How to pass parameters through iframe from parent html?

I have a html page in which I am setting the src for an iframe programmatically. How can I pass parameters through the iframe src and get them in the child html?

Below my code:

<iframe id="myIframe" src="" height="250px"  width="100%" scrolling="yes" frameborder="0"></iframe>

function myFunction(){
$('#myIframe').attr('src', "myIframeRequest.html"); 
}

If you have slightly more control on your iframe sandbox, you can try postMessage API to communicate with message on events you desire to trigger.

On the main page simply pass parameters as follows

function myFunction(){
$('#myIframe').attr('src', "myIframeRequest.html?param1=value1&param2=value2"); 
}

In Iframe

You can use a script to get the desired parameter value from parameters passed to page.

<script>
function getParamValue(paramName)
{
    var url = window.location.search.substring(1); //get rid of "?" in querystring
    var qArray = url.split('&'); //get key-value pairs
    for (var i = 0; i < qArray.length; i++) 
    {
        var pArr = qArray[i].split('='); //split key and value
        if (pArr[0] == paramName) 
            return pArr[1]; //return value
    }
}
</script>

Then you can fetch the value of desired parameter like this

var param1 = getParamValue('param1');

you should make a serverside page like (myIframeRequest.php) php/jsp and get the parameter value in that page if it s an html page then parse the window.location.href through javascript and find the query/param
