Auto Sum Order Form Modification

Jul 14, 2010

I needed to calculate my prices on-the-fly and display it in textbox with javascript. Well I did succeed with values of radio button an checbox, but as I know very little javascript, I don't know how to expand the code I got from here: [URL].

How can I make this happen: I have a textbox:
HTML Code:
<input type="text" name="podstranice" size="19" class="podstr" onkeyup="this.form.total.value=calculateTotal(this);">
And when a user inputs a number in it, javascript multiplies it with some other number, say 10 (its a price*quantity thing) and adds it to the total price along with data from checkboxes and radio buttons. And so, this is my javascript. It is basically identical to one on the link, but you can view it better this way I think.

Code:
// Calculate the total for items in the form which are selected.
function calculateTotal(inputItem) {
with (inputItem.form) {
// Process each of the different input types in the form.
if (inputItem.type == "radio") {
// Process radio buttons .....

Update Order Form Without Page Refresh Modification

Feb 4, 2010

[URL]. I looked at this script and I tried playing around with it but could not figure out how to: Instead of having a check box field and then a radio box field, have 2 radio box fields, so the user picks from one group of radio boxes and then another. Then change the math behind it so the values in the first field are multiplied by 100 and then the values in the second field tack on a percentage (ex value in first field is 1.5 so 1.5x100 = 150 and value in second field is .5 so total is 225).

Form Posting To Itself Wipes Out Dom Modification When Redrawing Form

Jan 16, 2011

I have a webpage with a form inside it. Below the form is a div. When you submit the form it executes some javascript that adds a bunch of html to the div. I can step through the code in the Chrome debugger and see my dom changes are there, but disappear as I get to the original tags in the page. Is there anyway to prevent this?

Jquery :: Realtime Order Form - Change Form Elements Depending On Selection

Aug 25, 2010

I've been struggling trying to get a small order form to work the way I want it to. Here is a link to the live page: [URL] And here is the code in question:

[Code]...

I have two questions...

Question 1 How can I make this piece of script act a little smarter. Look at the order form, I'm catering for up to 4 people and providing lunch for them. If they select 3 people and the spaghetti bol for lunch, it's only adding $10 where it should be adding $30. Obviously this is simple multiplication but since the values in my form are prices it makes it a little tricky. I'm guessing an onselect on the first part of the form which changes the pricing of the other items would be the way to go, but how do I do this?

Question 2 The "Total Price" is placed before the <form> tag by the script. This is ok but it's not where I want it. How can I position this text elsewhere in the document?

Order Form Coding

Mar 13, 2006

I need advice about creating an order form (I was sent here from the General Web Building forum!) and I have been told that JavaScript is the way to go - can anybody help with the following (I know nothing about Javascript really).

I have an order form and plan to have the data emailed to me (I have FormMail script installed on my server). The form will have the following fields:

Reference Number
Size / Cost
Quantity
Grand Total

Clients will enter the ref no., choose a size/ cost (radio-button), and quantity (text box). I plan to accept details for about different items. I just want the total cost to be displayed in a box at the bottom before the form data is sent to me.

Can anybody point me in the right direction of how I might go about this? Tutorials / sample code etc.

Populating Order Form From Mysql Database

Oct 1, 2010

Am looking to find the easiest way to populate an order form that customers can email through to us.

I have created a database with 2 fields, id and name.

I would like to be able to have a form on my page with 3 fields, id name and qty.

I want to link the id and name fields on my form to my database so that when a customer starts to type a product id or description it will show a list of available matches. underneath which once clicked will populate the mssing field.

So for example is i have 2 products id 998 green apples and 999 red apples.

Typing in 999 in the id field of the form would populate the name field with red apples and typing red apples in the name field would populate the id field with 99.

if someone didn't know which apples they wanted they could type apples in the name field and underneath it would show both red and green which when clicked will populate both fields.

DOM Modification Speed - Adding Elements

Nov 12, 2010

I'm justing wondering about the behavior of JS in regards to adding elements, suppose I have something like this:

I'm just wondering at the point I hit that "// DO SOMETHING WITH ONE OF THESE DIVS", are all the divs I have added in the DOM available to access?

