Rah*_*ran 10 javascript angularjs single-page-application

我是这个框架的新手,因此练习Angularjs并遵循网站上提供的教程.

有一个例子我们可以搜索表中的数据,例子如下,

<!DOCTYPE html>
<html ng-app="SmartPhoneApp">
<head>
    <title>Smart phone Angular</title>      
    <script type="text/javascript" src="D:/Rahul Shivsharan/Installers/AngularJS/angular.js"></script>
    <script type="text/javascript">
        var smartPhoneApp = angular.module("SmartPhoneApp",[]);

        smartPhoneApp.controller("phoneCtrl",function($scope){
            $scope.phones = [
                {
                    "modelName" : "LUMIA 520",
                    "companyName" : "NOKIA"
                },
                {
                    "modelName" : "GALAXY S Series",
                    "companyName" : "SAMSUNG"
                },
                {
                    "modelName" : "CANVAS",
                    "companyName" : "MICROMAX"
                },
                {
                    "modelName" : "OPTIMUS",
                    "companyName" : "LG"                        
                }
            ];

        });
    </script>   
</head>
<body>  
    Search by Model Name : <input ng-model="comp.modelName" />  
    Search by Company : <input ng-model="comp.companyName" />   
    <div ng-controller="phoneCtrl">
        <table ng-repeat="phone in phones | filter: comp">
            <tr>
                <td>{{phone.modelName}}</td>
                <td>{{phone.companyName}}</td>
            </tr>
        </table>
    </div>
</body>

Here in the above code i am able to search the phone using two different inputs i.e. search by model Name and search by company Name , the above code runs fine,

But what if i need to search by using the type of search present in the select options,

the code is as follows

<!DOCTYPE html>
<html ng-app="EmployeeApp">
<head>
    <title>Orderring People</title>     
    <script type="text/javascript" src="D:/Rahul Shivsharan/Installers/AngularJS/angular.js"></script>
    <script type="text/javascript">
        var employeeApp = angular.module("EmployeeApp",[]);
        employeeApp.controller("empCtrl",function($scope){
            $scope.employees = [

From the above code you can see that i am trying to achieve is search employee by "Name", "Company" or "Designation" present in the selection box,

but i am going wrong here,

the ng-model query doesn't picks up the right mapping, or may be i am doing in a wrong way,

can you please tell me how will i achieve this,

which part of the code should i change

我创造了一个plunkr.您可以在搜索查询上定义要过滤的属性.在选择中,选择要过滤的属性并将其分配给搜索查询.
