先看看以下的代码
<body ng-app="app" ng-controller="ctrl">
<dir myname="name"></dir>
<script src="js/angular.js"></script>
<script>
var app = angular.module("app", []);
app.controller("ctrl", function ($scope, $timeout) {
$scope.name = "ABC";
$timeout(function () {
$scope.name = "XYZ";
//console.log("ctrl :" + $scope.name);
}, 2000);
});
app.directive("dir", function ($timeout) {
return {
restrict: "E",
template: "<div>{{dirName}}</div>",
link: function (scope, elem, attr) {
$timeout(function () {
//scope.name = "XYZ";
console.log("dir :" + scope.dirName);
}, 3000);
},
scope: {
dirName: "=myname"
}
}
});
</script>
</body>
以上 ^ : 一开始会显示ABC，2秒后会显示XYZ。*外面可以同步内部
app.controller("ctrl", function ($scope, $timeout) {
$scope.name = "ABC";
$timeout(function () {
//$scope.name = "XYZ";
//console.log("ctrl :" + $scope.name);
}, 2000);
});
app.directive("dir", function ($timeout) {
return {
restrict: "E",
template: "<div>{{dirName}}</div>",
link: function (scope, elem, attr) {
$timeout(function () {
scope.dirName = "XYZ";
console.log("dir :" + scope.dirName);
}, 3000);
},
scope: {
dirName: "=myname"
}
}
});
以上^ : 开始显示ABC，3秒后显示XYZ。*内部可以同步外部
app.controller("ctrl", function ($scope, $timeout) {
$scope.name = "ABC";
$timeout(function () {
$scope.name = "XYZ";
//console.log("ctrl :" + $scope.name);
}, 2000);
});
app.directive("dir", function ($timeout) {
return {
restrict: "E",
template: "<div>{{dirName}}</div>",
link: function (scope, elem, attr) {
$timeout(function () {
//scope.dirName = "XYZ";
console.log("dir :" + scope.dirName);
}, 3000);
},
scope: {
dirName: "@myname"
}
}
});
以上^ : 开始显示name，3秒后显示name。*内部的符号“@”只能拿到string
<body ng-app="app" ng-controller="ctrl">
<dir myname="{{name}}"></dir>
<script src="js/angular.js"></script>
<script>
var app = angular.module("app", []);
app.controller("ctrl", function ($scope, $timeout) {
$scope.name = "ABC";
$timeout(function () {
$scope.name = "XYZ";
//console.log("ctrl :" + $scope.name);
}, 2000);
});
app.directive("dir", function ($timeout) {
return {
restrict: "E",
template: "<div>{{dirName}}</div>",
link: function (scope, elem, attr) {
$timeout(function () {
//scope.dirName = "XYZ";
console.log("dir :" + scope.dirName);
}, 3000);
},
scope: {
dirName: "@myname"
}
}
});
</script>
</body>
以上 ^ : 一开始会显示ABC，2秒后会显示XYZ。*外面可以同步内部，同时注意div里是使用{{}}的表达式
app.controller("ctrl", function ($scope, $timeout) {
$scope.name = "ABC";
$timeout(function () {
//$scope.name = "XYZ";
//console.log("ctrl :" + $scope.name);
}, 2000);
});
app.directive("dir", function ($timeout) {
return {
restrict: "E",
template: "<div>{{dirName}}</div>",
link: function (scope, elem, attr) {
$timeout(function () {
scope.dirName = "XYZ";
console.log("dir :" + scope.dirName);
}, 3000);
},
scope: {
dirName: "@myname"
}
}
});
以上 ^ : 一开始会显示ABC，2秒后会显示XYZ。*内面可以同步外部，同时注意div里是使用{{}}的表达式
