在AngularJS中禁用不需要的验证(条件验证)
dea*_*anN 10 javascript validation angularjs angularjs-directive
我有一个需要验证的表单.
表单包含许多部分,默认情况下会禁用其中一些部分.每个字段中的值都是正确的,但它违反了我的验证指令.例如,当它禁用时它应该包含0,但是当它可编辑时它应该包含其他内容.无论如何,我附加一个禁用指令给他们,并把它们放下.
当我提交表单(使用角度范围函数)时,if ($scope.sarfaslForm.$invalid)- >返回true.它说我检查$scope.sarfaslForm.$error列表时有两个无效字段.
在此博客之后,我实施了我的验证:http: //blog.yodersolutions.com/bootstrap-form-validation-done-right-in-angularjs/
在这个线程之后,我创建了一个指令来忽略我的一些禁用控件:
我对这个指令做了一个小改动:
.directive('hsDisableValidation', function() {
return {
require: '^form',
restrict: 'A',
link: function(scope, element, attrs,form) {
var control;
scope.$watch(function() {
return scope.$eval(attrs.hsDisableValidation);
}, function(value) {
if (!control) {
control = form[element[0].name];
//form[element.find("input").attr("name")];
}
if (value === false) {
form.$addControl(control);
angular.forEach(control.$error, function(validity, validationToken) {
form.$setValidity(validationToken, !validity, control);
});
} else {
form.$removeControl(control);
//In Here: I tried to $setValidity of controls to true, Remove Error List, and Remove Validator Function, but these things didn't worked out
}
});
}
}
})
这里验证总是对我失败:PS:因为我在'text'类型的字段上使用它,我没有最小/最大值,只有最小/最大长度.我确定这不是问题,但我要包含这些代码以确保.
.directive('hsMinValue', function() {
return {
require: 'ngModel',
link: function (scope, elem, attr, ngModel) {
function isLesser(value) {
var minVal = parseInt(attr.hsMinValue);
return parseInt(value) < minVal;
}
function validate(value) {
var valid = !isLesser(value);
ngModel.$setValidity('minValue', valid);
return valid ? value : undefined;
}
ngModel.$parsers.unshift(function (value) {
ngModel.$setValidity('minValue', !isLesser(value));
return value;
});
ngModel.$formatters.unshift(function (value) {
ngModel.$setValidity('minValue', !isLesser(value));
return value;
});
}
}
});
然后我保存:
saveSarfasl: function () {
$scope.$broadcast('show-errors-check-validity');
if ($scope.sarfaslForm.$invalid) { --> True :|
return;
}
//Stuffs
}

编辑2:
当我使用它时,所有控件都可以自行查看每个控件.但是在我的函数中提交(提交按钮是正常按钮,但没有效果,但调用我的函数)后,我看到整体结果中的错误:
$scope.sarfaslForm.$invalid==>true
好吧，这是您的代码所做的假设。当您查看检查验证时，您正在检查 value === false 是否存在，否则您会将其添加到表单中，这不是您想要描述的逻辑。
您所说的是，无论值如何，如果该字段被禁用并设置为 0，我希望将其从表单中删除，那么如果该值为 false，我希望将其从表单中删除，否则验证表单。只需进行逻辑检查即可查看该字段是否已禁用，并将其从验证中删除。
if (value === 0) {
form.$removeControl(control);
} else if (value === false) {
form.$addControl(control);
angular.forEach(control.$error, function(validity, validationToken) {
form.$setValidity(validationToken, !validity, control);
});
} else {
form.$removeControl(control);
}
