I have a string "$1,285.00" to convert into number by using javascript

Question

I would like to convert a string "$1,258.98" into a number 1258.98. How to use JavaScript to achieve this purpose?

Answer 1

1. Simply replace $ and , in the string with empty string and then use parseFloat function to convert it to a valid floating point number.

   var data = "$1,258.98";
   console.log(parseFloat(data.replace("$", "").replace(",", "")));
   

2. Or replace just the , and then ignore the first character with substring(1) like this

   console.log(parseFloat(data.replace(",", "").substring(1)));
   

3. Or you can use regular expression, to replace $ and ,, like this

   console.log(parseFloat(data.replace(/[$,]/g, "")));
   

Output

1258.98
