如何使用AJAX GET传递php值

Question

I would like to send a php value with this function

$k = $_GET['k'];

function getData() {
    $.post('page.php', {
    action  : 'loader',
    number : $settings.nop,
    offset : offset,

    //I LIKE TO SEND $k
}

Answer 1

PHP is a server side language and JS is a client side language So this variable is not directly accessible in javascript which can be sent in an ajax request.

So from php side you can expose this variable $k using a global variable and then send it in the ajax call from Js like this

PHP

<script type="text/javascript">
  window.myGlobalVariable = "<?php echo $_GET['k'] ?>"
</script>

Now you can send it in JS like this.

JS

function getData() {
    $.post('page.php', {
    action  : 'loader',
    number : $settings.nop,
    offset : offset,
    variable : myGlobalVariable //Value of myGlobalVariable will be set by PHP code
}
