如何使用angularjs指令数据绑定一个MVC局部视图 [英] How to data-bind an mvc partial view using angularjs directives
问题描述
我有以下angularjs指令:
app.directive(partnersInfoView功能($ HTTP){
返回{
限制:'A',
链接:功能($范围,元素){
$ http.get(/家/ PartnerInfoTab)//立即调用来检索部分
.success(功能(数据){
element.html(数据); //使用响应代替该元素的内心
});
}
};
});
这基本上进入一个MVC控制器,并返回一个局部视图
公众的ActionResult PartnerInfoTab()
{
返回PartialView(../ ManagePartners / PartnerInfoTab);
}
在我有以下声明父视图:
< DIV ID =genericControllerNG控制器=GenericController>
< DIV合作伙伴 - 信息 - 视图>< / DIV>
< / DIV>
这是利用角指令呈现局部视图,到目前为止一切都很正常。里面我的角度genericController我有一个范围的变量:
$ scope.Data =数据;
,其中数据是自带来自REST服务
响应JSON对象JSON响应例如
{[
{名字:约翰,姓氏:李四},
{名字:安娜,姓氏:史密斯},
{名字:彼得,姓氏:琼斯}
]}
遇到的问题IM的是,我不能在指令模板中的$ scope.Data绑定变量:
< DIV ID =PartnerInfoTab>
< DIV CLASS =表单组>
<标签类=COL-MD-2控制标签>名称和LT; /标签>
< DIV CLASS =COL-MD-8>
<输入ID =txt_name级=表格控型=文本NG模型=Data.firstName>
< / DIV>
< / DIV>
< / DIV>
我的问题是,你如何传递父范围的角度指令,以便能够数据绑定在局部视图中的元素。我在想什么?
先谢谢了。
我看不出有任何使用手动取模板使用 $ http.get
,然后将其插入的到DOM。你可以简单地给 templateUrl
指令中的配置值和角度将获取模板和编译它。
app.directive(partnersInfoView功能($ HTTP){
返回{
限制:'A',
templateUrl:'/家庭/ PartnerInfoTab',
链接:功能(范围,元素,属性){
//进行链接
}
};
});
和,你的 partnersInfoView
不产生孤立的范围。因此,您可以访问 partnersInfoView
的母公司范围值的值。看到下面的代码片段。
VAR应用= angular.module('应用',[]);\r
\r
app.run(函数($ templateCache){\r
//模拟/家庭/ PartnerInfoTab模板的取\r
VAR模板='< DIV ID =PartnerInfoTab>' +\r
'< DIV CLASS =表单组>' +\r
'<标签类=COL-MD-2控制标签>名称和LT; /标签> +\r
'< DIV CLASS =COL-MD-8>' +\r
'<输入ID =txt_name级=表格控型=文本NG模型=数据[0] .firstName>' +\r
'<输入ID =txt_name级=表格控型=文本NG模型=数据[1] .firstName>' +\r
'<输入ID =txt_name级=表格控型=文本NG模型=数据[2] .firstName>' +\r
'< / DIV>' +\r
'< / DIV>' +\r
'< / DIV>';\r
\r
$ templateCache.put('/家庭/ PartnerInfoTab',模板);\r
});\r
\r
app.controller('GenericController',函数($范围){\r
$ scope.Data = [{\r
名字:约翰,\r
姓氏:李四\r
},{\r
名字:安娜,\r
姓氏:史密斯\r
},{\r
名字:彼得,\r
姓氏:琼斯\r
}];\r
});\r
\r
app.directive(partnersInfoView功能($ HTTP){\r
返回{\r
限制:'A',\r
templateUrl:/家/ PartnerInfoTab\r
链接:功能($范围,元素){\r
//链接\r
}\r
};\r
\r
});
\r
&LT;脚本SRC =https://ajax.googleapis.com/ajax /libs/angularjs/1.2.23/angular.min.js\"></script>\r
&LT; DIV NG-应用=应用程序&GT;\r
&LT; DIV ID =genericControllerNG控制器=GenericController&GT;\r
&LT; DIV合作伙伴 - 信息 - 视图&gt;&LT; / DIV&GT;\r

I have the following angularjs directive:
app.directive("partnersInfoView", function ($http) {
return {
restrict: 'A',
link: function ($scope, element) {
$http.get("/home/PartnerInfoTab") // immediately call to retrieve partial
.success(function (data) {
element.html(data); // replace insides of this element with response
});
}
};
});
which basically goes to an MVC controller and returns a partial view
public ActionResult PartnerInfoTab()
{
return PartialView("../ManagePartners/PartnerInfoTab");
}
in the parent view i have the following declaration:
<div id="genericController" ng-controller="GenericController">
<div partners-info-view></div>
</div>
that is making use of the angular directive to render the partial view, so far everything works great. Inside of my angular genericController i have a scope variable:
$scope.Data = data;
where data it's a json object that comes as response from a Rest Service
Json Response e.g.
{[
{"firstName":"John", "lastName":"Doe"},
{"firstName":"Anna", "lastName":"Smith"},
{"firstName":"Peter", "lastName":"Jones"}
]}
The issue im having is that i cannot bind the $scope.Data variable in the directive template:
<div id="PartnerInfoTab">
<div class="form-group">
<label class="col-md-2 control-label">Name</label>
<div class="col-md-8">
<input id="txt_name" class="form-control" type="text" ng-model="Data.firstName">
</div>
</div>
</div>
My question is, How do you pass the parent scope to the angular directive in order to be able to data-bind the elements in the partial view. What am i missing ??
Thanks in advance.
I don't see any use of fetching template manually using $http.get
and then inserting it to DOM. you can simply give templateUrl
value in directive configuration and angular will fetch the template and compile it for you.
app.directive("partnersInfoView", function ($http) {
return {
restrict: 'A',
templateUrl: '/home/PartnerInfoTab',
link: function (scope, element, attr) {
// Do linking
}
};
});
And, your partnersInfoView
does not create isolated scope. so, you can access values of partnersInfoView
's parent scope value. see the below snippet.
var app = angular.module('app', []);
app.run(function($templateCache) {
// Simulating the fetching of /home/PartnerInfoTab template
var template = '<div id="PartnerInfoTab">' +
'<div class="form-group">' +
'<label class="col-md-2 control-label">Name</label>' +
'<div class="col-md-8">' +
'<input id="txt_name" class="form-control" type="text" ng-model="Data[0].firstName">' +
'<input id="txt_name" class="form-control" type="text" ng-model="Data[1].firstName">' +
'<input id="txt_name" class="form-control" type="text" ng-model="Data[2].firstName">' +
'</div>' +
'</div>' +
'</div>';
$templateCache.put('/home/PartnerInfoTab', template);
});
app.controller('GenericController', function($scope) {
$scope.Data = [{
"firstName": "John",
"lastName": "Doe"
}, {
"firstName": "Anna",
"lastName": "Smith"
}, {
"firstName": "Peter",
"lastName": "Jones"
}];
});
app.directive("partnersInfoView", function($http) {
return {
restrict: 'A',
templateUrl: "/home/PartnerInfoTab",
link: function($scope, element) {
// linking
}
};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app">
<div id="genericController" ng-controller="GenericController">
<div partners-info-view></div>
</div>
</div>
