Manually closing a port between content and extension

[Avishay]

I create a port between content and extension using
chrome.extension.connect. Is there a way to manually close it (trigger
the onDisconnet event)?

Thanks, Avishay.

i didnt see that port supports this function? are you sure it supports it?

Here's the implementation of chrome.extension.sendRequest (found by putting a breakpoint in an extension then typing 'chrome.extension.sendRequest' into the Console).  Note near the bottom that the sender waits for a response on a port then .disconnect()s the port. - Michael

function (targetId_opt, request, responseCallback_opt) { var targetId = extensionId; var responseCallback = null; var lastArg = arguments.length - 1; if (typeof(arguments[lastArg]) == "function") responseCallback = arguments[lastArg--]; request = arguments[lastArg--]; if (lastArg >= 0 && typeof(arguments[lastArg]) == "string") targetId = arguments[lastArg--]; if (lastArg != -1) throw new Error("Invalid arguments to sendRequest."); var port = chrome.extension.connect(targetId, {name: chromeHidden.kRequestChannel}); port.postMessage(request); port.onDisconnect.addListener(function() { // For onDisconnects, we only notify the callback if there was an error try { if (chrome.extension.lastError && responseCallback) responseCallback(); } finally { port = null; } }); port.onMessage.addListener(function(response) { try { if (responseCallback) responseCallback(response); } finally { port.disconnect(); port = null; } }); }
