JavaScript - Ie Won't Remove Spinning "in Progress' Icon
Hello,
I have a tool in my app where a user can perform a search, and it will use AJAX to deliver the results into a small box, in JSON format. When a user submits a search, a spinning gif will appear as the query is running. A javascript function is then meant to remove the gif and display the results once ready. In IE, however, this fails to happen, and the gif is locked in place, preventing the results from being displayed. I have no experience with javascript and am a bit unsure what to do. Tried to use IE's script debugger, but got totally confused. The script is much longer than this, but I think this is the problematic area: Code: 'beforeSend': function(r) {
ul.find('li').remove();
ul.html('<li class="center"><img src="/images/ajax-loader.gif" /></li>');
},
'success': function(r) {
ul.find('li').remove();
h = ''
$(r).each(function(k,r0){
h = h + '<li data-id="'+r0.value+'" data-icon_url="'+r0.icon_url+'">'+r0.label+'</li>';
});
For some reason, in IE only, it will clear the contents and display the gif upon submitting a search. But then it won't clear the gif and display the results. Any ideas? I would be so appreciative. Thank you. Greg Similar Tutorials----------SOLUTION---------- ----------ORIGINAL PROBLEM---------- The second line of code. What does it do? It's confusing because it doesn't have a semicolon at the end and it doesn't end with (). Code: var centreicon = new GIcon(); centreicon.constructor centreicon.image = "http://maps.google.com/mapfiles/kml/pal3/icon31.png "; centreicon.shadow = "http://maps.google.com/mapfiles/kml/pal3/icon31s.png "; centreicon.iconSize = new GSize(12, 20); centreicon.shadowSize = new GSize(22, 20); centreicon.iconAnchor = new GPoint(6, 20); centreicon.infoWindowAnchor = new GPoint(5, 1); I found this on stackoverflow while trying to find a way to make my own icons on a map. With that being said. I'm still confused about how to apply the new graphic to a map. I don't see how they apply that picture to a coordinate. Does anyone know how to do that? Can I do this? Code: var centreicon = new GIcon(); centreicon.constructor centreicon.image = "http://maps.google.com/mapfiles/kml/pal3/icon31.png "; centreicon.shadow = "http://maps.google.com/mapfiles/kml/pal3/icon31s.png "; centreicon.iconSize = new GSize(12, 20); centreicon.shadowSize = new GSize(22, 20); centreicon.iconAnchor = new GPoint(6, 20); centreicon.infoWindowAnchor = new GPoint(5, 1); var marker = new GMarker( new GLatLng(-34.397, 150.644) , centreicon); map.addOverlay(marker); -------- A tad bit later -------- So this is the code I have on my testing site Even thought I'ved defined the the icon's image and location It does not show up on the map. What am I missing? Code: <!DOCTYPE html>

I am asking a pretty simple question, but you got to start learning somewhere, you know! Anyway, I have implemented a script that resizes images into small thumbs on the left side of a page and shows the full size image on the right when the user click on a thumb. It works well. However, I have a possible 10 thumbs on theleft and my database that feeds this does not always have 10 images. Since I re-use the page for mutiple listings, I need to find a way to disable the broken image link for listings that don't have 10 thumbs. I have attached a picture of what it looks like. Here is the script: Code: #jgal { list-style: none; width: 200px; }
#jgal li { opacity: .5; float:left; display: block; height:60px; width:60px; overflow:hidden; background-position: 50% 50%; cursor: pointer; border: 3px solid #fff; outline: 1px solid #ddd; margin-right: 14px; margin-bottom: 14px; }
#jgal li img { height:60px; width:auto; }
#jgal li.active img { display: block; }
#jgal li.active, #jgal li:hover { outline-color: #bbb; opacity: .99 /* safari bug */ }
/* styling without javascript */
#gallery { list-style: none; display: block; }
#gallery li { float: left; margin: 0 10px 10px 0; }
</style>
<!--[if lt IE 8]>
<style media="screen,projection" type="text/css">
#jgal li { filter: alpha(opacity=50); }
#jgal li.active, #jgal li:hover { filter: alpha(opacity=100); }
</style>
<![endif]-->
<script type="text/javascript">document.write("<style type='text/css'> #gallery { display: none; } </style>");</script>
