how to store value from html textbox to javascript variable

[mmuk]

I am creating a form which fetches the value from the database and stores the value dynamically into a table. I have a button named add which adds a row dynamically when a user press it and I have a hidden counter which counts the rows added.The problem is, when I fetch the record, the counter shows the number of rows present and when I add a new row it goes back to 1.If there are two rows in the table, the counter will show 2 but when I try to add a new row the counter shows 1.Is there any way to set the value from the counter text into the JavaScript variable and increment it?Here is my JavaScript code:\[code\]<script language="javascript" type="text/javascript"> var jj= 1; alert(jj); function addRow() { //alert(jj) var tbl = document.getElementById('zimtable'); var lastRow = tbl.rows.length; var iteration = lastRow - 1; var row = tbl.insertRow(lastRow); var firstCell = row.insertCell(0); var el = document.createElement('input'); el.type = 'text'; el.name = 'zimname_' + jj; el.id = 'zimname_' + jj; el.size = 40; el.maxlength = 40; firstCell.appendChild(el); var secondCell = row.insertCell(1); var el2 = document.createElement('input'); el2.type = 'text'; el2.name = 'zimmob_' + jj; el2.id = 'zimmob_' + jj; el2.size = 13; el2.maxlength = 13; secondCell.appendChild(el2); // alert(i); //$('#hh').val(jj); jj++; makhtab.hh.value=http://stackoverflow.com/questions/14602945/jj; alert(jj); }</script>\[/code\]Here is my php code to show the table:\[code\]<?php $zim = mysql_query("SELECT * FROM `makhzim` WHERE makhcode='$newsid' ORDER BY srno")or die(mysl_error()); $ctrzim = 0; while ($zrow = mysql_fetch_array($zim)){ $ctrzim++; print '<script type="text/javascript">'; print "alert('$i')"; print '</script>'; echo "<tr>"; echo "<td><input name='zimname_$ctrzim' type='text' size='40' maxlength='20' value=http://stackoverflow.com/questions/14602945/$zrow[name] /></td>"; echo "<td><input name='zimmob_$ctrzim' type='text' size='13' maxlength='20' value=http://stackoverflow.com/questions/14602945/$zrow[mobile] /></td>"; echo "</tr>"; } echo "</table>"; echo "<input type=\"button\" value=http://stackoverflow.com/"Add\" onclick=\"addRow();\" /><input id=\"hh\" name=\"hh\" type=\"text\" value= 'http://stackoverflow.com/questions/14602945/$ctrzim'/>";?>\[/code\]
