var ready;
ready = function() {
var imageChooser, productChooser;
productChooser = function() {
var self;
self = this;
self.quantityId = ko.observable(1);
self.quantityText = ko.observable('QTY');
self.genderId = ko.observable(1);
self.sizeId = ko.observable(1);
self.colorId = ko.observable(1);
self.fullSize = ko.observable('SIZE');
this.setGenderAndSize = function(stringtoparse, thestring) {
var values;
values = stringtoparse.split(":");
self.fullSize("SIZE: " + thestring);
self.genderId(values[0]);
self.sizeId(values[1]);
};
this.setQuantity = function(quantity) {
self.quantityId(quantity);
self.quantityText("QTY: " + quantity);
};
};
imageChooser = function() {
this.clicked = ko.observable();
this.setBigImage = (function(message) {
alert(message);
}).bind(this);
};
ko.applyBindings(new productChooser(), $("#genderAndSizeChooser")[0]);
ko.cleanNode($('#genderAndSizeChooser')[0]);
return ko.applyBindings(new imageChooser(), $('#imageChooser')[0]);
};
$(document).on('ready page:load', ready);
我目前拥有此代码。不知何故,ko.cleanNode
代码:Uncaught TypeError:无法读取ko.cleanNode上未定义的属性'nodeType'
ko.cleanNode($('#genderAndSizeChooser')[0]);
产生一个错误:
Uncaught TypeError: Cannot read property 'nodeType' of undefined
人有一个想法错误的原因是什么?
你确定实际上有一个'genderAndSizeChooser'的'id'元素吗? 'ko.applyBindings'调用会收到未定义的,并像正常一样将绑定应用于主体,这样就不会出错,但在undefined上调用'ko.cleanNode'会导致错误。 – 2014-09-26 05:25:00
omg。请做出答案。 applyBindings的方式实际上不会发送任何错误。我的Rails应用程序已覆盖文档的“id” – 2014-09-26 06:01:58
