Can someone tell me how to do this if it is possible?
I have a table based web site, and I would like to dynamically change the
text that is shown in a particular cell of a table. I give the cell the
unique ID label1 so I can get a hold of it, and I can get a javascript to
display the data in an alert box (this is just to see if I can access the
text) with:
mycel = document.getElementById('label1');
myceltext = mycel.childNodes.item(0);
currenttext = myceltext.data;
alert(currenttext);
But how do I exchange the text in this cell for something else?
I'm trying to change the text on my page dynamically using getElementById etc. Just not quite sure how to do it.
<script>
function changeIt() {
document.getElementById('change').innerHTML = '*i want the stuff below here (from 'var' to 'text')*';
}
var Result= ((correct / 5) * 100) + '%';
document.write('<p>Result<b>' + score + '</b></p>');

Just need to know how to put the variables and stuff in the 'innerhtml' part?
I'm trying to write a Javascript quiz. The idea being that each question has 4 possible answers. The answers being in the form of multiple choice radio button. Instead of having either a long list of radio buttons and questions or loads of pages with tons of duplicated code, I'd like to make the quiz as one page. Pulling the questions, and possible answers from an array. All this I can do, except for changing the text on the radio buttons. In the past I've used.. getElementById with regular text to good effect, but can't manage it with the radio button. Here is part of my test code..
[Code]...
At this point I have been able to add the row. But what I want to do and am having trouble with is alternating the row colour to the dynamically added row element.
Sample of code I am using:
Code:
var tbody = document.getElementById('tableItems');
var row = document.createElement("tr");
var remainder = tbody.rows.length % 2;
if(remainder) {
row.setAttribute("class", "rowLightGreen");
}
var td1 = document.createElement("td");
td1.appendChild(document.createTextNode(qty));
td1.setAttribute("class","qty");
row.appendChild(td1);
tbody.appendChild(row);
One thing that puzzles me, is that even after adding a row the table my table.rows.length still = 0.
Does anyone know how I can determine the appropriate amount of rows so that I can apply the appropriate class?
Or is there just something blatantly wrong in my approach?
I just picked up JQuery yesterday and I am trying to access the text of a dynamically created text box.[code]The problem is in the btnSave.click function the message always says that the .val() is undefined even when there is text in the textbox.
View 1 Replies View Relatedhow to change the content of a div while text is being entered into an input box.
View 1 Replies View Relatedso i have two functions, expand and colllapse. i want the buttons to start on collapse, and when pushed, change to expand. for instance:
<img id=img1 src=minus.png
so now in the collapse function, i want something like:
var imgID;
imgID = document.getElementById("img"+what);
imgID.src = "plus.png";
imgID.
changing the src works, but changing the onClick does not.
I've found some ways to change the onClick to a function Code:
I have a bunch of input rows, each with id in the form of something like.. item:characteristics:age or item:setting:type1:blah. It's kind of like going down folders to get to the item I want. So as you can see in the code, I am splitting each id and trying to rebuild it in the form item[characteristics][age] then set it to the value of the input field. This is modifying the properties of the item. We already have the item object passed into my code and i'm simply modifying the properties to the new values from the user's input.
Does anyone know how I can do this without eval? I'm mainly using it because the variable name can't be hard coded, it is dynamic.
Here's the code I have so far.

