I have one problem which is related to saving records from edit mode. Scenario:
1. Click on edit (first records), it will load selected model data in edit mode panel.
2. Update any value in textbox
3. Click on save, it will save successfully and refresh view.
4. Click on edit (second records(, it will load selected model data in edit panel.
5. Update any value in textbox
Click on save, it will save successfully and refresh view But the problem is It will replace updated model value with Row1 and Row2. I would like to update only selected row. What was wrong in this code.
window.App = { Models: {}, Collections: {}, Views: {}, Helper: {} }
App.Helper.getFormsValue = function (form) {
var newName = form.find('.name').val();
var newAge = form.find('.age').val();
var newOccupation = form.find('.occupation').val();
return { name: newName, age: newAge, occupation: newOccupation };
}
Model and Collection
App.Models.Person = Backbone.Model.extend({
defaults: { name: '', age: 0, occupation: '' }
});
App.Collections.People = Backbone.Collection.extend({
model: App.Models.Person
});
Add Person
App.Views.AddPerson = Backbone.View.extend({
el: '#addPersonWrapper',
events: {
'click .add': 'addPersonForm',
'click .save': 'addPerson'
},
addPersonForm: function (e) {
$(e.target).hide();
this.$el.find('.addPerson').show();
},
addPerson: function () {
var form = this.$el;
form.find('.addPerson').hide();
form.find('.add').show();
var person = new App.Models.Person(App.Helper.getFormsValue(form));
this.collection.add(person);
}
});
Edit Person
App.Views.EditPerson = Backbone.View.extend({
el: '.editPersonWrapper',
template: template.get('editTemplate'),
initialize: function () {
this.$el.show();
this.rentder();
},
events: {
'click .save': 'savePerson'
},
rentder: function () {
this.$el.html(this.template(this.model.toJSON()));
},
savePerson: function () {
console.log(this.model.toJSON());
var form = this.$el;
this.model.set(App.Helper.getFormsValue(form));
this.$el.hide();
}
});
Person View
App.Views.Person = Backbone.View.extend({
tagName: 'tr',
template: template.get('listTemplate'),
initialize: function () {
this.model.on("change", this.render, this);
this.model.on('destroy', this.remove, this);
this.on("edit", function (view) {
var editperson = new App.Views.EditPerson({ model: view.model });
}.bind(this));
},
events: {
'click .edit': 'editPerson',
'click .delete': 'deletePerson'
},
render: function () {
this.$el.html(this.template(this.model.toJSON()));
return this;
},
editPerson: function () {
this.trigger("edit", this);
},
deletePerson: function (e) {
this.model.destroy();
},
remove: function () {
this.$el.remove();
}
});
People View
App.Views.People = Backbone.View.extend({
el: '#personList',
initialize: function () {
this.collection.on("add", this.addPerson, this);
this.render();
},
render: function () {
this.collection.each(this.addPerson, this);
},
addPerson: function (person) {
var personView = new App.Views.Person({ model: person });
this.$el.append(personView.render().el);
}
});
Default Data
var peopleCollection = new App.Collections.People([
{ name: 'Imdadhusen', age: 31, occupation: 'M.C.A.' },
{ name: 'Manindar', age: 27, occupation: 'B.E.I.T.' },
{ name: 'Kuber', age: 32, occupation: 'M.S.C.I.T.' },
{ name: 'Rashidali', age: 5, occupation: 'S.K.G' }]);
var addPerson = new App.Views.AddPerson({ collection: peopleCollection });
var peopleView = new App.Views.People({ collection: peopleCollection });
