Hey people,
I have this follwing HTML file, and it displays fine but it is supposed to clear the form if I only input one or none of the fields, the webserver is a fake address in the ACTION attribute of the form, but it is supposed to show that if not all the fields are entered then the form is supposed to clear itself, have I done something wrong.
remember, I am just learning JavaScript.

Davy
p.s. some words may not be spelled correctly as it cannot be included in this site.

How simple does it have to be???

Don't forget your semicolons!

Tom,
semicolons in JavaScript mean nothing at all! It is good practice to use them, but the script works the same with or without them!

Haha, you know how long it took me to realize this? Well, I'm not going to answer for fear of embarassment/banishment from the Ranch forever. Javascript is such an interesting creature...I've often done things which were in complete opposition to standard programming practice.
Go ahead and throw some strings in the pot, then some floats and maybe some arrays...stir it up and the sit back at watch code that has no business working anywhere else in the programming world, run like a charm.

for (int i = today; i < endOfTime; i++) { code(); }

hey thanks for the reply,
Tom, I already know about the semicolons, Eric helped me out on this a few weeks ago, but thanks anyway.
Eric


if(thisform.u_nameval.value.length > 0 && thisform.pwd.value.length > 0)


I noticed that i can also do it like:
if(thisform.u_name.value.length > 0 && thisform.pwd.value.length > 0)
what is the difference taking out the val after name??? thanks for helping to make it work.
I forgot about the & being bitwise and && being logical!!! silly me

without the name you are calling the object. A browser like IE will usuually figure out what you mean, other browsers will error out.

with the object you have a lot of other attributes you can call: style, name, title, etc...

Hi Eric,
I am not sure I got you correctly, or maybe I did not explain my self clearly
if(thisform.u_nameval.value.length > 0 && thisform.pwd.value.length > 0)
I have bolded the part which I was talking about.
My browser is firefox v0.8 and the bold part included or not works fine, so what is the bold part dooing?
