JavaScript - Adding An Additional Element To A Javascript Function

Hi!

I'm trying to toggle a class and one works and the other does not and I don't know why. I'm just getting my feet wet with jquery and javascript and I figured this was a pretty easy task to take on! Maybe.

Link to the page:
Franklin Township Soccer Club - Change Field Status

My sad, sorry attempt =|

Code:

	$( "li.open" ).click(function() {
	$( this ).toggleClass( "closed" );
	});
	
	$( "li.closed" ).click(function() {
	$( this ).toggleClass( "open" );
	});

The first function works with open, so I figured I'd just use opposite on closed! Ha! I don't think so!

In the end within those function there is an element in a form on that page it's hidden. I'd like to change the value from a 0 to 1 for vice versa. That' will be my next step. If you could give me a little nudge in the right direction I'd appreciate it! But first understanding why one works and the other does not, that is the primary mission!

I do appreciate any help given!

Hello Pros.
I am having a problem with getting id of the active element which calls function savePanelPosition(), as a result, I cannot get a new location of this element and pass it to my Page Method SaveCoords() All draggable panels are created dynamically in code-behind. Please, see the javascript code below. Any ideas/help are greatly appreciated

function pageLoad() {
var Max = "<%=qtyMax%>";
for (i = 0; i < Max; i++) {
$find('DragP' + i).add_move(savePanelPosition);
}
}


function savePanelPosition()
{
var elem = document.activeElement;
var loc = $common.getLocation(elem);
PageMethods.SaveCoords(elem, loc.x, loc.y);
/* there is a call to PageMethods.SaveCoords(), but elem = objectHTMLBodyElement, loc.x=0, loc.y =0 */
}

Hello

I am fairly new to Javascript. I have a function which takes a string which consists of key value pairs and sets a form control based on key being the form element name and value being the value to set. eg string could be "key1=orange;key2=2;key3=whetever"

Here is the function:

function processresponse(frm, serverResponse) {
var items = serverResponse.split(";");
for(var i = 0; i < items.length; i++)
{
var item = items[i];
var eqchar = item.search("=");
if(eqchar != -1)
{
var key = item.slice(0, eqchar);
var value = item.slice(eqchar+1);
var elemname = key;

if(document.getElementById(elemname) != null) {
var type = frm.elements[elemname].type;
if (type=="checkbox") {
value == "1" ? frm.elements[elemname].checked=true : frm.elements[elemname].checked=false;
}
else if (type=="text"){
//do processing for text (text input)
frm.elements[elemname].value = value;
}
else if(type=="select-one"){
//only one is openformmode - default to [0] - true
if(value == "0" || value.length == 0)
{
frm.elements[elemname].options[0].selected = true;
}
else
{
frm.elements[elemname].options[1].selected = true;
}
}
else {
alert("unknown ctrl type: " + type + " name: " + frm.elements[elemname].name + " val: " + value + " key: " + key);
}
} //if(frm.getElementById(elemname)
}
}
}

The problem line is:
var type = frm.elements[elemname].type;

elemname is case sensitive so if for example the form element is called dog and the string elemname is Dog, then the line fails with Error: 'elements[...].type' is null or not an object

So my check if(document.getElementById(elemname) != null) is insufficient to guard against this.

I realise I could do a try catch but there must be a more legant way than that.

How can I test the formname more reliably?

Any ideas would be very welcome.

Hey guys,

I'm using a couple of JQuery plugins:

Quicksand - Shuffle/re-order
PrettyPhoto - standard lightbox type image viewer

I'm using Quicksand to filter my images, like a gallery, sorted into categories for my work; illustration, website, applications etc.

This is working fine.

I'm using PrettyPhoto to allow the user to click these images and see them in a larger size. This works fine when 'all' is selected from the quicksand menubar.

However, if I filter the list to any other option, PrettyPhoto doesn't work and clicking the image results in it opening in a new page.

Essentially, I need to re-call or re-load PrettyPhoto after the animation for filtering ends. But I don't know how.

You can see my galllery at:

http://www.gurugroup.net/#3

You can view the PrettyPhoto and Quicksand Javascript files he

http://www.sim-modding.com/stuff/javascripts/

I assume the re-call line would go somewhere around he

Code:

// Gets called when any animation is finished

Thankyou in advance.

Hi all,

I have what I hope will be a simple question for someone to help me with.

