Can someone explain to me how I should code to calculate this?
I want to let the user add 4 different numbers (this is done) and then I want to + these numbers with each other.
This is the code I got: var medel = tal1+tal2+tal3+tal4 ;
Let say the user enters 1+2+3+4. Then the result should be 10. But I get this number as result: 1234
What have I done wrong?
I am new to using Javascript and have been trying to incorporate this equation into my if statement but cannot get it to calculate properly no matter which method I use. Here is the function as I have it worked out presently.
[Code]...
I can't seem to get the math function to calculate and display properly. Can anyone point me in the right direction.
Here is my code.
For my links I have two portions. The first is the regular href for people that don't have javascript can navigate the site and the next an onclick for those with javascript can load pages inline with transitions and have it stay in their history for Firefox. All a la that wonderful ajax stuff everyone knows about by now.
It seemed like a good idea at the time...
Because it is stored in the #hash value these people can link another person that has javascript enabled as well to the page and have the page load. But that's it. So we have 96% some odd percent of users included.
There is going to be confusion that happens if someone sends a link to someone without javascript, since it will just load the home page.
From what I have researched.. the server doesn't pick up the #hash value (this is obvious since when you click on a link that's linking to a spot in the page, it's the browser doing the work). That's okay, the thing I want anyway is for it to pick up on the very first request via well.. something. The first request is when the server does do something and may have a chance to do something with a hash value.
So questions:
1. Can I manipulate the server into 'reading' this #hash value on the initial request and then put it through say.. php or mod_rewrite?
2. What about css.. this is another client end thing that could work, but I am completely lost when it comes to css and recognising hash values. Even if it just works for Firefox/MSIE/Opera.. well.. that's something as it's non-intrusive and ups the people that can access my site properly.
There is an option to post a noscript tag to notify users on the first load that their javascript is off.. but there's no way for php to also be smart and say "hey, there's a Hash value"... as it could, I would just load the page that way. Code:
I want to add onto my ebay auction a calculation which would show the unit price of a box of 5 electrical sockets.
So say it is currently on auction at £5.62 and I charge £1.99 Postage & packing thats a total of £7.61 with a unit price of £1.52. Then £1.52 is the figure I want to output and show on screen.
I'm just starting out in JS and would like to know how to solve this.
I have an HTML form with 3 checkboxes, like a would-be order form. For example, on checkbox 1, the product is a toy car that costs $5.00, second box is a cigar cutter for $50, etc. I to have a button that when clicked, enters the total price (no taxes or subtotals) into a textbox field below in the same page.
If I detect an empty textbox, I fill it with a value ('Dad'). If I do this twice, the second time around IE 6 fails to notice that I've cleared the textbox again, thus leaving the textbox cleared. Is there a recommended workaround? Opera 7.23 is detecting the second deletion fine.
View 3 Replies View RelatedThe purpose of my application is to require a website visitor to complete
a form before participating in a search application. I have a specific
reason for doing this with client-side javascript, but I'm not going to
go into the explanation of "why."
Ideally, the visitor goes to http://www.hopelandinc.com/golf-homes.html.
If they haven't registered in 90 days, they'll be redirected to a
registration form. Once they complete the reg form, they'll have a cookie
set (called "isRegistered") and be taken back to the golf homes page.
For testing purposes, it is not necessary to actually complete the form.
You can go to the golf-homes.html page, which will set the regReturn
cookie, and then bypass the form submission by going directly to
http://hopelandinc.com/registration-thanks.html
In short, it ain't working. (IE 6 test).
golf-homes.html calls the function securePage() below, which sets
regReturn and redirects to search-registration.html.
search-registration is a form that posts to an ASP script, then redirects
to registration-thanks.html
registration-thanks.html calls the function addRegistrationCookie which
adds the isRegisteredCookie, and then redirects to the value stored in
regReturn.
I've been trying to figure out why it doesn't work all day, and can't
find the problem. Hopefully some super-genius here will be able to help!
Here is the function I'm using to retrieve a cookie value ("regReturn")
and redirect to a specified web page:
I'm running this line of code:
oTarget.pasteHTML(formattedHtmlText);
where oTarget is a text range object.
When formattedHtmlText is, say, "<STRONG><BUTTON
class=placeHolder>[[ContAmt]]</BUTTON> text</STRONG>" the HTML is
pasted properly and the UI is changed accordingly.
However, if formattedHtmlText is "<BUTTON
class=placeHolder>[[ContAmt]]</BUTTON> text" the HTML is not
pasted and there is no change in the UI.
I have a problem where I have to use jQuery.noconflict(), but I have no idea how to use it properly.I'm working with some richfaces elements which uses the richfaces jQuery version and the countdown plugin from keith-wood.name/countdown.html which need another jQuery plugin.If I include the files for the coundown, the countdown works but the modalPanels didn't and vice versa.

i looked in one of my other projects that i recently finished, and the code seems to be identical.Basically it should generate an array of Canvases where individual letters can be written. Later other javascript code will try to determine which letter was written (letter recognition).The error that i keep getting is "ChangeThisID is Null".

