trying to learn .post method in jQuery - is there a way to pass a variable to the code to use in the 'data' argument of the function. The 'try it yourself' example from w3schools has the data hard-coded in, but I would like to use a variable that I got from a form, or something to do the post. I tried a few things but to no avail. Here is the code from the example: <!DOCTYPE html> <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <script> $(document).ready(function(){ $("button").click(function(){ $.post("demo_test_post.asp", { name: "Donald Duck", city: "Duckburg" }, function(data,status){ alert("Data: " + data + "\nStatus: " + status); }); }); }); </script> </head> <body> <button>Send an HTTP POST request to a page and get the result back</button> </body> </html> I tried this but it didn't work. I tried with and without the braces. How can you pass a variable to a jQuery method? should I use a global variable. please be explicit. Thanx <!DOCTYPE html> <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <script> $(document).ready(function(){ $("button").click(function(){ var myName = "Donald Duck"; var myCity = "Duckburg"; var myData = "{name:" + myName + ", city:" + myCity + "}"; $.post("demo_test_post.asp", myData, function(data,status){ alert("Data: " + data + "\nStatus: " + status); }); }); }); </script> </head> <body> <button>Send an HTTP POST request to a page and get the result back</button> </body> </html>
