I am trying to create a simple safari extension. My current version of Safari is 5.1.7 running in Snow Leopard.
I have 2 documents :
global.html
<!DOCTYPE HTML>
<script>
safari.application.addEventListener("command", performCommand, false);
function performCommand(event) {
if (event.command === "traducir") {
var query = event.userInfo;
alert(query);
query = query.replace(/\s+/g,"+");
var newTab = safari.application.activeBrowserWindow.openTab();
newTab.url = "http://translate.google.es/#en/es/" + query ;
}
}
</script>
and the injected script : injected.js
document.addEventListener("contextmenu", handleMessage, false);
function handleMessage(msgEvent) {
var sel = '';
sel = window.parent.getSelection()+'';
sel = sel.replace(/^\s+|\s+$/g,"");
safari.self.tab.setContextMenuEventUserInfo(msgEvent, sel);
}
The extension is very simple :
1- When the user selects one text or word, click right-button and select the item of the contextual menu that raise the function.
2- The injected file gets the value of the selected text and it shared with the global.html through the userInfo.
3- The global.html script open a new tab with the url of google translate.
The problem is that event.userInfo is always NULL. I was searching in Google and all the examples are like this and I don´t know where the problem is and why it returns always NULL.
