Mar 30, 2010

Im trying to do the following thing, I have a function in javascript which I want to use to call anAJAX event, during this event the variable that is set in the function needs to be passed to the file called by the AJAX event. Basically I create 2 different versions of the same stuff inside the AJAX called files using the variables. But im running into some cross browser related issues, this all works fine in FireFox. However in Internet Explorer it sometimes works but gives javascript errors on line 99999ish. I have the following setup:

JQuery :: Get $(this) To Work In A Function That Has To Have Variables Passed To

Apr 28, 2011

I want to call a javascript function when a <span> is clicked, pass two variables to it, and then use jquery to hide that span.

A simple example is:

The variables (1,3) & (8,9) are loaded dynamically with a php script. Adding the two variables together isn't the intent of the script, but it seems the simplest way to explain what i'm after.

So how do you get $(this) to work in a function that has to have variables passed to it?

JQuery :: Bind Variables To A Function Call (like In Prototype.js Function#bind)

Nov 4, 2010

is there a way in jQuery to bind variables to function calls similar as prototype.js does it? See [URL]

E.g. in the slideUp method of jQuery you can specify a callback that is called after the effect has finished. I would like to bind a variable to this call so that it is used inside of this callback as a closure.

Local (var) Variables At The Top Of Function?

Jun 15, 2007

In jslint's doc it says, "JSLint does not expect that a var will be defined in a block. This is because JavaScript blocks do not have block scope. This can have unexpected consequences. Define all variables at the top of the function." What are some of those unexpected consequences?

Cant Use Passed Variables In Function

Oct 11, 2010

I'm trying to reuse a script I have but, I'm not able to due to the fact I can't use some variables in a function.

I would like to know why I am not able to use passed variables in javascript.

For example: I call a function submit_data( 'newDomainForm', 'add_domain', 'list_div' ), in the function itself I would like to use the form name (first variable passed) as document.form.domain_name.value.

Later on I would like to use the div id: list_div in document.getElementById( div_id ).innerHTML. This doesn't work.

I have to put the name of the actual div like this: document.getElementById( 'result' ).innerHTML

And to get the value of a form element I have to put the actual name like this:

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.

Looping Variables In A Function Literal

Oct 19, 2005

Below is a stripped down example of code I'm using to count links in a
list. My intent with the ShowLinkNumber() function was to display the
number of the current link. (e.g. click on link 2, and the message "2"
pops up; click on link 4, and you see a "4.")

For reasons I can't trace, my function always displays the last number
in the list. Why does it do this, and can anyone suggest a way to
achieve my goal without adding markup? Code:

Passing Variables To A Pop-up Page Function?

May 24, 2010

I want a page with a hyperlink that passes a variable to another 'pop-up' page (in this case a name, its just an example) and new pop-up page prints a message followed by the variable thats passed.

Here is the code as it is right now

<html>
<head>
<script language="javascript" type="text/javascript">
function popitup(a)

[Code]....

In short, I just want the pop-up page to print 'Hello there Toby' or whatever name I choose to pass across. The 'testpopup.html' url is just the initial webpage.

Adding Variables To A Function In A Form?

Jun 17, 2011

I have been asked to make some changes to a form that uses Javascript for the form validation. There is a 'function' that contains the variables of the various form fields and then further code to raise 'alerts' if one of the fields on the form hasn't been filled in. My problem is that for some reason I am unable to add an extra variable to this code after the field of 'County' (this will hopefully make sense when you see the code / link...) and I am stumped as to why. I am able to add variables for all of the other required fields except for 'Postcode' after 'County'. This is the case for both forms. The link is here: [URL] and the code I am trying edit is below. The issues seems to be when I add && isPostcode() to this chunk of code:-

Code JavaScript:
function checkAvailibility()
{
// re-calculate...
calculate ();

[Code]....

Passing PHP Variables To A Function Multiple Times?

Sep 3, 2011

First off I didn't know whether to post this here or in the PHP section since it deals with both, but mostly JS. I have a PHP scraper that scrapes the job title, company name and location from a website and stores them in separate arrays. These values are then extracted out one at a time from the array and stored into a string, that is then passed to a Google Maps API.

I can make this successfully happen once, the thing is I need to do it multiple times. I have an idea on what I should do but don't really know how to implement it (correctly). The idea I had was to create a function in the JavaScript section that accepts three values from PHP. This function would be called in my PHP for loop that extracts the values from the array into a string. The thing that confuses me is that the Map function is called via <body onLoad="initialize()">. Here's the link to my code (http://pastebin.com/rTfzJM16)

Function To Open A New Window With Variables Attached To Url?

Sep 23, 2003

I'm figuring this will need to be done in a function. I'm building a page builder with 2 fields, a textbox called 'title' and a textarea called 'text' (imaginative huh!).

I want to have a preview facility. I've built the preview page, all I want to do is have a javascript button that passes the value of those two text fields to this preview page in the querystring. Is there a way using variables to pass this through?
