来自Angular翻译文档：
$translate(translationId [,interpolateParams],interpolationId);
interpolationId参数的用途是什么,你能举个例子吗？
What is the purpose of interpolationId parameter…
interpolationId的目的是引用已添加的自定义插值的getInterpolationIdentifier返回的标识符.您可以使用$translateProvider.addInterpolation添加自定义插值.
这在angular-translate的Pluralization documentation中有更好的记录.
…can you also give an example?
这是一个例子：

HTML
<body ng-controller="MyCtrl">
$translate('greeting',{},'custom'): {{ customGreeting }}
<br> $translate('greeting',{}): {{ regularGreeting }}
</body>
JavaScript的
var app = angular.module('app',[
'pascalprecht.translate'
]);
app.config(["$translateProvider",function($translateProvider){
$translateProvider.translations('en',{
"greeting" : "Welcome Dinesh"
});
$translateProvider.preferredLanguage('en');
$translateProvider.addInterpolation('customInterpolator');
}
]);
app.controller('MyCtrl',[
'$scope','$translate',function ($scope,$translate) {
$translate('greeting','custom').then(function (result) {
$scope.customGreeting = result;
});
$translate('greeting',{}).then(function (result) {
$scope.regularGreeting = result;
});
}
]);
app.factory('customInterpolator',[
function () {
var customInterpolator = {};
customInterpolator.$get = function () {
};
customInterpolator.setLocale = function (locale) {
};
customInterpolator.getInterpolationIdentifier = function () {
return 'custom';
};
customInterpolator.interpolate = function (string,interpolateParams) {
return 'My custom interpolation message';
};
return customInterpolator;
}
]);
