Tab Scroll Position

[Hemang Dhamani]

Hi,

Can anyone help me to get Tab's scroll position using chrome.tabs.executescript?

Please any sample code / web url would be good.

Thanks,

Hemang

I guess something like -

chrome.extension.onRequest.addListener(function (scrollTop) { alert("The scrollTop is " + scrollTop); });

chrome.tabs.executeScript({"code": "chrome.extension.sendRequest(document.body.scrollTop)"});

Hi,

Thanks for the code, but I am facing another problem with below code in background.js.

var ls = localStorage;

chrome.extension.onRequest.addListener(

function (req) {

var rtGroup = JSON.parse(ls.rtGroupInfo);

rtGroup.oWindows[parseInt(req.winId)].oTabs[parseInt(req.tabId)].scrRight = parseInt(req.scrollLeft);

rtGroup.oWindows[parseInt(req.winId)].oTabs[parseInt(req.tabId)].scrDown = parseInt(req.scrollTop);

ls.rtGroupInfo = JSON.stringify(rtGroup);

}

);

// Get Scroll Left and Scroll Top position

console.log(ls.rtGroupInfo);

if (ls.rtGroupInfo != undefined) {

var rtGroup = JSON.parse(ls.rtGroupInfo);

for (var i = 0; i < rtGroup.oWindows.length; i++) {

for (var j = 0; j < rtGroup.oWindows[i].oTabs.length; j++) {

chrome.tabs.executeScript(rtGroup.oWindows[i].oTabs[j].id, {"code": "chrome.extension.sendRequest({winId: " + i + ", tabId: " + j + ", scrollLeft: " + "document.body.scrollLeft" + ", scrollTop: " + "document.body.scrollTop})"});

}

}

}

In above code, when I put debug pointer on line "if (ls.rtGroupInfo != undefined)" ... I get proper value, otherwise it is "undefined". Any idea?

Thanks,

Hemang
