The difference between get and post in jquery

Jquery-ajax get () and post () methods

The JQuery get () and post () methods are used to request data from the server through an HTTP get or POST request. HTTP Request: Get vs. POST

Two common ways to request-respond on both the client and server side are: Get and POST. Get-Request data POST from the specified resource-submits the data to be processed to the specified resource

Get is basically used to obtain (retrieve) data from the server. Note: The Get method may return cached data.

POST can also be used to get data from the server. However, the POST method does not cache data and is often used to send data along with the request.

To learn more about get and POST and the difference between the two methods, read our HTTP method-get comparison POST. jQuery $.get () method

The $.get () method requests data from the server through an HTTP GET request. Syntax: $.get (URL, callback);

The required URL parameters specify the URL you want to request.

The optional callback parameter is the name of the function that was executed after the request was successful.

The following example uses the $.get () method to retrieve data from a file on the server: instance $ ("button"). Click (function () {
$.get ("demo_test.php", function (data,status) {
Alert ("Data:" + Data + "Nstatus:" + status);
});
});
Try»

The first parameter of $.get () is the URL ("demo_test.php") that we want to request.

The second parameter is the callback function. The first callback parameter holds the content of the requested page, and the second callback parameter holds the state of the request.

Hint: this PHP file ("demo_test.php") looks like this: <?php
echo "This is some text from a external PHP file."
?>
jQuery $.post () method

The $.post () method requests data from the server via an HTTP POST request.

Grammar: $.post (Url,data,callback);

The required URL parameters specify the URL you want to request.

The optional data parameter provides the information to be sent along with the request.

The optional callback parameter is the name of the function that was executed after the request was successful.

The following example uses $.post () to send the data along with the request: instance $ ("button"). Click (function () {
$.post ("demo_test_post.html",
{
Name: "Donald Duck",
City: "Duckburg"
},
function (data,status) {
Alert ("Data:" + Data + "Nstatus:" + status);
});
});
Try»

The first parameter of $.post () is the URL ("demo_test_post.php") that we want to request.

Then we send the data along with the request (name and city).

The php script in "demo_test_post.php" reads these parameters, processes them, and then returns the results.

The third parameter is the callback function. The first callback parameter holds the content of the requested page, while the second parameter holds the state of the request.

Hint: this PHP file ("demo_test_post.php") looks like this: <?php
$name = isset ($_post[' name ')? Htmlspecialchars ($_post[' name ')]: ';
$city = isset ($_post[' city '))? Htmlspecialchars ($_post[' city ']): ';
Echo ' Dear '. $name;
Echo ' Hope you live-in '. $city;
?>
