Add Numbers In Text Boxes To Total In A Quantity Text Box?
Aug 6, 2010
how to add up a series of text boxes which contain numbers that a user will input and have the total of those text boxes show up in a quantity text box on the next page.
Not sure if i should use javascript or php, but i don't know how to do it either
in my webpage, i've a form which contains several textboxes and a submit button. all the textboxes are generated using php looping method.so, what i wanna do is, when user click the submit button, it will sum up all the textboxes values and pop up alert message telling the total value.
I am trying to simulate a simple checkout page where a user inputs the quantity of merchandise that they want in multiple text boxes. When they click "calculate" it calculates the subtotal, tax, and total. As it stands my calculate function works if I do quantity * price for each text box and then add together. I would have to do this 9 times! :eek: I would like to use an array but I am not exactly sure how to use it to do calculations. I know I need a loop (which I have written) and an array (which is written also).
I'm primarily a database programmer (Mysql and PHP) but I have some Javascript programming and I have been programming in other languages for over 25 years.
On to my problem:
I'm trying the create a function in Javascript which will take a variable from three different text boxes and show the net result in a fourth text box that is ReadOnly. This is all on the same page. All three text boxes have other Javascript scripts formatting the value in the text boxes.
My requirement is to develop a simple form with checkboxes which when selected calculate a price based on the value assigned to the checkbox. The form and calculations is working great but i need a few final touches which i can't work out.
1. I want the total to be in plain text and not in a text box maybe just drop the total value in a DIV.
2. I want the form to start with a default value for example 200, i have tried adding a hidden checkbox with a value of 200 and setting it to checked as default but it doesnt display 200 in the total when i first load the page it only calculates it when i select the first box and i need it to be displayed as the total even if no options are selected.
I've been given this ridiculous assignment where I have to create a shopping web page.finding the javascript codes that will allow the user to update their total as they enter the quantities of the different products in the assigned text boxes.I don't even know where to start because we were never taught how to do this in class!
I am trying to add a spin control to my quantity field before i add the ordered quantity to a shop cart array. The way its set up at the moment if you click the deincrement arrow it actually goes into negative numbers. (no good coz people cant order a negative number eh#$@#$@) This the
<head> Code <!---sPIN BUTTONS TO UP QUANTITY---> <script type="text/javascript"> function changeVal(n) { document.forms[0].quantity.value =parseInt(document.forms[0].quantity.value) + n; } </script> [Code]
Below is the code I use to populate a textboxes (compaddress) when I select the compname from the dropdown. I would like to be able to populate other textboxes such as the compdescription, compmaincontact and others when I select the compname from the dropdown. I think that I need an array but I really would like some advice on how to do it as all of my attempts have failed so far
Firstly, I got this script which gets values and automatically calculates it and shows result. Script: <script type="text/javascript"> function calculate(f){ var prod=Number(f['users'].value); var quan=Number(f['months'].value); var tot=prod*quan; f['total'].value=tot==0?'':tot.toFixed(2); } </script> <ul><li class="bold">Users</li> <li> <select name="users" onchange="calculate(this.form)" id="users"> <option value='1'>1</option> <option value='2'>2</option> </select> </li></ul> <ul><li class="bold">Period</li><li> <select name="months" onchange="calculate(this.form)" id="months"> <option value=''>Select Months</option> <option value='1'>1 Month</option> <option value='2'>2 Months</option> </select></li></ul> Total: <input type="text" name="total" readonly="readonly">
What I'm trying to make is, the total, to be in a div and not input type text Something like <div id="total"></div> I don't like because it shows in form, I want it directly. One more thing, is possible to make the default price 0.00 ? and when selecting automatically changes to price..
I looked around for a solution but could not find one. I am trying to find combinations of numbers that can add up to a total. The numbers available and the total are different each time.
For example, I have an array that contains the following numbers: [16,12,8,6,4,2] I want to find the combinations that add up to 140, like this:
I have two drop down menus. I want two values to be added based on what they picked and then outputted to a text field to show a grand total in a dollar amount.
This is what I have:
Code:
Code:
Note I haven't did any type of code for the 2nd drop down menu just in case anybody says I don't see anything. I was working on trying to get started in the right direction.
