Google Chrome Extension: captureVisibleTab problem
I'm trying to capture the current visible tab but I'm receiving undefined. The following code is executing when the extension's icon is pressed. When the alert is called I see undefined instead of an URL.
chrome.browserAction.onClicked.addListener(function(tab) {
chrome.windows.getCurrent(function (win) {
chrome.tabs.captureVisibleTab(win.id,{"format":"png"}, function(imgUrl) {
alert(imgUrl);
});
});
});
What should I do t开发者_如何学编程o get the URL of the captured image? Can someone please help me out with this.
Thanks!
I guess your code is taken from the example given on the Chrome Extension Website and yes, it's buggy.
Change the permission attribute inside the manifest.json to this:
"permissions": [
"tabs"
,"<all_urls>"
]

I tried your code and it did not return undefined for me. The following is the code.
Manifest.json
{
"name": "Test",
"version": "1.0",
"background_page": "background.html",
"browser_action": {
"default_icon": "icon.png"
},
"permissions": [
"tabs"
]
}
Background.html
<html>
<head>
<script>
chrome.browserAction.onClicked.addListener(function(tab) {
chrome.windows.getCurrent(function (win) {
chrome.tabs.captureVisibleTab(win.id,{"format":"png"}, function(imgUrl) {
alert(imgUrl);
});
});
});
</script>
</head>
</html>
加载中,请稍侯......
