Snæ*_*ørn 9 translation angularjs angularjs-ng-click
我做了一个plunker演示(点击按钮,观察输入框保持不变)
标记:
<body ng-controller="Ctrl">
<input type="text" id="input" name="input" ng-model="myValue" test>
<p translate="VARIABLE_REPLACEMENT" translate-values="{{ 'translationData' }}"></p>
<p ng-bind-html="alink"></p>
</body>

角度的东西:
var translations = {
VARIABLE_REPLACEMENT: 'Hi, {{name}}'
};
var app = angular.module('myApp', ['pascalprecht.translate', 'ngSanitize']);
app.config(['$translateProvider', function ($translateProvider) {
// add translation table
$translateProvider.translations(translations);
}]);
app.controller('Ctrl', ['$scope', '$sce', function ($scope, $sce) {
$scope.translationData = { name: 'foo'};
$scope.setValue = function(value) {
$scope.myValue = value;
};
}]);
app.directive('test', ['$translate', '$sce', function ($translate, $sce) {
return {
require: 'ngModel',
scope: false,
link: function (scope, element, attrs, ctrl) {
scope.$watch(attrs.ngModel, function (value) {
var a = $translate('VARIABLE_REPLACEMENT', {
name: '<button type="button" ng-click="setValue(\'foobar\')">click me</button>'
});
scope.alink = $sce.trustAsHtml(a);
});
}
};
}]);

问题是:ng-click="setValue('foobar')"单击按钮时为什么不触发.它应该在输入字段中设置值'foobar'.

角没有$compile的$sce标记.所以Angular没有处理你ng-click的指令并将其附加到它.
为了在你的字符串中使用Angular指令并让它们生效,你需要将字符串发送给Angular的$compile函数.
一个简单的方法是使用以下指令(在这里找到:https://github.com/angular/angular.js/issues/4992)
使用这个你将替换:
<p ng-bind-html="alink"></p>

同
<p compile="alink"></p>

并添加此指令:
angularApp.directive('compile', function($compile) {
// directive factory creates a link function
return function(scope, element, attrs) {
scope.$watch(
function(scope) {
// watch the 'compile' expression for changes
return scope.$eval(attrs.compile);
},
function(value) {
// when the 'compile' expression changes
// assign it into the current DOM
element.html(value);
// compile the new DOM and link it to the current
// scope.
// NOTE: we only compile .childNodes so that
// we don't get into infinite loop compiling ourselves
$compile(element.contents())(scope);
}
);
};

与此同时,该问题有一个官方解决方案:
<p translate="varWithDirective" translate-compile></p>

会编译而不需要编写自定义指令.
