How To Change Cell Background?

Jul 23, 2005

How can I change the background IMAGE (not just color) of a CELL in a table?

I know that I can do this using CSS, but I really need to be able to do it
using JavaScript. Anyone know how?

Must be able to change the image for each cell - not the whole table.

JQuery :: Any Way To Change Table Cell Background Color?

Mar 18, 2011

Is it possible to change a table cell background color or add any attributes based on a criteria, anyway, here's my scenario. I have a php table dynamically created onthefly, (let say on load), then i have a sql query returning some values. So illustrating:
Table: Sql Result
1 2 3 4 5 2 5 7
6 7 8 9 10

What I am trying to achieve is use the sql result to add attributes to the table cells so for the illustration say i want to add a bold attribute to all table cell which corresponds to the sql result, the result would be,
Result:
1 2 3 4 5
6 7 8 9 10
Any plugins out there? "Its php (server-side) and jquery (client-side) talking...but I know there is a way!

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 :

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.

Mouseover - Changing Background Color In Cell

Jun 25, 2002

Is there any way to have the background color change in a cell only when the mouse is over the link? This is what I have so far:
<td class=topnav2 onClick="location.href='AboutAD/overview.htm'" onMouseOut="this.style.backgroundColor='#9966FF'"onMouseOver="this.style.backg roundColor='#660099'" bgcolor="#9966FF" width="107" height="45"valign="middle">
<a class="topnav2" href="AboutAD/overview.htm">About Alzheimer's</a>
Currently you rollover the cell it changes color, I just want this effect when you roll over the text.

Image Swap By Thumbnails When In A Cell Background?

Feb 14, 2011

Looking for javascript, to do what i've hap-hazardly slapped together here: I'd like to do this without having to reload a page or create a new page for each image.

[URL]

Specifically the switching of the main image by the thumbnails. The difference in what i've seen online, is that i'm actually using them as a cell background.

Automatically Changing Background Color Of A Table Cell?

Jul 23, 2005

I'm the webmaster for a recreational organization. As part of one page of the
site, I have an HTML "Calendar at a Glance" of the organization's events for
the month. It's a simple table of a calendar, 7 across by whatever needed
down, and I manually create it each month - not a big deal.

Every day I go in and darken the background color of the current day's cell
by changing the appropriate <TD> entry to <TD bgcolor="c63800"> and uploading
the page. Takes well under a minute start to finish. Thus the calendar
gradually changes color over the course of the month, with the past dates dark
and the future dates lighter and thus more apparent to the eye.

But I have to ask if there's a nifty way in which this might be done
automatically, based on the current day and the number (the day of the month)
that follows the <TD> entry.

A typical "before" entry is

<TD>23<br>Peet's Coffee, Newport Beach<br><br>8 AM: Don<br>9 AM: Molly</TD>

and an "after" entry is

<TD bgcolor="c63800">23<br>Peet's Coffee, Newport Beach<br><br>8 AM: Don<br>9
AM: Molly</TD>

I don't pretend to be a javascript heavy, but can usually stumble my way
through a task given some words of wisdom. Is this "doable"?

How To Dynamically Change Text In A Table's TD Cell?

Jul 23, 2005

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?

Dynamically Change BgColor Of Table Cell?

Jul 20, 2005

Is there a way to dynamically (e.g. upon onClick) change the bgColor
attribute of a table cell? I tried cell.setAttribute("bgColor",
someColor), where someColor was a string of the form "#RRGGBB",
but nothing happened.

Also, how can I set the mouse cursor to be an arrow when it hovers
over these table cells? (It's an insertion bar now.)

Change Color Of Text In A Table Cell

Oct 10, 2011

I have a php script that displays database data in a web table. I also have a javascript code which is supposed to compare the value entered in a web form to that hard coded in the script and change the color to green if its below, amber if its equal and red if its greater than.

Below is my javascript code:

As you can see from my javascript, i am getting the elements by id (getElementById("color")). Currently, only the first <td> with id='color' is changing when the value is entered. How do I make the text in other table cells with id='color' change color when the comparison value is entered?

Change BG Color Of A Div By Clicking A Table Cell?

I basically want the background color of a div (banner) to change when the user clicks a green or blue table cell. So if they click the blue table cell, the backgound color of the div changes to blue (its green by default).

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.

Have A Div Change Its Own Background?

Jul 3, 2009

I'm pretty new at javascript. I came here with my last problem and it was solved quickly and really helped. Alas now I am stuck again.

I have a series of buttons on the stage, each with their own div tag with the same ID. The number of buttons will be dynamic based on the users account. When you click the button, I would like the background of the div tag, which contains that button, to change. I have no idea how to go about this. I've tried different approaches but none seem to be panning out. Is there a simple this.div function that I could call?
