Chrome.tabs.executescript - Tabs Are Not Defined
Solution 1:
the error of "tabs are not defined"
tabs[0] - you need to find it. Your script is executed in the context of popup.html. I hope popup.html contain
<head>
...
<scriptsrc="popup.js"></script></head>and
Script of the button in chrome extension window
is from popup.js. And you never try to run code inside popup.html.
So, in this context no one knows about tabs[0]. You need to ask chrome which window and which tab is active now. It can be as ShwetaM wrote, or like this from samples
chrome.windows.getCurrent(function (currentWindow) {
chrome.tabs.query({ active: true, windowId: currentWindow.id }, function (activeTabs) {
activeTabs.map(function (tab) {
chrome.tabs.executeScript(tab.id, { file: 'content_script.js', allFrames: false });
});
});
});
or you can try without the tab.id,
chrome.tabs.executeScript({file:'content_script.js',allFrames:false});because in this case the script will run in the active tab of the current window
When you specify in Manifest.json the "content_scripts": script will be executed when you create a tab and every refresh. I'm not sure, but maybe before loading the DOM. However, you should not specify the "content_scripts": in Manifest.json, because this content script's code will be always injected
Also you must be sure that the active tab contains a button that you are looking for. Use console.dir for some object, especially arguments in a function; console.log for some text; debugger for happy debugging.
Solution 2:
you can just remove the parameter "tabs[0]"
integer(optional) tabId The ID of the tab in which to run the script; defaults to the active tab of the current window.

Solution 3:
Try this:
sendInMail = function(){
chrome.tabs.query({
active: true,
currentWindow: true
}, function(tabs) {
chrome.tabs.executeScript(tabs[0], {file: "content_script.js"});
});
}
