如何僅基於freqValue從html中設置最小值，最大值。設置輸入類型的最小值，最大值=基於angularjs中下拉值的數字
<input type="number" min="0" max="100" ng-model="interval" /> <select ng-model="freqValue" ng-options="f.key as f.value for f in freq"> </select>
可以具有與這些頻率值作爲它的密鑰存儲用於min和max值的地圖每個頻率，以便在模型更改時，angularjs將根據地圖索引（即freqValue變量）重新綁定min和max值。
例如：
控制器：
$scope.map = {
'1': { min: 1, max: 20 },
'2': { min: 1, max: 45 },
'3': { min: 1, max: 100 },
};
模板：
<input type="number"
min="{{ map[freqValue].min }}"
max="{{ map[freqValue].max }}"
ng-model="interval" />
<select
ng-model="freqValue"
ng-options="f.key as f.value for f in freq">
</select>
嘗試這樣
(function() {
var app = angular.module('app', []);
app.controller('main', ['$scope', function($scope) {
var vm = this;
vm.freq = [{key:1},{key:2},{key:3}]
vm.setMinMax = function() {
if (vm.freqValue == 1) {
vm.min = 1;
vm.max = 20;
}
if (vm.freqValue == 2) {
vm.min = 1;
vm.max = 45;
}
if (vm.freqValue == 3) {
vm.min = 1;
vm.max = 100;
}
}
}]);
})();<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<html lang="en" ng-app="app">
<body ng-controller="main as vm">
<select ng-model="vm.freqValue" ng-options="f.key as f.key for f in vm.freq" ng-change="vm.setMinMax()">
<option value="">select</option>
</select>
<input type="number" ng-min="{{vm.min}}" max="{{vm.max}}" ng-model="interval" />
</body>
