var date1 = document.form1.textfield5.value;
var month = parseInt(date1 [1]);
第二行没有意义. date1是日期字符串值.您如何将其假定为数组，并如何使用索引从中获取月，日或年.如果要使用此数组，请首先使用分隔符将date1拆分为数组.
试试:
var date1= document.form1.textfield5.value;
var month = parseInt(date1[1]);
Second line does not make sense. date1 is a date string value. How are you assuming it as an array and using an index to get month,date or year from it. If you want to use this array thing then split the date1 into an array first using their separator.
Try:
var dateBroken = date1.split("/");
//Now use this
// assuming it was mm/dd/yyyy
var month = dateBroken[0];
var day = dateBroken[1];
var year = dateBroken[2];sandeep@ thanks buddy , but even after changing the code to
