Re: Custom visual open new report

I am able to display hyperlink with this code:

'<a onclick=parent.postMessage("childframe","*");> '+ click here +' </a>'

But when i click on 'click here' it doesn't transfer the message even if the event is reached

window.addEventListener("message", function (event) {
   console.log(event.data); //display data but not the parameter
});

Update

With this 

'<a onclick=window.postMessage("childframe","*");> '+ task.typeDate.type+' </a>'

And this code :

// Create IE + others compatible event handler
var eventMethod = window.addEventListener ? "addEventListener" : "attachEvent";
var eventer = window[eventMethod];
var messageEvent = eventMethod == "attachEvent" ? "onmessage" : "message";

// Listen to message from child window
eventer(messageEvent, function (e) {
    console.log('parent received message!:  ', e.data);
}, false);

I can see my parameter but the origin source is unknwon so it is not safe at all
