如何根据参数值更改checkbok状态? 示例:JSFiddle
HTML:
<body ng-app="myApp">
<div ng-controller="rangeCtrl">
Param:{{param}}
<hr>
<div>modelValue:{{modelValue}}</div>
<input type="checkbox" style="width: 300px;"
ng-change = "rangeChange()"
ng-checked = "modelValue"
ng-model = "modelValue">
</div>
</body>
JS:
var app = angular.module('myApp', []);
app.controller('rangeCtrl', function($scope, $interval, $timeout) {
(function update() {
$timeout(update, 1000);
$scope.param = Math.round((Math.random()));
}());
$scope.$watch('param',
function(newVal, oldVal) {
if (newVal == oldVal) {
$scope.modelValue = oldVal;
}
});
$interval(function() {
$scope.$watch('param',
function(newVal, oldVal) {
if (newVal !== oldVal) {
$scope.modelValue = newVal;
}
});
}, 25);
$scope.rangeChange = function() {
}
});
我认为问题在于参数不是布尔值。

如果您使用
,您的小提琴将起作用ng-checked = modelValue === 1
(假设您希望在值为1时检查它)
