“replace is not a function”

Question

I\'m trying to remove the comma from a number.

var thisbill_str = \"\"; 
thisbill = $(\'#linebill_\' + z).val(); 
if (isNaN(thisbill) ) { thisbill = 0.00; } 
thi         


        

Answer 1

TypeError: thisbill_str.replace is not a function

thisbill_str can't be coerced in to a String object, therefore it doesn't have the replace method.

Is the value of thisbill_str null?

Answer 2

thisbill_str = thisbill; 

You should be casting to a string here. thisbill_str is still a number, so it doesn't have a replace method.

thisbill_str = thisbill + '';

Answer 3

It is most likely caused by thisbill_str being something other than a String. Maybe you have some other code somewhere that automatically converts thisbill_str to a Number?

You can convert back to a string using String(thisbill_str).

The complete code would be:

thisbill = String(thisbill_str).replace(",", "")
