我希望你能帮助我。
我想我错过了一些东西，而且无法理解。由于某些原因，我在填写表单时无法启用ng-disabled="formSubmmision"来启用按钮。
任何帮助将不胜感激！
我有以下视图和控制器：
以下是我的观点：
<section class="mainbar" data-ng-controller="adminVendorNumberController as vm">
<article class="booty">

这是我的控制器：

您使用的是CONTROLLER AS语法。
你的控制器应该......
var vm = this;
不......
var vm = $scope;
你也应该使用......
formInsertVendorNumber。$有效以禁用或启用提交按钮。
你应该在表格中显示......
<span>{{ formInsertVendorNumber }}</span>
这将输出许多与表单相关的角度变量。您应该看到formInsertVendorNumber。当表单有效时，$ valid为true，否则为false。用它来切换你的按钮。

我通过向控制器添加另一个名为 formSubmit（）的简单函数解决了我的问题：
function getItemGroupById(itemGroupId) {
return $http.get("/api/itemGroup/GetItemGroupById/?itemGroupId=" + itemGroupId)
.then(Success)
.then(formSubmit)
.catch(Failure);
function Success(responce) {
vm.itemGroupSelected = responce.data.Records;
return vm.itemGroupSelected, responce.data;
}
function Failure(error) {
logger.error('Failed to get Vendor Data ' + error.data.Message);
}
}
function formSubmit() {
vm.formSubmmision = false;
return vm.formSubmmision;
}
