我正在尝试将字符串变量从我的 Controller 传递到使用隔离范围的指令。我已经成功地传递了一个对象和一个函数，但似乎无法让它工作!
Controller :
angular.module("app").controller("myCtrl", function($scope)
{
//data that needs to be passed to the directive
$scope.myParams = $scope.params; //object
$scope.myDateOrder = $scope.dateOrder; //string
});
html:
<div ng-controller="myCtrl">
<my-dir params="myParams" dateOrder="myDateOrder">
</my-dir>
</div>
指令:
angular.module("app").directive("myDir", [
function() {
return {
restrict: "E",
scope: {
checkPermissions: "&", //pulled from contact directive -> method/function
params: "=", //passed object though from smwAddCustomerBank -> two way binding
dateOrder: "@" //passed string value from smwAddCustomerBank -> one way binding
},
日期订单不起作用。如果我在 Controller 中console.log它，我可以看到该字符串，如果我然后将其记录在我的指令中，它是未定义的。
有什么想法吗？
最佳答案
指令属性需要为kebab-case ，不是camelCase :
<div ng-controller="myCtrl">
̶<̶m̶y̶-̶d̶i̶r̶ ̶p̶a̶r̶a̶m̶s̶=̶"̶m̶y̶P̶a̶r̶a̶m̶s̶"̶ ̶d̶a̶t̶e̶O̶r̶d̶e̶r̶=̶"̶m̶y̶D̶a̶t̶e̶O̶r̶d̶e̶r̶"̶>̶ ̶
<my-dir params="myParams" date-order="myDateOrder">
</my-dir>
</div>

<小时/>Thank you - for anyone else that struggles with this, the full change I needed to make is:
params="myParams", date-order="{{ myDateOrder }}"
要避免使用插值 ( {{ }} )，请使用 "<" 的单向绑定(bind)而不是使用 "&" 进行属性绑定(bind) :
scope: {
checkPermissions: "&", //pulled from contact directive -> method/function
params: "=", //passed object though from smwAddCustomerBank -> two way binding
̶d̶a̶t̶e̶O̶r̶d̶e̶r̶:̶ ̶"̶@̶"̶
dateOrder: "<" //passed string value from smwAddCustomerBank -> one way binding
}
然后只需执行:
<my-dir params="myParams" date-order="myDateOrder">
