Retrieving A Variable And Then Incrementing And Displaying Onclick?

Feb 10, 2010

Simply put, I need to take a variable (The number '20' in this case) that is displayed by an input box on my web page and plug it into a function so that whenever I click on a button, the number in the input box will decrease by 1.

Seems simple enough, though for hours I've been going at it with no luck. Skipping the rest of my code - I currently have:

<head>
<title> Online Slots </title>
<script type="text/javascript"
src="http://dave-reed.com/book/random.js">

[Code].....

The entire code is a slot machine project that's supposed to be extremely simple where you hit the button and it spins 3 wheels, 3 of the same image and you win. Every spin takes $1, every win gives $13.

The majority of the code is already working, however for some reason I appear to be failing badly at getting the read out to show a decrement of $1 every time you push the button.

I've tried so many different ideas that I've found across w3schools, webdevelopersnotes, dave-reed, ect - and so far I haven't been able to get any of them to work correctly.

Adding An Incrementing Variable To A Script To Create Different Class Names

Feb 12, 2009

Last evening I ran across this script which I think will address a need I have; replacing my radio buttons with images. The one difference I have is that I need to use a different button image for each of the 5 buttons in my group.Unfortunately, the script dose not apply unique classnames within the generated mark-up so if I'm to use this I need to apply some sort of counting variable that increments and use this variable to append the classname with.Around line 52/53 of jquery.checkbox.js is

Code JavaScript:

/* Wrapping all passed elements */
return this.each(function()
{

JQuery :: Retrieving Nested XML Nodes And Binding To OnClick Events

Jan 26, 2010

I have created two onClick events that i need to combine into one with jQuery. I have an unordered list:

Code:

<ul id="coverTabs">
<li class="currentTab"><a href="#">Individual</a></li>
<li><a href="#">Couple</a></li>

[code].....

So the active tab is set in the HTML to Individual by default.The following jQuery sets the active depending on which one is clicked.

Code:

$('ul#coverTabs > li').live('click', function() {
// Clickable tabs
// Removes default class applied in HTML and onClick adds 'currentTab' class

[code]....

what i want to achieve is when a user clicks a tab we call the XML document. The appropriate tab name is fetched and subsequently when a user clicks on a column under that tab the appropriate level cost data is displayed on the page.

Onclick Defined Variable - Print Variable Some Place In Document

May 28, 2007

i'm not really sure how to explain this, since I know nothing about javascript, so i'll try and illustrate by the use of php (hope it makes sence)

I have a set of different links, like:

<a href="link.com?page=text1">text 1</a>
<a href="link.com?page=text2">text 2</a>
<a href="link.com?page=text3">text 3</a>
etc, where page is dynamic and can be anything I chose..

Another place in the same document, I echo out what the page variable is, like:

echo "$page";
so when clicking "text 1" the echo will output what i've defined the page to be, in this case "text1" ..

So I want to be able to click the links and change the output of the echo all depending on what i've defined in the link - without refreshing the page!

Is there any easy way to do this?

Displaying Javascript Variable In Text Box.

I can do this by showing a msgbox every time try increments but this
is annoying to use. I have been trying for hours to get this to work,

Displaying Dynamic Variable Content (String T2)

Feb 15, 2009

I'm new to javascript and still trying to learn my way around. Below is my code

<script type ="text/javascript">
var a1 = "2";
var t2 = "hello world";
var total = ("t" + a1);
alert(total);
</script>

That code will display the string "t2" rather than the value of the variable t2. How do I make javascript display the value of the variable rather than the string?

I have a javascript rich text editor code...

Incrementing A Field

Jan 17, 2006

I've got an embedded system that uses a javascript-enabled browser as a
front end.

The input system consists of an encoder which generates + and - chars, and
a couple of keys that generate Tab and Shift-Tab for navigation.

Each field in the form is numerical, and has certain properties; for
example, one field represents %, and has a min of 0, a max of 100, and
increments of 1.

