Document.formname.elementname.value Not Working In Loop?
Jun 6, 2011
I'm not so good at Javascript, but I tried to write some code to obtain some form values and write those to a query string to use in AJAX.It seems to be working partially, but I don't understand what is going wrong. What happens is that in the for loop the 'document .form_name.form_field_names_array[i].value' part doesn't seem to return a value. It is worse even: the script completely stops executing at that part. When I remove that part from the line in the for loop, it doesn't stop executing, so I guess that's where the problem is?
function doAjaxForm(url, target_element_id, img_url, form_name, form_field_names)
{
// Create the GET query string from the form_fields[code]...
// Rest of the code (the AJAX) is working.

I thought I once saw somewhere that a global variable, "xyz" for example, could be declared and used so that instead of using "document.formname.elementname.value" one could use "xyz.elementname.value" or use "xyz" in place of "document.formname" anytime a reference to a form element was made.
Is this actually true or not? I'm going crazy trying to recall something that might not even exist!

I am developing in firefox 1.0+, but will be working in an msie 6.0+
produciton environment ( not my choice, but when is it ever? ).
the desired output is that when the end-user selects two radio buttons,
one from each 'group', the form / page will open an alert window
displaying the values of the radio buttons selected without having the
end-user left-click on a submit button.
i cannot figure out why I'm getting the "document.[formName] has no
properties" error mesasage in the javascript console....

I've been looking around the web and forums for the past few days now. Javascript is not my forte but I am beginning to understand more of it. My issue is perhaps in the method that I have tried to concatenate a variable to my radio buttons.
The scenario:I have about 10 groups of radio buttons , each with 4 options.
radioname1[0]
radioname1[1]
radioname1[2]
radioname1[3]
[code].....
but what I need to know is how to assign a variable to the radioname, so that I can iterate through each radionameVARIABLEHERE[i].value ?
I have been looking and trying to for days. All I really need to know is how to get a variable into the radiobutton name. I know how to use a for loop to get this to iterate through it all but its just the syntax that isn't playing nice.

I can successfully force submission of a <form> using "document.formname.submit()". But, the submission doesn't appear to occur when used with Netscape. Anybody know why this is happening, and what I can do to get around this?

I want to have my images load first, then have four different texts fade in onto the layer one after another and all four at different positions on the screen. The code below works if i but in only one x-y position from the x and y array, but the loop to create four different text containers doesn't. Also it's not good form to have javascript in the body like this, right? Any suggestions? Code:

I have the following code and on it's own works fine, but I need to have it in a PHP while loop as there may be hundreds of records. This does not work, meaning it does not submit the form.

I have while loop, where something is defined via ID, I called it pin_click.
So of course there are a few entries.
And I have the following Code:
Somehow, this Code only works for the first element, I get out of the while loop. The other elements of the while loop ( which have the same Button ) are just doing nothing, even no action in Firebug.

I have a form on my page that gets checked and verified with a bit of AJAX and then gets sent off if all is good, but I also created a quick little loop to verify that all the fields are still full and completed before sending the info off to the server officially .here is my test page for the loop that i have created.
PHP Code:
<html>
<head>
<script type="text/javascript">
[code]...
Now the loop works great if you test it by clicking on the button once but if you fill in a missing field and click the button ok then it doesnt work again ... how can i get it to work on every click ?

I'm trying my first bit of jQuery code but am familiar with Java programming. I'm trying to create a function that loads a div with an image in it, which will fade in and then after 4 seconds move onto the next image. I want it to create an infinite loop but it doesn't work.
<script type="text/javascript">
$(document).ready(function ()
{

i have this code
<script type="text/javascript">
$(document).ready(function() {
for ($i=0; $i<4; $i++) {
var num = $('.clonedInput').length;
[Code].....
the input id is changed correctly, but valores no. Why ?? Valores is always id="valores1", and must be id="valores1", id="valores2", and so on.

