角JS - 動態值基於單選按鈕的選擇總和

鑑於有單選按鈕的兩個列表角JS - 動態值基於單選按鈕的選擇總和

<input type="radio" name="SET1" ng-model="SET1Selected" value="1"> 1 
<input type="radio" name="SET1" ng-model="SET1Selected" value="2"> 2 
<input type="radio" name="SET1" ng-model="SET1Selected" value="3"> 3

<input type="radio" name="SET2" ng-model="SET2Selected" values="4"> 4 
<input type="radio" name="SET2" ng-model="SET2Selected" value="5"> 5 
<input type="radio" name="SET2" ng-model="SET2Selected" value="6"> 6 

<div> {{value of radio button selected from L1}}+{{value of radio button selected from L2}}</div>

薩姆將根據從選擇改變L1和L2

@Sajeetharan。請看看我的下一個查詢。:) – Groovy

您可以使用表達式

<div> {{parseInt(SET1Selected)+parseInt(SET2Selected) }}</div>

DEMO

var app = angular.module("myApp", []); 
 
app.controller("myCtrl", ['$scope', function($scope) { 
 
$scope.parseInt = parseInt; 
 

 
}]);

<!DOCTYPE html> 
 
<html ng-app="myApp"> 
 

 
<head> 
 
    <meta charset="utf-8" /> 
 
    <script src="https://code.angularjs.org/1.4.7/angular.js"></script> 
 
    <script src="app.js"></script> 
 
</head> 
 

 
<body ng-controller="myCtrl"> 
 
    <div class="row"> 
 
    <input type="radio" name="SET1" value="1" ng-model="SET1Selected" > 1 
 
    <input type="radio" name="SET1" value="2" ng-model="SET1Selected" > 2 
 
    <input type="radio" name="SET1" value="3" ng-model="SET1Selected" > 3 
 
    </div> 
 
    <div class="row"> 
 
    <input type="radio" name="SET2" value="4" ng-model="SET2Selected" > 4 
 
    <input type="radio" name="SET2" value="5" ng-model="SET2Selected" > 5 
 
    <input type="radio" name="SET2" value="6" ng-model="SET2Selected" > 6 
 
    </div> 
 
    <div class="row"> 
 
    <div> {{parseInt(SET1Selected)+parseInt(SET2Selected) }}</div> 
 
</body> 
 

 
</html>

如果我不直接在值=「4」中提供值，該怎麼辦？我的價值將是一個對象的關鍵，我將循環使用單選按鈕，並在值中顯示不同的鍵，例如value =「XYZ」。 – Groovy

仍然你要綁定一個變量，所以它將是相同的 – Sajeetharan

標記作爲答案，如果它已經幫助 – Sajeetharan

小提示如下，你可以用它

{{(SET1Selected - 0) + (SET2Selected - 0)}}

或者

{{(SET1Selected*1) + (SET2Selected*1)}}
