . will associate anything
  • {0,200} will search from 0 to 200, always trying the most
  • The match method will return a array with associations made.

OBS

I user {0,200} for demonstration, in your case just change to {0,20000} .
