问题描述
HTML:
<label for="country">Country *</label>
<select id="country" ng-model="statessource" ng-options="country for (country, states) in countries"
ng-change="GetSelectedCountry()">
<option value=''>Select</option>
</select>
<label for="state">State *</label>
<select id="state" ng-disabled="!statessource" ng-model="model.state" ng-options="state for (state,city) in statessource"
ng-change="GetSelectedState()"><option value=''>Select</option>
</select>
<label for="city">City *</label>
<select id="city" ng-disabled="!citiessource || !statessource" ng-model="city"><option value=''>
Select</option>
<option ng-repeat="city in citiessource" value='{{city}}'>{{city}}</option>
</select>
JS:
$scope.countries = {
'USA': {
'Alabama': ['Montgomery', 'Birmingham'],
'California': ['Sacramento', 'Fremont'],
'Illinois': ['Springfield', 'Chicago']
},
'India': {
'Maharashtra': ['Pune', 'Mumbai', 'Nagpur', 'Akola'],
'Madhya Pradesh': ['Indore', 'Bhopal', 'Jabalpur'],
'Rajasthan': ['Jaipur', 'Ajmer', 'Jodhpur']
},
'Australia': {
'New South Wales': ['Sydney'],
'Victoria': ['Melbourne']
}
};
$scope.GetSelectedCountry = function () {
$scope.strCountry = document.getElementById("country").value;
};
$scope.GetSelectedState = function () {
$scope.strState = document.getElementById("state").value;
};
我已经在 JSON $sope.countries 上面编写了基于国家的州和城市.我的国家和州字段正在完美填充，但我的城市中没有任何项目.任何其他基于所选国家/地区填充州和城市的解决方案也有好处.
I have written above JSON $sope.countries to populate State and city based on country. My country and state field is populating perfectly, but my city is not having any item in it. Anyother solutions populating state and city based on selected country also will do good.
