I set some variables in serverside through PHP
$LGD_AMOUNT = ""; //Amount is for the price that customer purchases
$LGD_BUYER = "";//Buyer collect name of the customer
And I store these in $payReqMap
$payReqMap['LGD_AMOUNT'] = $LGD_AMOUNT;
$payReqMap['LGD_BUYER'] = $LGD_BUYER;
what I want to do is before I send these to the server side, in <script> part, I want to give them values. Is there any method that I can call these stored variables in <script> part?
This is a start point to use Ajax using pure Javascript;
function getxmlhttp (){
//Create a boolean variable to check for a valid Microsoft active x instance.
var xmlhttp = false;
//Check if we are using internet explorer.
try {
//If the javascript version is greater than 5.
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e) {
//If not, then use the older active x object.
try {
//If we are using internet explorer.
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
catch (E) {
//Else we must be using a non-internet explorer browser.
xmlhttp = false;
}
}
// If not using IE, create a
// JavaScript instance of the object.
if (!xmlhttp && typeof XMLHttpRequest != 'undefined') {
xmlhttp = new XMLHttpRequest();
}
return xmlhttp;
}//Function getxmlhttp()
//Function to process an XMLHttpRequest.
function processajax (serverPage, obj, getOrPost, str){
//Get an XMLHttpRequest object for use.
xmlhttp = getxmlhttp ();
if (getOrPost == "get"){
xmlhttp.open("GET", serverPage);
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
obj.innerHTML = xmlhttp.responseText;
}
}
xmlhttp.send(null);
}
else {
xmlhttp.open("POST", serverPage, true);
xmlhttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded; charset=UTF-8");
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
obj.innerHTML = xmlhttp.responseText;
}
}
xmlhttp.send(str);
}
}
