chrome.tabs.executescript example
Example: get script result chrome.tabs.executeScript
chrome.browserAction.onClicked.addListener(function(tab) {
console.log('Injecting content script(s)');
//On Firefox document.body.textContent is probably more appropriate
chrome.tabs.executeScript(tab.id,{
code: 'document.body.innerText;'
//If you had something somewhat more complex you can use an IIFE:
//code: '(function (){return document.body.innerText;})();'
//If your code was complex, you should store it in a
// separate .js file, which you inject with the file: property.
},receiveText);
});
//tabs.executeScript() returns the results of the executed script
// in an array of results, one entry per frame in which the script
// was injected.
function receiveText(resultsArray){
console.log(resultsArray[0]);
}
