Update textarea From User Input by jQuery and Ajax - php

Question

I am trying to update a value in my php file and present it in a textarea using jquery and ajax. to make it short, I have:
1- A Form with User Input and Submit button and a Text area
2- A PHP file called data.php
3 -and the html file
Here is my codes
<form>
<input type="text" name="name"><br>
<textarea name="wstxt" id="wstxt" cols="40" rows="5"></textarea>
<input type="button" name="txta-update" id="txta-update" value="Update Textarea" />
</form>
PHP is as simple as:
<?php
$name = "Jordano";
echo $name;
and here is the jquery
$(document).ready(function() {
$('#txta-update').click(function() {
$.ajax({
type: "GET",
url: "data.php",//get response from this file
success: function(response){
$("textarea#wstxt").val(response);//send response to textarea
}
});
});
});
can you please tell me how I can send the input value to php and update the textarea from new value?
Thanks

Answer 1

Send data like this
data:{name:$('input[name="name"]').val()}
you js file becomes
$.ajax({
type: "GET",
url: "data.php", //get response from this file
data:{name:$('input[name="name"]').val()},
success: function (response) {
$("textarea#wstxt").val(response); //send response to textarea
}
});
or
$(document).ready(function () {
$('#txta-update').click(function () {
var name_val = $('input[name="name"]').val();
$.ajax({
type: "GET",
url: "data.php", //get response from this file
data: {
name: name_val
},
success: function (response) {
$("textarea#wstxt").val(response); //send response to textarea
}
});
});
});
To get value in PHP
<?php
$name = $_GET['name'];
echo $name;
?>
