在ng-repeat里面添加参数到ng-click函数似乎不起作用
我有一个简单的循环与ng-repeat
像这样:
<li ng-repeat='task in tasks'> <p> {{task.name}} <button ng-click="removeTask({{task.id}})">remove</button> </li>
控制器$scope.removeTask(taskID)
有一个函数。
据我所知,Angular将首先呈现视图,并用一个数字replace插入的{{task.id}}
,然后在点击事件时,将评估ng-click
string。
在这种情况下, ng-click
会完全得到预期的结果,即: ng-click="removeTask(5)".
然而…这没有任何事情。
当然,我可以编写一个代码来从$tasks
数组或甚至DOM获取task.id
,但是这看起来不像Angular方式。
那么,如何在ng-repeat
循环中添加dynamic内容到ng-click
指令呢?
代替
<button ng-click="removeTask({{task.id}})">remove</button>
做这个:
<button ng-click="removeTask(task.id)">remove</button>
请看这个小提琴:
有一件事情真的让我感到困扰,当时我在浏览器中检查了这个html,而不是把它扩展成如下forms:
<button ng-click="removeTask(1234)">remove</button>
我看见:
<button ng-click="removeTask(task.id)">remove</button>
但是,后者的作品!
这是因为你在“Angular World”里面,当在ng-click =“”时,angular度准备好了解task.id,就像你在模型里面一样。 不需要使用数据绑定,如{{}}。
此外,如果您想要传递任务对象本身,您可以:
<button ng-click="removeTask(task)">remove</button>
另外值得注意的是,对于在search中find这个的人来说,这是…
<div ng-repeat="button in buttons" class="bb-button" ng-click="goTo(button.path)"> <div class="bb-button-label">{{ button.label }}</div> <div class="bb-button-description">{{ button.description }}</div> </div>
请注意ng-click
的值。 传递给goTo()
的参数是绑定对象( button
)属性的string,但不包含在引号中。 看起来像AngularJS为我们处理。 我挂了几分钟。
这工作。 谢谢。 我注入自定义的HTML并在控制器中使用angular度编译它。
var tableContent= '<div>Search: <input ng-model="searchText"></div>' +'<div class="table-heading">' + '<div class="table-col">Customer ID</div>' + ' <div class="table-col" ng-click="vm.openDialog(c.CustomerId)">{{c.CustomerId}}</div>'; $timeout(function () { var linkingFunction = $compile(tableContent); var elem = linkingFunction($scope); // You can then use the DOM element like normal. jQuery(tablePanel).append(elem); console.log("timeout"); },100);
以上答案是非常好的。 你可以看下面的完整的代码示例,以便你可以完全知道如何使用
var app = angular.module('hyperCrudApp', []); app.controller('usersCtrl', function($scope, $http) { $http.get("https://jsonplaceholder.typicode.com/users").then(function (response) { console.log(response.data) $scope.users = response.data; $scope.setKey = function (userId){ alert(userId) if(localStorage){ localStorage.setItem("userId", userId) } else { alert("No support of localStorage") return } }//function closed }); });