I ask because I have some code at work in which a tester is reporting an error that happens which I can't reproduce, and they and others have had it a few times.

The only way I can explain it in my mind is if the div is not available to me at the time of execution. So I'm just looking to rule it out or confirm my hunch.

Is document.getElementById("myDiv").appendChild(obj); synchronous and the next line of code wont execute until the DOM is ready or is it in fact a asynchronous call and therefore adding alot of elements to the DOM could result in a lag so some divs or not available straight away.

Logic Error On Limiting The Modification To The Maxvalue ?

Feb 26, 2011

How to create a function that would allow me to add to or subtract from a maxvalue, and thankfully I got help regarding that. However, something's got me stumped for the past few weeks that I still can't resolve...

This is the relevant code:

As it stands, it works as long as the total value is less than or equal to the limit (for advantages it's 15, for disadvantages it's 10). However, the moment it goes past the limit -- for instance, if you change Antisocial's value from 2 to 7, or if you add several additional checkboxes with any values -- the whole thing starts going crazy; specifically, maxvalue doesn't revert to 40 when the all the checkboxes are unchecked.

What I'd want to happen is that the user cannot select or apply advantages or disadvantages if the maximum advantage is greater than 15 or the maximum disadvantages is greater than 10.

I'm thinking that a button for adding disadvantage points to/subtracting advantage points from the maxvalue (that becomes disabled if the user goes past his limit on advantages/disadvantages) is useful at this point, but I'm really stumped on the implementation of the idea. An alternate idea of mine is that all other advantage/disadvantage checkboxes would become disabled if their value is greater than the remaining number of points, but I don't know how that is possible either.

JQuery :: Using $(document).ready(function() On Elements That Are Created Via DOM Modification?

Mar 14, 2011

I use the following code to add a "click" behaviour to an element:

$(document).ready(function(){
$("#element_id").click (function(){
...... do something ....

[Code]....

Part of the node I clone is the element from the first piece of code I quoted. The addRowJob function also changed the ID of every element in the node I cloned. This way all IDs remain unique. Lets say the element in question has the ID "#element_id". Now I clone the node (which includes the element) and the cloned element gets its ID changed to "#element_id_new".

Of course I now want this newly append element ("#element_id_new") to have a click event attached to, but even if extend my $(document).ready(function() to:

$(document).ready(function(){
$("#element_id").click (function(){
...... do something ....
});

[Code].....

I simply doesn't work for the appended element.

My guess is that the $(document).ready(function(){ only fires when the document is finished loading. At this stage there is no element with the ID "#element_id_new" and therefore the click event can't be attached to the element. Makes senses...

But how do I get this click event attached to the newly appended element with the ID "#element_id_new"?

Ajax :: Modification - Function To Load Text File Information From The Server

Sep 24, 2011

I have been successfully using the following "myAjax" function to load text file information from the server.

ajax.js:

After I load the text file, I store the text "records" into an array by doing something like this:

Where the '}' character is my record delimiter. It could just as easily be ' ' or ' ' or the like.

Again, I am not having any problems doing it this way as it suits my current needs.

Now the question(s)

1. Does the call to read the text data from the external file always read in the entire contents or can I read one line or delimited record at a time and store it to the array directly without the text storage?

2. If the text is always read completely (my suspicion), can I safely delete the "TextInformation" after I convert to the array format? Is there any memory penalty for doing it this way as the text information can be somewhat lengthly and I don't like the idea of having doubled memory usage when I only need the information in array format anyway?

This is the idea I am considering, but I don't know if there are drawback to this method of if there is a better way to accomplish the task.

Help With Form Auto Update

Jan 4, 2006

For instance, Box A has a blank entry and I enter in 5. Box B I enter in 6
so in Box C it should automatically give me 11 (if the code I put in is to
add box A and B). Then in Box D I put in 3 (say to subtract from A and B
combined) so then Box C adjusts to give me 8.

Don't worry about the math as that's all taken care of it, I just need to be
able to know how to update on the fly like this.
