Generating dynamic date using Javascript.

function getRandomMaxMaturityDate() {

var myDate = new Date();
myDate.setDate(myDate.getDate()* (Math.random()* 555));
var date = myDate.getDay();
var month = myDate.getMonth();
var year = myDate.getYear();

document.forms[0].maxMaturityDateString.value = (month + "/" + date + "/" + year);
}

Setting parent window textbox based on pop-up window table row selection

Requirement:
I am having a parent window with a textbox and an adjacent search button. On click of the search button, a pop-up window should open with a table with 5 columns populated with rows in it and a OK button. On click of one of those rows and clicking OK button the selected row’s second column value should come and site in the parent windows text box.

JSP Code of parent page:

<td class="rmt-readOnlyRowHead" align="left" valign="top">
<span>
<html:text name="RequestForm" property="bankName" size="20" styleClass="rmt-formTxt" />
</span>
<span>
<input type="button" class="secondaryButton" id="search" value="Search"
onclick="window.open('searchBankName.do','searchBankName','resizable=1,width=710,height=650,status=1,scrollbars=1');" />
</span>
</td>

JSP Code of pop-up window:

<table id="t32bot" cellpadding="0" cellspacing="0" width="100%" border="0" id="sync">
<tbody>
<logic:iterate id="row" name="BankForm" property="bankList">
<tr id="srch_r1" clickable="yes">
<td nowrap class="rmt-tableCellTxt" onClick="clicked('t32bot',this);"> <bean:write name="row" property='countryName'/>
</td>
<td nowrap class="rmt-tableCellTxt" onClick="clicked('t32bot',this);"> <bean:write name="row" property='bankName'/>
</td>
<td nowrap class="rmt-tableCellTxt" onClick="clicked('t32bot',this);"> <bean:write name="row" property='facilityType'/>
</td>
</tr>
</logic:iterate>
</tbody>
</table>

<input type="button" class="primaryButton" id="ok" onClick="setBankName('t32bot');" value="Ok"/>

JS Code of pop-up window:

function setBankName(TABLE_NAME)
{
var bankName = window.opener.document.getElementById("bankName");
var tbl = document.getElementById(TABLE_NAME);

for (var i=0; i<tbl.tBodies[0].rows.length; i++) {
if (tbl.tBodies[0].rows[i].className.indexOf("rmt-rowClick") != -1) {
var rowElem = tbl.tBodies[0].rows[i];
var cell = rowElem.getElementsByTagName("td")[1];
bankName.value = cell.childNodes[0].data;
window.close();
}
}
}

JS code to select multiple rows from a table

JSP Page

<table id="t20bot" class="grid" width="100%">
<td width="60" onClick="clicked('t20bot',this);" ><bean:write name="row" property='countryName'/></td>

JS Function

function commonClicked(table_name, elem)
{
var rowElem = elem.parentNode;
if(rowElem.className == "rmt-rowClick" )
{
rowElem.className = "";
rowElem.oldClassName = "";
}
else
{
rowElem.className = "rmt-rowClick";
rowElem.oldClassName ="rmt-rowClick";
}
}
