URL not passing in anchor tag

Question

Passing a javascript variable using tag in iframe by attaching variable like this "+var+" but its not passing value to next page . is there any different way or any bug in my code please suggest.

here is my code.

    <script>
    var user = "user@user.com"; 
    </script>

 <iframe src="http://127.0.0.1/ve2/ve2/www/kitchen-sink/api/fm/df.php?user="+user+""></iframe>

Thanks in advance .

All your code is doing is defining a variable, include all relevant code — Patrick Evans, Mar 28 '18 at 11:21
@uttamsharma this is not how Javascript works. You have to change the src attribute of the iframe via javascript. See https://www.w3schools.com/jsref/met_element_setattribute.asp for more information on how to set attributes. — BRO_THOM, Mar 28 '18 at 11:22
That iframe part isn't in javascript `+user` there is meaningless — Patrick Evans, Mar 28 '18 at 11:23

You cannot execute javascript directly, it has to be executed from script tags OR via an event.

<iframe id="iframe"></iframe>
<script>
    var iframe = document.getElementById('iframe');
    var user = "user@user.com";
    iframe.setAttribute('src', "http://127.0.0.1/ve2/ve2/www/kitchen-sink/api/fm/df.php?user=" + user );
</script>

Thanks for you efforts but its still not working – uttam sharma Mar 28 '18 at 11:27
This example is working. How are you determining it's NOT working? – BRO_THOM Mar 28 '18 at 11:28
df.php file fetching the value from url and echo this value and its not printing anything. that mean its not working. – uttam sharma Mar 28 '18 at 11:31

Please look at [this answer on SO](https://stackoverflow.com/questions/11480763/how-to-get-parameters-from-a-url-string) to get the query parameters from a URL in PHP – Chirag Ravindra Mar 28 '18 at 11:34
@uttamsharma please provide us a `var_dump` or `print_r` of your `$_GET` variables (during the call). – BRO_THOM Mar 28 '18 at 11:36
when i simply send a value like this df.php?user="user" its working but when i send data using a variable its not display anything – uttam sharma Mar 28 '18 at 12:00
