Function Only Runs 33 Percent Of Time When Called?

Feb 23, 2010

function update(value1){
doAjax("behind_scan.php" , "id="+value1);
}function doAjax(url , str ){
xmlhttp=GetXmlHttpObject();
if (xmlhttp==null){
alert ("Browser does not support HTTP Request");
return;
}url=url+"?"+str;
xmlhttp.onreadystatechange=stateChanged;
xmlhttp.open("GET",url,true);
xmlhttp.send(null);
}function stateChanged(){
if (xmlhttp.readyState==4){
//document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
//alert(xmlhttp.responseText)
document.forms.myform.scanner.value = "";
document.forms.myform.scanner.focus();
}}function GetXmlHttpObject(){
if (window.XMLHttpRequest){
// code for IE7+, Firefox, Chrome, Opera, Safari
return new XMLHttpRequest();
}if (window.ActiveXObject){
// code for IE6, IE5
return new ActiveXObject("Microsoft.XMLHTTP");
} return null;
}

This pages calls a function on a separate php page to run 2 mySQL queries, the value must be put in the text 3 times in quick succession before the database is altered. I've tried all the other functions and they seem to be fine, AJAX is my weakness but I need it for the main functionality of my website. I need this to work.

Get An Audible Click Sound File To Run Every Time The Function Runs

Apr 27, 2011

I have a self project I am exploring. I would like to play a simple sound file each time a function is run. The function runs every second, so, basically, I am just trying to get an audible click sound file to run every time the function runs. I do not know how to play a sound file thru javascript. Here is the code file thus far...

<link href="timer.css" rel="stylesheet" type="text/css" />
<embed src="click.wav" autostart=false hidden=true name="sound1" enablejavascript="true">

Event Code Runs Twice?

Feb 23, 2010

Does anyone know why these event codes run twice? E.g. I am using a cookie to keep track of [Ctrl] + [Shift] + [F] by incrementing a variable once everytime it is used. However the code for it runs twice and thus the variable is never odd as it always increments by two.It's the same for the other events, such as [Ctrl] + [Shift] + [S], it runs twice. This was not occuring when I first inserted the cookie code last week. I have read about "bubbling" but I cannot seem to stop the code running a second time.EDIT: Internet Explorer (6+) is only browser code needs to work in.

document.addEvent('keydown', function(event) {
var event = new Event(event);
if (event.key == 'f' && event.control && event.shift) {

Expandable Menu That Runs Sql?

Aug 3, 2010

I'm trying to put together this expandable menu that runs sql (using javascript and php). I've got the code below but I'm horrible with javascript and I can't get two things to work.I cannot figure out how to use the closall() function so that when the page opens all selections are closed.I'm trying to get the mouseover colors and clickable areas and the only way I know how to do that is with a table so I thought I'd put a quick table in between the <li> but can't figure out the whole onClick= to incorporate the # so that I can get rid of the <a href> tag part...

Code:
<?php
require("connect.php");

Code Runs Slower In IE9 Than IE8

May 14, 2011

I'm having difficulty in explaining why the following code runs slower in IE9 than IE8! (Testing in Win 7 IE9 both 32 bit and 64 bit running in VMWare 3 virtual machine on OS X 10.6.7)

Here's some test code that runs smoothly in about half a second in (latest) FF/Chrome/Safari on OS X, WinXP, and Win7 plus IE7 & 8 on WinXP (for simplicity I removed the tweak that makes it work in IE6).

For some reason I can't explain, it's awful in IE9, slow and clunky. Reducing the time for the setTimeout makes it a bit quicker but no less jerky.

I've tried removing and benchmarking a number of what might be the choke points (Math.min for example ... all with no change.

Here's the test code ...

IE: Object Expected; Moz: Runs Fine

Jul 20, 2005

I have a html document, in which I include two standard libraries of
functions (supposed to help me with cross browser issues), and one
application-specific script file. All Javascript fcoz.

The very first attempt at invoking a function from this last script file
fails miserably in IE (6) but works as it should in Moz (1.4)

I have tried putting alert()s here and there, so I (think I) can tell
the exact spot where IE dies.

Structure is like this (all in HEAD):

<script type="text/javascript" src="../libPlatform.js"></script>
<script type="text/javascript" src="../libDOM.js"></script>
<script type="text/javascript" src="tooltip.js"></script>
<script type="text/javascript">

function register() {
initAPI();
alert('after init');
regTooltip('a1');
alert('after dreg-1');
regTooltip('a2');
}
</script>

initAPI sits in libPlatform, and executes. I get to see the first alert.
And then, boom, IE script errors on page: Object expected (points to
'regTooltip')

Am I missing something here? If my code is wrong, why is Mozilla so
forgiving about it? How can I persuade IE to get the function?

Note: if I put regTooltip() right above register(), so locally in the
document, it works.

JQuery :: Effect Only Runs Once, Won't Repeat?

Mar 4, 2011

I'm making a website at [URL].. and I'm trying to create a menu using Jquery 1.3.2. Anyways, if you look at the tabs in my header, they have an effect but it only works once. After I mouse over the same tab a second time, they do not animate. I also have a similar menu at [URL].. You may notice the second menu also will fade to a darker gray. If i copy and past that code into my drupal block, it will still only animate one time. Do i need to include something extra because its version 1.3.2??? I also have another Jquery plugin below the header which is called a S3SLIDER. I'm not calling the jquery script up more than once.Here's the code for the Jquery menu at adc-design.com:

AJAX :: Only Runs Once With Php Displayed Button

Feb 1, 2011

my AJAX is working in FF and Opera just fine, As in it repeats the function whenever the button is clicked, but in IE the first click works, but then it doesn't repeat...I've been searching around form some fixes, and found quite a lot but none of it seems to work [as you can see i've tried adding '.live' but still nothing]

Heres' the code:

<script type="text/javascript">
$(document).ready(function(){

[code]....

