How to remove all non-numeric characters from a variable

rated 0 times [ 57] [ 5] / answers: 1 / hits: 17695 / 9 Years ago, fri, february 20, 2015, 12:00:00

How can I remove all text characters (not numbers or float) from a javascript variable ?

function deduct(){

    var getamt= document.getElementById('cf').value; //eg: Amount is 1000

    var value1 = 100;

    var getamt2 = (value1-getamt);

    document.getElementById('rf').value=getamt2;

}

I want getamt as number. parseInt is giving NaN result.

Use regular expression like this:

var getamt= document.getElementById('cf').value; //eg: Amount is 1000

var value1 = 100;

var getamt2 = value1 - getamt.replace( /D+/g, ''); // this replaces all non-number characters in the string with nothing.

console.log(getamt2);
