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上方编写了基于国家/地区的州和城市信息. 我的国家和州田地人口稠密，但我的城市中没有任何物品.根据选定国家/地区填充州和城市的任何其他解决方案也都可以.
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.
