Chrome Extension Active Tab Selecting Problem
A short time, looking at the issue of Chrome Extension Development.
I开发者_开发问答 use jQuery and plugins. But not selecting DOM elements with jQuery.
example code here; (background.html)
<html>
<head>
<script>
function alertValue() {
var a = $("#divName").val();
alert(a);
}
chrome.browserAction.onClicked.addListener(alertValue);
</script>
</head>
</html>
As a result, returns undefined.
If I understood correctly you want to read a value of some element on a current page when a user clicks a browser action icon.
To do this you need to use a content script to actualy read the value on a page, and message passing to communicate between a background page and a content script.
