我有一个带有文本输入和验证消息的表单,如果输入发生变化则必须显示该表单。 (这个例子没有任何意义,但它被简化为基本问题) 我想在angularJS指令中生成的是:
<p>Username:<br>
<input type="text" name="user" ng-model="user" required>
<span style="color:red" ng-show="myForm.user.$dirty"> Username is dirty.</span>
</p>
请参阅此处的示例。 (静态密码代码有效,生成的用户代码不可用)
var app = angular.module('myApp', []);
app.controller('myCrtl', function($scope) {
$scope.user = 'MyName';
$scope.passwd = 'MyPw';
})
.directive("mytest", function($compile){
return{
scope: true,
link: function(scope, element){
var template = '<input type="text" name="user" ng-model="user" required>'+
'<span style="color:red" ng-show="myForm.user.$dirty">'+
'Username is dirty.</span>';
var tmpFn= $compile(template);
var content = tmpFn(scope);
element.append(content);
}
}
});

<h2>Validation</h2>
<form ng-app="myApp" ng-controller="myCrtl"
name="myForm" novalidate>
<!-- the generated code does not work -->
<p mytest>User:<br>
</p>
<!-- the static code works-->
<p>Password:<br>
<input type="text" name="passwd" ng-model="passwd" required>
<span style="color:red" ng-show="myForm.passwd.$dirty">
Password is dirty.</span>
</p>
</form>
</body>
</html>

问题似乎是myForm.user是在指令
中创建的答案 0 :(得分:0)
删除范围:true,因此您的指令不会创建新范围并设置优先级。如果不能尝试使用此指令
function dynamicName($compile) {
return {
restrict: 'A',
terminal: true,
priority: 1000,
link: function (scope, element, attrs) {
var name = scope.$eval(attrs.dynamicName);
if (name) {
element.attr('name', name);
element.removeAttr('dynamic-name');
$compile(element)(scope);
}
}
};
}
像这样使用
<input dynamic-name="inputName">
