这里我创建了自定义指令,用于显示和隐藏json数据中的特定字段,这里我的问题是角度版本,低版本工作(https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js),但高版本不支持({{3} })
请查看以下链接 https://code.angularjs.org/1.3.15/angular.js
var app = angular.module(' testApp',[]);
app.directive('telBasictext1', ['$http', 'telngshowservice', function($http, telngshowservice) {
return {
restrict: 'AEC',
require: 'ngModel',
scope: {
ngModel: '=',
placeHold: '@',
checkId: '@',
className: '@',
ngmaxLength: '@',
ngminLength: '@',
lblvalue: '@',
textboxSize: '@',
lblSize: '@',
validate: '@',
ngShow: '@',
textboxtype: '@',
getString: '@',
position: '@',
labelPosition: '@',
textboxPosition: '@',
canShow: '@',
showorhide: '@',
},
template: '<div id="{{ checkId }}" class="form-group" ng-show="true" > ' +
'<label size="lblSize" class="col-sm-{{ labelPosition }} control-label" id="textboxchanges"> Test </label>' +
'<div class="col-sm-{{ textboxPosition }}"> <input type="{{ textboxtype }}" ng-model="ngModel" placeholder="{{ placeHold }}" id="{{checkId}}" class="{{className}}" minlength="{{ ngminLength }}" maxlength="{{ ngmaxLength }}" size="{{ textboxSize }}" ng-required="{{ validate }}" ></div></div>',
link: function(scope, iElement, iAttrs, ngModelController) {
var ngshow = iAttrs.canShow;
var ngsplitValues = ngshow.split(",");
var nglanguage = ngsplitValues[0]; // Language EN or Fr
var nglabelName = ngsplitValues[1]; // Label Name
var ngmoduleName = ngsplitValues[2]; // Module Name (global or local)
telngshowservice.getdata(ngmoduleName).success(function(data) {
scope.showorhide = data[nglabelName];
console.log(scope.showorhide)
})
}
};
}]);
app.factory('telngshowservice', ['$http', function($http) {
var dataFactory = {};
var lang = window.localStorage.language;
dataFactory.getdata = function(moduleName) {
if (moduleName == 'common') {
return $http.get(labeli18nPath + '/translation_' + lang + '.json');
} else {
return $http.get('OPlayout.json');
}
};
return dataFactory;
}]);

这是因为版本 1.3.0-beta.14 中的$parse
服务发生了重大变化:
核心:由于bdfc9c02,值'f','0','false','no','n','[]'是 不再被视为麻痹。现在只有JavaScript假值 被表达式解析器视为falsy;其中有六个: false,null,undefined,NaN,0和“”。
使用布尔值代替字符串:
{
"pSearchPatient": false,
"pAddressNo" : true,
"pBuilding": true
}
