loop date problem

[robert_gsfame]

i have listbox which contain of day, month and year

 

Month should generate number of days, for example if i choose Feb then it will check whether leap year and generate days

 

for(i=1;i<parseInt(totaldays)+1;i++){

var totaldays="<option value='"+i+"'>"+i+"</option>";

var all=xyz+totaldays;

xyz=all;}

 

document.getElementById("myday").innerHTML="<select id=cday onchange=changethis() >"+all+"</select>";

 

 

Problem: all works well but when i choose 30 from day listbox, it will automatically return to 1.

 

which part is wrong? please give me a clue

thx

You'll need to list all relevant code. You're only showing us a little of it.

 

Also, PLEASE use the code tags.
