Hi friends,
I am able to create a row dynamically with 3 cells(i.e column).
In my 3rd cell i need to add another row. Is it possible to acheive it. I am using Java script for it.
This is the table structure:

<table align="center" id="msgfield" width="100%" cellpadding="1" cellspacing="0" border="1"   bordercolorlight="#999999" bordercolordark="#FFFFFF" bordercolor="black">
								
								<tr class="tableDataTextStyle">
									<td width="15%">
										<html:text property="alertFieldName" styleClass="textBoxStyle" size="12" maxlength="50" readonly="<%=readOnly%>"/>
									</td>
									<td width="15%">
										<html:text property="alertFieldStartPos" styleClass="textBoxStyle" size="12" maxlength="50" readonly="<%=readOnly%>"/>
									</td>
									<td width="13%">
										<html:text property="alertFieldLength" styleClass="textBoxStyle" size="10" maxlength="50" readonly="<%=readOnly%>"/>
									</td>
									<td width="35%">
										<table align="center" width="100%" cellpadding="1" cellspacing="0" border="0">
											<tr class="tableDataTextStyle">
												<td>
													<html:select property="alertFieldFormat" onchange="selectFormat();" styleClass="tableDataTextStyle1">
														<html:option value="">Select</html:option>
														<html:option value="Decimal">Decimal</html:option>
														<html:option value="Masking">Masking</html:option>
														<html:option value="Date">Date</html:option>
													</html:select>
													
											</tr>
										</table>
										<table id="decimal" width="100%" border="0">		
											<tr  class="tableDataTextStyle">
												<td>Decimal Point </td>
												<td><html:text property="alertFieldLength" styleClass="textBoxStyle" size="10" maxlength="50" readonly="<%=readOnly%>"/></td>
											</tr>
											<tr  class="tableDataTextStyle">
											<td>Decimal Format</td>
												<td>
													<html:select property="alertFieldFormat" styleClass="tableDataTextStyle1">
														<html:option value="">Select</html:option>
													</html:select>
												</td>
											</tr>
										</table>
										<table id="masking" width="100%" border="0">		
											<tr  class="tableDataTextStyle">
												<td>Masking Text </td>
												<td><html:text property="alertFieldLength" styleClass="textBoxStyle" size="10" maxlength="50" readonly="<%=readOnly%>"/></td>
											</tr>
											<tr  class="tableDataTextStyle">
											<td>Mask Position</td>
												<td>
													<html:select property="alertFieldFormat" styleClass="tableDataTextStyle1">
														<html:option value="">Select</html:option>
														<html:option value="L">Left</html:option>
														<html:option value="R">Right</html:option>
													</html:select> 
													<html:text property="alertFieldLength" styleClass="textBoxStyle" size="1"  readonly="<%=readOnly%>"/>
												</td>
											</tr>
										</table>
										<table id="date" width="100%" border="0">		
											<tr  class="tableDataTextStyle">
												<td>Source Format </td>
												<td><html:text property="alertFieldLength" styleClass="textBoxStyle" size="10" maxlength="50" readonly="<%=readOnly%>"/></td>
											</tr>
											<tr  class="tableDataTextStyle">
											<td>Output Format</td>
												<td>
													<html:text property="alertFieldLength" styleClass="textBoxStyle" size="10" maxlength="50" readonly="<%=readOnly%>"/>
												</td>
											</tr>
										</table>

Hi,

if you need to add new element inside the table, simply insert new line of this:

// Adding new row
var newRow = tBody.insertRow( -1 ); // This will automatically add new row inside the table.
// Adding new cell on newly created row
// you can try to perform a new loop procedure.
for ( var n = 0; n < tLen; n++ ) {
addRow( newRow, "new Text #" + n );
} // Loop ended
 
// Adding new cell on a target row.

var r1 = tBody.rows[1 /* row index */];
r1.insertCell( -1 ).appendChild( document.createTextNode( "R{1} C{" + r1.cells.length + "}"));

make sure that when you add new bits of code, it is outside of the two loop that i've provided on this demo.

Hope it helps...

Inserting a new table-row inside a table-cell is not a legal move. Instead you can create a new table collection inside the table-cell of your choice:

// Refer on created elements inside the table.

var row1cell1 = table.rows[ 1 ].cells( 1 ); //R1C1

var row1cell2 = table.rows[ 1 ].cells( 2 ); //R1C2

// Append a new table inside R1C1
var newTable = addElement("table");
row1cell1.appendChild(newTable);
// But doing so, will require new implemeations over the created table-body.

// declare a collection of elements' for the new table-body 
var newTbody = addElement("tbody")

newTable.appendChild( newTbody );

var newRow = newTbody.insertRow(-1);
   for ( i = 0; i < yourNumberOfCell; i++ ) {
addRow( newRow, "new Cell" );
} // and so on...

// change the content of the text inside R1C2

row1cell2.innerHTML = "Change Text";

NOTE: that nesting table inside another table is not implemented in W3C standards for web structure

You can keep the same instance of my last posted code: var r1c1 = table.rows[1].cells( 1 ).style.backgroundColor = "wheat"; or if you just want to apply all the style rules in a single stance:

the style is working fine. I tried adding an onclick event to a cell like
oCell.onclick.action="removeRow()";
and i also tried
oCell.onclick.innerHtml="removeRow()";

can u suggest some solution for this

essential 84 Posting Shark Featured Poster · Answer 6 · 2009-07-29T13:57:26+00:00

Use this format:

// Table Row (Range 1);
var row1 = table.rows[ 1 ];

// installing onclick event in cell1 inside row1.

row1.cells( 1 ).onclick = function() {

// use this format if you want to change the text content of this cell.

/* 
this.innerHTML = "<b>Remove</b>"; // using innerHTML method.
or 

this.innerText = "Remove"; // using innerText method
*/
 
// Removing cell 1 in row 1 

row1.deleteCell( this.cellIndex ) || row1.removeChild( this ); 
};
