我是AngularJS的新手,正在尝试弄清楚如何根据变量值显示HTML元素。
我试过这个:
<div id="checkoutForm" class="form" ng-show="$scope.matchCount==1">
</div>
和此:
<div id="checkoutForm" class="form" ng-show="matchCount==1">
</div>
到目前为止,这是我的代码:
<div id="visitorForm" class="form" ng-controller="VisitorLogController">
<input id="firstNameTb" ng-model="formData.FIRSTNAME" placeholder="@Model.FirstNameStr" ng-blur="findUser()" class="form-control" value="{{FIRSTNAME}}"/>
<input id="lastNameTb" ng-model="formData.LASTNAME" placeholder="@Model.LastNameStr" ng-blur="findUser()" class="form-control" value="{{LASTNAME}}" />
<input id="companyTb" ng-model="formData.COMPANYNAME" placeholder="@Model.CompanyStr" ng-blur="findUser()" class="form-control" value="{{COMPANYNAME}}" />
<input id="codeTb" ng-model="formData.CHECKCODE" placeholder="@Model.CodeString" title="@Model.CodeStringDesc" ng-blur="findUser()" class="form-control" />
</div>
<div id="checkoutForm" class="form" ng-show="matchCount==1">
<h3>@Html.Raw(@Model.RecordFoundStr)</h3>
</div>
在我的.js文件中:
function VisitorLogController($scope, $http) {
$scope.matchCount = null;
$scope.findUser = function () {
$http({
method: 'POST',
url: rootUrl + "VisitorLog/Check",
data: $.param($scope.formData),
headers: { 'Content-type': 'application/x-www-form-urlencoded' }
}).success(function (data) {
$scope.matchCount = data.count;
if (data.count == 1) {
$scope.FIRSTNAME = data.visitors[0].FirstName;
$scope.LASTNAME = data.visitors[0].LastName;
$scope.COMPANYNAME = data.visitors[0].CompanyName;
}
$scope.message = data.message;
});
}
}
该函数按预期触发,我可以看到计数并验证$ scope.matchCount是否正确地使用记录计数进行更新,但它根本不会影响UI。
我错过了什么?
答案 0 :(得分:7)
div
ng-show="matchCount==1"
位于scope
的{{1}}之外。
移动VisitorLogController
中的ng-show
应该会有效。
scope