am at the very beginning of Javascript. This is the first website I tried to include Javascript, so don't be too mean
What I want to do is to change a CSS property dynamically. It'll be best if I show you what I did:
<script language="javascript">
function ChangeHeight()
{
var browser = navigator.appName;
[Code].....
Why I want do change this? Well... Different people have different resolutions and I want that my website fits perfectly into the browser.
alert(document.getElementById('content').style.height); This shows just an empty MessageBox with nothing in it.
Something I would like to do is change the value of a label. Let's say I have a textbox and onchange, I want to change the value of that label (say adding numbers together or string concatenation).
This works fine if I use another textbox instead of a label, but I want to show Text rather than an input type. Is this possible? I avoid JS at all costs b/c I tend to suck with client-side programming.
i want to change an images opacity dynamically in mozilla.
im doing it when clicking a button. yhe code used is as follows.
document.getElementById('id').style.-moz-opacity =.5;
but it is not working. i know the problem is with
style.-moz-opacity
assignment. can anyone tell me a best solution.
still beating my head for a popup window anyway I can get it. With JavaScript I can change the content within tag "bodies" but is it possible to change the actual tag itself.
Code:
<form id="loginForm" name="login" action="" method="post" onSubmit="timerWindow($username)">
<input type="text" name="username" value="" onBlur="doUsername();">
I'm using onBlur on the username field so as soon as the event happens I can do the JavaScript call. What I want to do is have the username (that was just entered) passed to the timerWindow function. I think it is getting close to being solved.
based on selection of radio button, i want to change the text box to enable and disable. And additionally, how to set if i enter a value in textbox1 then calculating something and display the result in textbox2 that to on key up.. not on form submitting.
View 4 Replies View RelatedI'm a real newbie with Javascript, but I'm having fun. I just bought the book, "Simply Javascript" (have only just cracked it so far). I'm reasonably familiar with PHP (I use a lot of it to do simple things). I'm a Web desinger and do custom CSS Websites (I'm fairly new to that too couple of years or more working with CSS and I've never done a table based layout.

But when the button is clicked, nothing will call the showCaption() function again, and I can't figure out how to call that function as the images advance. I have tried a lot of things with a lot of weird results, one being the tne next caption will display in a blank browser window, without the Webpage! I'm not sure why that happens, but I have a clue.
Is there an easier way to do what I want to do? I only want to show a few lines of text that will describe each image. Seems simple enough to me, but I'm just too new to make it work.

Is it possible to use Javascript to dynamically change the PHP file used for an include?
For example, if I have a php doc like

I have been looking for this all day - Change currencies throughout the page when choosing between countries or currencies from dropdown menu. What I basically need is a dropdown menu which shows countries or currencies. When you select anyone of it like USD all the prices throughout the page are changed to USD. Now if you change it AUD/CAD/PKR etc they will be changed accordingly.
A very good example of this is: [URL]. When you change currency from right top dropdown menu - it changes the currencies of all the packages in the main content. I am a HTML developer and do not know much about javascripting. I have searched codingforums too and found only two links which are not of my use because they are currency converter:

I have two monitors (one wide screen, one square) attached to my computer I can verify how it will look in different resolutions.While doing so I came across a nasty thing: in some resolutions the content div is very small and not using all of the full browser window (left after the header section).Is it possible to make a change to the CSS min-height and max-height while the page is being loaded?I've looked into lots of samples but all depend on a click or mouse over event and didn't want to work with onload in the body tag.

I can think of doing it through mutation event DOMNodeInserted but the issue is they are not supported by all browsers and they are getting deprecated too.
What is the correct way to call a javascript function on the creation of elements in DOM so that page renders with the correct value.
I've set the page up with an iframe because I figured then I would only have to update menu links on that main page and then there'd be less chance of missing a link somewhere along the way as new updates are added. I know this could probably be accomplished with .css, but I don't know how to do that either!
My problem is that the iframe won't adjust height to allow for the longer pages without adding scroll bar. My neighbor doesn't want it to look like its a separate box at all, so no borders and no scrolling can be used. I've tried the various solutions I've found online and either they do nothing or they stretch the page that's loading in the frame to ridiculous proportions AND still adds a scroll bar.
As I said, I haven't designed in several years and I never learned JavaScript at all. I suspect my problem is probably due to not understanding which bits of code I need to change to my iframe name. The IFrame SSI IV totally confuses me, though I do think that's the one that would ultimately work if I just knew where I was supposed to plug in my iframe name and target info.
My iframe name is, quite simply, "content" and the first page I want loaded (when someone first visits the site) is "whatisreiki.html" (my neighbor does Reiki on animals). The site is www.lovingtheanimals.com but I am working on this particular issue on www.lovingtheanimals.com/iframetest.html so that I don't totally screw up the site where visitors might be affected.
