JavaScript - Bmi Calculator - Novice Cannot Get It Working!
Hello
I have been asked by a friend to put together a BMI calculator. I know there are javascript ones already out there that I could use the code for, but a) it needs to do a specific thing b) I am interested in learning a bit of jscript - hence why I just spent about 4hrs trying to get it working You can see what I have been working on here http://www.kubedp.co.uk/bmi2.html Basically - what it needs to do is the following :- - User can either enter Feet/Inches or centimeters for height - User can either enter Stones/Pounds or Kilos for weight. - If they enter Feeet/Inches and centimeters - it throws an error (similar thing for weight). It then outputs the BMI to txtBMIResults. I managed to get the validation working on not having both Stones/Pounds and Kilos filled in etc, but when it comes to the actual calculation - I am stumped. If someone could look at this for me and hopefully code it and comment it so I can understand what has been done to get it working so I might learn, that would be fantastic. http://www.bmi-calculator.net/bmi-formula.php Is the formulas for calculating BMI. Not sure if you can tell from the code - but I was trying to get it so that the calculation was always done on Kilos and Meters, so I was taking the Stones and Pounds and feet and inches and trying to convert it to kilos and metres and then run the calculation. Hope I have been clear. Many thanks for any help anyone can offer Similar TutorialsGreetings all, I am excited to have found this website as I have been trying to implement an idea for a website for about a month, but with little success. My problem is that I have little coding experience/knowledge. I am trying to create a form/calculator. My concept includes drop down menus, check boxes, roll over images, and calculations. I've been trying to do the coding in Microsoft Excel; however, this has been very cumbersome, and the look is very generic. The reason for my post here is I was hoping someone could offer advice, for a novice, on the best way to accomplish what I am looking to do. Is there a software/program that would be helpful with the coding? Am I in over my head? Thank you all for any help you can offer! Josh I have attempted several variations of this, none of which seem to help. I have narrowed this down to being the central problem at hand. Do i just have something out of place? Code:
if (monthly_pay>=1000)
{bank_account="Okay";}
else if ((monthly_pay>=700)&&(monthly_pay<=999))
{bank_account="Still Okay";}
else if ((monthly_pay>=500)&&(monthly_pay<=699))
{bank_account="Start to worry";}
else if ((monthly_pay>=300)&&(monthly_pay<=499))
{bank_account="Panic";}
else if (monthly_pay<=299)
{bank_account="Chapter 9";}
else
{document.write("Marry Up")}
}
Optionally, could I not do else if and somehow use this as a Nested If? Any help appreciated, Thank You I am working on an Mpg calculator and I am stuck any input would be greatly appreciated. Code:

