here i want to pass ajax called value to the another script(widget script) in same file. i have successfully done ajax call and justgage widget on a single page. i can successfully print the data got from ajax call using php echo. instead showing the values using echo, i want to use that same value for justgage widget to show. here i am sharing my code. data.php file is here
<?php
$selm=1;

$res3 = mysqli_query($con ,"SELECT * FROM meterstatus where `mtr_no` LIKE '$selm' and did='kirti' order by srno desc limit 1");

Here i can easily show values in my data.php file with "span id" and "php echo" method. but i want to use that value in justgage widget to show. but i cant pass this ajax call data value to the another js(justgage). i have tried all method but its showing "undefined". Is there any solution regarding this?
