Calculating Values Of Columns And Rows According To Formulas?

Sep 26, 2010

calculating the summed values of a column. Also, the row values are subtracted from each other eg:

col1 col2 col3
row1 a b = a-b
row2 c d = c-d
row3 =a+c =b+d =a-b+(c-d)

however there can be N number of rows. I have listed below and example I have done to calculate the subtracted values but I am having difficulty doing the summations.

<table width="362" border="1">
<tr>
<td width="91"> <input name='r1c1' onblur='function update_Total_r1c()' size='6' value=""> r1c1</td>

[Code]....

JQuery :: Validate Matrix Columns And Rows?

Mar 3, 2011

I'm trying to validade a table that has 20 checkboxes (5 columns and 4 rows) and that needs to have at least 2 checkboxes checked in each row and column.I've managed to create the validation for the row part (all checkboxes in the same row have the same name).I've also created a custom class rule (all checkboxes in the same column have the same class) but it doesn't seem to work. It only shows the row validation messages (labels that are display next to the last cell in each row) and not the column rule message.

Here is the code:

<form class="form_matrix" id="form_matrix" method="get" action="form_matrix_submit">
<table><tbody><tr><th></th><th id="col_1">Col. 1</th><th id="col_2">Col. 2</th><th id="col_3">Col. 3</th><th id="col_4">Col. 4</th><th id="col_5">Col. 5</th><th></th></tr>

Switch Table Rows/columns With DOM (firefox Issues)

Nov 17, 2005

I want to switch entire rows/columns around in a table. Move rows up/down and move columns left/right. This works fine in IE/opera but has a few problems in firefox.

First of all, is this the 'right' way to do this or is there a better way? Firefox doesn't support swapNode().

When moving rows up/down (top one in demo) firefox takes a few clicks to work when it should be one click on the button. I have no idea why. Code:

Calculating A Score From A Row Of Drop-down Values

Aug 11, 2006

I need help in calculating a score from a row of drop-down values.
I need to use the onChange to tally the score as the user moves across
9 categories (with drop-down selection of 1-9 or N/A) multiplied by a
weighted score. The final column for each employee would be the
calculated score. I know how to accomplish this with vbscript but I
need it to process on the screen so the user can see the calculated
score as they make selections. Also the code needs to execute as many
times as there are employee rows.(loop) I don't know how to do this
with Javascript

Here's the VBscript with the variables involved
Var S1 = Category 1 Weighted score
Var S2 = Category 2 Weighted score
Var S3 = Category 3 Weighted score
Var S4 = Category 4 Weighted score
Var S5 = Category 5 Weighted score
Var S6 = Category 6 Weighted score
Var S7 = Category 7 Weighted score
Var S8 = Category 8 Weighted score
Var S9 = Category 9 Weighted score
D5 = 0.92
Var Q11 = Category 1 drop-down Value(1-9) * S1
Var Q22 = Category 2 drop-down Value(1-9) * S2
Var Q33 = Category 3 drop-down Value(1-9) * S3
Var Q44 = Category 4 drop-down Value(1-9) * S4

If (Category 5 Value = "N/A") THEN
Q55 = ' '
Else
Var Q55 = Category 5 drop-down Value(1-9 or N/A) * S5
End If

Var Q66 = Category 6 drop-down Value(1-9) * S6
Var Q77 = Category 7 drop-down Value(1-9) * S7
Var Q88 = Category 8 drop-down Value(1-9) * S8
Var Q99 = Category 9 drop-down Value(1-9) * S9

If (Category 5 = "N/A") THEN
Var FinalScore = round(((Q11 + Q22 + Q33 + Q44 + Q66 + Q77 + Q88 + Q99)
/ D5),2)
else
Var FinalScore = round((Q11 + Q22 + Q33 + Q44 + Q55 + Q66 + Q77 + Q88 +
Q99),2)
end if

Can anyone help me converting this to javascript?

Exploding Values And Calculating Totals ?

Apr 1, 2009

I have a slight problem with creating dynamic quotes. Basically I have two select boxes and need to calculate a total in real-time using javascript and insert into input.First it needs to explode out the machine price and term years from the values and then calculate.

Here an example: A machine costs �4000 and a term of 2 years(60 months). The calculation would be (4000/60)*3 = �200

<select name="machine">
<option value="2005 - Almida XAS47 (660 Hours) �4000">2005 - Almida XAS47 (660 Hours) �4000</option>
</select>[code].....

Calculating Root Values Beyond Math.sqrt

Dec 14, 2007

Well, it's been a while since I last visited CF, but I'm finally back and, for the life of me, am drawing a total blank on something that seems like it should be fairly easy to handle.

The Math.sqrt() function works just fine if all a person needs is the Square Root of a number, but what about needing the Cube Root or even a 4th Root of a number?

My first instinct was to use the Math.pow(x,y) function with a negative value for "y." For instance;

var z=Math.pow(27,-3)

This should return a value of 3. Unfortunately, this doesnt seem to work when I tested it through the W3 reference pages, so I am looking for a clue as to how I might go about finding such values, or if it is even possible through Javascript.

Editable Table - With Editable Rows And Columns That Will Feed Back Into A Database

Aug 12, 2009

I'm trying to implement is a table with editable rows and columns that will feed back into a database. If I could do it with AJAX that would be great too, but I'm not too familiar with javascript. I don't need the code, I need more of an idea. The HTML Table is currently a recreation of the MySQL table minus a few columns. Its all in text, but if I could make the text editable, or better yet, make the text turn into input boxes it would be really cool. I'm not really sure what kind of methods and properties I would need, or quite how to put it all together. What do you think is the best way to go about the entire project?
