Pass variable in document.getElementByid in javascript

Question

I have a variable account_number in which account number is stored. now i want to get the value of the element having id as account_number. How to do it in javascript ?

Answer 1

Are you storing just an integer as the element's id attribute? If so, browsers tend to behave in strange ways when looking for an element by an integer id. Try passing account_number.toString(), instead.

If that doesn't work, prepend something like "account_" to the beginning of your elements' id attributes and then call document.getElementById('account_' + account_number).value.
