如何将JavaScript变量传递给PHP并加载PHP

Question

I have a requirement to pass the JavaScript object to a PHP file and load that PHP file in browser when a button is clicked.

index.html has the following code:

<button id="1a" type="button">Click here</button>

custom.js has the following code:

var testobject={'element1':1, 'element2':2}

$(document).ready(function() {

    $("#123456").click(function(event){
        $.post(
            "test.php",
            testobject
        );
    });

But I don't know to write a php file to receive this data. Also I am not able to understand how to load this PHP file.

Answer 1

You need to make sure your click event is actually tied to the button using the correct ID, so

$("#1a").click(...); 

in this case. Once you have that, clicking the button will cause a POST to happen to the PHP file, this is where it will load. You can then access those variables in the most simple way like:

<?php 
$element1 = $_POST["element1"];
$element2 = $_POST["element2"];
?>

as the other answer implies.
