JavaScript - Document.getelementbyid(msg) Is Null
Hi....I have an error in my script, but idk where it is..... here is the script:
Code: <script type="text/javascript">
var browser = navigator.appName;
if (browser=="Netscape") {
document.getElementById(msg).style.display="none";
}
</script>
<div id="msg" style="width:100%;padding:3px;position:fixed;top:0px;left:0px;background:red;">Please install <a href="http://www.mozilla.org/sk/firefox/">Mozilla Firefox</a> to view this page normally.</div>
Similar TutorialsHi, first post here. I was working on code for opening a link in a new window when clicked. I read somewhere that it's a good idea to remove all of the javascript elements from the HTML. So I pieced it together and it works. But I get the following error in IE8: Code: Message: 'document.getElementById(...)' is null or not an object Here's the relevant HTML: Code: <a href="http://www.samplesite.com" id="sampleid">Sample Text</a> And here's the relevant javascript that I put in a seperate .js file: Code: function samplefct() {
window.open(this.href);return false;
}
window.onload = function()
{document.getElementById("sampleid").onclick = samplefct;
}
The code does work as planned. But I'd still like to get rid of the error. Can anybody think of a different way of stating the javascript that would perform the same thing and lose the error? Any help would be greatly appreciated. Thanks! IB Hey all, For the below code, I'm just trying to create a simple toggle menu for a Table of Contents. However, when page loads, I get document.gelementbyid('sidebar') is null even though it's clearly there and if I move script to below markup, it will also give me a hideElements() is not a function error, even though it clearly is. Code: <script type="text/javascript">
(function(){
var headers = document.getElementById("sidebar").childNodes;
for(var i=0; i < headers.length; i++){
hideElements(headers[i]);
if(headers[i].nodeName == "h1"){
headers[i].childNodes[0].onclick = function(){
hideElements(headers[i]);
this.parentNode.nextSibling.style.display = "block";
return false;
}
}
}
var hideElements = function(element){
if(element.nodeName == "UL") element.style.display = "none";
}
})();
</script>

Thanks for any response. I'm getting the following problem. The reason is that the object appears through AJAX. But if I choose it NOT to appear it gives this problem. How can I avoid this? I put an if statement inline Code: if(document.getElementById('vsbtitle_1').value!=null){
thisurlext+='&btitle1='+document.getElementById('vsbtitle_1').value;
}
But it doesn't help.

Hello, I'm working on some php and javascript. I have php creating some forms using values from a database and wrapping them in divs called showform1, showform 2 etc I then want to use Javascript to show one form at a time when I click on a tickbox. So I've got it working so when you click on a checkbox and it shows the right form, but I want it to hide all the others first so it only shows one at a time if possible. When I do this is errors saying document.getElementById(showform1) is null - it does this for all the forms not just the first one. My php goes like this: PHP Code: $i=1; //loop through all things in db while ($info_query = mysql_fetch_assoc($info)) { ?> <label>Item <?php echo $i;?></label> <input type="radio" name="show" value="show" onclick="showhide(this.value,'showform<?php echo $i;?>')"/> //here's the div with the dynamically generated ID... <div id="showform<?php echo $i;?>" style="visibility:hidden;height:0px;"> <p> info for item 1 </p> </div> //increment the counter so the next div has a different name $i=$i+1; } My Javascript looks like this: Code: <script type="text/javascript">
function showhide(radval,divid)
{
if(radval=="show")
{
<?php
//hide them all first
$i=1;
while ($details_query = mysql_fetch_assoc($details))
{?>
var showform<?php echo $i;?>;
document.getElementById(showform<?php echo $i;?>).style.visibility="hidden";
document.getElementById(showform<?php echo $i;?>).style.height="0px";
<?php
$i=$i+1;
}
//then show just the one ticked
?>
document.getElementById(divid).style.visibility="visible";
document.getElementById(divid).style.height="auto"
}
}
</script>
the details and info queries are the same query...each looping through the same data. It works if I don't hide all the values first, and shows each form when I tick the box, but if I try to hide them all and THEN make one visible, the first line that hides the divs always errors. I've moved the JS around to the footer, the header in case its because stuff hasn't loaded yet, but it doesn't make sense as it has loaded to work to show the div. Really appreciate your help. Thanks, Nicola I have a button you should be able to click on it once and have one new page open into ID 1 then you should be able to click on it again and have a second page load into ID 2. Sometimes it works sometimes it doesnt. I have no idea why. The script is below. I highlighted the bits I think relevant. When it doesn't work I get the error message: document.getElementById(...)' is null or not an object Mainpage: Code: <?php
session_start();
if (!(isset($_SESSION[login]) && $_SESSION[login] !='')){
header ("Location: Welcome.php");
}
$Sfullname=$_SESSION['fullname'];
$SMyPId=$_SESSION['MyPId'];
?>

