【问题描述】:
我正在尝试使用 Angular directive 构建密码匹配机制,但我似乎遗漏了一些东西。我定义了ng-app 和ng-controller,但我仍然收到一条错误消息,指出module 未定义。
jsfiddlehere.
Uncaught Error: [$injector:modulerr] Failed to instantiate module myApp due to:
Error: [$injector:nomod] Module 'myApp' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
HTML:
<div ng-app="myApp">
<div class="row" ng-controller='Ctrl'>
<form name="form1">
<div class="col-xs-12 col-sm-6 col-md-6">
<div class="form-group">
<input type="password" ng-model="login.password" name="password" id="password" class="form-control input-lg" placeholder="Password" tabindex="5">
</div>
</div>
<div class="col-xs-12 col-sm-6 col-md-6">
<div class="form-group">
<input ng-model="login.verify" type="password" name="verify" placeholder="Confirm Password" nx-equal="login.password" class="form-control input-lg" tabindex="6">
<div class="error" ng-show="form1.verify.$error.nxEqual">Passwords are not equal</div>
</div>
</div>
</form>
</div>
</div>
JS:
var app = angular.module("myApp", []);
app.controller("Ctrl", function($scope){
});
app.directive('nxEqual', function() {
return {
require: 'ngModel',
link: function(scope, elem, attrs, model) {
if (!attrs.nxEqual) {
console.error('nxEqual expects a model as an argument!');
return;
}
scope.$watch(attrs.nxEqual, function(value) {
model.$setValidity('nxEqual', value === model.$viewValue);
});
model.$parsers.push(function(value) {
var isValid = value === scope.$eval(attrs.nxEqual);
model.$setValidity('nxEqual', isValid);
return isValid ? value : undefined;
});
}
};
});
【问题讨论】:
-
你定义控制器Ctrl了吗?
-
你确定你在页面上引用了角度控制器和指令
js文件吗? -
谢谢,我做了,但忘记更新了。同样的错误。
-
@PankajParkar,整个脚本位于同一页面中的
script标记内。 -
@undroid 你能把那个脚本加载部分添加到有问题的地方吗?
