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);
}
On the main page simply pass parameters as follows
function myFunction(){
$('#myIframe').attr('src', myIframeRequest.html?param1=value1¶m2=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');