So in the js file I have: document.getElementById("resetButton").onclick = doAlert; doAlert is a function that simply does: alert("Do you want to reset?"); I know my separate js file is linked correctly because if I just put in alert("hello"); in the js file then it works. But if I use the document.getElementById thing in the js file, then there is an error. The error, according to the error console, says that "resetButton" is null. Can someone help me? thanks! btw, I'm totally new to programming...and I need to do this for my homework assignment I am writing some javascript that when the user clicks on a link, it hides or displays content inside a div tag. I have been trying to add some code that would only allow for one div tag to be displayed at a time. Here is where I originally got the code (http://www.willmaster.com/library/hi...-to-reveal.php) Whenever I run this code I get this error: Code: Error: document.getElementById(months[x]) is null Source File: /resources/default.js Line: 30 This is the JavaScript that runs when the user clicks the link: Code: <!--
function accordion(tid) {
var x;
var months = new Array();
months[0]="January";
months[1]="February";
months[2]="March";
months[3]="April";
months[4]="May";
months[5]="June";
months[6]="July";
months[7]="August";
months[8]="September";
months[9]="October";
months[10]="November";
months[11]="December";
for (x in months) {
document.getElementById((months[x])).style.display = "none";
}
if(document.getElementById(tid).style.display == "none") {
document.getElementById(tid).style.display = "";
} else {
document.getElementById(tid).style.display = "none";
}}
//-->
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> What I'm trying to get are the tag ids separately after I call the callback function. I've been racking my brain for far too long on this one. Here is a shorter version of what I have. I'm using the array's length to count and break into their own lines. How do i get all 9 id="hover_[index]" separately using my array length? PHP Code: var info = Array("bla_1", "bla_2", "bla_3", "bla_4", "bla_5", "bla_6", "bla_7", "bla_8", "bla_9"); function callback(results, status) { if (status == myStatus) { for (var i = 0; i < results.length; i++) { send(results[i]); } } } function send(info) { document.getElementById('results').innerHTML += "<div id='hover_"+info.length+"'>Something</div>"; hover_target = document.getElementById('hover_'+info.length);// how do i get all 9 hover_[index] separately? someEvent.addDomListener(hover_target, 'mouseover', function() { // do something }); } Thank you so much in advance, Frank Hello everyone. As lame as this may sound, I can't for the life of me get the document by the id. All looks fine to me, but I get the following error that just simply doesn't make sense.

