javascript - pageAction onClick no respond -


i added click event listener in working sample app (pageaction) have no idea has gone wrong. take @ 2 of file:

my manifest json

{   "name" : "page action content",   "version" : "1.1",   "description" : "shows page action html pages containing video",   "background" : {     "scripts": ["background.js"],     "persistent": false   },   "page_action" :   {     "default_icon" : "video-19.png",     "default_title" : "there's <video> in page!"   },   "permissions": [ "declarativecontent" ],   "icons" : {     "48" : "video-48.png",     "128" : "video-128.png"   },   "manifest_version": 2 }

background js

chrome.runtime.oninstalled.addlistener(function() {   chrome.declarativecontent.onpagechanged.removerules(undefined, function() {     chrome.declarativecontent.onpagechanged.addrules([{       conditions: [         // when page contains <video> tag...         new chrome.declarativecontent.pagestatematcher({           css: ["video"]         })       ],       // ... show page action.       actions: [new chrome.declarativecontent.showpageaction() ]     }]);   });  });    chrome.pageaction.onclicked.addlistener(function(tab) {   console.log('turning ' + tab.url + ' red!');   chrome.tabs.executescript({     code: 'document.body.style.backgroundcolor="red"'   }); });

i put click function within chrome.runtime, nothing happen. don't think forgot reload extension pack.

seems cannot access content of active tab, hence chrome.tabs.executescript failed.

try acquire "activetab" permission in addition.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
