JavaScript - Reusing Jquery Function

Hi, I've been playing around trying to recreate the way in which jQuery chains it's functions for it's "select" then "do" behaviour.

Note: I don't want to chain functions with jQuery, I want to chain them like jQuery.

So based on the jQuery code what I have so far is (doesn't work in IE):

Code:

var x = function(string) {
    return new x.fn.init(string);
};

x.fn = x.prototype = {

    message: '',

    init: function(string) {
        x.fn.message = string;
    },

    log: function() {
       console.log(x.fn.message);    
    }
};

x.fn.init.prototype = x.fn;

var start = function() {    
    x('hello world').log();
};

document.addEventListener('DOMContentLoaded', start, false);

The code works but when I watch '$' in jQuery "fn" & "prototype" show up as being "jQuery()" but in my code when I watch "x": "fn" and "prototype" are both shown as objects containing "message", "init" and "log" and in both cases "init" contains "prototype" which contains my three functions again and the nesting continues seemingly infinitely...

I'm clearly missing something here. What are they doing in differently in jQuery to prevent this endless nesting loop?

I have a slideshow that allows the user to see the previous slide title and the next slide title along with the current slide and its content. I tested locally not in WP and the code worked fine. Once I placed my source within WP everything went south. I inspector the first line in the script seems to be what is having the issues - $(window).load(function(){ and I am unsure what to do next.

The source was used from Edit fiddle - JSFiddle

the page I am trying to get to work is located here - Sevices | Q&D CONSTRUCTION, INC.Q&D CONSTRUCTION, INC.

I am open to any suggestions.

Code:

 <script type='text/javascript' src="//cdnjs.cloudflare.com/ajax/libs/jquery.cycle2/20130801/jquery.cycle2.min.js"></script>
    
  
  <style type='text/css'>
    .cycle-slide {
    width: 100%;
    text-align: center;
}
img {
    max-width: 300px;
}

#next {
    float: right;
}
#prev {
    float: left;
}
.center {
    text-align: center;
}
  </style>
  


<script type="text/javascript">//<![CDATA[ 
 $(window).load(function(){ 
var slideshow = $('.cycle-slideshow');
    maxSlides = slideshow.data('cycle.opts').slideCount;

slideshow.on({
    'cycle-update-view': function(event, optionHash, outgoingSlideEl, incomingSlideEl, forwardFlag) {
        UpdateTitles();
    }
});

function UpdateTitles(){
    var currentSlide = slideshow.data('cycle.opts').currSlide;
    activeSlide = $(".cycle-slide-active");
    activeTitle = activeSlide.data('title');
    
    if(currentSlide == 0){
        nextTitle = activeSlide.next().data('title');
        prevTitle = $(".cycle-slide").eq(maxSlides).data('title');
    }
    else if(currentSlide == maxSlides-1){
        prevTitle = activeSlide.prev().data('title');
        nextTitle = $(".cycle-slide").eq(0).data('title');
    }
    else {
        nextTitle = activeSlide.next().data('title');
        prevTitle = activeSlide.prev().data('title');
    }
    
    $('h1').html(activeTitle);
    $('#prev').html("Previous: "+prevTitle);
    $('#next').html("Next: "+nextTitle);

So, i have this code which retrieves php files for me using jquery and id love to get it working with Jquery history plugin. I tried modifying the code i got from the ajax demo to work for me, but i just couldnt do it as i do not know any javascript really.. ( actually what i tried was simply to change "#ajax-links a" to "#menu li a" and .html to .php ..but nothing.. :rolleyes:


Id be very gratefull if someone would help me out with this one.

All related code can be found bellow (the ones that should be needed anyways):

This is the code that retrieves php files inside "#content" when item from "#menu li a" with the specified id is clicked
Code:

$(document).ready(function(){
	//References
	var change = $("#menu li a");
	var loading = $("#loading");
	var content = $("#content");
	
	//Manage click events
	change.click(function(){
		//show the loading bar
		showLoading();
		//load selected section
		if(this.id == "home")
		{
			change.load(this.className='current-page');
			content.slideUp();
			content.load("pages/index.php", hideLoading);
			content.slideDown();
		}
		else if(this.id == "secondpage")
		{
			change.load(this.className='current-page');
			content.slideUp();
			content.load("pages/secondpage.php", hideLoading);
			content.slideDown();
		}
		else
		{
			//hide loading bar if there is no selected section
			hideLoading();
		}
	});

	//show loading bar
	function showLoading(){
		loading
			.css({visibility:"visible"})
			.css({opacity:"1"})
			.css({display:"block"})
		;
	}

	//hide loading bar
	function hideLoading(){
		loading.fadeTo(1000, 0);
	};
});

Heres the structure of the menu/content
Code:

<ul id="menu">
<li><a id="home" class="normal" href="#Home"></a></li>
<li><a id="secondpage" class="normal"  href="#Secondpage"></a></li>		
</ul>

<div id="content">
<ul id="sec-menu">
<li><a id="link1" class="normal" href="#">Link1</a></li>
<li><a id="link2" class="normal"  href="#">Link2</a></li>		
</ul>
</div>

