JavaScript - Getelementbyid() Issue (i Think)
I'm working on a web site: http://84.9.221.75/domains/backingtr...usicindex.html
I'm trying to get the Javascript that controls the scrolling text to scroll on both the left and right sides.....right now it only scrolls on the left, due to the use of getElementById() from what i can see.... So I'm trying to make the javascript see all references to the ID in the document, and make the right panel div scroll as well, but I'm not having any luck.... I have a very basic understanding of Javascript, so I need a little help here guys...thanks.. Similar TutorialsHey All, I've got the following few lines of code that set some radio button values within a table: Code: document.getElementById('Price' + lineNumber).value = price;
document.getElementById('Term' + lineNumber).value=term;
document.getElementById('Type' + lineNumber).value=Type;
I also have a table with id="example" that these input fields sit within. In Firefox, this works without an issue, but in IE, I get a 'document.getElementById(...) is null or not an object' error. How can I fix the above code to work with a table ID? I need to keep the table ID present for some other JS code that works off of it. Any help would be greatly appreciated. Thanks. hi, In my code below, I cannot get the setting_id value as it falls outside of the loop. I have just tried to put in the getElementById function but it's not working?! I get the error: missing ) after formal parameters JavaScript from this: Code: function confirmqualification(ID) {
to this: Code: function confirmqualification(document.getElementById('setting_id')) {
HTML from this: Code: <input type="button" name="remove" id="remove" value="Remove" onClick="javascript:confirmqualification('<?php echo $row1['setting_id']?>')" />
to this: Code: <input type="button" name="remove" id="remove" value="Remove" onClick="javascript:confirmqualification()" /> Hello smart people... perhaps someone can figure this one out. I hope it's not a PHP question. I have a form and need to populate FIELD2 with the result of FIELD1. Field one is a dynamic list from a database, where the value is an ID#, but the list shows the name. I want to populat FIELD2 with the name that is chosen, not the id (I can't get anything to work) Here is the code from the 2 fields: FIELD 1: Code: <select name = "" realname = "{#role#}" required="1" exclude = "-1" id = "roleselect">
<option value="-1" selected="selected">Choose</option>
<option value = "{$roles[role].ID}" id="role{$roles[role].ID}">{$roles[role].name}</option>
FIELD 2: Code: <input type="hidden" name="rolename" id="rolename" required="0" realname="rolename" /> Here is the javascript I tried to populate field 2 with the selected option of field 2: Code: function updaterole(){
document.getElementById("rolename").value =document.getElementById("role").value;
I tried using name instead of value for field 1, but that didn't work either. The db just shows empty. thanks for any help! hi quick question, i have 640 hidden html inputs like this but with different names. <input type="hidden" name="b1r1c1" value"some value"> now i want to use document.getElementById('b1r1c1).value = "whatever"; will that work eventhough there is no id on my hidden value. it will be in a hta by the way. thanks Hopefully some of you guys can help. I'm self taught in Javascript so only know little bits here and there (and don't even know if the thread title is labelled right for what I'm doing!) so help would be greatly appreciated. I'm trying to create 4 buttons on a page (buttons shown by "click here to view c1, c2" etc.) however after I've clicked one button and the content is showing below, the content from the next button clicked does not show (almost as if it is hidden underneath). I'm looking for a way of showing the content when the button is clicked, but hiding it once another button is clicked so other content is shown. Hopefully this is clear enough. All help, tips or advice will be appreciated. Thankyou. Code: <script type="text/javascript" language="JavaScript"><!--
function InsertContent(tid) {
if(document.getElementById(tid).style.display == "none") {
document.getElementById(tid).style.display = "";
}
else {
document.getElementById(tid).style.display = "none";
}
}
//--></script>
<table width="100%" cellspacing="4" cellpadding="4" border="0" align="center">
<tbody>
<tr>
<td width="25%"><a href="javascript:InsertContent('c1');"> Click to see C1</a></td>
<td width="25%"><a href="javascript:InsertContent('c2');"> Click to see C2</a></td>

Hello, I need to do this. I have 36 Divs called "contenido1, contenido2, contenido3 etc.) And I want that "onclick" change a property of the css of all of them except 1. I know I can do this manually but its a lot of code lines so I think it would be another option to do ir in a loop. Right now i am using this: Code: div = document.getElementById('contenido1');
div.style.display='block';
div = document.getElementById('contenido2');
div.style.display='none';
div = document.getElementById('contenido3');
div.style.display='none';
div = document.getElementById('contenido4');
div.style.display='none';
....
