  "content_scripts": [
    {
      "matches": ["http://www.google.com/*"],

popup.html

<html>

<body>

function getHTML()
{

chrome.tabs.getSelected(null, function(tab) {
    chrome.tabs.sendRequest(tab.id, {method: "getHTML"}, function(response) {
        if(respond.method="getHTML"){               
            alert(response.html);  
      }
    });
});

}
</script>
 <input type="submit" value="OK" onclick ="getHTML()" />
</body>

contentscript.js

chrome.extension.onRequest.addListener(
    function(request, sender, sendResponse) {
        if(request.method == "getHTML"){
            sendResponse({html: document.all[0].outerHTML});
        }
    }
);

Answer 1

I see two errors: 1) popup.html is checking for "respond" instead of "response". 2) popup.html is checking for response.method to be "getHTML", but the content_script never sets the "method" field.

Answer 2

document.all/code> is un Defin in Mitchell!



Replace it with document.getElementsByTagName("html")[0].innerHTML:

chrome.extension.onRequest.addListener(
    function(request, sender, sendResponse) {
        if(request.method == "getHTML"){
            sendResponse({html: document.getElementsByTagName("html")[0].innerHTML});
        }
    }
);
