can someone point me out how can I send JavaScript variables with AJAX.
JavaScript:
var d=new Date();
document.write(d);
AJAX:
$.ajax
({
type: 'POST',
url: 'save.php',
cache: false,
data: { document.write(d); // Just for example
},
Everything else works great. Thanks.
You can't send "variables". You can only send strings (or things which can be turned into strings). (You can store those strings in variables).
A date object (which you store in d) can be converted into a string, so you could send that.
The return value of document.write() will always be undefined, so it doesn't make much sense to send that.
You appear to be using jQuery. The data property expects a standard JavaScript object. An object consists of a bunch of key/value pairs. You need to provide a key for your value.
data: { date: d }
you could pass the value to any parameter name you want like date parameter in this example:
$.ajax({
type: 'POST',
url: 'save.php',
cache: false,
data: { date: new Date()}
});
Or you could just use the variable like this:
var d = new Date();
$.ajax({
type: 'POST',
url: 'save.php',
cache: false,
data: { date: d}
});
Use JSON.stringify() to convert your objects to JSON format:
$.ajax
({
type: 'POST',
url: 'save.php',
cache: false,
data: JSON.stringify(d)
},
On the server side, of course, you would have to use a JSON parser to interpret the data.
