May 15, 2011

I am trying to define a variable as follows:

var music_id = $(this).attr('id');
var mix_class = $('#le' + music_id);

In other words, if music_id is mix3, I want mix_class to be #lemix3.The above code is not working for me and I would like assistance as to the syntax to produce such a result

JQuery :: Defining Dynamic Selector With Variable?

May 20, 2010

How can I dynamically specify a class value to use in a selector? For instance, I have a number, and I need to identify an element that ends with that number. In this case, there are four divs that have class values of

my_id_0
my_id_1
my_id_2
my_id_3

I have a 0 (obtained previously in the code) stored in the value tabId, so I want to get the values of the class attribute for <div id="my_id_0">. How do I create my selector? I tried

$("div# parent_element_id #my_id_" + tabId).attr("class");

but it comes back as undefined. Do I need to define it as a variable and put it in theelector that way? Or is there another way?

JQuery :: Defining Selector As Global Variable?

Jun 3, 2011

I'm trying to define a selector as a global variable and it keeps coming back undefined. I tried creating a namespace for it but had no luck. I would like to be able to reference the sliderRange, currentMin, currentMax globally.

SLIDER.range = $('#price-slider').slider('option','values');
SLIDER.min = SLIDER.range[0];
SLIDER.max = SLIDER.range[1];

Extract Part Of A URL And Put It Into A Variable?

Oct 18, 2010

I'm sure this is probably a simple question, but I'm going to ask anyway. I need to extract part of a URL and place it into a variable for use elsewhere on the page. The part to be extracted will be of varying lengths.

As an example, if I have the following [URL] I need to extract "SS". Basically, anything that appears between "static.nsf/" and "/Steve's_APT_test_page". That value needs to be put into a variable and called elsewhere on the page. For testing purposes, I'm using the following code, just to see if it works (which, so far, it doesn't):

<script type= type="text/javascript" language="javascript">
var page_url = window.location.href;
var segments = page_url.split("/");
alert(segments[4]);
</script>

JQuery :: Specifying Variable In Parent To Match Variable In Ajax File

Oct 21, 2011

Ok, so I've built a member search using ajax to change the results each time a filter is changed. It works great, except one minor issue that I'm struggling with...I just can't specify dynamically in the parent file that linkclass$id opens linkclasscontent$id as I don't know of any way to pass that $id variable back over to the parent.

Dec 13, 2011

I want to load an html div in a variable, modify it in another variable; and then change the document injecting the contents.

3. I change the html in the doc

I've used the debugger, and all steps give the expected results, except of newcode.html(), which is a null string. Why?

Declare A Variable Inside A Function - Returns White Space - Not Variable Value

Aug 17, 2010

I am trying to declare a variable inside a function and use it later on in my code... but it just already returns white space... i.e. not variable value. I am setting it within this function:

function show_video1(){
document.getElementById('video1').style.display="block";
var video1Name = "Education World News (Part 1)";
document.getElementById('video2').style.display="none";
document.getElementById('video3').style.display="none";
document.getElementById('video4').style.display="none";
[Code]...

and trying to call it later on with this: <script type="text/javascript">document.write(video1Name)</script> It might be worth noting that each one of my 11 videos will hace a different name.

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?

ChangeYear - GetFullYear - SetFullYear Functions - Extract The 4-digit Value From The Today Variable And Store The Value In A Variable Named Year

Oct 13, 2009

a.) specify two parameters for the changeYear function: today and holiday.

function changeYear(today)(holiday){

b.) in the first line of the above function, use the getFullYear() date method to extract the 4-digit value from the today variable and store the value in a variable named year.

first line

c.) in the second line; use the setFullYear() date method to set the full year of the holiday date object to the value of the year variable.

second line

d.) in the third line, use a conditional operator on the year variable. The test condition is whether the value of the holiday date object is less than the today date object. If it is, this means that the event has already passed in the current year and the value of the year variable should be increased by 1.

third line

e.) in the fourth line of the function, again set the full year value of the holiday date object to the value of the year variable.

External File The LoadTabs Variable Will Not Allow To Pass It A Variable

Dec 1, 2009

I start outside of the external JS file by: reviews.init(); reviews.initialiseContent('comment'); This loads my data and loads + sets the comment tab as default. My problem is that in the external JS file (shown below) the loadTabs variable will not allow me to pass it a variable: contentDiv.onclick = this.initialiseContent; Whenever I pass a variable here it errors, am I setting this up correctly, should I be using prototype for my this. variables? Interested to hear back on if this structure of code is the right way to go about this and also how I can pass a variable in this way :)

Get A Variable From A Remote Page And Define As Variable?

Apr 26, 2011

I have a programing problem that have been around for ages. I have search on google using several expressions and words and after hours of digging i'm still unable to do it.I would like to get a value from a HTML page hosted remotely with an inconstant value. Then define this value and name as a javascript variable and apply or show in my page.P.S. Is there any way to make a domain lookup in javascript? I mean a user enters a domain and the script converts to an ip and shows to the user. If not thanks, probably it can only be done in the server side...
