好吧,我正在用jQuery UI对一组仪表板小部件进行排序,并希望保留小部件的新顺序。什么是最好的方法呢?有任何想法吗?Backbone.js集合保留新的排序顺序?
我在想,像这样的模型中给“秩序”的属性:
widgetsModel: Backbone.Model.extend({
defaults: {
name: 'Widget',
category: 'uncategorized',
order: '0',
content: 'No Content'
},
initialize: function(i) {
this.bind("change:name", function() {
var name = this.get("name");
console.log('From Model: '+name);
});
this.bind('error', function(model, error) {
alert(error);
});
}
})
然后收集内我有这样的:
widgetsCollection: Backbone.Collection.extend({
model: mw.models.widgetsModel,
localStorage: new Store('widgets_'+mw.mainTab),
initialize: function(widget){
var $this = this;
_.bind('add', function(widget){
//console.log(widget.get('name'));
});
$('#dash_widget_container').sortable({
items:'.module_wrap',
accepts:'.module_wrap',
handle: '.module_header',
tolerance: 'pointer',
revert:true,
placeholder: "ui-state-highlight"
});
},
nextOrder: function() {
if (!this.length) return 1;
return this.last().get('order') + 1;
},
comparator: function(widgets) {
return widgets.get('order');
}
})
在这一点上我坚持。那里有任何想法?
