Hi All,
My requirements are
1. Screen where user enters the no of rows(no of columns:4 Sl no , Start Date(SD), End Date(ED), Label)
2. user clicks on button to create the table (dynamic)
4. Si No should be done through function .
5. SD/ED/Label should be free text.
6. Validate StartDate/ EndDate .(only Date or time should be entered.
7. no validation for label column.

Should be done using dhtml/javascript

Thanks in Advance.

Hi

You say you are programmer. Then certainly you already put together some code for that. Show it, then we will correct it.

Please note that we will not do your job. We are here to help each other, not to work for free.

I am sorry for not posting my code..

Here is my code.
////code starts
function createTable(rowCount, colCount, srcHolder)
{
document.getElementById('dynamic_tp_table_heading').style.display = "block";
document.getElementById('dynamic_tp_table').style.display = "block";
if(document.getElementById('time_period').value!="Shift"&& document.getElementById('time_period').value!="Select Time Period")
rowCount=1;
if(IsValidNumber(rowCount) && IsValidNumber(colCount) && (srcHolder != null) && (srcHolder.canHaveChildren))
{
srcHolder.innerHTML = "";
var srcTable = document.createElement("table");
srcTable.border = 1;
srcTable.borderColor = "Black";
// srcTable.height = DEFAULT_HEIGHT;
srcTable.width = 320;
var tmpRow = null;
var tmpCell = null;
srcHolder.appendChild(srcTable);
for(i=0; i<rowCount; i++)
{
tmpRow = AppendRow(srcTable)
for(j=0; j<colCount; j++)
{
tmpCell = AppendCell(tmpRow);
// tmpCell.innerText = j;
tmpCell.innerHTML = "<input type='text' value='' id='test' size='16' >";
tmpCell = null;
}
tmpRow = null;
}
}
}

//code ends

Thanks in advance.

Hi

Better. But incomplete.
[ul]
[li]We not know what elements are those with dynamic_tp_table_heading, dynamic_tp_table and time_period [tt]id[/tt][/li]
[li]We not know what IsValidNumber() function does[/li]
[li]canHaveChildren is Explorer-only, so your code will not work in standard-compliant browsers[/li]
[li]We not know what the AppendRow() function does[/li]
[li]We not know what the AppendCell() function does[/li]
[/ul]
Reducing your function to what we know, this works for me :
Code: 
[b]function[/b] [COLOR=darkgoldenrod]createTable[/color][teal]([/teal]rowCount[teal],[/teal] colCount[teal],[/teal] srcHolder[teal])[/teal]
[teal]{[/teal]
  srcHolder[teal].[/teal]innerHTML [teal]=[/teal] [green][i]""[/i][/green][teal];[/teal]
  [b]var[/b] srcTable [teal]=[/teal] document[teal].[/teal][COLOR=darkgoldenrod]createElement[/color][teal]([/teal][green][i]"table"[/i][/green][teal]);[/teal]
  srcTable[teal].[/teal]border [teal]=[/teal] [purple]1[/purple][teal];[/teal]
  srcTable[teal].[/teal]borderColor [teal]=[/teal] [green][i]"Black"[/i][/green][teal];[/teal]
  srcTable[teal].[/teal]width [teal]=[/teal] [purple]320[/purple][teal];[/teal]
  [b]var[/b] tmpRow [teal]=[/teal] [b]null[/b][teal];[/teal]
  [b]var[/b] tmpCell [teal]=[/teal] [b]null[/b][teal];[/teal]
  srcHolder[teal].[/teal][COLOR=darkgoldenrod]appendChild[/color][teal]([/teal]srcTable[teal]);[/teal]
  [b]for[/b] [teal]([/teal]i[teal]=[/teal][purple]0[/purple][teal];[/teal] i[teal]<[/teal]rowCount[teal];[/teal] i[teal]++)[/teal] [teal]{[/teal]
    tmpRow [teal]=[/teal] srcTable[teal].[/teal][COLOR=darkgoldenrod]insertRow[/color][teal](-[/teal][purple]1[/purple][teal])[/teal]
    [b]for[/b] [teal]([/teal]j[teal]=[/teal][purple]0[/purple][teal];[/teal] j[teal]<[/teal]colCount[teal];[/teal] j[teal]++)[/teal] [teal]{[/teal]
      tmpCell [teal]=[/teal] tmpRow[teal].[/teal][COLOR=darkgoldenrod]insertCell[/color][teal](-[/teal][purple]1[/purple][teal])[/teal]
      tmpCell[teal].[/teal]innerHTML [teal]=[/teal] [green][i]"<input type='text' value='' id='test' size='16' >"[/i][/green][teal];[/teal]
      tmpCell [teal]=[/teal] [b]null[/b][teal];[/teal]
    [teal]}[/teal]
    tmpRow [teal]=[/teal] [b]null[/b][teal];[/teal]
  [teal]}[/teal]
[teal]}[/teal]
Regarding your 4 column requirement, I would change my above function like this :
Code: 
[b]function[/b] [COLOR=darkgoldenrod]createTable[/color][teal]([/teal]rowCount[teal],[/teal] srcHolder[teal])[/teal]
[teal]{[/teal]
  srcHolder[teal].[/teal]innerHTML [teal]=[/teal] [green][i]""[/i][/green][teal];[/teal]
  [b]var[/b] srcTable [teal]=[/teal] document[teal].[/teal][COLOR=darkgoldenrod]createElement[/color][teal]([/teal][green][i]"table"[/i][/green][teal]);[/teal]
  srcTable[teal].[/teal]border [teal]=[/teal] [purple]1[/purple][teal];[/teal]
  srcTable[teal].[/teal]borderColor [teal]=[/teal] [green][i]"Black"[/i][/green][teal];[/teal]
  srcTable[teal].[/teal]width [teal]=[/teal] [purple]320[/purple][teal];[/teal]
  [b]var[/b] tmpRow [teal]=[/teal] [b]null[/b][teal];[/teal]
  [b]var[/b] tmpCell [teal]=[/teal] [b]null[/b][teal];[/teal]
  srcHolder[teal].[/teal][COLOR=darkgoldenrod]appendChild[/color][teal]([/teal]srcTable[teal]);[/teal]
  [b]for[/b] [teal]([/teal]i[teal]=[/teal][purple]0[/purple][teal];[/teal] i[teal]<[/teal]rowCount[teal];[/teal] i[teal]++)[/teal] [teal]{[/teal]
    tmpRow [teal]=[/teal] srcTable[teal].[/teal][COLOR=darkgoldenrod]insertRow[/color][teal](-[/teal][purple]1[/purple][teal])[/teal]
    [b]for[/b] [teal]([/teal]j[teal]=[/teal][purple]0[/purple][teal];[/teal] j[teal]<[/teal][purple]4[/purple][teal];[/teal] j[teal]++)[/teal] [teal]{[/teal]
      tmpCell [teal]=[/teal] tmpRow[teal].[/teal][COLOR=darkgoldenrod]insertCell[/color][teal](-[/teal][purple]1[/purple][teal])[/teal]
      [b]switch[/b] [teal]([/teal]j[teal])[/teal] [teal]{[/teal]
        [b]case[/b] [purple]0[/purple][teal]:[/teal] tmpCell[teal].[/teal]innerHTML [teal]=[/teal] i[teal];[/teal] [b]break[/b]
        [b]case[/b] [purple]1[/purple][teal]:[/teal] tmpCell[teal].[/teal]innerHTML [teal]=[/teal] [green][i]"<input type='text' name='SD["[/i][/green][teal]+[/teal]i[teal]+[/teal][green][i]"]' >"[/i][/green][teal];[/teal] [b]break[/b]

