 function cal()

{

    var f = document.form1;

    var regExp_Count = new RegExp("^[0-9)(-]+$");

   f.price1.value = parseFloat(f.baseprice.value*(f.percen.value/100)).toFixed(0);

}

cal() functions , will calculate as such in that formula n display in the price1 text
using the text property onblur,

<input id="percen" name="percen" size="6" maxlength="2" onblur="cal();" onkeyup="valid( this,'notnumber s')" type="text" />

this used to further added two input text , Problem Area ,
<a href="javascrip t:addRow()">Add Row</a>

addRow() functions which adds two input text control ,
cell1 couldnt able to calculate , and display on the cell2 .as it did on the other input text control

i Think these lines giving an issue ,
percentage.onbl ur='cal()'
percentage.onke yup=valid(this, 'notnumbers')

some times with onkeyup event , it shows "error on page" on the status bar .

plz Suggest ....

Hi all, Just wondering how to write (using document.write) to a table cell. I have table with 3 rows and 3 colums. I want to write from within the Javascript to say third column of a first row. How do I do it? I think one way is to write the entire table out in document.write("<table>...) but I'd like to know if it is possible to access a particular cell in a table.

empty table cell to be used as link

by: Greg N. | last post by:

Hi folks, I have a table cell with a background image, something like <td background=landscape.jpg height=200></td> The sole purpose of this code is to display the image inside that table cell. It displays just as much of the image as the current cell width allows. The actual cell width is determined by other cells in the same table column and by the current browser window width.