Here's something that I tested without the PHP and it worked ok. Now that I've introduced the PHP to the document it doesn't work. The PHP variable is not passing to Javascript properly. By use of some cleverly placed alert boxes, I figured out that the only thing that is getting passed forward is something called : "object HTML ImageElement"
Specifically, I assign the element ID the unique ID number of the record in the SQL database. The problem isn't with the ID numbers themselves: They are alphanumeric and unique.I think it boils down to one of two lines of code. Either this isn't working (about line 12)
function expander(RecordID){
or perhaps it is when I am calling the function (about line 66):
echo "<img id='".$row['IDNumber']."' src=".$row['ImagePath']." width='5%' onMouseOver='expander(".$row['IDNumber'].");' onMouseOut='shrinker(".$row['IDNumber'].");'>";}
The PHP works (I can get the images to appear, so the connection to SQL and such isn't a problem). I am sure most of the JavaScript is good, too, as I said I had it all working prior to dropping in the PHP.Since I am not going from JavaScript to PHP I don't think I need AJAX. I just need the PHP to pass to JavaScript.

I have quite a complex form, for me anyway. The form is meant to submit, use checkForm to see if the fields all pass the validation and then submit and run the PHP script to send the emails. Now, it is sending the emails and the validation works but it is not redirecting to $NextURL like it should.
if$(edtApplicantAge){} is supposed to set $NextURL when the page first loads as $edtApplicantAge is taken from POST information submitted via the previous form. I have echoed this and when it first lands on the page the age does show up.
$edtEmail and $edtAge are actions for the two forms on my page. I have only put one on as I dont want to flood my post with code. If anyone could see something thats missing id be so grateful. I spent hours yesterday and just couldnt figure it. Ive got this working in 3 other variations yet can't figure out where im going wrong on this one.
I am having two divs with ids nav and navLinks, that contain unordered lists of hyper links. I am calling a onload function named displayID that accepts div's id as a argument/parameter (nav and navLinks) twice with different parameters. the function is firing only once with the parameter that i first specify, even though i call the function twice. Am i doing anything wrong in calling the same function twice with different parameters? Code:

Here is my code (it is in a phpBB3 page) code...
On a normal HTML page it works, so I'm stumped
If anyone knows what could be going on here, or knows of another simple countdown script
I believe that this has been answered somewhere but I cannot find it. I have 51 textboxes on page. In 50 I can enter value. 51st should tell me what is average of entered numbers.
As user types I want script to iterate trough form count and sum non-empty fields and than divides this two numbers.I need to sum values from fields that have value (not emty fields) and to divide this number by number of non empty fields. This should occur on every change in any of those 50 textboxes so to have live preview of average.
I'm really new to JS and I don't know even how to sum these numbers.

In the second page he need to choose the time he want for his appointment (the time is in GMT+3 -> my local time). in this page the script also get the time zone and the date that he choose in the previous page (using POST - PHP). the date saved in variable. I used unix time (MKTIME function) I want that every time my visitor choose time (from drop-down box) a new cell/DIV will appear with his local time.for example - when he choose date: 10 May 2010, time zone: Austrlia - East Coast (+8 Hours) and time 22:00, New DIV will appear with the date "11 May 2010, 03:00AM" (there are 5 hours different).what is the JS what caculate and show the visitor local time?(I have, in PHP, only his time zone and the date that he coose in the first page)

I'm working on creating a custom calculator to determine the amount of money / credits users may earn from referrals. I've tested onChange, and it will work only when I have changed to a new field or clicked off that field. How do I make this calculate live?
So if the current value is 5 and I change it to 6, it will automatically recalculate the new value.
You can see what I'm working on here:

Note: The one I'm testing is the 1st Level field. For now i'm just having it display the date.
I am making what I call a PM (Preventive Maintenance) Kit list. My users will use this list to generate a printable sheet to tell me what they used out of there kit. The list includes pricing per part and I would like the list to calculate the costing as they enter each item. So a total per line and an overall total cost.
I have included a snap shot of the page and below is the code. I can do this sort of thing on a small scale with just adding two lines but I am not sure how to modify it to handle this scale. You can see the script towards the bottom of the page. That is my lame attempt to make the per line costing happen but NOTHING happens.

View 3 Replies View RelatedI have 3 textbox controls on my web page that are numeric currency fields in which a user can enter a numeric value, either positive or negative into TB1 and TB2 (both of these fields go thru edit checks to make sure a numeric value is entered and then return a currency value ie; $2500.00). TB3 is calculated resulting in TB3 = TB1 (($6500)) - TB2 ($2500).
My problem is that if a user enters a negative value for TB1, it returns a "NaN" and the value in TB3 turns out to be the same value as in TB2. Essentialy the calulation ends up being 0 - 2500 = 2500 (see screenshot). I've attached 2 functions below.
Code:
function cal_Overage_Shortage() {
