javascript - Inject content script on extension reload programmatically (chrome extension) -


i creating chrome extension want able enable/disable. have made popup that. trouble is, if reload extension (or if user downloads initially) content scripts default being off. could inject content script in manifest.json results in content script being injected new tab--which not want. behavior should if download/reload extension, on default, can enable it/disable , applies every new tab. have tried put initialization in background.js not called @ startup apparently.

manifest.json

{   "manifest_version": 2,   "name": "rotten tomatoes search",   "description": "this extension searches rotten tomatoes highlighted text",   "version": "1.0",   "browser_action": {     "default_icon": "./icons/icon_on.png",     "default_popup": "popup.html"   },   "permissions": [       "activetab",       "<all_urls>",       "background"   ],    "background": {     "scripts": ["background.js"],     "persistent": true   },   "content_scripts": [{      "js": ["jquery-1.12.3.min.js"],       "matches": ["<all_urls>"]    }] }

background.js

var isextensionon = true; chrome.tabs.executescript({code: "console.log('backgournd hit...')"});  turniton();  chrome.extension.onmessage.addlistener( function (request, sender, sendresponse) {     if (request.cmd == "setonoffstate") {         isextensionon = request.data.value;     }      if (request.cmd == "getonoffstate") {         sendresponse(isextensionon);     } });  function turniton() {     chrome.browseraction.seticon({path: "./icons/icon_on.png"});     chrome.tabs.executescript({file:"opentooltipmenu.js"});     //$('#toggle').text('disable'); }

popup.js

document.addeventlistener('domcontentloaded', function() { // show different text depending on on/off state (for icon, handled having default icon)  chrome.extension.sendmessage({ cmd: "getonoffstate" }, function(currentstate){     if (currentstate) $('#toggle').text('disable');     else $('#toggle').text('enable');  }); // allow user toggle state of extension var toggle = document.getelementbyid('toggle') toggle.addeventlistener('click', function() {     //chrome.tabs.executescript({code: "console.log('toggled...')"});     chrome.extension.sendmessage({ cmd: "getonoffstate" }, function(currentstate){         var newstate = !currentstate;         // toggle new state in background         chrome.extension.sendmessage({ cmd: "setonoffstate", data: { value: newstate } }, function(){             // after toggling, stuff based on new state             if (newstate) turnon();             else turnoff();         });     }); }) });  function turnon() {     chrome.browseraction.seticon({path: "./icons/icon_on.png"});     chrome.tabs.executescript({file:"opentooltipmenu.js"});     $('#toggle').text('disable'); }  function turnoff() {     chrome.browseraction.seticon({path: "./icons/icon_off.png"});     chrome.tabs.executescript({code: "$('body').off();"});     $('#toggle').text('enable'); }

popup.html

<some code>     <script src="./jquery-1.12.3.min.js"></script>     <script src="./popup.js"></script><style type="text/css"></style>   </head>   <body>     <div class="popupmenu" style="list-style-type:none">       <div class="header">rotten tomatoes search</div>       <hr>       <div class="menuentry" id="toggle"></div>     </div>   </body> </html>

i have figured out issue. architectural approach wrong. 1 should inject content_script globally check script whether or not should done. clearer, in script status background page , based on that. previously, injecting script once popup loaded or once when background initialized. additionally, 1 must loop through tabs in windows update state in tabs (if that's 1 wants).

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
