在我的控制器中,我有以下用户数组,将通过部分html模板中的迭代显示
控制器中的:
vm.users = [
{"username": "johnDoe", "address": "Saltlake City, UT", "age": 34},
{"username": "janeDoe", "address": "Denver, CO", "age": 33},
{"username": "patrickDoe", "address": "San Francisco, CA", "age": 35}
];
部分HTML代码:
<div ng-repeat="user in mapView.users">
<my-customer info="user"></my-customer></div>
myCustomer指令: 我希望在客户端发生鼠标悬停事件时增加客户的年龄。是否可以在指令中执行此操作?
angular
.module('angularApp')
.directive('myCustomer', function() {
return {
restrict: 'E',
link: function(scope, element) {
element.bind('mouseover', function(e) {
e.target.age++; // this is not working, need help here!
console.log(e.target, 'mouseover');
});
},
scope: {
customerInfo: '=info'
},
templateUrl: 'views/directives/myCustomer.html'
};
}); //myCustomer
myCustomer模板:
<span>
<label class="label-success">Username: {{customerInfo.username}}</label>
</span>
<span>
<label class="label-default">{{customerInfo.address}}</label>
</span>
<span>
<label class="label-danger">{{customerInfo.age}}</label>
</span>

更多&#34; Angular&#34;做事方式是使用ng-mouseover
你可以把它放在&#34;部分html&#34;图
<my-customer
info="user"
ng-mouseover="user.age = user.age + 1;"></my-customer>
ng-mouseover
在Angular上下文中表达了表达式。这可确保一切都在Angular上下文中,您无需担心手动触发摘要。

per @floriban
您也可以将其置于指令模板本身
中<div ng-mouseover="customerInfo.age = customerInfo.age + 1;">
<span>
<label class="label-success">Username: {{customerInfo.username}}</label>
</span>
<span>
<label class="label-default">{{customerInfo.address}}</label>
</span>
<span>
<label class="label-danger">{{customerInfo.age}}</label>
</span>
</div>

e.target
是您已用鼠标移动的HTML元素。请改用真实用户信息:
element.bind('mouseover', function(e) {
scope.customerInfo.age++;
});
另外,您可以使用内置ng-mouseover
指令在HTML中执行所有操作。在views / directives / myCustomer.html中:
<div ng-mouseover="customerInfo.age++"> ... content of the template </div>
注意:您可能更喜欢ng-mouseenter不会在鼠标悬停的每个像素上触发事件,而只是在用鼠标进入区域时触发事件。