I have a javascript that is supposed to read a text file (a log from a php script) and it should be shown in a html page. Even more, it should read that txt file again every 10 seconds and update the result every time on the page.
I use xmlhttp for this, after a suggestion from someone on this forum. My script is working well, but only the first time the page is loaded. From then on it becomes unrelieable and I dont know why.
This is the first part: loading a function in the body tag, and a browser version check, I dont think there is any problem in this.
Code:
<body onLoad="showbuffer();">
<script language="JavaScript">
<!--
var xmlhttp=false;
/*@cc_on @*/
/*@if (@_jscript_version >= 5)
try {
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
} catch (E) {
xmlhttp = false;
}
}
@end @*/
if (!xmlhttp && typeof XMLHttpRequest!='undefined') {
xmlhttp = new XMLHttpRequest();
}
//-->
</script>
This is the second part, a self made looping function that looks up buffer.txt , and writes it on the page.
Code:
<script language="JavaScript">
<!--
function showbuffer() {
xmlhttp.open("GET", "buffer.txt",true);
xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState==4) {
buffertext=xmlhttp.responseText;
document.body.innerHTML= buffertext;
}
}
xmlhttp.send(null)
return false;
setTimeout('showbuffer()', 10000);
}
//-->
</script>
And this works, if I load my page then it shows exactly the content of buffer.txt . And if a bit later some data is added to the txt file, then it doesnt show up in the xmlhttp page , its still the same content as from the beginning so it didnt update. But there is something really weird about it, if I open up a second browser window and typ in the complete url of the buffer.txt file, and visit that page and look at the new data... then within 10 seconds the new part is added to the xmlhttp page. So the javascript function doesnt work, unless I refresh the page it is supposed to read. I've tried to mimic that, with a php script in crontab that would read buffer.txt through file(); or fopen(); every minute , but that didnt seem to work.
I dont think there is anything wrong with all the xmlhttp part of it, but rather with the way I try to integrate it into a loop. But this setup with setTimeout is the only way I know to make a function repeat itself with a few seconds delay after every step.
So, could anyone please point out how this could be solved ? Maybe another way to loop the xmlhttp part perhaps?

I have a pretty simple function set up to pull XML data into my page, but there's a couple things wrong with it. I'm REALLY new to J Script and really trying my best to learn, but for some reason I'm not yet adept at googling the right results :rolleyes:At the very bottom you can see the data from the first XML entry, so it seems the function itself is working fine, but it's not looping coorectly to access all the data.Also, I want to pull it into the "shows" div of the page, but can't figure out how to put it there (seriously, I am very new with JS). The code below is not working, but the live site has it added to the body, which does show the one entry.Here's the XML function, the XML data and the HTML markup:
Shows function -
function loaddates()
{
var xmlData = document.getElementById("tourdates");
var newDates = xmlData.getElementsByTagName("dates");

I have a simple HTML page with one DIV element with the id "rotator". Inside that, JavaScript is supposed to create boxes that react to mouseovers.
The weird thing is: The whole script works, but ONLY on the LAST box I create, no matter what I do. I can manually add the mouseover code to any one of these boxes, but it will only take on the last one. I can have JavaScript tell me the mouseover status of each box, and they all tell me they have code assigned correctly - but again only the last one works...
Here's the relevant code (yes, highly abbreviated, but it's the part that fails on me):
var maxBoxes = 10;
function initSite() {
var rotator = document.getElementById("rotator");
rotator.innerHTML = "";
[Code]....
initSite is called in the body onload. All kinds of other animation parts are implemented that work fine, just this mouseover won't work. I have tried re-writing it in multiple different ways, including "xyz.onmouseover = myMouseCode" and then defining the function separately later - still no dice.
So, the code creates 10 boxes (0-9) and 10 boxes that are on top of them to create a form of shadow effect depending on the position of the original boxes. Since the "myDark" boxes are on top of the "myBox" boxes, I apply the onmouseover onto the "myDark" boxes, but it only works on "myDark9" and no other box. They are all created the same way, the mouseover assigned the same way...

Here's the code:
for (var i = 1; i < 5; i++)
var pl = eval("player" + i)
var namepl = eval("document.charInput.name" + i + ".value");
[code]....
In the case of the 2nd-4th player, it changes to name2.value, etc.Based on these three inputs, I need to iterate through all four players and make the player object for each of them, as I've done above.

I cant get collision detection to work. I tried but it always caused an infinite loop.
Heres the code.
<html><!-- main file.--><head>
<title>lightning generator</title>
</head><body>
<canvas id='world' width='500' height='500' style='border: 1px solid black; padding:0;'>
</canvas><script type="text/javascript" src='world.js'></script>
[Code] .....
In the end of world.bolt.cpath,there should be a way to use the local varis X and Y, and world.ground.js's world.ground.level[] to detect it. sorry for the gigantic length.

Does anyone know why this isn't working? The toggle function works perfectly fine with PHP loops, but when I insert the table td tr tags, it does not hide the loop when the page first loads...It just shows the results in the div which it shouldn't be doing.
Here's what my code looks like...

Code:
<script type="text/javascript">
function toggle(element) {
if (document.getElementById(element).style.display == "none") {

I have been trying to get the code below working for 9 hours now. Finally, I decided to test the same code on another sever, and it works fine! I have no idea why the same code would work on one server, but not another.
The code is self-explanatory, I created a button that when clicked will navigate the user to a link (#hit1).
Code:
<script type="text/javascript" language="javascript">
function firstHit(){
document.location="#hit1";
