Javascript headache?

Question

i want to alert the user if they enter any number over 50.

how do i get it to work...want am i doing wrong.


if (document.form1.textfield.value = > 50)
alert("please enter number lower than 50")

Answer 1

Hmm, things have apparently changed in the past few versions of Javascript. It used to be you couldn't do an mathematical operation straight from a form element.

Anyways, the comparison operator that you should use is

>=

not

=>

.

Answer 2

function Validate(){
if(form1.textfieldID.value>50){
alert("please enter number lower than 50")
}
}




Note that said by m.trojahn
is only limiting users from typing over 50 character in a textbox, not validating a value that is less than 50

Answer 3

easier way is just set the field maxlenght to 50, so u don't even need to handle the input size:
