我有一个时间帧控件,可以递增/递减某个值为几个月的输入。有一个向右箭头增加输入的值(即1月 - > 2月),左箭头递减它,用户可以编辑输入本身以在不同的月份输入。
然而,时间帧控制的行为真的很奇怪。当我点击其中一个错误时,它会将输入值更改为""
。当我再次点击时,它将转到正确的月份。当我再次点击时,它会清除输入,并在清除输入和转到正确月份之间来回切换。
例如:如果我连续点击右箭头5次,输入的值将为:
January
""
March
""
May
这个错误是什么?这是我的相关代码:
myApp.controller('TimeframeCtrl', ['$scope',
'$cookieStore',
function ($scope, $cookieStore) {
// Create array of month names
var month_dictionary = [
'January',
'February',
'March',
'April',
'May',
'June',
'July',
'August',
'September',
'October',
'November',
'December'];
// If month cookie doesn't exist
if ($cookieStore.get('month') == null) {
// Create month cookie
$cookieStore.put('month', 0);
}
// If year cookie doesn't exist
if ($cookieStore.get('year') == null) {
// Create year cookie
$cookieStore.put('year', 2014);
}
// Go to the previous month
$scope.prevMonth = function () {
// Handle corner cases of month looping
var month_helper = (
$cookieStore.get('month') - 1 == -1) ? 11 : $cookieStore.get('month') - 1;
// Update month scope variable
$scope.month = month_dictionary[month_helper];
// Update month cookie
$cookieStore.put('month', month_dictionary[month_helper]);
}
// Go to the next month
$scope.nextMonth = function () {
// Handle corner cases of month looping
var month_helper = ($cookieStore.get('month') + 1 == 12) ? 0 : $cookieStore.get('month') + 1;
// Update month scope variable
$scope.month = month_dictionary[month_helper];
// Update month cookie
$cookieStore.put('month', month_helper);
}
// Watch for manual editing of month
$scope.$watch('month', function () {
// Update month cookie
$cookieStore.put('month', month_dictionary.indexOf($scope.month));
// Remove warning class
$('.month-control').removeClass('warning-input');
});
// Set timeframe control values
$scope.month = month_dictionary[$cookieStore.get('month')];
// Test whether or not form inputs are valid
$scope.submitForm = function ($valid) {
// If so, update graphs
if ($valid) {
// Update graphs
// If not, add proper warning classes
} else {
if ($scope.month == undefined) {
$('.month-control').addClass('warning-input');
}
}
}
}]);
如果有人也需要HTML,我可以添加它。非常感谢。
编辑:HTML
<form class="navbar-form pull-left" name="timeframeForm" ng-controller="TimeframeCtrl" ng-submit="submitForm(timeframeForm.$valid)">
<div class="timeframe"><i class="fa fa-calendar fa-l"></i>Timeframe</div>
<i class="fa fa-angle-left" ng-click="prevMonth()"></i>
<input class="form-control month-control" type="text" value="{{month}}" placeholder="Month" ng-model="month" ng-pattern="/January|February|March|April|May|June|July|August|September|November|December/g"/>
<i class="fa fa-angle-right" ng-click="nextMonth()"></i>
<button class="btn btn-refresh"><i class="fa fa-refresh"></i></button>
</form>

问题是HTML中g
正则表达式末尾的ng-pattern
字符。从两个正则表达式中删除g
解决了这个问题。不确定为什么(这个资源更好地解释了它:What does the regular expression /_/g mean?),但似乎g
用空格替换月份。不完全确定为什么它在每次点击箭头键时都这样做,但很高兴问题解决了