Thank you in advance. Evening all A complete novice here who is trying to learn a bit about web development on a basic level. Ive kind of got my head round basic html and css, and i mean basic but its working for me and thats all i need for now What i've been trying to do is incorporate some javascript into my demo site to make it a bit more dynamic and have found some code that looks like what i need (simple slideshow) but i cant get a result the code i found allegedly just drops in amongst the index html where required and works. Trouble is if i try and save my index html to preview i cant save the file as html as it reverts to a standard text file. I tried to create an external .js file and link it to my html with no success. I appreciate it sub entry level stuff here but im stuck. source of code http://www.javascriptkit.com/script/...bleslide.shtml i want the above to drop into a div in my site. do i need anything within the head tags etc Thanks Dave I am writing a Javascript to validate a web page form for a intro-to programming class. i have written the same type of page for the homework and it worked fine. and in midterm it worked fine. now when i hit submit on the this form nothing happens. Does any one have any debugging ideas or recommend tools for debugging.
Hi everyone, I'm not sure I'm posting this correctly (or if anyone is actually willing to help me out ) but I'm looking for the javascript code to create the following comparative image gallery. http://i528.photobucket.com/albums/d...evised-RBA.jpg Basically the image gallery needs to do the following. When I click on an image (small grey boxes on the bottom), that specific image will appear in the first window. When I click on another image, it will appear in the second window. And finally, click on one more image so that it appears in the third window. If I want to remove one of the images from the large window, I want to do so by clicking the clear button underneath the image I want to remove. If anyone could help me out with this, I would be EXTREMELY grateful! Hello, So all I need to do is have a checkbox above the 'submit' button that the user must check before the button becomes active. Once the user checks the checkbox, then the button becomes active - and users can click on this button to get to the new page. However, I haven't found any tutorials online that handle this exactly. What I have found is example scripts that have multiple checkboxes, etc...and if I try to remove any of them from the script, it seems to mess up the functionality. So - take this for example. This would actually work perfect, if the male/female option wasn't there, and the 'reset' wasn't there either: Quote: <head> <script type="text/javascript"> function validate(form) { // Checking if at least one period button is selected. Or not. if (!document.form1.sex[0].checked && !document.form1.sex[1].checked){ alert("Please Select Sex"); return false;} if(!document.form1.agree.checked){alert("Please check the terms and conditions"); return false; } return true; } </script> </head> <body> <table border='0' width='50%' cellspacing='0' cellpadding='0' ><form name=form1 method=post action=action_page.php onsubmit='return validate(this)'><input type=hidden name=todo value=post> <tr bgcolor='#ffffff'><td align=center ><font face='verdana' size='2'><b>Sex</b><input type=radio name=sex value='male'>Male </font><input type=radio name=sex value='female'><font face='verdana' size='2'>Female</font></td></tr> <tr><td align=center bgcolor='#f1f1f1'><font face='verdana' size='2'><input type=checkbox name=agree value='yes'>I agree to terms and conditions </td></tr> <tr bgcolor='#ffffff'><td align=center ><input type=submit value=Submit> <input type=reset value=Reset></td></tr> </table> </body> I try to manually remove the 'male/female' options for this in Dreamweaver, but then the script doesn't work properly. Can anybody help me out here? Would be greatly appreciated. Thank you Hi I have spent some time writing a javascript online calculator. The calculator works on Safari and Firefox but not on IE or Opera. I am sure there are multiple errors in the code but have gone as far as my limited self taught experience will take me. Any help will be greatly appreciated! Here's the code I have put together.

Specifically, the form has a field for a district number, and I need to set it up so that if a certain district number is entered, the form submission gets emailed to a specified email address. I'm not trying to make it an email-only form - the results have to be posted in an output file as well. I've tried googling for an answer but haven't found anything that answers my question. Maybe that's because I don't know enough javascript to understand the answers. Can anyone help?? Thanks! I am not sure if I am in the right section. I tried to search this but couldn't find what I needed. I am very limited on my javascript knowledge. I need a video player that functions almost exactly like the one in this example: http://www.popcap.com/games/bookworm...L_1_8_19_08_en {the links that toggle between the video and flash slideshow depending on which is clicked. The player showing the videos and screenshots for the game}. I tried looking at the source to understand the functions, but my code is not working. I know the player is calling some javascript, but I'm not sure I understand it all. Can someone explain to me the basic functioning of this player as shown? I would very much appreciate it.

ANY help is GREATLY appreciated! Hi all master and expert coders I am working on a calculator which using the instructor's codes from the school. The problem that I having right now is the operator. I have successfully complete only the addition, but could not manage on subtraction and the rest operator. I hope experienced codes would help me out on this.

The problem i'm having is that the webpage is moving to a hosting company that doesn't support asp. I'm wanting to rebuild the calculator in javascript, however I have no javascript experience. I can figure some parts of the code out, however I don't really have time to learn it, and was wondering if someone would be willing to help. The site i'm trying to change is: http://sunflowertitle.com/ratecalculator.aspx It shouldn't be that difficult to rebuild as its not a detailed calculator. I have all the original files if anyone needs them, i've been working on this for awhile and i'm to the point i'd be willing to pay someone to build it. |
