Variable scope problem in JavaScript
- by dfjhdfjhdf
I declare a variable with the var word inside a function that handles Ajax requests, then later on in the function I have another function that should change the value of the variable but - my problem - it fails. How to settle the problem down? Here's similiar code I use:
function sendRuest(someargums) {
/* some code */
var the_variable;
/* some code */
//here's that other function
request.onreadystatechange =
function() {
if (request.readyState == 4) {
switch (request.status) {
case 200:
//here the variable should be changed
the_variable = request.responseXML;
/* a lot of code */
//somewhere here the function closes
}
return the_variable;
}
var data = sendRequest(someargums); //and trying to read the data I get the undefined value
