问题描述
最近在用AngularJs写下拉联动，但是困在了第二个下拉框值的显示和联动数值post的问题上，希望各位大神帮助
问题：
第二个下拉框值如何显示
post提交后的值怎么处理？现在第一个下拉框post后的值是object:3，如何转化成json里的数值
html代码：
<p ng-app=’angular_post_demo’ ng-controller=’sign_up’> <input type='text' size='40' ng-model='email'><br> <input type='password' size='40' ng-model='password'> <br> <select ng-options='universit.uni for universit in arr' ng-model='university'></select> <br> <select ng-options='student for university in arr' ng-model='student'></select> <br> <button ng-click='check_credentials()'>Login</button> <br> <span id='message'></span></p>
js代码：
var app = angular.module(’angular_post_demo’, []); app.controller(’sign_up’, function($scope, $http) {$scope.arr = [{ 'uni': 'TS', 'stu': ['Tom', 'HHH', 'KKK']}, { 'uni': 'SDU', 'stu': ['AA', 'BBB']}, { 'uni': 'SDUT', 'stu': ['CCC', 'DD']}];$scope.university = $scope.arr[0];$scope.check_credentials = function() { document.getElementById(’message’).textContent = ''; var request = $http({method: 'post',url: window.location.href + 'res.php',data: { email: $scope.email, pass: $scope.password, university: $scope.university // student: $scope.student} }); request.success(function(data) {document.getElementById(’message’).textContent = data; });} });
问题解答
回答1：university的select加ngchange触发
post的对象后处理具体看你什么语言