Heres the code that jquery history plugin uses in demo for ajax
Code:

jQuery(document).ready(function($) {
        function load(num) {
            $('#content').load(num +".html");
        }

        $.history.init(function(url) {
                load(url == "" ? "1" : url);
            });

        $('#ajax-links a').live('click', function(e) {
                var url = $(this).attr('href');
                url = url.replace(/^.*#/, '');
                $.history.load(url);
                return false;
            });
    });

i keep getting the error

GET http://code.jquery.com/jquery.min.map net::ERR_TOO_MANY_REDIRECTS
& Failed to load resource: net::ERR_TOO_MANY_REDIRECTS

when i load my page...and the havascript doesn't work properly on ym page...how do i resolve this.

thanx in advance

var s="attr"
var i=$(s)
// jQuery(elem).attr(attr,eval("elm"+attr));
jQuery(elem).$(s)(attr,eval("elm"+attr));//i tried this.

how to assign a variable name in the above code(in place of s) so that i need to add an attribute to the element "elem".

Ok, I would post my entire data here but then yall would be reading insane amounts of script. I've got a div content jquery slider on my site I am making and it works beautifully in all browsers(took me a while). Then, I decided why not have it where when people click on a "read more" link that it pops up a box, instead of directing to the new page, and displays the contents of a div. It would not work at all. My question is there a possible way to do this?

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 was working on a tutorial for some ajax uploading stuff and I ran across a new function syntax I don't recognize. I am not a Javascript pro, but I am not a newbie either. here is the code I am working on:

Code:

		function handleFileSelect(e){
			var files = e.target.files;
			var output = [];
			for(var i=0,f;f=files[i];i++){
				if(f.type.match('image.*')){
					var reader = new FileReader();
					
					reader.onload = (function(theFile){
						return function(e){
							var span = document.createElement('span');
							span.innerHTML = ['<img class="thumb" src="',e.target.result,'" title="',theFile.nbame,'" />'].join('');
							document.getElementById('list').insertBefore(span,null);
						};
					})(f);
					
					reader.readAsDataURL(f);
				}
			}
			document.getElementById('list').innerHTML = '<ul>'+output.join('')+'</ul>';
		}
		document.getElementById('files').addEventListener('change',handleFileSelect,false);

To be a little more clear, the code in question is that is the very middle. The syntax I don't understand is:

Code:

class.event = (function(arguments){
     //stuff you put in a function...
})(more Arguments?);

I tried to customize a simple one to learn for myself and I wrote this:

Code:

var a = 'A';
var b = 'B';

test = (function(t){
     alert(t);
     alert(b);
})(b);

test(a);

The browser would alert 'B' and that's it. The console would tell me that 'test is not a function.' OK, so I am confused.

The topmost code works. What I am wondering is what the syntax is called for creating a function (or event listener?) that way, and how it works. Although if I new what it was called I could just google how it works.

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!

I found this script, and it works great:
Code:

<script type="text/javascript">
  function disable(element)
  {
    var input = document.getElementById(element).getElementsByTagName("input");
    for(var i = 0; i < input.length; i++)
    {
      input[i].setAttribute("disabled","true");
    }
  }
</script>

I tried to make the inverse by simply reversing the setAttribute() like so:
Code:

<script type="text/javascript">
  function enable(element)
  {
    var input = document.getElementById(element).getElementsByTagName("input");
    for(var i = 0; i < input.length; i++)
    {
      input[i].setAttribute("disabled","false");
    }
  }
</script>

But that didn't do it.
Can someone show me why, and how to fix it?

Here's the sample form which I'm trying to test it on:
Code:

<form>
  <input type="radio" name="test" onclick="disable('D1')" /> disable<br/>
  <input type="radio" name="test" onclick="enable('D1')" /> enable<br/>
  <fieldset id="D1">
    <input class="" type="text" value="test value1" /><input class="" type="text" value="test value2" /><br/>
    <input class="" type="text" value="test value3" /><input class="" type="text" value="test value4" /><br/>
    <input class="" type="text" value="test value5" /><input class="" type="text" value="test value6" /><br/>
  </fieldset>
</form>

Edit:
The ultimate goal which I'm working toward now (step by step =) is to have a form more like:
Code:

<form>
  <input type="radio" name="test" onclick="disable('D1')" />
  <fieldset id="D1">
    <input class="" type="text" value="test value1" /><input class="" type="text" value="test value2" />
  </fieldset>
  <input type="radio" name="test" onclick="disable('D2')" />
  <fieldset id="D2">
    <input class="" type="text" value="test value3" /><input class="" type="text" value="test value4" />
  </fieldset>
  <input type="radio" name="test" onclick="disable('D3')" />
  <fieldset id="D3">
    <input class="" type="text" value="test value5" /><input class="" type="text" value="test value6" />
  </fieldset>
</form>

And have the fieldsets enable and disable according the selection of the radio buttons.

Also, the fieldsets (and their ID's) will be dynamically generated via PHP

Hi All, I'm trying to convert an anonymous function to a real function (nesting is getting out of hand), however the msg object becomes undefined after conversion. Here is the converted anonymous function which fails: https://gist.github.com/2587613 and here is the original anonymous function which works: https://gist.github.com/2587667

Any help would be greatly appriciated