I want to select numbers from a list box and add it to a text box with comma separated. my java script code does not work into browser but work fine into eclipse jsp view.
function passingNumbersToTextArea(numToCall,allNum) { var numFromList=document.getElementById(allNum); var numToTextArea=document.getElementById(numToCall); if(numToTextArea.value.search(numFromList.value)!=-1)//if duplicate Number is exist { alert("Duplicate Number Can not be added :"); return false; } else { if(numToTextArea.value.length!=0) { // If textarea has value than it added another value with comma seperated numToTextArea.value=numToTextArea.value+','+numFromList.value; return false; } else { numToTextArea.value=numFromList.value; return false; } } }
javascript debugger shows error Error ``numToTextArea is null'' [x-] in file ``http://localhost:8888/SparkServiceProvisioningSystem/home.jsf'', line 21, character 0. Exception ``TypeError: numToTextArea is null'' thrown from function passingNumbersToTextArea(allNum=string:"allNumbers", numToCall=string:"numberToCall") in <http://localhost:8888/SparkServiceProvisioningSystem/home.jsf> line 21.

i want to use the jQuery UI Slider plugin in my website, however rather than using numbers i want to use 4 different options (easy, medium, hard, very hard), for the user to choose on the slider, how would i do this.
This is the slider i want to use jQuery UI Slider Snap to Increments
I have clear text, without html code. (in text area) and I want to take from this text numbers for every pertes. but, from attaquant is one var and for defenseur is second var, (every next line is own var too). But I don't know how to take this numbers,(in every next text like this, numbers is different).
This is text which I working on. Round : 1 Attaquant Serenity SR6 Total : 1 | Pertes : 0 (0%)
i have a multiple page form where on one page i ask my user to enter a number into a textbox. i would like to know how to get some textboxes to appear on the next page in relation to the number they enter on the first page. i.e. if they enter 10 in the first text box, 10 textboxes appear on the next page for them to enter data into and then press next to go onto the following page.
I have a table of textboxes which is dynamically create (based off the number of users and levels in my db). I want the sum of each row to be 100 - the easiest way to ensure this is to update the row sum after any change in the textboxes.The kicker is that I need to keep the user/level associations so that I can upload the new numbers to the database. Was thinking of using name="L5-U1" (level 5 - user 1) as the name attributes for each of the textboxes but unsure of how to sum the boxes using this method.After some further research, I think the best way is to assign the same class per row and add up all the textboxes in that class. What code would I use to auto-select the affiliated class? (e.g. I can't have a specific class listed in the function since they are dynamically generated, need to use "this" or pass the class name via onkeyup)
I made a form with text inputs but notice you can use special symbols. I want to only allo charaters like letters and numbers that is it.Is there any jquery function that cna do such a thing... if not how do you implement something that will filter it.
I have a database script that returns dates in the following format:
yyyy-mm-dd
I have been using the following code to change this format to dd-mm-yyyy:
<script type="text/javascript"> var myString = "[[date]]"; var mySplitResult = myString.split("-");document.write(mySplitResult[2] + "/" + mySplitResult[1] + "/" + mySplitResult[0] ); </script>
However, I now want to display the date in text format, e.g. 01-08-2009 would be displayed as 01 August 2009.how I change the script to show this format?
I know this is probably a real simple one, but I'm obviously missing something..
I'm building a function that I'll use throughout a website in the situation that I have two text boxes - the two text boxes will generally contain the same data. After the user completes the value of the first textbox, I want to onChange the value of the first textbox into the second textbox UNLESS the second textbox already has a value.
Here's what I've done so far...
IN THE HEAD function CopyTextBoxes(TextBox1,TextBox2) { if(TextBox2.value = '') { TextBox2.value = TextBox1.value} }
IN THE BODY WITHIN THE FORM <input name="MailFrom" type="text" id="MailFrom" size="60" maxlength="100" onChange="CopyTextBoxes('MailReplyTo','MailFrom')"> <input name="MailReplyTo" type="text" id="MailFrom" size="60" maxlength="100">
I'm trying to create a javascript function that will allow the user to press a button within the html code that will add a text box right above the button. If the user presses it a second time it should add a second text box right under the previous text box. Any ideas?