I need to come up with some javascript code that would take take those +
and - chars, and increment/decrement the field values so that the user can
'dial in' the value they need....

Incrementing Button Value On Click?

Oct 12, 2011

I need to make an HTML button whose value is "Times clicked: 0" and every time the user clicks it the value increments the number so it will say "Times clicked: 1" after clicked and so on. I don't know if a javascript function is the best way to do this, I know how to change the value on click but I don't know how to make it increment only the number

<INPUT NAME="myButton" TYPE="button" VALUE= " (I don't know what to put here) " onclick=increment()>
<script type="text/javascript">
function increment() {
document.myForm.myButton.value= (how do I make it increment?)
</script>

Determining Whether Mouse Is Decrementing Or Incrementing?

Apr 20, 2010

I'm having an issue determining whether the mouse is increment or decrementing.

Code JavaScript:
_self.mousedown(function(e) {
var initialValue = parseInt($('#value').val());
var initialMouse = e.pageX;

[Code]....

As I move my mouse to the right, this returns true. When I move the mouse to the left, this still returns true; because the currentMouse value is still greater than the initialMouse value.

Passing Variable In Onclick?

Apr 2, 2009

Basically, I have a form with some text fields, and I want to put a button next to each text field, so that when a user clicks on the button, it increments the value in the field by 1. I know how to do it if I know the id of the text field, but what if the id of the text field is a variable? How do I do it? Here's my code:

<script language=javascript>
function process(v){
document.getElementById('order_item' + v + '_quantity').value++;

[code]....

My issue is with my onclick statement:

<input type="button" value="Add +" onclick="javascript:process(0)">

This works fine for my first field, but I need to have one for every text field, so how do I pass my counter variable (which determines the id of the appropriate text field) to the process function?

Changing Variable Value With OnClick?

Nov 13, 2011

I am building a site where I want all links to partial page reload using xmlhttprequest and innerhtml. I have done this before, butI always had to have a seperate xmlhttprequest function for each link. So this time I am trying to write just one function, and have the onClick change which document the request is getting. It is not working and I appear to novice to figure out why. Here is the code, i have bolded some relevant lines:

<script type="text/javascript">
function ChangeContent()
{
var whichPHP;

[Code]....

Also, if I use the innerhtml function to write another of these hrefs, will that link be able to access the function if it is in the header, or should I put the entire function in a .js file on the server? The point of all this would be that the entire page never reloads and all the text content is swapped out on demand.

Calculator Calculation - 1st Number Entered Displaying It And Storing It In The Variable "memory"

Feb 13, 2011

This is calculator program that I have gotten stuck on. Here is where I think I am at:

The program is now taking the 1st number entered displaying it and storing it in the variable "memory".

Operation (+,-,*,/) is added to the memory in function action1() but then when the second number is entered it replaces memory with the second number. How can I get the variable memory to the whole string of 1st number,action, 2nd number?

Also once I do get that working correctly:

Wouldn't eval(document.calculator.display.value= memory) in my HTML for the "=" give me the calculation. (if I could figure out how to have memory store the 1st number and action1 and 2nd number all together) Or would eval(document.calculator.display.value) do it for me.

Each Time The Visitor Access The Page Read The Cookie And Display The Corresponding Image / Incrementing / Updating

Jul 12, 2011

My requirement: Each time a visitor arrives at a specific webpage i want the main image on the page to be different, or more specifically, one of 6 images which will be shown in rotation. Solution: Set a cookie. Each time the visitor access the page read the cookie and display the corresponding image. Then increment the value and rewrite the cookie, so that next time they'll see the next image in sequence. NB: if the cookie does not exist (first timer) or is at 6, then the value is set to zero (and then incremented).

Problem: Can't get my coding to work. Specifically it just doesn't do anything - no error message, no cookie written. I'm a very novice scripter, as in I've cobbled the coding together from bits off the net that i think i've managed to grasp some kind of an understanding of. Very suck it and see - so far lots of sucking and no seeing!
