Open page in the same window

Hi,

I need to open a new page in the same window when clicked on submit button. Below is my function code.

With window.open(), i can open the page in a new window.
I tried window.open("xxx.jsp",_self) and window.location.href = "xxx.jsp" but can't open the new xxx.jsp page.

can some one help me how to open it in the same page.

function check(form)
{
if(form.username.value == "" || form.password.value == "")
{
alert("xxxxx")
}
else if(form.username.value == "xxx" && form.password.value == "xxx")
{
window.open("xxx.jsp")
//window.location.href = "xxx.jsp"
}
else
{
alert("xxx")
}
}

You wouldn't use window.open() to submit the form to the same page; you would just submit the form values to your current page. Which if you write your server side code correctly... your server side code will get your form values; once the page is submitted to itself.
