Getting Values From PHP Variables To Use In Function?

May 2, 2010

urrently I have the user log in, choose their character, and then go to a page where they can fight random monsters. When they get to the page to fight with the random monsters, the character's information as well as the random monster's information is pulled from tables in my database.

What I would like to do is when the user clicks the Attack button, perform a function that takes the monster's hp ($hp) and subtracts from it the character's attack combat value ($acv1).

how I can access the php variables within my JavaScript code and how I can go about doing this type of calculation?

I'd like to store the monster's hp in a javascript variable, so that when the character attacks, the hp can be updated until the character has reduced the monster's hp to zero, in which case a php script should be run that updates the character's table.

Populate The Form Values OnX And OsX Variables?

Nov 10, 2009

[URL]

This form collects info of the customer who wishes to select add-ons that would be applied to their digital photos. Examples of add-ons:

Photo makeover
Add object or person
Crop image

Have a look at the form [URL]

Once a customer selects one of the options (Photo Manipulation or Photo Restoration for example - radio buttons) and then one or more Add-ons (check boxes in the Html form), enter their details and upload a photo, they hit the submit button and it then takes them to the PayPal checkout page where the total amount is shown. (see image below)

[URL]

The Issue:

In the PayPal page, it now shows the total amount whichever add-ons you select, however it keeps showing "Add object or person" as well as all the 5 main options (radio buttons on the form) no matter what I select. This will be an issue as I will not know exactly which add-ons the customer has selected.

complete the coding so that the add-ons show on the PayPal checkout page.

In order to send the options/add-ons the customer selects I may need to use the onX and osX variables (Where X is a number starting with 0 and incrementing by 1 see below), These can be used to set options for the add-onsthey select. The onO is the "option name" and os0 is the "option choice". So for example:

<input type="hidden" name="on0" value="Photo manipulation">
<input type="hidden" name="os0" value="Whatever add-ons the customer selects">
<input type="hidden" name="on1" value="Photo restoration">
<input type="hidden" name="os1" value="Whatever add-ons the customer selects">

Javascript Variables Not Applying Values

Mar 20, 2007

i have the following snippet of javascript:

liChilds[x].onclick = function(){
toggleSubMenu(sub_menu_id, false);
return false;
}

That code happens within a loop, and sub_menu_id has a different value through each iteration of the loop. For example, if it loops 4 times, then there will be 4 onclick functions and sub_menu_id would change for each one. This should happen in theory, but instead, whichever item you click on, sub_menu_id takes the value of its last value in the loop. (4 in this example)

My question is, how do I make the function toggleSubMenu take the value of sub_menu_id at the time the on click function is created (i.e while looping) rather than taking the value of sub_menu_id when it is actually clicked.

Assign Different Static Values To Different Variables?

Jul 10, 2010

I'm trying to learn JavaScript on my own and am using a Dashcode example (if anybody uses Dashcode, the example is the "Browser" web application template that is shown when Dashcode opens).

Briefly, the JavaScript generates a list of "Locations" in the USA:

Code JavaScript:
// Sample data. Some applications may have static data like this, but most will want to use information fetched remotely via XMLHttpRequest.
var parks = [

[Code]....

I want to retain the layout and structure but, depending on the "Location" have different text for each of the new pages (not "the scenery is amazing etc).

Refreshing A Div - Refreshing A Div Were For Updating Dropdown Boxes ?

Jun 6, 2009

I have been searching high and low on how to do this and I think I'm at a loss because I'm so unfamiliar with js and ajax.What I would like to do is have just a single div on a page refresh every 5-10 secs; the content of the div shows what users are logged on; the content is generated by a query on my db

<div id="players"><?php
$online_query = "SELECT user_log.user_id,user_log.ip,user_log.logged_in,user_log.logged_out,users.username,users.type_id FROM user_log LEFT JOIN users ON user_log.user_id=users.id WHERE user_log.logged_in IS NOT NULL AND user_log.logged_out IS NULL ORDER BY users.username";[code]....

almost all of the google results I got for refreshing a div were for updating dropdown boxes or dealt with some kind of page event...so now I'm at a loss on what else to look for..

Assigning Default Values To Undefined Variables

Sep 1, 2007

I'm moving from php to JavaScript. What I want to do is assign a value to a variable only if the variable hasn't been assigned yet.

In php it would be:

if($variable=='')
$variable='default value'

I thought the equivalent in javascript would be:

if(variable=='')
variable='default value'

Can anyone explain why this doesn't work, or what I should do instead?

Maintain Active Tab And Tab Contents?

Mar 4, 2011

[URL]...When you click the "More" tab, the browser forgets the active tab styling and current tab contents; I don't want these to change - all I want to change on the click "More" tab action is the navigation tab. But my browser should maintain the styling for the last active tab and continue to display its corresponding tab contents. Yet it forgets these details when the user clicks "More".

In particular, when user navigates back and forth between the two tab sets, whatever was the last styled active tab remains styled as such. Browser should remember this.

$(document).ready(function() {

//When page loads...
$(".tab_content").hide(); //Hide all content
$("ul.tabs li:first").addClass("active").show(); //Activate first tab
$(".tab_content:first").show(); //Show first tab content
//On Click Event
$("ul.tabs li").click(function() {

[Code]...

Pass Control (text Field) Values From One Html To Other Using Hidden Variables.

Mar 7, 2007

function submitPartsForm(str) {

var count=document.getElementsByName("partId");
for(var i=0;i<count.length;i++)
{

document.mylist.myNum[i].value= document.getElementsByName("partNum")
(i).value;}

document.forms["mylist"].submit();
}

myNum[] is a hidden variable and partNum is the name of a text field
that has many instances i mean there are many textfields with the same
name so it forms a column in a data table.