<!--[if lt IE 6]><style media="screen,projection" type="text/css">#gallery { display: block; }</style><![endif]-->
<script type="text/javascript">
var gal = {
init : function() {
if (!document.getElementById || !document.createElement || !document.appendChild) return false;
if (document.getElementById('gallery')) document.getElementById('gallery').id = 'jgal';
var li = document.getElementById('jgal').getElementsByTagName('li');
enlargedImg = document.createElement('img');
document.getElementById('jgal').parentNode.insertBefore(enlargedImg,document.getElementById('jgal').nextSibling);
enlargedImg.src = li[0].getElementsByTagName('img')[0].src;
li[0].className = 'active';
for (i=0; i<li.length; i++) {
li[i].style.backgroundImage = 'url(' + li[i].getElementsByTagName('img')[0].src + ')';
li[i].style.backgroundRepeat = 'no-repeat';
li[i].title = li[i].getElementsByTagName('img')[0].alt;
gal.addEvent(li[i],'click',function() {
var im = document.getElementById('jgal').getElementsByTagName('li');
for (j=0; j<im.length; j++) {
im[j].className = '';
}
this.className = 'active';
enlargedImg.src = this.getElementsByTagName('img')[0].src;
});
}
},
addEvent : function(obj, type, fn) {
if (obj.addEventListener) {
obj.addEventListener(type, fn, false);
}
else if (obj.attachEvent) {
obj["e"+type+fn] = fn;

obj.attachEvent("on"+type, obj[type+fn]);
}
}
}
gal.addEvent(window,'load', function() {
gal.init();
});
And then my list basically looks like this: Code: <ul id="gallery">
<li><img src="images/details/<?php echo $row_WADAitems['ItemThumb5']; ?>" alt="<?php echo $row_WADAitems['ItemDesc5']; ?>"></li>
<li><img src="images/details/<?php echo $row_WADAitems['ItemThumb6']; ?>" alt="<?php echo $row_WADAitems['ItemDesc6']; ?>"></li>
<li><img src="images/details/<?php echo $row_WADAitems['ItemThumb7']; ?>" alt="<?php echo $row_WADAitems['ItemDesc7']; ?>"></li>
<li><img src="images/details/<?php echo $row_WADAitems['ItemThumb8']; ?>" alt="<?php echo $row_WADAitems['ItemDesc8']; ?>"></li>
<li><img src="images/details/<?php echo $row_WADAitems['ItemThumb9']; ?>" alt="<?php echo $row_WADAitems['ItemDesc9']; ?>"></li>
<li><img src="images/details/<?php echo $row_WADAitems['ItemThumb10']; ?>" alt="<?php echo $row_WADAitems['ItemDesc10']; ?>"></li>
<li><img src="images/details/<?php echo $row_WADAitems['ItemThumb11']; ?>" alt="<?php echo $row_WADAitems['ItemDesc11']; ?>"></li>
<li><img src="images/details/<?php echo $row_WADAitems['ItemThumb12']; ?>" alt="<?php echo $row_WADAitems['ItemDesc12']; ?>"></li>
<li><img src="images/details/<?php echo $row_WADAitems['ItemThumb13']; ?>" alt="<?php echo $row_WADAitems['ItemDesc13']; ?>"></li>
<li><img src="images/details/<?php echo $row_WADAitems['ItemThumb14']; ?>" alt="<?php echo $row_WADAitems['ItemDesc14']; ?>"></li>
</ul>
So as you can see, if I don't have an image in the database that it pulls from, I get that icon for a broken image link. How can I remove that icon so it doesn't show the no image icon? Many thanks! Is there a way to remove (not disable and not delete) an option in a "select" list, and restore it later when needed? I have a form with many huge lists ("select" with many "options") that depend on eachother. I am dynamically updating the form through server, and wish to update the list values by sending a mask string. This way I could remove and restore the options without the need to pass the whole list again. I tried many ways but none work: * option.diabled="disabled" is not good because it is still shown * option.style.visibility='hidden' is not good because it is still taking a row * option=null is not good because I will not be able to restore it I need a method similar to the following one for remove/add fields in a form: remove: <field>.style.display='none'; resto <field>.style.display=block'; Thank you!!! Hi, The following code adds an element to a page when a new address is inputted. Is there a way to remove all added elements with a Clear All button? I have a "Clear All" button with id="ClearAddresses" but I don't know how to remove all created elements - the code here only removes one at a time, since the element is created when the "Search" button is clicked.

