My site is run on wordpress, but I'd like to customise the menu so that if the user is logged in the menu displays "Logged In" and if they are not it displays "Log In".Normally I would just use an if statement in PHP to output the required html, but as I can't use PHP code in the menu item I need to use Javascript. :mad:So, the way I figured this would work is:1) PHP code in the header checks to see whether the user is logged in2) This code then outputs JS to define a variable (varCheckLogin)3) JS within the menu checks varCheckLogin and outputs the html i wantThis sounds good hopefully. :DUnfortunately this isn't working at the moment. The code I have is:HEADER: (I know this works as the variable is being output correctly in the source code)
I would like to learn jquery but have already stumbled upon a little problem.
My whole website is programmed in PHP. On every page I include my header.php containing the header, login bar etc. I am now trying to show/hide a set of divs in my HTML BODY.
Now I understand that I need to put my jquery code in my HTML HEAD tags, however, I don't want to put it in my header.php because then the jquery will be included in all my pages.
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!
I am currently working with a cms system that doesnt keep within the correct name conventions (pre defined).Within a form, I simply want to set a date to todays date:
<script type="text/javascript"> function initdt(mf) { var t = new Date;
[code]...
This works perfect on a form I create, but sadly I must use a form within a pre defined system that uses "01-date" Is there a way around this? A simple way of setting 01-date to t.getDate();
I've been writing a new layout for part of my web page.
The java script is not creating the list. When I check Firebug I get an error:
QuoteMovies[movctr] is undefined [Break On This Error] MovieList+= Movies[movctr][2]
If I take out the var MovieList and just have it print the text "MovieList" instead of the contents of MovieList the code tries to run. I'm not sure why it won't copy the content of the var MovieList.
Live test version of my movie page
Here is my code:
It's also weird that is says that Movie[] is undefined instead of Movie[][].
where the eval function returns the path of the pictures.This works fine! but in IE I get an error saying a100image12 not defined (and image13, image14, etc), because that image is not in the javascript file.So, how can I test in advance if a variable exists in the file?? Note that I take the name of the next picture based on the current one.I mean,I take the current picture from the div, lets say a100image10, I add one, and I try to look in the file for the variable a100image11.
I'm having some issues with firefox, chrome seems to work ok. Firebug is giving me an error stating country is not defined. The line it's saying it's on is where the function for an ajax call to populate a select input on page load.[code]...
Using a while loop in a function, I am trying to test an input character against a stored string of characters. I want the function to return the input character only if it is not in the stored string of characters. The code I've prepared is as follows:
<SCRIPT language = "JavaScript"> var storedLetters = 'sideways'; function requestLetters(aString) { var validLetter ='';
[Code]...
The code works fine if I remove it from the function wrapper but if the function is called I keep getting an error message that the variable validLetter is not defined. :confused: Can anyone see why this is the case?
I'm trying to select a class (.home) and an ID (#something) at the same time,
normally I'd use:
$(".home,#something")
but in this instance, the ID is already stored in a variable called "newpage" - I'm trying the following:
$(newpage,".home")
(note, selecting the id on it's own with just$(newpage) does work, so I know the issue isn't with my variable, it's just a matter getting both the class and the variable stored ID selected at the same time)
In the function 'formToArray' the variable 'max' is causing a conflict in my application. The reason being that max is not explicitly defined as a var so it becomes a global variable.So IMHO:
#520 - var i,j,n,v,el; for(i=0, max=els.length; i < max; i++) {
should be changed to
#520 - var i,j,n,v,el, max; for(i=0, max=els.length; i < max; i++) {
How to: pass local variable from <head> JS function to <body> textarea

I am working on a website that uses a random header. I have been trying to figure out how to adjust the code so that the header also serves as a clickable link.
Here is the code that I have:
What do I need to add in order for the header to also serve as a link? I am completely new to JavaScript and I don't understand it very well.
How do I acess the whitelist variable from outside the sendrequest() function?
Iv tried saving it to a window.var variable with no luck. Iv tried creating a div and assigning it's innerHTML as the whitelist variable and getting it later with no luck. The fact that it's a chrome extension complicates things because i dont actually know if i can create elements from where the script is located.
I'm trying to make my body content scroll at the same time as an iframe located within the body. This has to do with the age old problem of mouse focus on iframes. When my mouse reaches the iframe and it takes over focus, I would like the body to keep scrolling until the iframe is right at the top of the screen. After that I want to relinquish focus to the iframe. I don't mind if the iframe starts scrolling as soon as the mouse reaches it, so long as the main body keeps scrolling for a while.
I've got some text that I want to change what it says:(63%) on RRP (£80.00) The percentage value and RRP Price will change dependant on the product and its discount. All I want to change with jquery is the text:
I know it's something stupid I'm doing but I can't figure it out. Essentially I'm trying to load two objects with URLs with two websites that can be loaded(displayed) and unloaded(hidden) at the click of a button.
I've spent an hour trying to debug this and I'm at my whits end! I'm doing this with changing the width and height of the divs that contain the objects that will load the websites. But, in Firefox I get an error in the error console saying : loadUnload is not defined. why? code...
It's possible to style document.body not to start at 0,0 for example: body {width: 1000px; margin-left: auto; margin-right: auto;} This means that X/Y of the body is not 0,0 but how can I find out what the position is using javascript? document.body.offsetLeft; is 0 and offsetParent is null yet if I position something absolutely at 0,0 it goes to 0,0 of the window, not the body!
when I load a new page with location.href, ie doesn't set the http referer header while firefox&mozilla does...
I tried the click() method on a hidden link, this times it works on ie, but firefox says that click is not a function
[... <a id="ref" href.......>...</a> .... document.getElementById("ref").click(); ....] Is there any method which I can set this header manualy or make ie set it properly? Or any other idea?
I have a situation where I'm currently using Basic authentication (the server issues a 401, the client pops up its window, etc., etc.).
Instead of having the server send out a 401, I would like to send out my own page that would create the proper header field for all subsequent requests from that client. Can such be done with JS? Can someone point me to an example?
I do not need encoding. This is on an intranet and the authentication is being used mainly to return different information to different users as opposed to trying to keep out the "bad guys".
Is there a way to set the value of HTTP header Referrer to null or to any specified value?? I have tried doing this
document.Referrer= null
but document.Referrer is a read only property therefore the value can't be changed and a Javascript error is occuring. Any ideas on how this can be achieved.
