question about post/get

[q2005]

Hi, all

When I do as the following, it becomes a GET action to the the server. How
do I make it as a POST action? That means I don't want the string after "?"
show on URL bar and, to the server, it can follow POST function to get the
data passed in. Thank you very much!

window.open("../../Server.php?"+xs Value, "", zNONHTML_STYLE) ;

This is a GET request, yes, but only if javascript is available. Without
javascript it is nothing.
If you want to POST something, there is no around using a form. If the
reliance on javascript is not a problem (but it usually is), this form can
be built dynamically:
var f=document.crea teElement('form ');
document.body.a ppendChild(f);
f.action='../../Server.php';
f.method='post' ;
var i=document.crea teElement('inpu t');
f.appendChild(i );
i.type='hidden' ;
i.name='somenam e';
i.value=xsValue ;
f.submit();

Thanks, Ivo. It's so helpful. By the way, after summit, how do I delete the
form object? Thanks again!

You don't. The form is submitted, so the whole page is 'deleted' as the
server responds with a brand new page. Note that the example code provided
does not test for features before using them. Include
if(document.cre ateElement) {...} and stuff like that before using it in the
real world. Also, try to avoid relying on javascript. If you can do it with
an ordinary form, and it sounds like you can, then do.

Thanks a lot, Ivo.
How do I let it be opened in a separate window after submmit?

In standard HTML, you can add a target attribute to the form opening tag and
it will behave just like the target attribute of <a> tags:

<form action="..." method="..." target="_blank" >

Amazing, isn't it?
In Javascript, to get the same result, you could add this line to the code
we discussed earlier:

f.target='_blan k';

Hi, Ivo
I tried this script and found "i.type='hidden ';" won't work. I changed to
"i.type='text'; " , it works. But it will show on the original page.

I assume you mean with IE?

According to Microsoft, the type attribute "is read[-many]/write-once, but
only when an input element is created with the createElement method and
before it is added to the document."

To be safe, the appendChild (or similar, like insertBefore) should be the
very last operation with a dynamically-created element. Set all of the
properties, and only then should said element be added.
I changed to "i.type='text'; " , it works.

Actually, I doubt that. The assignment will still probably fail, but
because text is the default type, it appears as though it succeeded.

After put the appendChild() at the very last, there is no more error!