I simply want to add a timeout to the folowing code:

Code:

$(function(){
			
			
			$('#slides').slides({
		
				effect: 'fade',
				crossfade: true,
				preload: true,
				preloadImage: '<?php bloginfo('template_directory'); ?>/img/loading.gif',
				
				 
				play: 4500,
				
				pause: 500,
				hoverPause: false,
				animationStart: function(current){
					$('.caption').animate({
						bottom:-35,
						
					},100);
					if (window.console && console.log) {
						// example return of current slide number
						console.log('animationStart on slide: ', current);
					};
				},
				animationComplete: function(current){
					$('.caption').animate({
						bottom:0
					},200);
					if (window.console && console.log) {
						// example return of current slide number
						console.log('animationComplete on slide: ', current);
					};
				},
				slidesLoaded: function() {
					
					$('.caption').animate({
						bottom:0
					},200);
				}
			});
		});

As you can see this is a slideshow code. All I want to do is delay the first slide sliding in when the slideshow loads. I have tried wrapping the whole function in a settimeout but to no avail.

Thanks in advance

Hi there, I'm looking for some help with modifying an existing function which controls the highlighted states of a multi level js accordion menu. I have had to use javascript due to certain css elements not working in safari browsers.

My problem is due to the multi level aspect as when a sub link is clicked, the parent link above it then deselects. I need the parent link to stay active when its sub links are clicked and only deselects when a link outside of that list is clicked upon.

I understand the theory of adding a conditional statement but simply don't know how to apply it correctly within the function...any help would be very much appreciated.

Here is the existing function which tells a link to be active or selected:

Code:

var Lst;

function CngClass(obj){
 if (Lst) Lst.className='.topnav';
 obj.className='selected';
 Lst=obj;
}

and here is the menu code:

Code:

<ul class="topnav">
	<li><a href="#">Home</a></li>
	
	<li><a onclick="CngClass(this);" href="#">Top Link 2</a>
		<ul>
			 <li><a onclick="CngClass(this);" href="#">Cookies</a></li>
			 <li><a onclick="CngClass(this);" href="#">Events</a></li>
			 <li><a onclick="CngClass(this);" href="#">Forms</a></li>
			 <li><a onclick="CngClass(this);" href="#">Games</a></li>
			 <li><a onclick="CngClass(this);" href="#">Images</a></li>
			 <li><a onclick="CngClass(this);" href="#">Navigations</a>
				<ul>
					<li><a onclick="CngClass(this);" href="#">CSS</a></li>
					<li><a onclick="CngClass(this);" href="#">JavaScript</a></li>
					<li><a onclick="CngClass(this);" href="#">JQuery</a></li>
				</ul>
			</li>
			 <li><a onclick="CngClass(this);" href="#">Tabs</a></li>
		</ul>
	</li>
	<li><a onclick="CngClass(this);" href="#">Tutorials</a>
		<ul>
			 <li><a onclick="CngClass(this);" href="#">HTML</a></li>
			 <li><a onclick="CngClass(this);" href="#">CSS</a></li>

					<li><a onclick="CngClass(this);" href="#">JPA</a></li>
					<li><a onclick="CngClass(this);" href="#">Contact</a></li>
				</ul>
			</li>
			 <li><a onclick="CngClass(this);" href="#">Tabs</a></li>
		</ul>
	</li>
	<li><a onclick="CngClass(this);" href="#">Contact</a></li>
	<li><a onclick="CngClass(this);" href="#">Upload script</a></li>
</ul>

Thanks for any help or advice.

Heya guys

I'm looking for someone with a vast knowledge of Javascript... by any chance someone over here has some time to help a newby out?
(I think 10 minutes should be enough)



<INPUT TYPE="button" NAME="addToArray " VALUE=" ATA " OnClick="addToArray() "> <!--Add To Array -->
<INPUT TYPE="button" NAME="clearArray" VALUE=" CA " OnClick="clearArray()"> <!--Clear Array -->
<INPUT TYPE="button" NAME="showArray" VALUE=" SA " OnClick="showArray() "> <!--Show Array -->

These are my buttons.

What I want them to do is simply add something to an array, clear the array and show them on my screen.

I am working on an HTML project that displays a field with a number in the field by each day. What it does is start at 0 on day one. Each day it adds a 1 to the field. Day 2, the field would say 1, then day 3 would say 2, and so on. I am not sure how to approach this. This is also displayed in an HTML format. I want to to be automatic and change as the date changes. I will also need a way to reset it back to zero if possible.

I am using a jQuery slider for a website but the W3C comes up with invalid because:

document type does not allow element "div" here
.before('<div id="buttons">')

Code:

<script type="text/javascript">
$(document).ready(function() {
$('#slider')
.before('<div id="buttons"></div>')
.cycle({
fx: 'fade', // choose your transition type, ex: fade, scrollUp, shuffle, etc...
pager:  '#buttons'
});
});
</script>

Any help with this would be appreciated thanks.

