How To Read The Contents Of A Cell
Jul 16, 2009
I need to make a javascript that when I am at a page within a game I play and click the javascript, it will get the value of a table cell, separate them to x and y variables and then put the values into a link that opens. The open link is of a php script that uses $_GET for the values of the variables to query my database.I am terrible at javascript and have been trying to do this for 2 days now with no success.Here's the scripts so it is easier to understand:This is part of the html page that is from the game. I need to have the javascript get 432|608 and assign x=432 and y=608 in this case, although those number change, the place in the table that that they are displayed do not change.
<td>Coordinates:</td>
<td><a href="game.php?village=19392&s=map&x=432&y=608">432|608</a></td>
<html>

Is it possible to read the contents of a table cell. I have the below table and would like extract the value of the first cell. The first cell will always be a hyperlink so I guess I only need the contents between the "<A>" tags. So the first row should return ""434235". How can I do this.code...

I would like a simple table where the user can hover over one of several small cells, and the contents of the main cell changes. An example can be found on the Virgin.net Website right in the middle of the page.
Can someone point me in the right direction?

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.

I have a page containing an external javascript which loads an image
onto the webpage. How would it be possible to use javascript to read
the filname (and the dimensions) of the loaded image (something I can
get by right-clicking the image with the mouse, but it is not given in
the source of the page).

How could I apply a css style to a <tr> row based on the value of the contents in column 1?
For instance, on my table (generated from an asp:GirdView), column 1 contains a number ranging from 1.00 to 12.00. I need to show a certain background color for all rows whose value in column 1 is greater than 10.

I am using jQuery with jEditable and jQuery UI confirmation dialog. What I am trying to do, it to restore contents of the table cell if user hits Cancel on jQuery UI dialog, or just hits Esc.jEditable has "onblur" option that i can set to "cancel", and it works if uses clicks out of the field, so I am trying to achieve something like that with jQuery UI, because currently it just leaves an empty table cell.
I am pretty sure the logic of my script is wrong somehow, so I am trying to figure out what to do to fix it.
Here is the flow of the script:
1. User clicks on a table cell and edits data in jEditable
2. User clicks save, jEditable doe POST to my php script and gets results, which a passed to jQuery UI confirmation dialog.
3. User either confirms or cancels changes. In case of Cancel or Esc, the user presented with a page, as it was before any editing has occured
-i
$(".editable_textarea").editable("/path/to/my/php_script.php", {
indicator : "<img src='/am/images/indicator.gif'>",
type : 'textarea',

I can read the contents of an iframe:
HTML Code:
var iframe = document.getElementById("message");
var iframeContents = iframe.contentDocument.body.innerHTML;
var txtarea = document.getElementById('message2');
txtarea.value = iframeContents;
This will read the contents of an iframe, and write it to a textarea.
iframe is editable, and content is entered by the user. Still, this works.
But, below code is not working. Trying to put some content to an iframe, with the same innerHTML method above. It returns no errors or warnings. Even last alert() displays "<div>lorem ipsum</div>", but iframe is empty, it displays nothing..
HTML Code:
var textContent = "lorem ipsum";
var iframe2 = document.getElementById('message');
iframe2.contentDocument.body.innerHTML = '<div>'+textContent+'</div>'
alert(iframe.contentDocument.body.innerHTML);

On my index.htm, I have a horizontal cell named "memberarea" which originally shows username & password input fields. After the user logs in, this area changes itself to a "Welcome Name, Lastname" field. I want that this cell displays again the username and password input fields in case of the session of the user has expired. I have tried it with the following code (within the Iframe in index.htm):

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.

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.

I'm looking for javascript to analyze the contents of a textbox and replace the contents with the appropriate date. To make that a little clearer, if the user types 'tomorrow' then when they tab/move onto the next text box the 'tomorrow' text should be replaced with the date for tomorrow in the format dd/mm/yyyy, if the user enters '1 week' then the text should be replaced with the date in one week in the format dd/mm/yyyy etc.

I have a simple HTML table that I want to use as a progress bar - by
changing the width of the two TD elements with javascript, you show
progress. The problem is that when I change the width to 100 and 0
resp., you still see a sliver of white for the right cell... any way
to do this, it's drivin me nuts! I tried also changing the back color
of the right cell to blue when it hits 100, but it only works in
Mozilla/Firefox, not IE....

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...)

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?

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.
