Help needed to get information across forms with javascript

[DDragon]

ok here is the problem, i have to forms which have values i wish to be added together i can add together the values in one form all right but im having problems with adding the values of the other form to it... ill post the code for you to look at and try to explaine in detail what im trying to do.

here is the code (HTML and Javascript so you get the whole picture):

Javascript:

var gen, lights;

var lammount;



function validatetheform()
	{
		if (!document.frmTorder.txtBname.value)
			{
				alert("Please enter your buisness name.");
				document.frmTorder.txtBname.focus();
			}

		else if(!document.frmTorder.txtBaddy.value)
			{
				alert("Please enter you Buisness address.");
				document.frmTorder.txtBaddy.focus();
			}

		else if(!document.frmTorder.txtPcode.value)
			{
				alert("Plese enter your postcode");
				document.frmTorder.txtPcode.focus();
			}

		else if(!document.frmTorder.txtState.value)
			{
				alert("Please enter you state.");
				document.frmTorder.txtState.focus();
			}

		else if(!document.frmTorder.txtSite.value)
			{
				alert("Please enter the event address.");
				document.frmTorder.txtSite.focus();
			}

		return true;
	}


function total_add()
	{

		var bubbleday, simday, slideday, bungiesday;
		var bubble, sim, slide, bungies;
		var bubblet, simt, slidet, bungiest;

		var total;

		// Setting the value for the days
		bubbleday = document.frmTorder.txtBubbledays.value;
		simday = document.frmTorder.txtSimdays.value;
		slideday = document.frmTorder.txtSlidedays.value;
		bungiesday = document.frmTorder.txtBungiedays.value;

		// setting the value for the set price
		bubble = document.frmTorder.txtBubbleprice.value;
		sim = document.frmTorder.txtSimprice.value;
		slide = document.frmTorder.txtSlideprice.value;
		bungies = document.frmTorder.txtBungieprice.value;

		// calculating the total of the individual rides
		bungiest = bungies * bungiesday;
		simt = sim * simday;
		slidet = slide * slideday;
		bubblet = bubble * bubbleday;

		// setting the value total with the ammounts from the rides
		total = bubblet + slidet + simt + bungiest;

		document.frmTorder.txtTotalprice.value = total;

	}



function extras()

	{
		if (document.frmExtras.chkGen = selected)

			{

				gen = document.frmExtras.txtGenprice.value;

			}



		alert("Gen amount is: " + gen);
	
	}

Now what i need is to be able to get the values of 'frmExtras' into the box 'txtTotalprice' if the check box for 'chkGen' is selected or an ammount from 'txtLprice' if 'txtLammount' has a value in it.. ive been trying to nut it out and my own knowledge is just too limited i need help with it... any advice of how to go about it would be great.

appologies, but it would have been better to send me a pm stating you changed the topic rather than do it in the thread as i didnt know what had happend to my thread so i reposted. just a thought

To find your threads, see the subscribed link or the Started link (top of the page).

If you want to refer to the form, use document.forms["frmExtras"].elements[elementName]. To check that chkGen is checked:
[code=javascript]if (document.forms["frmExtras"].elements["chkGen"].checked) {
...
}[/code] To check that txtlAmmount has a value, just check that it isn't equal to empty (!= "").

Thanks for the help acoder, and to respond to your first post i did that but still a pm would be helpful instead of just changing it and making it a post in the thread.

True, a PM would work if everyone knew how to use them. Many simply don't know they exist.

in case you did you could have seen the change ... and since a thread title 'Help Needed' is not a title where somebody knows what you mean ... remember: nearly all threads in the programming forums are started to solve a problem and thus they are asking for help ... i changed it according to the posting guidelines ... since you only have 2 started threads i cannot imagine that you couldn't have noticed the change without a PM ... but i'll try to remember you and in case the same issue occurs i'll send you a PM regarding the change ...

kind regards

Gits, dont take me wrong i ment no offence by my comments it just struck me as odd that i didnt get a pm about it thats all... and i understand the reasons behind changing the topic and i do mean my apology i gave about it. it just confused me where it went thats all as ive only posted here once before (thread wise). I thank you for your understanding with this i will be using the standard for my posts from now on so this situation should not happen again.

Thanks again,

If you want to refer to the form, use document.forms["frmExtras"].elements[elementName]. To check that chkGen is checked:
[code=javascript]if (document.forms["frmExtras"].elements["chkGen"].checked) {
...
}[/code] To check that txtlAmmount has a value, just check that it isn't equal to empty (!= "").

so if i replace my 'if' statements in the script regarding the Extras form it should work in Theory?

DD

(That is true about people not knowing how to use the PM service)

[gits]

no problem ... i just wanted to avoid a discussion between you and acoder concerning that small issue ... usually i don't pm a user unless its an important thing where i want to assure he knows about ...

anyway ... just post back to the forum anytime you have more questions :) ... and now i know that you love to have PMs :) ...

kind regards

[acoder]

It's the extras() function that needs changing. If you change it to what I've suggested, it should work or at least the first bit. You mentioned about the hidden variable having a value. That should probably go as an else if, e.g.
[code=javascript]if (...checked) {
// set total
} else if (...value != "") {
// set total value using hidden variable value
}[/code]