the problem is when i select a link the first time. it works fine. but when i select another link the next time the script does not work. Basically it works only once when page is loaded and then its not working at all. Its not showing any errors either. don't know whats happing.? Can someone please help me its urgent? Any help will be really gratefull! Hello, I have a website that I need help with. You can visit it he http://www.shahspace.com/bow/home.html. To see what I need help with, click on the services menu item and observe the alert message that comes up. It should say "point 1". Here is the code that executes that: Code: function enableScrolling(menuName)
{
alert("point 1");
var menu = document.getElemenetById(menuName);
alert("point 2");
...
}
As you can see, there should be a second alert message that says "point 2", but there isn't. The script is crash when I try to assign to menu the object returned by document.getElementById(menuName). I have verified that menuName is correct. So why would this be crashing? To get a fuller understanding of my algorithm, I'll give you the following: The menu div: Code: <div id="services_menu" class="services_menu"> ... </div> The "services" button: Code: <td><a href="#" onclick="displayMenu('services'); return false;"><img src="services.jpg" border=0></a></td>
The displayMenu() function: Code: function displayMenu(menu)
{
var menuName = menu + "_menu";
document.getElementById(menuName).style.display = "block";
if (itemCount(menuName) >= 12)
{
enableScrolling(menuName);
}
else
{
disableScrolling(menuName);
}
}
The itemCount() function: Code: function itemCount(menuName)
{
var menu = document.getElementById(menuName);
var divArray = menu.getElementsByTagName("div");
return divArray.length;
}
And the enableScrolling() function I already posted above. So essentially, when the user clicks on "service", the services menu becomes visible. If the menu contains 12 items or more, scrolling needs to be enabled. This entails setting the menu to a fixed height and allowing the user to scroll through it (scrolling, in this case, will be customized--I'm not using the div's native scrolling feature). The really odd thing is that in itemCount(), I have exactly the same line: var menu = document.getElementById(menuName); and it works fine there. Why not in my enableScrolling() function? I am trying to pass a value to a function autosuggest() f and i but i get the error... Message: Syntax error Line: 21 Char: 29 Code: 0 ajax_autocomplete2/ajax_search_for_airport_framework.js line 21 being q = ..... how do i correctly pass a value to the function and use it in the function to get the value of an element. Code: function autosuggest(f,i) {
q = document.getElementById(f).value;
....
}
Hello all, I am trying to use document.getElementById in FF but its not working. There is a main page. in that mainpage there is a iframe and in that iframe (id = DocFrame) there is a textbox (id="fileuploadedcnt") which i am trying to access. there is no error. ofcourse i have given name and id to the textbox. Below is the code function ConfirmCertificate(id , Project_ID , Subprogram_ID , ITCType_TI) { frm=document.mainform; //fileuploadedcnt = (document.frames("DocFrame").document.forms("upload_form").elements("fileuploadedcnt").value); filecntobj = (document.getElementsByName("fileuploadedcnt")); filecntobj = (document.getElementById("fileuploadedcnt")); alert(fileuploadedcnt); alert((filecntobj.value)); return; if (fileuploadedcnt>0) { result=confirm("Are you sure you want to confirm this certificate? "); } In the abpve case i tried both the name and id properties. with Name property i get the HTMLObj alert but again it fails if i attach value method. And for id, it doesnt work at all No errors ofcourse in both the cases What am i missing Thanks Hi ALL, I am validating a three form field which takes temperature value between 0-50, humidity 1-100 & rainfall 0-200.

HI.....idk why it is not working......when I load site, it will start counting, but dots after that .lib files.....look: http://ikoos.tk/load_os/ ......if you don't know what I mean....try to send me a PM. Thank you. i have the code in JS: Code: if(drop_list.value == "zed-catcher/11")
{
input_box.disabled=false;
var catcher_id = document.getElementById('lpm_service_catcher_id');
catcher_id.value = 11;
}
else
input_box.disabled=true;
how come the line catcher_id.value = 11; is not setting the value to 11???? i get that catcher_id = null???? pleas help thanks I need help creating something hard. First I need to divs that change by ONE button and when they change they say two different things and must be onclick. The other thing is there will be 4 buttons. They start black and when you click one it turns grey and when you click another it turns gray and the other one that was last clicked turns back black and same with the other two. Hello again, I seem to be having trouble with my string variable in innerHTML.. here's my code: Code: function header() { // Navigation Bar
110 var o = document.getElementById("header");
111 var s = '<h3 style="float:left;">'
112 + ' '
113 + '<a href="http://mattondo.com" class="link">MattOndo.Com</a></h3>'
114 + '<div style="float:right;">'
115 + '<div class="navbar">'
116 + '<a href="index.htm" class="nav" id="home">home</a>' //to homepage
117 + '<a href="about.htm" class="nav" id="about">about</a>' // to about page
118 + '<a href="construction.htm" class="nav" id="blog">blog</a>' // to blog page
119 + '<a href="contact.htm" class="nav" id="contact">contact</a>' // to contact page
120 + '</div>'
121 + '</div>';
122 o.innerHTML = s;
every time I run this using firebug, it says I have one error. That on line 122 variable o is null. And when I go through the code using firebug line by line, it gets to thevar o = document.getElementById("header"); and stores nothing in o, making it null. What could be my issue here?? |
