Javascript regex pattern without for money values without currency

Question

I was looking for a javascript regex pattern that will allow inserting or registering these type of amount

5
5.1
5.10
5
500,000
500,000.1
500,000.10

but these numbers should not be lesser than 0. I managed to find pattern but I want to omit the "$". All I want is numbers,commas,and dots only

var x = 5000;
var a = "5,000,000"
var y = "$5,,,000,000"
var z = "500,000"
var c = "c231"
console.log(x," Valid", /^\$?\d+(,\d{3})*(\.\d*)?$/.test(x))
console.log(a," Valid", /^\$?\d+(,\d{3})*(\.\d*)?$/.test(a))
console.log(y," Valid", /^\$?\d+(,\d{3})*(\.\d*)?$/.test(y))
console.log(z," Valid", /^\$?\d+(,\d{3})*(\.\d*)?$/.test(z))
console.log(c," Valid", /^\$?\d+(,\d{3})*(\.\d*)?$/.test(c))

Answer 1

Remove the \\$?

/^\\d+(,\\d{3})*(\\.\\d*)?$/

 var x = 5000; var a = "5,000,000" var y = "$5,,,000,000" var z = "500,000" var c = "c231" var d = "1...0.00" var e = "..." var f = "1.00,,," var validRegEx = /^\\d+(,\\d{3})*(\\.\\d*)?$/; console.log(x," Valid", validRegEx.test(x)) console.log(a," Valid", validRegEx.test(a)) console.log(y," Valid", validRegEx.test(y)) console.log(z," Valid", validRegEx.test(z)) console.log(c," Valid", validRegEx.test(c)) console.log(d," Valid", validRegEx.test(c)) console.log(e," Valid", validRegEx.test(c)) console.log(f," Valid", validRegEx.test(c)) 

Answer 2

Based on my Comment on Question the new code will be

var x = 5000;
var a = "5,000,000"
var y = "$5,,,000,000"
var z = "500,000"
var c = "c231"
console.log(x," Valid", /^\d+(,\d{3})*(\.\d*)?$/.test(x))
console.log(a," Valid", /^\d+(,\d{3})*(\.\d*)?$/.test(a))
console.log(y," Valid", /^\d+(,\d{3})*(\.\d*)?$/.test(y))
console.log(z," Valid", /^\d+(,\d{3})*(\.\d*)?$/.test(z))
console.log(c," Valid", /^\d+(,\d{3})*(\.\d*)?$/.test(c))
