在 ng-init 中声明多个值

Question

So I'm wondering how I can declare multiple values within a single ng-init, without having to create some weird hash, that then I need to always access specifically.

so basically I would like

<div ng-init="a = 1, b = 2">{{a}}</div>

and I'm saying that I would like to avoid having to do

<div ng-init="unecessary_bs = {a: 1, b: 2}">{{unecessary_bs.a}}</div>

However the reasonable :

<div ng-init="a = 1, b = 2">{{a}}</div>

doesn't seem to work.

Anticipated Thanks

Use a function, way more readable:

ng-init="init()"

And:

$scope.init = function() {
    $scope.a = 1;
    $scope.b = 2;
}

Or, if you must, separate inline variables with a semi-colon:

ng-init="a = 1; b = 2"

Sometimes its not ideal to put the variables in a function. For example your backend is in express and you are rendering a file using jade.

With Express.js you can send local variables to the html. Angular can accept these variables with

ng-init=""

Using ";" one can have multiple variables

Example

ng-init=" hello='world'; john='doe' "

我更喜欢用对象初始化变量包装：

<div ng-init="initObject = {initParam: 'initParamValue', anotherOne: 'value'}"></div>

 <div ng-app="app">
  <div ng-controller="TodoCtrl">
    <ul>
      <li ng-repeat="todo in todos" ng-init='initTodo = init(todo)'>
        <span class="done-{{todo.done}}">{{todo.text}} |
                               and todo.text via init:{{initTodo}}</span>
      </li>
    </ul>

  </div>

  var modulse = angular.module("app",[]);

  modulse.controller("TodoCtrl", function ($scope)  {

            $scope.todos = [ {text:'todo1'}, {text:'todo2'}]; 

            $scope.init = function (todo) {  return todo.text; };

  });

只需用半冒号{{a}}代替昏迷即可
