在JS文件中使用带有ember的If语句

Question

I am not sure how this works but i need to put an if statement in the following code. I know Javascript but not ember, still learning it as I go My file is called: CatalogueListController.js and the code with in:

App.CataloguelistController = Em.ArrayController.extend(Ember.PaginationSupport, {
needs: ["search", "accountBrowse"],
content: [],
total: 0,
isLoading: false,
outofcount: 0,
searchquery: '',
classid: 0,
attributelist: '',
processguid: '',
quotetypeMetaBinding: "App.metaDataController.QUOTETYPE",

addToBulk: function(context) {
        var self        = this,
    accountguid = App.selectedAccountGuid,
    quotetype   = (context && context.metacode) ? context.metacode : App.currentQuotetype,
    itemArray   = [];

       //some more code here    
},

//i need to put the if here if it is for a certain accountguid then have 
    currentViewList: true,
currentViewBulk: false,


    //else have this
currentViewList: false,
currentViewBulk: true,

mainPage: false,

andOr: [
    {"name": "Match All", "value": "AND"},
    {"name": "Match Any", "value": "OR"}
],
andOrSelected: 'AND',

i have put in comments where i need to have the if. Any help please? thanks

On init conditionally set those properties:

App.CataloguelistController = Em.ArrayController.extend(Ember.PaginationSupport, {
init: function(){
  this._super(); 
  if(//somecondition){
    this.set('currentViewList', true);
    this.set('currentViewBulk', false);
  }else{
  // set them to something else..
  }
}

You can use computed properties. Also if you ever need to, you can bind computed properties with other properties that may change dynamically.( http://emberjs.com/guides/object-model/computed-properties/ )

App.CataloguelistController = Em.ArrayController.extend(Ember.PaginationSupport, {
  needs: ["search", "accountBrowse"],
  .....

  currentViewList:function(){
    if(/*it is for a certain accountguid*/){
      return true;
    }else{
      return false;
    }
  }.property(),
  currentViewBulk:function(){
    if(/*it is for a certain accountguid*/){
      return true;
    }else{
      return false;
    }
  }.property(),
