“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?
