我有以下backbone.js代码,并在该事件中遇到问题,然后我从集合中触发“添加”事件。在success:
提取中添加this.field.add(list_fields);
导致错误。我如何确保模型被提取然后添加事件运行后Backbone.js添加事件问题
$(function() {
$(".chzn-select").chosen();
/*********************************Models*************************************************/
var Table = Backbone.Model.extend({
urlRoot : '/campusfeed/index.php/welcome/generate'
});
var Field = Backbone.Model.extend({
urlRoot: '/campusfeed/index.php/welcome/generate'
});
/**************************Collections*************************************************/
Tables = Backbone.Collection.extend({
//This is our Friends collection and holds our Friend models
initialize : function(models, options) {
this.bind("add", options.view.addFriendLi);
//Listen for new additions to the collection and call a view function if so
}
});
var Fields = Backbone.Collection.extend({
model:Field,
url:'http://localhost/campusfeed/index.php/welcome/generateFields',
initialize : function(models, options) {
this.bind("add", options.view.getFields);
}
});
/************************************Views**************************************************/
var m="shit";
var app = Backbone.View.extend({
el:'body',
initialize:function(model,options){
//Create collections in here
this.table = new Tables(null,{
view : this
});
this.field = new Fields(null,{
view : this
});
},
events : {
"click #choose" : "generate"
},
generate:function(){
var table = (this.$("#table option:selected").text());
var dbname = (this.$("#database").text());
var list_fields = new Field();
list_fields.urlRoot = list_fields.urlRoot+"/"+dbname+"/"+table;
list_fields.fetch({
success:function(){
console.log(JSON.stringify(list_fields));
}
});
this.field.add(list_fields);
},
getFields:function(model){
console.log(JSON.stringify(model));
}
});
var apprun = new app;
/* var data = new Fields();
data.url=data.url+"/some/data";
alert(data.url);
data.fetch();
var staff = new Table();
staff.fetch();
var field = new Field();*/
});