So in that case I want for example that all the DIVS called "contenido 2 to contenido 36" display: none and only contenido 1 display block. In the next cases would be the same: All the divs called "contenido 1 to contenido 36" display: none except "contenido 2" that i want to display: block. So I can do it like this but are thousands of lines of code... and I am sure there are other more efficient option. Anybody knows how to do that? Probably is a simple question. Thank you!! I've spent three days trying to figure this out without any luck. What i am attemping to do is to open an unframed tab using the link from a frame id. I want to be able to enter a js command in the browser on the page then have it open in a new tab unframed or just reload the link unframed. These are the commands i have tried in my browser: javascript:<a herf="document.getElementById("netlinkx").childNodes[1].src;"> javascript:<a herf="window.location.href=document.getElementById("netlinkx").childNodes[1].src;"> javascript:<a herf=document.getElementById("netlinkx").children[0]>.setAttribute('id','this_one');alert(getFrame("this_one").body.innerHTML);> and a few others that didn't work. I have this code: Code: var player = 100;
var part1 = ('ctl00_cphRoblox_TabbedInfo_GamesTab_RunningGamesList_RunningGamesListView_ctrl0_ctl00_PlayersRepeater_ct');
var part2 = ('_PlayerImage1');
var final = part1 + player + part2;
var name = document.getElementById(final)
The variable (name) turns up null when I try to see what it is. But, it is, infact, an element on the page, and when I do it manually it works. Help? Hi. I'm making a web site...And the following bit of code doesn't work...It sais "document.getElementById(...) is null or not an object"...I tried various combinations of getElementById and getElementsByName but nothing works...Any help is very much appreciated.

Pasul III: Imagini<br/>
Pentru a trimite imaginile care vor aparea pe site (daca exista), aveti 2 optiuni: sa ne trimiteti un fisier .zip, .rar, etc sau sa scrieti un link unde le vom putea gasi.<br/><br/>
Le puteti organiza cum doriti dumneavostra, dar este preferabil sa folositi una dintre variantele urmatoa <br/><br/>
(folder) pagina 1: (folder) pagina 1-1: imaginile care apar pe pagina 1-1<br/>
<table style="color=#FDB91A"><tr><td width="155"></td><td width="250">imaginile care apar pe pagina 1 etc</td></tr></table><br/><br/>
(folder) pagina 1: imaginile care apar pe pagina 1<br/>
(folder) pagina 1-1: imaginile care apar pe pagina 1-1 etc<br/><br/>
(folder - nu este necesar) site: toate imaginile care apar pe site<br/>
<table style="color=#FDB91A"><tr><td width="200"></td><td width="250">fisier text (.txt, .doc, .docx etc) cu numele imaginilor si pagina pe care apar</td></tr></table><br/><br/>
La toate exemplele, in loc de pagina 1 etc puteti scrie numele paginii.<br/>
Puteti adauga pana la 10 fisiere si pana la 15 link-uri. Pentru a adauga inca un fisier/link apasati pe butonul corespunzator.<br/>
Va rugam ca fisierele trimise sa fie de maximum 5 MB. (Puteti downloada si instala gratuit <a href="http://www.rarlab.com/download.htm" target="_blank">WinRar</a> si sa-l folositi pentru a face o arhiva impartita in mai multe bucati.)<br/><br/>

I am trying to alter Playa to use input type images instead of buttons. Part of this involves the need for a rollover image eg. a play button highlights when the cursor is over it. This is the code I have: Code: if (Playa.btnState == "Stop") {
document.getElementById("btnPlayStop").onmouseover = "this.src='images/stophover.gif'"
document.getElementById("btnPlayStop").onmouseout = "this.src='images/stop.gif'";
}
else {
document.getElementById("btnPlayStop").onmouseover = "this.src='images/playhover.gif'";
document.getElementById("btnPlayStop").onmouseout = "this.src='images/play.gif'";
}
<input type="image" src="images/stop.gif" onmouseover="this.src='images/stophover.gif'" onmouseout="this.src='images/stop.gif'" alt="Stop" id="btnPlayStop" onclick="Playa.doPlayStop();" />
