Mixing javascript, jQuery and PHP, newline -

-

ok, have few things here:

javascript:

desc = "line 1 \n line 2"

jquery:

$("#msg").text(desc);

php:

const num = 555;

what want, change text of <p> id of msg, contain piece of text number of lines, , in 1 of them number php constant.

like so:

line 1
line 2 555, line 2 continued
line 3

my problem how mix them all? tried following:

var desc = "line 1 \n line2" + <?php echo num ?> +"\n line 3"; , doesn't work.

there several issues code:

  • php constants should defined using define("constant_name", "value"); syntax;
  • \n has no effect inside html tag (if dont apply white-space: pre; or pre-wrap);
  • <?php echo num; ?> should wrapped " or should inside javascript string;
  • $("#msg").text(desc) remove tags desc, need use .html(desc) instead.

what need this:

php

define("num", 555);

javascript

var desc = "line 1<br/>line2 <?php echo num; ?><br/>line 3"; $("#msg").html(desc);