Is there any javascript regex to remove the html comments, i want to be able to view what it is in the comments. if <!-- comment here --> will become "comment here" thx! Hi - firstly, apologies for the generic nature of this question, I'm sure I will have some more specific questions later into this project! I'm a complete newbie to javascript and would like to know if it is possible to create a vertical spinning bar like on a fruit machine, that contains a number of images. I would like the bar to have the following behaviour. 1. on the mouse being above the centre point of the bar, the images scroll upwards 2. on the mouse being below the centre point of the bar, the images scroll downwards 3. the further you are from the centre point - the faster the bar scrolls 4. when you hover an image - the bar stops, the image lightens a shade and a link is displayed below the image. My initial thought is to contain the bar in a div and have javascript actions applied to it depending on the mouse position within the div - the actions will change the positions of the image contained in the div. Would be great if anyone knew some code that does a similar thing - or could give me some pointers to start me off. Thanks : ) Hello, can this upload progress windowsbar be made to close or stop at 100%? In the upload page the javascript code: Code: <script language="JavaScript">
function input(ok)
{
var M1=ok.upload_author.value;
if (M1=="") {
alert("Author is empty!");
return false;
}
M1=ok.upload_title.value;
if (M1=="") {
//alert("File Description is empty!");
//return false;
}
if (ok.UploadedFile.value=="") {
alert("File is empty!");
return false;
}
var sCheckType="%checktype";
if(sCheckType=="1")
{
M1=ok.UploadedFile.value.toLowerCase();
var pos=M1.lastIndexOf('.',M1.length);
var sExt;
if(pos>-1)
sExt=M1.substr(pos+1);
var sType="%filetype";
pos=sType.indexOf(sExt);
if(pos>-1)
{
alert("This type of file cannot be uploaded!");
return false;
}
}
ok.uploadid.value=Math.round(Math.random()*100000000);
return true;
}
function onstopupload() {
if(document.post.uploadid.value=="") return;
window.("uploadstop.ghp?uploadid="+document.post.uploadid.value+"&vfolder="+document.tempform.vfoldername.value) ;
}
function onshowprogress() {
if(document.post.uploadid.value=="") return;
window("showprogress.ghp?uploadid="+document.post.uploadid.value+"&vfolder="+document.tempform.vfoldername.value) ;
}
</script>
Then the "Show progress" button which on clik opens in a new window. Code: <input name="Upload" type="submit" class=button value="Upload">
</font>
<input name="stopupload" type="button" class=button id="stopupload" value="Stop" onClick="onstopupload()">
<input name="showprogress" type="button" class=button id="showprogress" value="Show upload progress" onClick="onshowprogress()">
And here;s the code from the Progress window. Code: <strong>Incarcare %filename...
