JavaScript - Function Converturl() Help Or Suggestions

I have a search box on my website, that gets users from my database using php. And uses Javascript to display suggestions as the users type. What I'd like to be able to is to use the arrows to toggle down through the different suggestions. Any ideas how I would go about doing this?

Here's the javascript part of the code:
Code:

function createObject() {
	var request_type;
	var browser = navigator.appName;
	if(browser == "Microsoft Internet Explorer"){
	request_type = new ActiveXObject("Microsoft.XMLHTTP");
	}else{
		request_type = new XMLHttpRequest();
	}
		return request_type;
}

var http = createObject();

/* -------------------------- */
/* SEARCH					 */
/* -------------------------- */
function autosuggest() {
q = document.getElementById('search-q').value;
// Set te random number to add to URL request
nocache = Math.random();
http.open('get', 'lib/search.php?q='+q+'&nocache = '+nocache);
http.onreadystatechange = autosuggestReply;
http.send(null);
}
function autosuggestReply() {
if(http.readyState == 4){
	var response = http.responseText;
	e = document.getElementById('results');
	if(response!=""){
		e.innerHTML=response;
		e.style.display="block";
	} else {
		e.style.display="none";
	}
}
}

As it is, I'm using Walter Zorn's JS Graphics Library in an attempt to write a small screensaver-type-thing for jailbroken iPhones/iPod touches. However, on my mom's AMD Athlon 64 3000+, the drawing gets pretty laggy, so you can imagine how utterly choppy it is on my iPod. The look I'm going for is the Windows XP Mystify screen saver, with corners bouncing around the screen. So, my first question is this: are there any alternatives for this sort of thing, short of manually generating a video, gif, or multiple images to switch through, or is there any way to make my code more efficient for the CPU? (Code below)

NOTE: I know I could make it look a lot nicer by making a 'corner' class, and having each corner be an object (and even nicer by using an array of 'corners'). But I'm not sure that would help the CPU's calculations much, and make the code more efficient as a whole.

Code:

<div id="Mystify">
			<script type="text/javascript">

Please keep in mind, there's a LOT of repeat code, so you only have to read any one part once. To test/see/use the code, you'll need to download wz_graphics.zip. Then download the attached txt file to the same directory as the unzipped wz_graphics, change it to .html instead of .txt, and open it.

Hello,

I have an existing php contact form which incorporates php validation (required name with only characters, valid email address format, and minimum message length) and re-captcha.

I would like to add some "real time" validation to the fields on my form (there are 3 fields - name, email and message) before the "Submit" button is pressed. For example when the user tabs from one text box to the next but hasn't filled in the required information.

I am totally new to any type of java, but am I right in thinking I need either JavaScript, Ajax or JQuery to perform real-time validation?

If so, which should I be looking into and are there any basic examples of form validation?

I want to keep my pup validation as I'm aware that php is client-side but still needed as people can turn Java off in their web browsers.

Any tips and pointers will be very much appreciated!

Thankyou,

Tom

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.

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

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!

while running the application i am getting an error incase if the data is string ex:if data is 'image1' i am getting an error, but with number there is no problem ex: if data is '1122'.

this is very urgent to solve this problem plz any one help me

I made a mouseover event of a caption on a picture, when I hover the opacity of the background color of the hover and the text goes down. What I want is that when I hover over the image which the caption is floating on, the onmouseover event gets activite. For an imaginary example:
Code:

function unhighlight(x) {
x.style.backgroundColor="transparent"
}

Function ActivationFuction()
{
activate.function="unhighlight"
}

thanks

Thank you in advance if someone can help. I have been banging my head against the wall for hours now.

Here is the code:

Code:

for (var i = 0; i < BS_crm['activityTypes'].length; i++) {
        var clickFunc = function(){ activityList.showForm( -1, {blockType:[""+BS_crm['activityTypes'][i]['id'], "0"]} ); };
        var type = {
                value: BS_crm['activityTypes'][i]['id'],
                label: "Add New "+BS_crm['activityTypes'][i]['label'],
                css: BS_crm['activityTypes'][i]['css']+"_16",
                onClick: clickFunc
        };
        previewLinks.items.push( type );

}

Now, basically what I am doing here is running through one array to
create an array of objects, that will be used to create links that
will use whatever onClick function I pass it. The problem is that on
the second line I need the BS_crm['activityTypes'][i]['id'] to be a
value, not a reference. If that line was simply changed to:

Code:

var clickFunc = function(){ activityList.showForm( -1, {blockType:["3", "0"]} ); };

then everything would work as I need.

How can I make this happen? I would really appreciate any help.

Thank you again in advance.

How can I call a PHP Function inside a Javascript Function? This is what I have so far, but I don't think I'm doing it the right way.
Any suggestions?

PHP Code:
<?php
function phpQuery(){

     $query = mysql_query("INSERT INTO mytable VALUES('','name','email')");

}
?>
<script type="text/javascript">
function delayQueries()
{
  timeoutID = window.setTimeout(doQueries, 2000);
}

function doQueries()
{
  var runQuery = "<?php phpQuery(); ?>";    
}
</script>

I'm trying to "progressively enhance" one of my surveys using javascript. Basically, I have rating scales that make use of radio buttons as each point on the scale. Each radio button occupies its own cell in a table. I wrote some functions that will highlight cells on mouseover in a color corresponding to its position on the scale (e.g. the lowest point is red, the midpoint is yellow, the highest point is green). When a radio button is clicked, the background of the button's cell and preceding cells in the same row will be colored accordingly. The functions are working well in FireFox and Chrome (I just have to add a few lines using the addEvent function to make it compatible with IE).

The effect looks a lot nicer when I add a function that makes the visibility of the radio buttons hidden.

However, I want to make sure that there is a fallback option in case the functions that color the cells don't work for whatever reason. I would not want the radio buttons hidden in this case.

Is there a method whereby I can call the "hideRadiobuttons" function only if the other functions are successfully executed?
