javascript - AngularJS div background color with ngStyle -


one of div s observing background color variable ngstyle. anytime change the value, error. please see below, think more or less consistent example https://docs.angularjs.org/api/ng/directive/ngstyle

<div class="item item-divider" ng-style="scorecolor"><b>rate</b>&nbsp;{{score}}</div> <input type="range" name="rate" min="1" max="10" value="5" step="1" ng-model="score" ng-change="changescorecolor(score)"/>   $scope.changescorecolor = function(score){     $scope.scorecolor = "{background-color:" + colorfromscore(score) + ";}"; };    typeerror: name.replace not function     @ camelcase (http://localhost:8100/lib/ionic/js/ionic.bundle.js:11098:5)     @ foreach.css (http://localhost:8100/lib/ionic/js/ionic.bundle.js:11541:12)     @ object.jqlite.(anonymous function) [as css] (http://localhost:8100/lib/ionic/js/ionic.bundle.js:11667:9)     @ http://localhost:8100/lib/ionic/js/ionic.bundle.js:33610:57     @ foreach (http://localhost:8100/lib/ionic/js/ionic.bundle.js:9022:20)     @ ngstylewatchaction (http://localhost:8100/lib/ionic/js/ionic.bundle.js:33610:7)     @ object.$watchcollectionaction [as fn] (http://localhost:8100/lib/ionic/js/ionic.bundle.js:22809:13)     @ scope.$digest (http://localhost:8100/lib/ionic/js/ionic.bundle.js:22942:29)     @ scope.$apply (http://localhost:8100/lib/ionic/js/ionic.bundle.js:23205:24)     @ $$debounceviewvaluecommit (http://localhost:8100/lib/ionic/js/ionic.bundle.js:31961:14)

the ng-style expects object styles i.e.:

$scope.changescorecolor = function(score){     $scope.scorecolor = {'background-color': colorfromscore(score) }; };

you're passing string instead of object hence error.

here's documentation says expected ng-style argument:

expression evals object keys css style names , values corresponding values css keys.

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
