我有一系列行,每个行都有一个复选框。每行有几个输入。我已经进行了验证,需要在所有行中至少选中一个复选框。但是,到目前为止,我无法要求输入仅对选中的复选框有一个值。
的HTML:
<div style="width: 100%;">
<checkboxgroup-Wheelbase min-required="1">
<table style="width: 100%">
<tr>
<td>
<table style="width: 97%;">
<tr>
<th style="width: 220px;" class="wheelbaseHeaderCell">Wheelbase<br /><span style="font-weight: 400;">(choose min of 1)</span></th>
<th class="wheelbaseHeaderCell">Payload<br />[ pounds ]</th>
<th class="wheelbaseHeaderCell">Length<br />[ inches ]</th>
<th class="wheelbaseHeaderCell">Height<br />[ inches ]</th>

要求至少选中一个复选框的指令:
.directive('checkboxgroupWheelbase', function() {
return {
restrict: 'E',
controller: function($scope, $attrs) {
var self = this;
var ngModels = [];
var minRequired;
self.validate = function() {
var checkedCount = 0;
angular.forEach(ngModels, function(ngModel) {
if (ngModel.$modelValue) {
checkedCount++;
}
});
console.log('minRequired', minRequired);
console.log('checkedCount', checkedCount);
var minRequiredValidity = checkedCount >= minRequired;
angular.forEach(ngModels, function(ngModel) {
ngModel.$setValidity('checkboxgroupWheelbase-minRequired', minRequiredValidity, self);
});
};
self.register = function(ngModel) {
ngModels.push(ngModel);
};
self.deregister = function(ngModel) {
var index = this.ngModels.indexOf(ngModel);
if (index != -1) {
this.ngModels.splice(index, 1);
}
};
$scope.$watch($attrs.minRequired, function(value) {
minRequired = parseInt(value, 10);
self.validate();
});
}
};
})
是否有一种简单、优雅的方法来要求这些复选框的输入字段是必需的?它通过“规则”在 JQuery 中直接出现,但我还没有找到通过 AngularJs 做到这一点的方法。有人建议我使用子表单,但我无法想象它的实现。
万一我不够清楚:
对于选中相应复选框的任何行,该行的所有输入都需要有一个值。因此,如果选中第 1,3 和 5 行的复选框,则第 1,3 和 5 行的输入需要值。如果选中了一行的复选框,则同一行的输入需要一个值。如果未选中该行的复选框,则不需要这些输入。在清除这一点时,我认为明智的做法是禁用所有输入,直到它们各自的轴距复选框被选中。
更新:
我要感谢 user2104976 让我考虑更好的用户体验,只要确保在未选中相应的轴距复选框时不添加输入值,所以我实现了这个
**"ng-disabled="!wheelbase.checked"**
在每个相应的输入中。多谢,伙计!!现在如何解决我原来的问题,哈哈!
