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?

JQuery :: Table Cell Width Is Incorrect?

Oct 19, 2010

However, I finally ran into a problem that I can't figure out. When I try and get the width of any cell in a table it's returning a width of 83 or 84. I have the table inside a div that has a width of 757px. I don't have a width set on the table itself, but each cell is set to 100px. I've tried to set the width in a css file and inline neither of which give me the 100px that I'm thinking it should return. I've tried both width(), outerWidth() and innerWidth(). The only one that returns a different number is outerWidth.

Get The Width Of Table Cell(s) That Have Been Dynamically Built

Nov 21, 2003

To build a horizontal floating menu that matches the first row (header row) of my dynamically built table (to include text and cell height/width - needs to match exactly). I have accomplished 90% of this task by extracting the text and building the row in my floating menu header and placing the floating menu where it needs to be. However, I'm having a problem aligning the table (<TD></TD>) cells because of my dynamically built table.

Scenario:

I have a table that is built dynamically. Before it is displayed, I format the table row data (code that adds text/deletes rows etc…), which alters the width of all the table cells (via JavaScript). We'll call this (for lack of a better phrase) "pre_floater_table_format_code."

I then loop through the DOM (<TD></TD>) in the first row of the table to get the text and width from each cell (using offsetWidth and/or clientWidth) and assign the text and cell width(s) to variables that I use to build my floating menu with. We'll call this (for lack of a better phrase) "get_cell_text_width_code."

Problem:

The problem is that once the table is built (and before it is altered by the "pre_floater_table_format_code") it seems as though my "get_cell_text_width_code" reads the un-processed table cell width(s) and sets these variables to the un-processed width values. The "pre_floater_table_format_code" runs much earlier than the "get_cell_text_width_code." So why wouldn't the "get_cell_text_width_code" read the cell width(s) after they've been adjusted by the "pre_floater_table_format_code?" Does this make sense? Anyone have any recommendations? Alternative solutions?

Dynamic Table, Setting V-align Of A New Cell

Jul 20, 2005

I am working on something that only needs to work in IE, and I've got
this code:

var aRows=oTable.rows;
var oCell1_1=aRows(0).insertCell();
oCell1_1.innerHTML= 'new cell'

Which inserts a row in my table and I can populate the cell with the
text using the innerHTML property. No problem.

My question is, how do I set the VALIGN of this new cell?

I have tried this..

oCell1_1.valign='top'

and that does not generate a JavaScript error but it doesn't
vertically align the text in the cell either.

Other attempts generate javascript errors.

Setting Table Cell Style Attributes

Jun 19, 2007

given a cell from a table...
function Tbl_GetCell(tbl, row, col)
{
var theRow = tbl.getElementsByTagName("tr")[row];
return theRow.getElementsByTagName("td")[col];
}

I can set attributes like width, height, and align, but how can I set cell style info?

cell = GetCell(tbl,row,col)
these work fine... cell.align = "center"; cell.height = 22;
but this doesn't... cell.style = "font-weight: bold; text-decoration: blink"

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 :

IE's Cell-width / Colspan

Dec 20, 2005

Basically in IE, if a CSS width is defined for a cell (<td> element) as well as having a colspan attribute allowing the cell to span more than one collumn, the cell (eg the border etc.) will occupy the width*colspan but the content will only occupy the width.

Setting Focus To A Tabe Cell.

Sep 14, 2006

There is a tab control on a page with multiple tabs and handful of
controls in each tab. The way it's rendered in html (like grid etc..)
is in table format in tablerows and cells.

On clientside, on form validation in javascript, I would like to set
focus on to one of the tabs
and set the focus to the control on that tab.

I find this (tab) control by looking through all 'td' s and by it's id.
Now that I have "td" control, I would like to set the focus on to this.

Here is what I do. (FindHtmlControlByID method returns the control based on type and id)

firstTab = FindHtmlControlByID('TD','UltraWebTab1td0');
secondTab = FindHtmlControlByID('TD','UltraWebTab1td1');

secondTab.style.visibility = 'visible'
secondTab.focus();

textBox = FindHtmlControlByID('INPUT','uiTextBox1');
textBox.style.visibility = 'visible'
textBox.focus();

textBox.focus() fails with the message it's either not visible or not
enabled or it is a type of control that cannot be focused. If the tab
already had focus, then this works ok.

JQuery :: Setting Width And Height For Dialog

Jun 9, 2009

I have always been using Prototype but I finally made the switch to jQuery because of its good documentation and large user base.

I have a problem that I hope someone can solve. The problem is that I cannot correctly set a size of my dialog when loading the content using Ajax.

I have the following code:

The content is loaded but the dialog is not sized properly. I guess that it depends on the content being changed after the dialog has been initialized. Is there a nice way to solve this problem?

I tried the following solution (not very good looking but anyway...)

This causes the size to be correct but it doesnt center the window and it also removes scrollbars from the content. I must have the scrollbars but I want the dialog not to exceed the viewport.

Another solution is to download and use YET ANOTHER third party plugin but hey comeon, shouldnt jQuery UI be able to do this?

Triple-click Combo Box After Width Setting

Jul 6, 2010

I am expanding the width of a combo box when focusing on it, but what I am running into is that with IE, setting the style.width on focus causes me to have to "triple-click" when selecting an option. This works fine in FF and Safari. Here is the bare bones of what I am trying to do...

[Code]....

After you open this, make sure focus is in the text box... click the combo, which will expand in width... then try to select something... it will take two more clicks. Three total! Use IE.

Table Cell Properties

I don't see anything about table properties in the book. (I would like
to try to write a script so that the background color in a cell in a
table changes color (between two or three specified colors)). How do I
get at the background color property in a table cell?

JQuery :: Get Row X, Cell Y From A Table?

Oct 27, 2009

I have googled until my fingers bled and can't get a working answer to what I expected to be a fairly simple, common problem (but I guess not): I need to get the text value from row 5, column 3 of a table.

The user isn't clicking on the cell or the row or the table or anything like that. The table is dynamically built from the server side and I can't assign an id to either the row(s) or the cell(s), but I do have a table id and a table body id. How do you retrieve text given a specific row and column index?

Copying A Table Cell With No IDs?

I'm working on an iPhone application that extracts data from a website using Javascript and displays it in a more user-friendly text box. Everything works fine and dandy, however, now that I've come up to the last element, I need to extract text from a table on a website.Basically what I want to do is find the balance, in this case '$17.28' from 'results_table', and have that stored in a variable. I've looked around on google with no real luck.

Code:

How To Highlight Table Cell On MouseDown?

I have set up an HTML table with clickable cells (the cells contain
only text). They work fine, but I would like to give the user some
visual feedback to indicate that a cell has been clicked. I'd like
this feedback to be the usual highlight on mouseDown, un-highlight
on mouseUp, but I can't figure out how to do it.
