eckig js Textfeld Wert leer, wenn Dropdown-Liste

Wenn Benutzer "Textbox-Wert-leer" auswählen, sollte Textbox deaktiviert und Textbox sollte gelöscht werden. Ich verwende unten Code für tun es. aber leider konnte ich es nicht tun. Wenn der Benutzer einen Wert eingibt und "text-box-value-empty" auswählt, sollte das Textfeld gelöscht werden.eckig js Textfeld Wert leer, wenn Dropdown-Liste

kann hilfreich sein: - [, wie der Wert des Modells im Hinblick auf leeren Drop-Down-Auswahl einstellen] (https://stackoverflow.com/questions/29197704/how-to-set- the-value-of-model-leer-auf-dropdown-selection-in-view) –

erste, machen die selectedOption und myVal als leere Objekte

$scope.myval = {} 
$scope.selectedOption = {};

Dann ordnen Sie das ng-Modell als die Eigenschaft jeder Variablen mit $index. Nutzen Sie auch die ng-disabled den Eingang

<div ng-repeat="a in myList"> 
    <select ng-model="selectedOption[$index]" ng-options="choice as choice for (idx, choice) in sizes.split(',')" ng-change="number($index)"> 

    </select> 

    <input ng-disabled="selectedOption[$index] == 'text-box-value-empty'" type="text" ng-model="myval[$index]"/> 
</div>

dann passieren die index an die number Funktion zu deaktivieren und die Werte leer

Demo machen

var app = angular.module('myApp', []); 
 
app.controller('myCtrl', function($scope) { 
 
    $scope.myList = [{ 
 
     text: "1", 
 
     value: "option_1" 
 
    }, { 
 
     text: "2", 
 
     value: "option_2" 
 
    }, ]; 
 
    $scope.myval = {} 
 
    $scope.selectedOption = {}; 
 
    $scope.sizes = "D,text-box-value-empty,"; 
 
    $scope.number = function(index) { 
 
     if ($scope.selectedOption[index] == 'text-box-value-empty')   { 
 
      $scope.myval[index] = '' 
 
     } 
 

 
    } 
 

 

 
});