This is currently at the top of my index.php, but the button to run this function is echoed by php which I feel may have something to do with it?

Having A Link Which Runs A Js Function (acceptable To Have No Href?)

Jul 17, 2006

question: if you want a link which simply runs a js function is it acceptable to have no href? the problem with this is the cursor doesnt change when you hover over, but if you put # as the href it jumps to the top of the screen which is sometimes unacceptable. what it the best solution to this? granted you could do event handling behind the scenes and just intercept the clicks and prevent the href from going anywhere, but sometimes you just want to stick an onclick on the anchor tag!

JQuery :: Function Runs Before HTML Updated By Ajax

Aug 21, 2011

Problem in the timing of the script. The problem is that when I try to get an id of an object that was added by ajax, the script doesn't recognize it. The html:
<select id="categories" name="categories">
<option value="3">aa</option>
<option value="43">bbb</option>
</select>

When I load the page, there is this script that get the value of the #categories and use ajax to fill another select and in the same ajax, I load images by another function using the new select input that was created:
function fill_subcategories(){
parent=$("#categories").val();
$.ajax({
type: "post",
url: "ajax/sub_galleries.php",
data: 'parent='+parent,
success: function(data){
$('#sub_categories').html(data);
}});
show_exist_imgs()
}

This fills this div:
<select name="sub_categories" id="sub_categories"></select>
Right after filling the #sub_categories, I use another ajax that get images of the new id of the #sub_categories, and here I get the problem.. the js:
function show_exist_imgs(){
g_id=$('#sub_categories').val();
$.ajax({
type: "post",
url: "ajax/show_exist_imgs.php",
data: 'g_id='+g_id,
success: function(data){
$('#exist_files').html(data);
}});
}
This script doesn't recognize the id of the new $('#sub_categories') select input.. why is that?

JQuery :: Check Event Layout - Function Runs Twice

Nov 4, 2009

I have created some code that alerts me the contents of all the child divs inside a main div

function CheckEventLayout(){
//check all divs in area and resize overlapping divs
var RunOnce;
if( RunOnce != true ){
var StartTimes = new Array();
var EndTimes = new Array();
var i = 0;
$("div#day-view-overlay").children("div.day-view-appointment").each(function(){
var DoOnce;
if( DoOnce != true ){
alert($(this).html()); .....
CheckEventLayout();

The problem is this code is on a page that is loaded via post and if you go off the page and then back onto it jquery seems to attach the function again so it runs twice. So need to unbind this function before the script runs again.

Same Image. Onload Runs Again Changing Style.Width!

Aug 27, 2005

I change image.style.width inside a image.onload function. And surprisingly, I found that it runs the onload function on the same image again with the new style.width value. Javascript treats this as a new image! This is the same old image.

Is there a way to pervent it from runing onload the second time?

JQuery :: Search Function Runs Multiple Times When Grouped

Dec 19, 2010

If this search function is included in an include file with other functions it will run more than once if you click another function first, then come back to it to do another search.

Code:
$(document).ready(function() {
$("a#searchowner").click(function() {
var searchval=$("#p1").val();
alert(searchval); //test alert box
$.post("findowner.php", {p1 : searchval}, function(data){
if (data.length>0){
$("#ownerIDdiv2").html(data);
}});
});
}); //end

For example if I click the next page function, then decide to click for a new search it runs more than once:
Next page function:

Code:
$(document).ready(function() {
$('a#nextpage').click(function() {
var page = $(this).attr('page');
var searchval = $(this).attr('schval');
var maxpage = $(this).attr('maxpage');
$.post("findowner.php", {
p1 : searchval,
page : page
}, function(data){
if (data.length>0){
$("#ownerIDdiv2").html(data);
} });
});
}); //end

However, if I put the first search function in a separate include file all works perfect. Why it runs multiple times if it is grouped among other functions?

'this' And SetInterval

Nov 23, 2005

If I have some code that's a bit like this

Con = function() {
this.op = 1;
this.count = 0;
}
Con.prototype.loop = function() {
this.doNext = setInterval(this.next, 100);
}
Con.prototype.next = function() {
this.count++;
if (this.count > 10) clearInterval(this.doNext);
}

obj = new Con();

when I call obj.loop(); 'this' in obj.next refers to setInterval
and not obj . I realise I can add var ref = this; and send it with
setInterval but is there something I can do to get 'this' to refer to
obj when in obj.next?

SetInterval() Help

Feb 8, 2006

I'm attempting to create a small function that when called upon will change the CSS background property 10 times at 80 millisecond intervals. I'm pretty sure setInterval() is the way to go about this, but I've been toying with my script for an hour and can't get anything to work.

At each 80 millisecond interval, the CSS background property should change like so:

background: url("image.png") 0 0 no-repeat;
background: url("image.png") 0 20px no-repeat;
background: url("image.png") 0 40px no-repeat;
background: url("image.png") 0 60px no-repeat;

and so on.

I would normally just use the background-position property, but it seems the hyphen throws javascript for a slip. It's really not necessary for this function, but if there's a way to use hyphens, it would be good to know for future reference.