<br>
%progress%
<br>
<table width="50%" border=1 align="center" cellpadding=0 cellspacing=0>
<tr>
<td bgcolor="#FF0000" width="%used%" height=15 style="border:0"> </td>
<td bgcolor=white width="%left%" height=15 style="border:0"> </td>
</tr>
</table>
<br>
<a href="showprogress.ghp?uploadid=%uploadid&vfolder=%vfolder">Actualizeaza</a>
<a href="uploadstop.ghp?uploadid=%uploadid&vfolder=%vfolder">Stop</a>
Plese if anyone knows how to resolve this to pop-up in a window and when it reachis 100% to stop redirecting, or to close it self or by user. Thanks in advance. Cira Marius Hey guys! I have a progress bar written in javascript. Its pretty simple, consisting of a couple divs, where the inside one grows with the given percentage. Anyways, the problem we are having is that sometimes the percentage that is dynamically calculated is over 100% (we are using it as an job completion progress bar, so if more hours are spent than estimated the bar will be over 100%. I guess thats fine, except the inside div goes right off the container and keeps growing. Can we make the inside div max out at 100% somehow? Hoping someone can help me out with this, im not sure how this can be done! I should add that the original script with example I found he alpinemeadow.com/stitchery/weblog/HTML-morsels.html Here is the original code: Code: <script language="javascript">
function drawPercentBar(width, percent, color, background)
{var pixels = width * (percent / 100);
if (!background) { background = "none"; }
document.write("<div style=\"position: relative; line-height: 1em; background-color: "
+ background + "; border: 1px solid #979797; width: "
+ width + "px\">");
document.write("<div style=\"height: 1.5em; width: " + pixels + "px; background-color: "
+ color + ";\"></div>");
document.write("<div style=\"position: absolute; text-align: center; padding-top: .25em; width: "
+ width + "px; top: 0; left: 0\">" + percent + "%</div>");
document.write("</div>"); }
</script>
Called for he Code: <script language="javascript">drawPercentBar(171, <%=totaltotal/EstHours*100%>, '#aadba2', '#F2F2F2'); </script> I am trying to manipulate a an image gallery that functions well. Now, I have the ability to pull information from a user's preference pannel and need to place it in the an href="" // And other information in each of the "src" | "url" | "alt". Any ideas would be truly helpful. This is what I am working with at the moment and it doesn't work (obviously because it is adding code inside a span). Here is what I am starting from: [CODE] var title01Span = document.getElementById('title01Span'), //Finds the id that I want prefs = new gadgets.Prefs(), // Pulls from the user's preferences yourtitle01 = prefs.getString("title01"); // Pulls the correct string from those preferences title01Span.innerHTML = yourtitle01; // replaces the span.id with that text but I need to be able to do this in the src / href / url / etc. [CODE] Thank you so much! I seriously could use as much help as possible! Hi! I use the :: Form field Progress Bar from DynamicDrive: Form field Progress Bar Now I trided to change the text when the textarea is full "Limit:100%" to "Your max. characters is reached" I trided it but with no luck.

I'd like to have a bar at the top of my page (if you need an example, something simliar to FedEx to show where you package is along the way) that will get updated upon each page move so the user knows how far along they are in the process and how much farther they have to go? Any type of tutorials or ideas (whether it's PHP and jQuery or any other combination) I'd greatly appreciate them. Thanks in advance for any guidance. Thanks. I'm in the process of building a blog that will be using some pretty neat jQuery effects to spotlight its content. One thing I've been looking at doing is trying to lessen the amount of different pages the visitor has to load by using things like sliders and accordions to hide and display content. Overall I'm not concerned that the pages will take more than 3-4 seconds on any decent connection to load, however I was thinking about visitors who are potentially running slower connections. To avoid losing those slower-connected users I've been looking for a way to display a page loader, much like what you see on flash websites, except completely without flash. I was hoping there might be some AJAX algorithm or jQuery function I wasn't aware of that might help me accomplish this. If anyone could point me in the direction of a tutorial, I'd really appreciate it! Thanks in advance. I want to update the variables in the progress bar HTML5 has to offer. Here is the function I have so far (It has been modified and shortened for the means of this post): Code: function calcProgress()
{
var num1 = Number(document.form.num1.value);
var num2 = Number(document.form.num2.value);
Number(document.form.progress.value) = num1
Number(document.form.progress.max) = num2;
}
This is the form: Code: <form name="form"> <input name="num1" onChange="calcProgress()" type="text" value="0" /> / <input name="num2" type="text" value="0" onChange="calcProgress()" size="1"> <br> <progress name="progress" id="progress" min="0" value="0" max=""></progress> </form> Hi, I have searched the web for many tools to upload a file and shows it progress, but they all seem to use, flash, codebehindfiles, php etc. I was looking for one that used pure Javascript was wondering if anyone could help? Thanks Marcel. Hello, recently I have been to many government websites where I have noticed that the programmer has used window.open() method in JavaScript to link to different pages instead of using <a> tags! I was just getting curious to know whether it is normal or has it been used due to security concerns(if any, I don't know)? Any comments? Hello, I run a online gaming website, and I'm having problems with certain websites iframing our games. Actually I'm ok with iframing, as long as they include the banner ad located just beneath our games. But often times unscrupulous webmasters will iframe only the game, preventing us from generating any revenue from the banner ad (and costing us additional bandwidth charges). I'm hoping to find a way to detect the dimensions of the iframe, so that I may dynamically resize the game, in order to include the banner ad within the iframe. Does anybody know how to extract the "height" and "width" attribute values from an <iframe> tag sitting on a different site? Regards, Steve Hi all, I'm having a bit of a problem..

