function checkForm(){
theform=document.custinfo
if ((theform.acode.value / theform.acode.value) != 1){
alert("Please enter your acode.")
theform.acode.focus()
return false;
}
if (theform.acode.length!=3){
alert("Please enter your acode.")
theform.acode.focus()
return false;
}
return true;
}
</SCRIPT> |
Hi. This is a java script app that checks a textfield called "acode" to make sure that it is a number[0-9] and that it contains only 3 characters... If i type a bunch of letters it returns with the error message like its supposed to .. However, no matter how many numbers i enter , it doesnt show the error code like its supposed to.. If i dont enter 3 numbers its supposed to show the error message.. But it doesnt do this.. Can anyone help?
Thanks |

Javascript has a way of deciding what type yout variables are for you... try changing
if (theform.acode.length!=3)
to
if ("G" + theform.acode.length!=4)
adding a character to the variable will ensure that it is treater as a string. I hope this works for you, and if it dosn't, you will never find a better Javascript help forum than:
