JavaScript - .getelement Function Returning "undefined"
Here is a clip of code from a script project im working on. Now my document.getElementsByTagName is returning a "undefined" value.
Can anyone tell me whats wrong with my code? Code: <a href="http://www.anotherrandomsite.com" style="text-decoration: none; color: #EDDBAF; font-size: 16px;">
<center style="margin-left: 10px; margin-right: 10px;">
<font style="color: #EDDBAF; font-size: 16px;" id="title"></font>
</center>
</a>
<li id="name"><a http="http://www.randomsite.com" style="color: blue;">John Doe</a></li>
<script type="text/javascript">
var pname = document.getElementById('name').getElementsByTagName('a');
//now if i remove the ".getElementsByTagName('a')" it will actually work,
but it also includes the <a> tag thats within the <li> tag, which i dont want.
document.getElementById('title').innerHTML=pname.innerHTML;
</script>
Similar TutorialsHi, My webpage can work normally in IE but not in Safari(e.g. when I clicked on some buttons like 'Delete' button, the page opened in Safari stays the same while it should delete the object chosen). When I tried debugging on Safari, after clicking the 'update' button, this message error appeared: "TypeError: Result of expression 'this.form.fireEvent' [undefined] is not a function". I believe this code makes the incompatability between the 2 browser: Code: function DeleteClick()
{
var frmSWO = document.getElementById("form");
var answer = confirm("Do you really want to delete?")
if (answer != 0)
{
frmSWO.action = "/domsWeb/mtd/doms/web/operation/eDepotMNR/controller/manageWorkOrder/DeleteJobOrImage.do";
frmSWO.method = "post";
this.form.fireEvent('onsubmit');
frmSWO.submit();
}
}
Any suggest how should I amend the script for it to work on 2 browser concurrently? Thanks all! Hi everyone, I'm using a JavaScript to upload multiple files, namely this one: http://valums.com/ajax-upload/ The script has the ability to post additional parameters to the server, by calling the function setParams Code: var doktyp = "default";
var uploader = new qq.FileUploader({
element: document.getElementById('file-uploader-scope'),
action: 'uploads.php',
// additional data to send, name-value pairs
debug: true,
onSubmit: uploader.setParams ({
dateityp: getCheckedValue(document.forms['doktyp'].elements['dateityp']),
comment: jQuery('#dateityp').val()
})
});
Without the onSubmit: part the script works well and does as it's supposed to, but with it FireBug reports "uploader is undefined" und the script seizes to function. Now JavaScript istn't my strong suit, so I have been reading up on this for the last two hours, tried calling that function from a different place, tried to modify it, but no luck; the error remains the same (or slightly different; if I point at the class in question directly, the function doesnt work...). I would appreciate any advice you could give. Hi, window.clipboardData.getData("text") is giving undefined on remote server(unix). When deployed locally(windows xp) it is coming giving correct value. In both cases the brower is IE running on windows xp. Is there anything wrong in the way I am reading the clipboard data? Alright so this is my problem. I'm using ajax to validate my form without refreshing the page. Everything works but the message part of my contact form. The name, email, and subject get passed but the message returns back as "undefined". I've looked through some of the older posts with the keyword being undefined and I didn't really find anything that helped. I've been trying to get this working for like days now an I'm sure its something really simple and right under my nose. So I will post my html for the form and the validation code. I want to thank all who help. Here is the HTML Code: <div id="forminfo">
<form name="contact" method="post" action="">
<dl>
<dt id="name"><label for="fName" class="">Name</label></dt>
<dd><input type="text" class="text" name="fName" id="fName" style="width:200px; height:20px;" /></dd>
<label class="error" for="fName" id="fName_error">This field is required.</label>
<dt id="eMail"><label for="email" class="">Email</label></dt>
<dd><input type="text" class="text" name="email" id="email" style="width:200px; height:20px;" /></dd>
<label class="error" for="email" id="email_error">This field is required.</label>
<dt id="subject"><label for="subject">Subject</label></dt>
<dd><input type="text" size="8" maxlength="40" name="subject" id="subj" style="width:200px; height:20px;" class="text" /></dd>
<label class="error" for="subject" id="subj_error">This field is required.</label>
<dt id="comments">Message</dt>
<dd><textarea name="memo" class="text2" id="memo"></textarea></dd>
<dd><input type="submit" class="button" id="submit" name="submit" value="" /></dd>
</dl>
</form>
</div><!--forminfo-->
Here is the JavaScript/AJAX Code: $(function() {
$('.error').hide();
$('input.text-input').css({backgroundColor:"#FFFFFF"});
$('input.text-input').focus(function(){
$(this).css({backgroundColor:"#FFFFFF"});
});
$(".button").click(function() {
// validate and process form
// first hide any error messages
$('.error').hide();
var name = $("input#fName").val();
if (name == "") {
$("label#fName_error").show();
$("input#fName").focus();
return false;
}
var email = $("input#email").val();
if (email == "") {
$("label#email_error").show();
$("input#email").focus();
return false;
}
var subject = $("input#subj").val();
if (subject == "") {
$("label#subj_error").show();
$("input#subj").focus();
return false;
}
var comments = $("input#memo").val();
if (comments == "") {
$("input#memo").focus();
return false;
}
var dataString = 'fName='+ name + '&email=' + email + '&subj=' + subject + '&memo=' + comments;
//alert (dataString);return false;
$.ajax({
type: "POST",
url: "bin/process.php",
data: dataString,
success: function() {
$('.formContainer').html("<div id='message'></div>");
$('#message').html("<h2>Contact Form Submitted!</h2>")
.append("<p>I will be in touch soon.</p>")
.hide()
.fadeIn(1500, function() {
$('#message').append("<img id='checkmark' src='images/check.png' />");
});
}
});
return false;
});
});
runOnLoad(function(){
$("input#fName").select().focus();
});
Code: <script type="text/javascript">
function loadText()
{
var t1=setTimeout("document.getElementById('data').innerHTML='<center><img style=\"margin-top:30px;\" src=\"loading.gif\" /></center>'",0000);
var t2=setTimeout("document.getElementById('data').innerHTML='THEPAGE'",6000)
}
</script>
The above is in the header, and I'm calling it in the html. Code: <script type="text/javascript"> document.write(loadText()); </script> in the page it displays properly, but then it also says "undefined" not sure why? anyone have any ideas? I've been testing my site in firefox and safari and everything was a OK. Now IE is telling me that "pagetracker" is undefined and its not taking me to the other links on my site.

And when trying to submit the form, I get the error message: Code: Line: 177
Character: 4
Code: 0
Error Message: 'undefined' is null or not an object
URL: https://localhost/ruff/scripts/validationVol.js
Do you have an idea what could be the problem? As I checked line 177, it seems to be OK. I checked the web, but didn't find anything related to this message in a situation like this. Thanks in advance for your comments. Whenever this function sorts itself out, the value of the variable I want ends up "undefined". It starts here in my code with this link. $sort is the variable that's giving me trouble. If I echo it here, it works correctly. Code: <a id='showMoreLink' onclick='showMorePosts($showMoreCount,$sort)'>Show more...</a> Here is snippets of the showMorePosts function Code: function showMorePosts(str,sortBy)
{
xmlhttp.open('GET','ajaxQueries.php?sort='+sortBy+'&q='+str,true);
xmlhttp.send();
}
And here is where I am echoing $sort in ajaxQueries.php, and getting "undefined". Note that $q works just as it should. (All I can think is q is an integer, and sort is a string) PHP Code: $q=$_GET['q']; $sort=$_GET['sort']; echo $sort.$q; Hello. My goal is to write a form input to the cookie. The rest of the cookie works, and if I declare var user_email = 'muppet';, the content becomes "muppet". However, if I try to do something more dynamic, like var user_email = document.addform.email it becomes "undefined". I tried adding ".value" to that as well. I have been at this since yesterday, and tried solutions like running a setEmail() function, or getElementById. Here is my cookie writing function, which I call with onsubmit="createCookie('userEmail',user_email,365)" Code:
<script type="text/javascript">
var user_email = 'muppet';
function createCookie(name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}
</script>
The form looks like this: Code: <form name="addform" action="http://formmail.dreamhost.com/cgi-bin/formmail.cgi" method="post" onsubmit="createCookie('userEmail',user_email,365)">
<input type="hidden" name="required" value="email" />
<input type="hidden" name="redirect" value="http://www.saverally.com/confirmed.html" />
<input type="hidden" name="recipient" value="addme@saverally.com" />
<input type="hidden" name="subject" value="add to list" />
Your Email: <input type="text" name="email" name=email size="20" value="" />
<input type="submit" value="Send"/>
</form>
Thanks! 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! I had some code written for me. Basically it outputs something like this based on user input: Code: <span>name 1 - <a href=\"test1b\" rel="nofollow" target=\"_blank\">test1a</a> - $12</span><br/> <span>name 2- <a href=\"test2b\" rel="nofollow" target=\"_blank\">test2a</a> - $24</span><br/> What it used to look like: Code: /**

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.. I need to disable the submit button on body onload, and i need to re-enable it when "i agree" is checked. the problem is, it wont do this.. it literally stays disabled, even after check mark.. code: Code: <html>

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! 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? ok so Code: document.write("Goodbye!");
works but I put ^ that inside a function Code: function SayHello ()
(
document.write("Goodbye!");
)
and it stops working? I know the function call works because when I place some code to display an image in SayHello function, it displays the image. Quote: <html> <head> <script type="text/javascript"> var a = january var b = febuary var c = march function test() { document.getElementById("test").innerHTML=a; <!-- needs to be A on first function click, b on second, c on third, etc..^^--> } </script> </head> <body> <p id="test"></p> <!-- the <p> should go to next month upon each function --> <input type="button" value="asdf" onclick="test()" /> </body> </html> I tried to explain it pretty well in the comment tags, thanks! I'm trying to get the following function working Code: function jump(document_root, mode, cat, id, qs)
{
var response = confirm("Are you sure that you want to completely delete this record");
if(response)
{
var url = document_root+"/"+mode+"/"+cat+"/"+id+qs;
window.location(url);
return true;
}
else
return false;
}
It called with the following Code: <a href="" onclick="jump('/tradedoubler_admin/web', 'Pages', 'Delete', '011' ,'');">Delete</a>
But the redirect isnt working i get the following error : Code: Error: uncaught exception: [Exception... "Cannot convert WrappedNative to function" nsresult: "0x8057000d (NS_ERROR_XPC_CANT_CONVERT_WN_TO_FUN)" location: "JS frame :: http://192.168.1.99/tradedoubler_admin/web/scripts/pagejump.js :: jump :: line 7" data: no] Is any one familiar with this error? It's suppose to be a pop up box that asks if the user really want to delete this record, if he clicks yes it redirects to delete it, but if not it doesn't do anything. Hello im having trouble with my onclick button specifically the "doall" is there a problem with my function or the button? Console says ReferenceError: doAll is not defined but I have set the function doAll so I don't get what's wrong. <!DOCTYPE html> <HTML> <HEAD><TITLE>Choice</TITLE> <meta content="text/html;charset=utf-8" http-equiv="Content-Type"> <meta content="utf-8" http-equiv="encoding"> <SCRIPT Language="javascript"> muresources="" muresources["classical"]= "<A HREF='http://net.com/classical.file1'>Meditative classical music<A><P> <A HREF='http://net.com/classical.file2'>Provoking classical music<A>" muresources["rock"] = "<A HREF='http://net.com/rock.file1'>Popular rock music<A><P> <A HREF='http://net.com/rock.file2'>Exciting rock music<A>" muresources["ethnic"] = "<A HREF='http://net.com/mexican.file1'>Mexican music<A><P> <A HREF='http://net.com/Indian.file2'>Indian music<A>" function getLink() { temp = muresources[choice] temp2 = "<TITLE>Custom Links</TITLE><H3>" +document.m.pername.value+", here are some links for you</H3><P>"+temp } function writeIt(){ diswin = window.open(); diswin.document.open(); diswin.document.write(temp2); diswin.document.close() } function doAll(){ getLink(); writeIt() } </SCRIPT> </HEAD> <BODY > <H3> Choose the kind of music you prefer<BR> and this page will fetch links of interest to you</H3> <HR> <FORM NAME="m" > Choose a kind of music<P> <INPUT TYPE="radio" NAME="mus" VALUE="classical" OnClick="choice='classical'" >Classical <BR> <INPUT TYPE="radio" NAME="mus" VALUE="rock" OnClick="choice='rock'">Rock<BR> <INPUT TYPE="radio" NAME="mus" VALUE="ethnic" OnClick="choice='ethnic'">Ethnic<BR> <HR> Please type your name<P> <INPUT TYPE="text" NAME="pername" SIZE=25> <HR> <INPUT TYPE="button" NAME="sub" VALUE="Show me links" OnClick=doAll()> <INPUT TYPE="reset" NAME="res" > </FORM> <SCRIPT> choice = "classical" document.m.mus[0].checked = true document.m.mus[1].checked = false document.m.mus[2].checked = false </SCRIPT> </BODY> </HTML> Title basically says it.

Apart from any logical mistakes this thing i have created might have , my question is this.Why upon pressing the last button and calling the "scor(j)" function , no alerts pop up?Thanks in advance. I'm completely stumbled by this as i have no clue as what might be wrong.But then again , my experience is extremely limited |