if its possible to make it do both in 1 function, please show an example. if you have to use 2 functions, then also show me an example. ANY help is GREATLY appreciated! Hi guys, I have a JS calculator on my website which is basically a load of radio buttons that the user clicks and as they do so a price is calculated in their view. At the moment - the price box starts with a blank box but is essentially "0". Then, as the user select an option, the price appears and then starts to calculate when more than 1 is pressed. All I want to do is have the price start at "300" instead of a blank box or "0". Then the rest of the options calculate onto that. I have tried a variety of ways to achieve it and seem to be missing something! I am pretty new to JS although do have a basic understanding ..... clearly not enough to do this thou! lol Basically imagine 300 is the initial price. That only gets charged once ... Here's my code .... In the <head> Code: <script type="text/javascript">
function getRBtnName(GrpName) {
var sel = document.getElementsByName(GrpName);
var fnd = -1;
var str = '';
for (var i=0; i<sel.length; i++) {
if (sel[i].checked == true) { str = sel[i].value; fnd = i; }
}
return fnd; // return option index of selection
// comment out next line if option index used in line above
// return str;
}
function chkrads(rbGroupName) {
var ExPg = [
[0,''],
[100,"1 extra page"],
[200,"2 extra pages"],
[250,"3 extra pages"],
[300,"4 extra pages"],
[350,"5 extra pages"]
];
var ExEm = [
[0,''],
[10,"1 extra email"],
[20,"2 extra emails"],
[30,"3 extra emails"],
[40,"4 extra emails"],
[50,"5 extra emails"]
];
var ImgBun = [
[0,''],
[10,"3 extra image"],
[20,"5 extra images"],
[30,"7 extra images"],
[40,"10 extra images"]
];
var rbtnGroupNames = ['extrapages','extraemail','imagebundles'];
var totalprice = 0;
var tmp = ''; var items = [];
for (var i=0; i<rbtnGroupNames.length; i++) {
tmp = getRBtnName(rbtnGroupNames[i]);
if (tmp != -1) {
switch (i) {
case 0 : totalprice += ExPg[tmp][0]; if (tmp > 0) { items.push(ExPg[tmp][1]); } break;
case 1 : totalprice += ExEm[tmp][0]; if (tmp > 0) { items.push(ExEm[tmp][1]); } break;
case 2 : totalprice += ImgBun[tmp][0]; if (tmp > 0) { items.push(ImgBun[tmp][1]); } break;
}
}
}
document.getElementById('QUOTED_PRICE').value = totalprice;
document.getElementById('ITEMS_SELECTED').value = items.join('\n');
document.getElementById('PRICE_IN_VIEW').innerHTML = totalprice;
}
function validate() {
// add any required validation code here prior to submitting form
var allOK = true;
// if any errors found, then set 'allOk' to false;
return false;
// after testing with validation code, change line above to: return allOK;
}

Thanks for your help in advance! i am trying to make a comment editor with iframe, and want to trigger the change of content inside iframe, the following code cant work. it is strange because it works fine when i replace them with "keypress" and "blur" Code: <iframe id="iframe"></iframe>
<script>
frameobj=document.getElementById('iframe').contentWindow;
// IE
frameobj.attachEvent('onpropertychange', function(){alert();} );
//FireFox
frameobj.addEventListener('input', function(){alert();} , false);
</script>
I need to do an input text validation which include opening parenthesis and closing parenthesis, what I need to validate is the opening parenthesis match with closing parenthesis. Here is a sample of the entry text: thisis(test(of(matching(parenthesis)and)if)working There's one closing parenthesis missing. I would like to warn the user to correct it before submit, but not quite sure how to do it with javascript. Please advice. Thanks JT |