      [teal]}[/teal]
    [teal]}[/teal]
  [teal]}[/teal]
[teal]}[/teal]
Regarding the validation, tell us when you want the validation to happen.

By the way, personally I hate this approach. The user has to know from the beginning the number of rows. Is easier for the user to get a table with one row and a button to add one more row. The he can press the button when needed, as many times needed.

Hi Feherke,

I need to validate the start date / end date fields on click of submit button.

Hi

Next time please post your code between [tt][ignore]
Code: 
[/ignore][/tt] and [tt][ignore]
[/ignore][/tt] TGML tags.

For validation you need a function like this :
JavaScript: 
[b]function[/b] [COLOR=darkgoldenrod]validate[/color][teal]([/teal]what[teal])[/teal]
[teal]{[/teal]
  [b]var[/b] ok[teal]=[/teal][b]true[/b]
  [b]for[/b] [teal]([/teal]i[teal]=[/teal][purple]0[/purple][teal],[/teal]l[teal]=[/teal]what[teal].[/teal]elements[teal].[/teal]length[teal];[/teal]i[teal]<[/teal]l[teal];[/teal]i[teal]++)[/teal]
    [b]if[/b] [teal]([/teal]what[teal].[/teal]elements[teal][[/teal]i[teal]].[/teal]name[teal].[/teal][COLOR=darkgoldenrod]match[/color][teal]([/teal][fuchsia]/^[ES]D\[\d+\]/[/fuchsia][teal]))[/teal]
      [b]if[/b] [teal](![/teal]what[teal].[/teal]elements[teal][[/teal]i[teal]].[/teal]value[teal].[/teal][COLOR=darkgoldenrod]match[/color][teal]([/teal][fuchsia]/^\d{4}-\d{2}-\d{2}$/[/fuchsia][teal]))[/teal]
        ok[teal]=[/teal][b]false[/b]

  [b]return[/b] ok
[teal]}[/teal]
and call it like this :
HTML: 
[b]<form[/b] [maroon]name[/maroon][teal]=[/teal][green][i]"FilterPage"[/i][/green] [maroon]onsubmit[/maroon][teal]=[/teal][green][i]"return validate(this)"[/i][/green][b]>[/b]
That works for me together with the modified createTable() function I posted yesterday.

Note that you not specified what kind of validation you want, so my function just tests if the text in the [tt]input[/tt] is in ISO date format : 2010-12-22.

validation :

Start date/end date field will have time with am/pm when shift is selected.

Start date/end date field will have date with dd/mm/yyyy when day/week/month/year is selected.

Thanks for replying.