HI
I want to write a search for my site .I make a new panel in the left of my menue and it has a text input and an image which when that user click on it javascript opens a new window which is a php page.The part I don't know how to do is when the user click on the image it should get the content of the text input and pass it to the url.For the hyperlink of the image I use "<a href="javascriptpen_window('includes/func/search.php?id=" But I don't know what should I write after that to get the content of the text input and put it in the next of the id.
How can I do so?

Thanks

Hi, firstly I apologise if the title of this thread isn't quite accurate. I'm sure you've all heard it before but I am a complete newbie to Javascript so again: apologies if this is boring and tiresome to even read, let alone help with!

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 he http://samdelara.co.uk/previews/banq...ation-form.htm and the code I am trying edit is below:

function checkAvailibility()
{
// re-calculate...
calculate ();
if ( isName() && isAddress1() && isTown() && isCounty() && isPostcode() && isYourEmail() && isFuncDate() && somethingToQuoteFor() && isYourEmailValid() ) {
document.ordersummary.emailQuote.value = "No";
setValue();
return true;
}
else
{
return false;
}
}


function isName() { if (document.ordersummary.Name.value=="") { alert ("\n Please Enter Your Name")
document.ordersummary.Name.focus(); return false; } return true; }
function isAddress1() { if (document.ordersummary.Address1.value=="") { alert ("\n Please Enter Your Address")
document.ordersummary.Address1.focus(); return false; } return true; }
function isTown() { if (document.ordersummary.Town.value=="") { alert ("\n Please Enter Your Town")
document.ordersummary.Town.focus(); return false; } return true; }
function isCounty() { if (document.ordersummary.County.value=="") { alert ("\n Please Enter Your County")
document.ordersummary.County.focus(); return false; } return true; }
function isPostcode() { if (document.ordersummary.Postcode.value=="") { alert ("\n Please Enter Your Postcode")
document.ordersummary.Postcode.focus(); return false; } return true; }
function isYourEmail() { if (document.ordersummary.YourEmail.value=="") { alert ("\n Please Enter Your Email")
document.ordersummary.YourEmail.focus(); return false; } return true; }
function isFuncDate() { if (document.ordersummary.FuncDate.value=="") { alert ("\n Please Enter Your Function Date")
document.ordersummary.FuncDate.focus(); return false; } return true; }
function isemailonly() { if (document.ordersummary.emailonly.value=="") { alert ("\n Please Enter Your Email Address")
document.ordersummary.emailonly.focus(); return false; } return true; }

Any help with this would be very much appreciated and once again, I apologise for my distinct lack of knowledge in this area!

Sam

I am learning to programme in HTML5 and Java, and I'd like some assistance with what I am sure is a pretty basic matter, if possible please? If anyone can assist it would be most appreciated?

I am using Dreamweaver (latest version)...

This code here below when run produces a google map with a street address look up input.

I am wanting to learn how to look up an address and submit this to resolve within the map, and also to insert a place holder... I'd like the look up box to sit within (and overlay) the map top left area - at the moment it sits below the map - which i guess is because I haven't inserted a frame??

Many Thanks grin):

Hi,

I am facing a problem in passing replace() function as an argument in user defined java function, can any one help me how to resolve it?

intention is to pass a file path to my user defined function, but before passing the path i want to replace the character '\' to '\\'

I am posting my javascript function he

<a href="#" onclick="OpenDocPreview('<%# Eval("PATH")%>'.replace(/\\/g,"\\\\"), '<%# Eval("Filename")%>')"><%# Eval("DocTitle") %></a>


function OpenDocPreview(url, docname) {
alert('message from search base : ' + url + ' ' + docname);
}

thank you,

i want to add a tooltip----click to copy to the Copy To Clipboard... box like this site(http://www.retailmenot.com). the yellow part with a Scissor. but when i used jquery to add it. it doesn't work. why?

i test it on this
site: Quote:
http://bowser.effectgames.com/~jhuck...rd/test10.html

Code:

$(document).ready(function(){
   $("#d_clip_container").hover(
  function () {
    $(this).append($('<span class="tip">click to copy</span>'));
  },
  function () {
    $(this).find("span:last").remove();
  });
})

i have added the jquery library. The reason of the tooltip can't work maybe the copied text is wrapped by the flash, but this site (retailmenot.com) can do. i don't know why? how to do it? thank you.