Playa.btnState is the alt tag to say whether the state is stopped or started. I have the code working to alternate between "Play" and "Stop" images when the button is clicked, but the rollover doesn't happen. Any ideas? Thanks None of my getElementById (or other) references produce anything but "undefined." This occurs in the latest versions of Fx, IE, Chrome, and Safari, so it must be something I am doing but not not seeing here. I have boiled it down to the following without success, and wonder whether there is some add on interaction. Fx 3.6.12 has the problem with this code: <code> <html> <head> <title>This is a test of getElementById</title> </head> <body> <div id="area" name="area_name">xxx</div> <script type="text/javascript"> var divs = document.getElementsByTagName('div'); var msg = ''; msg = 'Divs[0] contains ' + divs[0] + ' with width = ' + divs[0].width + "\n"; msg +='Test area width by id = ' + document.getElementById('area').width + "\n"; msg +='Test area width by name = ' + document.getElementsByName('area_name').width; alert(msg); </script> </body> </html> </code> Hey guys, Thanks for taking the time to read my post. I am not new to programming or scripting, but I am completely new to javascript and web-based code. Hopefully you guys could help me understand what is going on and maybe help me figure out what I am trying to do. What I am trying to do: -There is an element that has a value <td class="flashField" onmouseover="clearAnswer()"> <div id="flashAnswer" onmouseover="clearAnswer()">answer string here</div> </td> -There is a text box that needs to have the answer above given to it <td class="flashField"> <input type="text" tabindex="1" onkeypress="clearAnswer()" name="q" maxlength="256" size="50"> </td> -There is a next button that needs to be executed <td align="right"> <input type="image" tabindex="2" alt="Next" src="http://website.com/images/next.gif"> </td> So what I am trying to do is create a script through Greasemonkey that will automatically do these things. I am starting small and trying to just get the value of flashAnswer to appear as an alert on the screen by using this code: var answer = document.getElementById('flashAnswer'); alert(answer); But the problem is it posts some weird value ([object XrayWrapper [object HTMLDivElement]]) that most definitely is not "answer string here" and is a bit above me at this point. Any ideas? Any help would be great guys! Thanks! -ellosiph I am writing some javascript that when the user clicks on a link, it hides or displays content inside a div tag.

Here is where the javascript is activated from PHP Code: <a href=javascript:accordion('$month2');>$month2</a><br /> <div id='$month2' style='display: none';> Hello $month2 </div> I have a form that is used to insert a new classified ad or to update an existing ad. When the submit button is pressed a javascript function is called to validate the fields. Some of the fields are set as required. If the field is empty ( as form[i].value = '' ) then this sets an error flag and after all fields have been tested will display an alert and each field that has an error will be highlighted in red. This works great when a new ad is being created, but when the ad is being updated, and a required field is erased then it doesn't popup as an error, as if the script is just ignoring it. Here is the code snipit: Code: function submitbutton(mfrm) {
var me = mfrm.elements;
var r = new RegExp("[\<|\>|\"|\'|\%|\;|\(|\)|\&|\+|\-]", "i");
var r_num = new RegExp("[^0-9\.,]", "i");
var r_email = new RegExp("^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]{2,}[.][a-zA-Z]{2,3}$" ,"i");
var errorMSG = '';
var iserror=0;
// set notification background color
var warnColor = '#<?php echo $this->error_color; ?>';
// loop through all input elements in form
for (var i=0; i < me.length; i++) {
// check if element is mandatory; here mosReq="1"
if ((me[i].getAttribute('mosReq') == 1)&&(me[i].style.visibility != 'hidden')) {
if (me[i].type == 'radio' || me[i].type == 'checkbox') {
var rOptions = me[me[i].getAttribute('name')];
var rChecked = 0;
if(rOptions.length > 1) {
for (var r=0; r < rOptions.length; r++) {
if (rOptions[r].checked) {
rChecked=1;
}
}
} else {
if (me[i].checked) {
rChecked=1;
}
}
if(rChecked==0) {
errorMSG += me[i].getAttribute('mosLabel').replace(' ',' ') + ' : <?php echo html_entity_decode(addslashes(JText::_('COM_CLASSIFIEDSREDUX_REGWARN_ERROR')),ENT_QUOTES); ?>\n';
// notify user by changing background color, in this case to red
me[i].style.background = warnColor;
iserror=1;
}
}
if ((me[i].value == '') || (me[i].value.length < 2)) {
errorMSG += me[i].getAttribute('mosLabel').replace(' ',' ') + ' : <?php echo html_entity_decode(addslashes(JText::_('COM_CLASSIFIEDSREDUX_REGWARN_ERROR')),ENT_QUOTES); ?>\n';
