getting a variable value in an html page and using it in an external js

hi have a php template that displays an html page. in it there is a call to a js file that initializes some jquery plugins.

on the template i have this code:

(function($) { 

 $(document).ready(function(){
     var adlow = <?php echo $jSeblod->disparities_tick_lower-&g开发者_StackOverflow社区t;value ?>;
     var adhigh = <?php echo $jSeblod->disparities_tick_upper->value ?>;
     var adtickno = <?php echo $jSeblod->disparities_tick_divisions->value ?>;

    });
})(jQuery);

then on the init.js page i call adlow, adhigh and adtickno. i get variable undefined errors.

the php is returning the correct values. but then the external init file is not getting them. do i need to do something special to get the init file to be able to use these variables? all i did was just plug them in...

thanks, i am a little hazy on the interaction between these pages.

They need to be globals for other pages to use them. Try removing the var. Or namespace them, which is better practice:

$(document).ready(function(){
    MYAPP = {};
    MYAPP.adlow = <?php echo $jSeblod->disparities_tick_lower->value ?>;
    MYAPP.adhigh = <?php echo $jSeblod->disparities_tick_upper->value ?>;
    MYAPP.adtickno = <?php echo $jSeblod->disparities_tick_divisions->value ?>;

   });

You need to print them in global scope before init.js get loaded.

<script>
    var adlow = <?php echo $jSeblod->disparities_tick_lower->value ?>;
    var adhigh = <?php echo $jSeblod->disparities_tick_upper->value ?>;
    var adtickno = <?php echo $jSeblod->disparities_tick_divisions->value ?>;
</script>
<script src="init.js"></script>

Printing them during $(document).ready() makes no sense. The init.js already get loaded before that.
