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?

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 :: Conditionally Looping Through Array - Determine If The Function That Runs The Ajax Call Has Succeeded Or Not?

Oct 11, 2011

I've got an array of names, and one ID. I need to run an ajax call using the ID and each lastname, until I get a successful hit on the ajax call. I can't quite figure out how to determine if the function that runs the ajax call has succeeded or not, it always returns false for me... Here's the code for the loop:

Text Revealing - When Mouse Is Not Over The Click-button A Text Should Be Displayed At The Right Of The Button

Jun 2, 2010

I'm looking for a javascript/css code that can do the following, for a click button:

- When mouse is not over the click-button, a text should be displayed at the right of the button, in a bordered textbox - 85% transparency (hardly visible)

(- when mouse hovers over the button, the button image changes to a different one <- I know how to do this)

- When the button is clicked the text shows up normaly (0% transparency)

- When clicking again the button OR anywhere else on the page, the text goes back to 85% transparency.

Ajax :: Button Eating My Lunch - And Dynamically Added Button

May 22, 2010

The main page is called Aj.html. In the 'head' I have mostly some functions to support Ajax call to server PHP (to just 'echo' something so I could see Ajax work). In the 'body', there is a little javascript and a form 'button'. When I click the button, an 'onclick' event causes a function to do the last step or two of the Ajax stuff... and the server PHP element is called... and then my ajax message handler back in Aj.html gets control to just send an alert... and that was the initial experiment ... and it was just so I could see how Ajax works.

Well - then I noticed that the 'button' is only clickable ONE time... And I set about to try to learn whatever I needed to learn to make that button be one that could be used to fire off the Ajax stuff multiple times... But I couldn't get that to work. So, I tried some code to remove the onclick event (during the ajax messaging handling logic in Aj.html) - and then add another onclick event to that same button... but that didn't work. Then, I tried to delete my button altogether - and insert a new button with it's own 'onclick' (which also would fire the ajax stuff) - but that didn't work, either....

Anyway... Now, my biggest curiosity (for the moment, at least) is why I can't dynamically add a button that has the needed onclick stuff to also fire the Ajax stuff... So, I guess I'd like to solve that right now.

What's currently happening is this: when I'm in the part of the code that is defining the dynamic button - and just before that button is added to the form, I define the 'onclick' that is supposed to be a part of that new button... BUT - when that assignment is made, it is almost like javascript is thinking that the request is actually in insert another onclick for the in-progress 'click'... because the new onclick is immediately processed at that point (I don't even make it to the next statement...just boom... the new onclick function is executed).

Also - the new dynamically added button DOES get added okay... but when I click that newly added button, it doesn't fire the Ajax stuff it's supposed to fire (via the onclick for this added button) - instead, it just causes what appears to be like a page refresh ... because the regular button reappears at that point (and then the Ajax stuff will again work off of that 'regular' button).

I'm including the whole script here.

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:

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.

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 :: 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.

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?

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

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...

<html>

<link href="timer.css" rel="stylesheet" type="text/css" />

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?
