View Full Version : validation in dom

11-22-2008, 01:04 AM
i m using dom for creating row in my existing table.
below is table code

<table class="DocumentLines" cellpadding="1" cellspacing="1" id="LinesTable">
<th rowspan="2">Product Code</th>
<th rowspan="2">Description</th>
<table class="DocumentLines" cellpadding="1" cellspacing="1">
<td align="right">
<input type="button" value="Add New Line" onclick="javascript:mAddLine();">
<input type="hidden" name="txtNextLineNumber" value="1">
<input type="submit" value="Send Document"/>

after clicking on add new line button i m able to new row in my existing table.below is code for adding new row

function mAddLine()
var lLineNumber;
var objNewRow;
var objNewCell;

lLineNumber = document.all.item('txtNextLineNumber').value;
objNewRow = document.all.item('LinesTable').insertRow();
if(document.all.item('LinesTable').rows(document.a ll.item('LinesTable').rows.length - 2).className == 'listrow0')
objNewRow.className = 'listrow1';
objNewRow.className = 'listrow0';

objNewCell = objNewRow.insertCell();
objNewCell.insertAdjacentHTML('beforeEnd', '<div id="divDetailLookup' + lLineNumber + '"><input type="text" name="txtSuppliersProductCode' + lLineNumber + '" style="width:65%"><a href="javascript:mGetProductDetails(' + lLineNumber + ')"><img src="/images/View_icon.gif" border="0" alt="Fetch product details"/></a></div>');

objNewCell = objNewRow.insertCell();
objNewCell.insertAdjacentHTML('beforeEnd', '<input type="hidden" name="txtBuyersProductCode' + lLineNumber + '">');
objNewCell.insertAdjacentHTML('beforeEnd', '<input type="hidden" name="txtPackSize' + lLineNumber + '">');
objNewCell.insertAdjacentHTML('beforeEnd', '<input type="text" name="txtProductDescription' + lLineNumber + '" style="width:100%">');

objNewCell = objNewRow.insertCell();
objNewCell.insertAdjacentHTML('beforeEnd', '<input onClick="mDeleteRow(this.parentNode.parentNode.rowIndex);" type="Button" name="btnDelete' + lLineNumber + '" value="Delete">');

document.all.item('txtNextLineNumber').value = parseInt(document.all.item('txtNextLineNumber').value) + 1;

i have delete button for each created row.when delete button clicked then corresponding row would be deleted.code is here

function mDeleteRow(linenumber)

document.all.item('LinesTable').deleteRow(linenumb er);
var objTable = document.getElementById("LinesTable");
for (var i = linenumber; i < objTable.rows.length; i++)
var objRow = objTable.rows[i];
objRow.className = (objRow.className == "listrow0") ? "listrow1" : "listrow0";


now problem is how to do validation.my each row has 2 fields both are manadatory so user should filled it.if not then i want to show alert message product code in line 1 should completed
description in line 1 should completed.and each row has different values for there product code field.

any body please help me out.

hope it make some sense.this is my first post at this forum.

i have seen this thread

and said by u after deletion i reset the id of my control like this

for(var i=nLoopStartIndex;i< objTable.rows.length;i++)

objTable.rows[i].childNodes[0].childNodes[0].id = "divDetailLookup" +i;
objTable.rows[i].childNodes[0].childNodes[0].childNodes[0].id = "txtSuppliersProductCode"+i ;
objTable.rows[i].childNodes[1].childNodes[0].id = "txtBuyersProductCode"+i;
objTable.rows[i].childNodes[1].childNodes[1].id = "txtPackSize" +i;
objTable.rows[i].childNodes[1].childNodes[2].id = "txtProductDescription"+i ;

but problem is after deleting row when i check for duplicate data in product field.it still taking data of deleted row.

what i m missing??
