ug....

im trying to desgin a new web ui for my hp mediavault and right now i am doing the javascript part of the ui.

heres my problem.
im putting a function in to erase the NVRAM, HOWEVER i dont want users to simply be able to click it and clear it without confirmation. i dont like the idea of a simple confirm() box becouse it would be too easy to click ok without thinkign about it, so i want to do this.

function conf()
{
var conf=prompt("WARNING really clear nvram? enter "understand" to continue.")
if (conf =="understand")
{
document.location.href="commandp/nvramclear.asp"
}
else
{
alert("invalid confirm code. ")
}
else if (conf ==null)
{
}
}


now, IF the user enters the confirm code wrong, i want the script to loop back to the top and keep on going until the user enters the correct code. HOWEVER, IF the user clicks cancel (and returns null) i want the script to stop.

i have yet to find a (good) way of doing this.

any ideas?

What's wrong with creating a while loop?

You could also use labels like:
top:
// Code here
// if bad command then
goto top;

you can use a goto command?

huh.... i thought of that, but i didn't think javascript had a goto command...

What about:

String temp;
do
{
temp=input.get();
}
while(!(temp.equals("understand")||temp.equals("") );
if(temp.equals("understand"))
{
nvram.clear();
}

Obviously, modify it to your needs.

ya, that works, I guess javascript doesn't have that goto command rrgh....

Remember don't declare your variable
String temp; // This doesn't work
var temp = new String(); // That's how I would do it but you don't need the 'new String() part it's just the c++ programmer in me :)

Also, with that code you can only type "understand" or else you are in an infinite loop.

ok, well here is my new code.
@star, one of the reasons i am doing this is so i can learn js, your post is a bit too advanced for what i am at now. i will save it however an look at it in a few days, when i can understand it a bit better. unfortunately, i only learned a little bit of js when i was younger, so now i am catching up.

here is my new code:
//this is a special function that prompts a confim code.
function conf()
{
do
{
var conf=prompt("WARNING really clear nvram? enter 'understand' to continue.")
if (conf =="understand")
{
document.location.href="commandp/nvramclear.asp"
}
else
{
alert("invalid confirm code.")
}
}
while (conf !="understand" && conf !=null)
}

the only problem with this is that it you exit, you get the alert message, but i think i can fix that on my own.

sorry for the double post, but i got it working now....

//this is a special function that prompts a confim code.
function conf()
{
do
{
var conf=prompt("WARNING really clear nvram? enter 'understand' to continue.")
if (conf =="understand")
{
document.location.href="commandp/nvramclear.asp"
}
else if (conf !=null)
{
alert("invalid confirm code.")
}
}
while (conf !="understand" && conf !=null)
}

all i added to get it to work was on line 11, i added on to else... with "if (conf !=null)

thanks to all who helped.

What if in the else statement you did something like:
else if(conf!=null)

Then you will not get that message.

true that. there were a few other ways i could have done it i think, but that popped into my head first.

now, i just have to code a js library to convert strings into human readable strings, but that shouldn't be hard at all....


chris

Clegs

Your strings aren't already human-readable?

Why don't you just change the strings in the code?

no, im talking about the strings generated by the device (im working on a new web ui for a embedded file server).


im talking mostly about little things. like for example, the server will generate dhcp_client when quired about the net mode, however, to look nice (and to be short) this needs ot be converted to just plain old "dhcp".

so, i create a variable in my js file that would read "var dhcp_client="dhcp"":)
