1. IE不能渲染指令中的 style="background-color"，而chrome和firefox可以
<!DOCTYPE html>
<html ng-app="Dialog">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title>directive-dialog</title>
<meta content="IE=edge,chrome=1" http-equiv="X-UA-Compatible">
<script src="scripts/angular.js"></script>
</head>
<body>
<div ng-controller="MyCtrl">
<div>
<input type="text" ng-model="color" placeholder="Enter a color"/>
<hello-world color="{{color}}"/>
</div>
</div>
<script type="text/javascript">
var myModule = angular.module("Dialog", []);
myModule.controller("MyCtrl", function ($scope) {
$scope.color="blue";
});
myModule.directive('helloWorld', function factory() {
return {
scope: true,
restrict: 'E',
transclude:true,
replace:true,
template: '<p style="background-color:{{color}}">Hello World</p>' //
//
//解决办法：使用 ng-attr-style 来替换 style，这样IE就可以正常显示背景颜色
};
});
</script>
</body>
</html>
