Setting Table Cell Width In Javascript

Nov 14, 2007

I've created a table in HTML but I need to specify the cell width client side. I need to loop through the cells and set the size based on the rendered size of some other elements.

I'm using the following doctype <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

This is causing me problems in Firefox. The width attribute is being set correctly but the actual table cells aren't being resized. Has anybody seen this before and does anybody have a workaround?

Place A Javascript Menu Inside A Cell Of A Table.

Jul 23, 2005

Im trying to place a javascript navigation menu inside a cell of
a table in my page, the problem is that the constructor of the menu
object has parameters for menu positioning and size and when the
window is rezised the menu stands at the same position and with the
same size.

My question is: is there a way to modify those parameters
dinamically to match window size, and how is that made, or is there
another way to include that menu using a table for page layout.

How To Read/modify A Cell Of A HTML Table With A JavaScript

Nov 10, 2005

I'd like to read and modify a cell (e.g. 'Text 1') in the following HTML table with a javascript:

==============================================

<html>
<body>
<table id = "MyTable">
<tr id = "Row1">
<td width = "40%">
Text 1
</td>
<td width = "60%">
Text 2
</td>
</tr>
</table>
</body>
</html>

==============================================

With
var table = document.getElementById("MyTable");
I can access the table and with
... table.rows[var_tabelle.rows.length - 1].firstChild

I can somehow access the row. But I can't read and also not change the
content.

Using Javascript To Change Table Cell Background Image

May 15, 2003

I'm trying to be tricky and its not been working LOL. I have a gallery page with lots of thumbnails that load up. What I wanted to do was have a "LOADING IMAGE" GIF in each of the table cells so that the user would see visually how many more images were going to load up. That bit is fine but when all the thumbs have loaded I want to change that Cell background image to something else.

How would I do this? Would I be able to reference them all at once or would I have to reference each individual cell one at a time.

To better illustrate my point see this this link :

Cannot Move Input Focus To A Cell After Re-Defining The Cell

Sep 15, 2011

I have a javascript program that uses a HTML table as an Excel-like grid. The user can use arrow keys to navigation the grid. When the user selects a cell and then hits <Enter> key, the program turns the cell from read-only to editable (an input box), and select all the text in the input box. When the user hits <Esc>, the program cancels the changes that the user has made and turns the cell back to read-only. So far so good. The problem is that as soon as the user hits <Esc> key and turns the cell back to read-only, I find that I cannot move the input focus back to the cell any more. Actually I cannot move the input focus back to _any_ cell in the table. When this happens, the user cannot use arrow keys to navigate the grid any more (like the grid has lost the input focus). The user needs to use the mouse to click at a cell in the table to get things working again.

The user can get around with this problem by un-selecting the text from the input-box before hitting <Esc>. But this is not something that I expect the user to remember to do. I need a way to fix this problem. I tried the logical thing and programmatically un-select the text before turning the cell back to read-only. But this actually made thing worse - this causes the workaround to stop working.

The only browsers that I have tested this program is IE6 and IE8. I have not tested this in any other browser.

Attached is a simplified version of the program that can show this problem in action. This simplified program first adds an empty table on the web page, and then creates an instance of the CEstGrid class that takes care of the grid. CEstGrid will add two rows of test data into the table with two columns in each row. The user should use a mouse to click at one of the cell, and the cell should be highlighted. The user uses arrow keys to navigate the table. When he reaches the end of the table, he will wrap around to the other side of the table. Let say the user reaches the cell in row-1 column-2, he hits <Enter> to change the cell to editable. He will find the text in that cell to be highlighted. When he hits <Esc> at this moment, he will find that he cannot use the arrow keys to navigate the table any more, and this is the problem. Please rename the test program from .TXT to .HTML to test it.

Creating A Code Generator In Javascript - Is It Possible?

Feb 21, 2007

I have seen quite a few code generators over time where you are presented with a form, you fill in the various fields in the forum, and then click a Generate Code button, and the results show up in a textarea.

The code is then copied from the textarea and pasted into notepad or directly into an HTML document.

So, you may have some code that you want to generate that looks like this:

In this particular case there is 1 .js files that go to the root of the site that requires no editing.

Then there is 1 .css file that may require changes depending on user preferences. Things like margin, width, height, border and so on.

Then there is a section that goes into the Head of the document that requires no changes.

Then there is something like this would go inside a division"
<a href="address to a page" target="an iframe name"><img src="path to thumbnails/thumbnail name" border="1"></a>
Note that the above code has variable that would change based on user preferences. The way the code is presently structured it is not done as an array, however, this would substantially shorten the code depending on how many thumbnails are in it.

And finally there is another iframe section that would go inside a couple of a division. It relates to a second iframe.

