Description

From the above code in first text box i have been setting value of '1475g - 1500g' but i need to do is show only the weight numbers in two different input box

for example

string val = 1475g - 1500g;
string Separated_value1=1475;
string Separated_value2=1500;

CodePudding user response：

Use split and replace.

const input = document.querySelector("input").value; // add an ID or class or something, this is just for demo purposes

const [ seperated1, seperated2 ] = input.replace(/g/g, "").split(" - "); // First regular expression removes all "g"s from the string. Split turns the string into an array using " - " as a delimiter

console.log(seperated1, seperated2);

Use this:

let val = '1475g - 1500g';
val = val.replace(/g| /g, '');
val = val.split('-');
console.log(val[0], val[1]);
