jsp中一个表单form中有两个文本域<input tpye ="text" name="str">,<input tpye ="text" name="end">,文本域的中输入日期，格式为“2009-12-09 16:15”，怎么用javascript实现对文本域中日期时间的比较，form怎么实现调用javascprit？

<html>
<head>
<script type="text/javascript">
function change()
{
var pattern=/^ *(\d{4})-(\d{1,2})-(\d{1,2}) (\d{1,2}):(\d{1,2}) *$/;
var outcome1=pattern.exec(str.value);
var outcome2=pattern.exec(end.value);
if (outcome1 && outcome2)
{
var result = compare2(outcome1[1], outcome2[1]);
if (result == 0)
{
result = compare2(outcome1[2], outcome2[2]);
if (result == 0)
{
result = compare2(outcome1[3], outcome2[3]);
if (result == 0)
{
result = compare2(outcome1[4], outcome2[4]);
if (result == 0)
{
result = compare2(outcome1[5], outcome2[5]);
}
}
}
}

if (result == 0)
alert("same date");
else if (result < 0)
alert("str < end&quo
