How to use $_post with js??

At the moment i am using this js function

function saveData() {
	//store title and descr
	dataTitle = 'routeTitle=' + document.getElementById("dataTitle").value;
	dataDescr = document.getElementById("dataDescr").value;
userID = 'userID='+ document.getElementById("userID").value;
	window.location.href = "save-data.php?dataTitle+"&"+userID+"&dataDescr="+dataDescr;
}

Code (markup):

but i would like to use $_post in save-data.php. How should i rewrite function saveData()?

regards

 

Look at the example on this page: http://www.w3schools.com/php/php_post.asp

 

you need to encode that string as a url with something like

var thePost = 'key=' + encodeURI( 'value' ) + '&whatever=' + encodeURI( 'wherever' ) ;

however, I would use ajax to post the form and serialize() [ prototype ] to make the string instead of messing about, get prototype and look through the api docs on the site......

otherwise change $_POST to $_GET or $_REQUEST to have the script use post or get data

 

hmm, ok

I am asking how to do $_POST in a javascript function.

The $_GET/$_REQUEST way seems to work in firefox. I thought $_GET was restricted to 250 chars???/