Before I go any further with this, I just wanted to know if it's possible to do with javascript or is it best to do in another language.

The variables don't have to be kept in a database. What I am thinking is that the user would simply open up the HTML page, enter the data, generate the code, copy/paste and test, without closing the page. If there is a problem, he/she would simply go back in and change a variable or 2 and re-generate the code.

Creating A Link With A Javascript-read XML Page

Oct 24, 2005

I have an XML document which lists some information about movies(Title, actor, etc.) I am using Javascript to pull that data and display it as html. Is it possible to create a link for each one of those titles that are pulled from the XML in my JS? Here is my code:

for (var i=0; movies.length > i; i++)
{
var Title = movies[i].getElementsByTagName("title");
var Actor = movies[i].getElementsByTagName("actor");
var Price = movies[i].getElementsByTagName("price");
results += i+1 + '. ' + ' "<span class="title"><a href="http://www.imdb.com">' + Title[0].firstChild.nodeValue + '</a></span>"' +
' starring <span class="actor">' + Actor[0].firstChild.nodeValue + '</span>' + ' and costs approximately $'+ Price[0].firstChild.nodeValue + "<br/>

";
}

document.getElementById("displayresults").innerHTML = results;

Creating A Product Like Google Analytics With JavaScript

Aug 7, 2007

I've noticed that Google uses JavaScript to pass information to their servers for processing. I can only imagine they're passing back the HTTP request of the current request to pull the data from to track sessions, page views, time spent, etc. Does anyone have an idea of how they're actually doing this?

Change Border Of Some Cell By OnMouseOver Different Cell?

Apr 11, 2010

imagine table with 15 rows and 3 columns. If I move mouse over any cell I want some other specific cells to change their borders like with pseudo-class :

example

<style>
.boryellow {border: 3px solid yellow}
.borblue {border: 3px solid black}
</style>

this will work, a cell can change itself

<td name="third" class="boryellow" onmouseover="this.className='borblue'" onmouseout="this.className='boryellow'">cell</td>
even when dealing with empty images - click on link will change border of different element - imgs, but not span or td ...
<a href="#" onclick="document.all.xxx.className='borblue'; document.all['name'].className='borblue';

[code].....

Replacing any element link by "third" or "spanx" will cause stuck ant not executing other actions.

Creating Generic Javascript Functions (ie. El.onmouseclick = Function ...)

Jan 8, 2007

I want to learn more about creating functions for element events
without having to put onclick event in every tag. For example:

<script>
document.getElementsByTagName('input').onclick = function () {
alert('hello');
}
</script>

Now, I know the above does not work as I have tried it but hopefully
the idea of what I am trying to achieve here. Basically for every input
tag, when the user triggers the event (click) it will do the same
function.

Anyway, I would more so like to learn about this type of scripting
where you assign functions to events. However, I dont know what to
search for in google and the like. Where could I learn more about this?

Mar 1, 2006

i am having a problem creating a javascript function to swap my radio values based on the first set one.

i have a bunch of radio buttons on the page which are like this:

Code:
<input type="radio" name="add_id[1]" value="yes" CHECKED>Yes <input type="radio" name="add_id[1]" value="no">No
<input type="radio" name="add_id[2]" value="yes" CHECKED>Yes <input type="radio" name="add_id[2]" value="no">No

DOM Row/cell With InnerHTML

Jul 23, 2005

I've got this code that creates a new new row and cell. I then put some
text into the cell with innerHTML - works beautifully with Firefox but
fails with IE. I guess IE doesn't support this way of doing it, but is
there another way of doing it with DOM?

newr = document.createElement('tr');

stbl.appendChild(newr);
newc = document.createElement('td');

newr.appendChild(newc);
newr.cells[0].innerHTML = (nr+1)+". "+sa[ti][nr + 1]+"<br><hr>";
(works in firefox but fails in IE 6+ too...)

How To Set Text In A Cell

Jul 23, 2005

My web page has thumbnail pictures, and when the user clicks on a
thumbnail, I change the image source of a full-size image elsewhere on
the page. I'd also like to change the caption of the full-size image,
but I'm not sure how to set the value of the text. I've tried creating
a form with a single input field, and I can set the value of that
field, but the field has a sunken style that I can't get rid of, and
I'd like to find a different way of displaying the text.

Is there an easier way to change the value of a text field?

Get A Cell From A Selected Row

Feb 18, 2010

I have a table and i want that when I select a row (onclick event) two functions to be called.

This is the code (it is PHP generated):

The first onclick function (named colorChange) works, but the later does not.

I don't know why is that. I used this configuration before and it worked.

So.. the js function that does not work is this (it shows me no alert):

I repeat that the first function (colorChange) works, and it is put in the same place (file) as the above one.
