这是关于ng-init的角度文档。
ngInit指令允许您评估当前范围中的表达式。
但是，如果我将ng-init与自定义指令一起使用，并且该指令使用不同的范围，则<body ng-app="transcludeScope" ng-init="test='test'">
<div truescope ng-init="test2='test2'">Transcluded:<p>test: {{test}}</p><p>test2: {{test2}}</p><p>test3: {{test3}}</p></div>
<hr>
<div isolatescope ng-init="test3='test3'">Transcluded:<p>test: {{test}}</p><p>test2: {{test2}}</p><p>test3: {{test3}}</p></div>
</div>
</body>
angular.module('transcludeScope', [])
.directive('truescope', function() {
return {
transclude: true,
scope: true,
template: "<p>test: {{test}}</p><p>test2: {{test2}}</p><div ng-transclude></div>"
}
})
.directive('isolatescope', function() {
return {
transclude: true,
scope: {},
template: "<p>test: {{test}}</p><p>test3: {{test3}}</p><div ng-transclude></div>"
}
});
的变量将具有不同的范围。
test2从结果来看，test3仅在指令内可用，而 // Program uses wave data to calcuulate steepness and average steepness for the year

可用于整个应用。
任何人都可以解释他们的行为吗？谢谢： - ）
