我有一个包含5个问题的表格,每个问题有3个不同的答案。
例如
q1。你最喜欢什么颜色?
单选按钮-1。值蓝色
单选按钮2。值红色
单选按钮3。灰色值
这些问题大多数都具有相同的值(蓝色,红色,灰色),这是我想要的,但是,我试图将所有值加到表格的末尾,以便我确定该人是否填写了形式等于值之一(蓝色,红色或灰色)。
我正在用angularjs构建这种形式,这就是我到目前为止所拥有的。
<label>Q1. what is your favorite color?</label>
<div class="form-group">
<div class="radio">
<label>
<input type="radio" ng-model="formData.color" value="blue">
blue
</label>
</div>
<div class="radio">
<label>
<input type="radio" ng-model="formData.color" value="red">
red
</label>
</div>
<div class="radio">
<label>
<input type="radio" ng-model="formData.color" value="grey">
grey
</label>
</div>
只有当我已经将值输入到变量中时,此代码段才有效
$scope.formData = { };
$scope.formData = [];
$scope.formData.sort();
var current = null;
var cnt = 0;
for (var i = 0; i < $scope.formData.length; i++) {
if ($scope.formData[i] != current) {
if (cnt > 0) {
console.log(current + ' shows ' + cnt + ' times');
}
current = $scope.formData[i];
cnt = 1;
} else {
cnt++;
}
}
if (cnt > 0) {
console.log(current + ' shows ' + cnt + ' times');
}
最佳答案
这是示例解决方案plunker。能行吗?
控制者
$scope.questions = [
'Q1. what is your favorite color?',
'Q2. what color is your car?',
'Q3. what color best represents you?'
];
$scope.formData = [];
$scope.stats = function() {
$scope.results = {};
for (var i = 0; i < $scope.formData.length; i++) {
var color = $scope.formData[i];
if(color) {
if ($scope.results.hasOwnProperty(color)) {
$scope.results[color]++;
} else {
$scope.results[color] = 1;
}
}
}
};