me[i].style.background = warnColor;

Hello, I am retrieving xml - that works well. It is when I use "getElementByID" that things go weird. I can scoop up the elements, but it gives me 4 copies of each. When I try to run thru the first one, it doesn't recognize it as an array. hmm. In otherwords.. lets say I do this. var test = somevars.getElementByID('shoes'); test then looks like this: [shoes shoes shoes shoes] If I click on each "object" (shoes) - then I get the FULL xml in each... so I figure, ok - I'll just grab the first and reiterate thru that. ie.. for y=1 etc.. test[0].length but that doesn't work. Do I have to then reach into the childNodes of this and grab the "shoes" elements? Not sure if I am explaining this correctly. this is what I have: Code:
function fireAjax(){
new Ajax.Request( flashconfig.genXML, {
method: 'get',
contentType: "application/xml",
onSuccess: function( transport ) {
var shoeTags = transport.responseXML.getElementsByTagName( 'shoes' );
var spotlightView = $H();
for( var b = 0; b < shoeTags.length; b++ ) {
$w('title description link linkName image').each( function(cs){
spotlightView[cs] = getNodeValue(shoeTags[b],cs);
});
builddisplay(displayModule, spotlightView);
}
so shoeTags does get an array, but each element/object actually has ALL the shoe items in it - but then repeats... for the other array positions. I tried just grabbing the ".first" or [0] like so, but that didn't work. var shoeTags = transport.responseXML.getElementsByTagName( 'shoes' ).first; or var shoeTags = transport.responseXML.getElementsByTagName( 'shoes' )[0] hi, on my site he http://www.mypubspace.com/default.php I am requesting the rsCounty by Ajax, I am then trying to do the same to the page number value using getElementByID, and building up the querystring, but it's not working properly, on my countypubs.php page which is what I an requesting to get the counties I have added the function again to try and get the PAGE Code: <script language="javascript" type="text/javascript">
function countyFunction(){
var countyRequest; // The variable that makes Ajax possible!
try{
// Opera 8.0+, Firefox, Safari
countyRequest = new XMLHttpRequest();
} catch (e){
// Internet Explorer Browsers
try{
countyRequest = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try{
countyRequest = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e){
// Something went wrong
alert("Your browser broke!");
return false;
}
}
}
// Create a function that will receive data sent from the server
countyRequest.onreadystatechange = function(){
if(countyRequest.readyState == 4){
var ajaxDisplay = document.getElementById('ajaxDiv');
ajaxDisplay.innerHTML = countyRequest.responseText;
}
}
var name = document.getElementById('name').value;
//var rsCounty = document.getElementById('rsCounty').value;
var page = document.getElementById('page').value;
var queryString = "?name=" + name + "&rsCounty=" + rsCounty + "&page=" + page;
//Add the following line
countyRequest.open("GET", "http://www.mypubspace.com/countypubs.php" + queryString, true);
countyRequest.send(null);
}

Why? And how do I correct? Hello, I'm sorry if this has been asked before but I've been googling and looking in reference books for the last couple of days and just haven't been able to find an answer. I'm new to javascript and have just completed my first fully working script to crossfade images and have clickable links to go to a specific image, the code works perfectly when the code is inside of the html document with the elements but when you remove the javascript and put it in a seperate file its unable to get the value of the elements from the html. Is there a way to do this, give the document a alternative src to look in for the elements or something? An example below. Javascript snipit [CODE] imageId = "mainImage"; image = window.document.getElementById(imageId); alert(image); [CODE] image returns null. what I want it to return is the value fro the HTMl document that this file is included in. [CODE] <script type="text/javascript" src="fadeFunctions.js"> </script> </head> <body> <div id="imgHolder" style="position: absolute; top: 200px;"> <div id="topImage" style="position: absolute; top: 0px; left: 0px; z-index: 100;"><img id="mainImg" src="1.png" /></div> [CODE] Thanks for any help or suggestions that you can give. |
