javascript

var.replace is not a function

I'm using the below code to try to trim the string in Javascript but am getting the error mentioned in the title:

function trim(str) {
    return str.replace(/^\s+|\s+$/g,'');
}

Edit:

I fixed the problem.... sorry I should have put the code on how I was calling it too.... realized I accidentally was passing the object of the form field itself rather than its value.

Solution

  • My guess is that the code that's calling your trim function is not actually passing a string to it.

    To fix this, you can make str a string, like this: str.toString().replace(...)
    ...as alper pointed out below.
