How can I concatenate a value inside function in jquery in this situation?

问题

I want to concatenate a value inside function in jquery. See code below. I want to put value data 1 into a function. Do you have any way to achieve what I want? Appreciate.

     var data='1';
	var user='<?php echo bp_core_get_user_domain('+ data +');?>';
				
         $("#find_members").html(user);

回答1:

Make an empty php page.

file.php

Inside put the PHP you want to interact with the JS value.

<?php 
function bp_core_get_user_domain($something) {
     //do Stuff here
      return $something;
}
echo bp_core_get_user_domain($_POST['data_var']);
?>

Then on your page make an ajax request to this script and the data will come back...

var data='1';
$.post( "file.php", { data_var: data})
  .done(function( data ) {
    $("#find_members").html(data);
  });

This is a rough version (untested), there are MANY examples out there for this.
