[英]knockout with require js - Not loading correctly
大家好,我在使用require js和敲除js時遇到一些困難。 我正在嘗試將require js實施到我正在進行的現有項目中。 一切都進行得很好,直到我被淘汰賽打倒。
我正在嘗試遵循此處的剔除頁面上提供的示例: http : //knockoutjs.com/documentation/amd-loading.html
當嘗試ko.applyBindings(new GDI_Application());
它只是返回未定義。 Ive還設置了https://github.com/rniemeyer/knockout-amd-helpers來加載外部模板。 在這里遵循了另一指南http://www.newsuntold.dk/post/using-requirejs-and-knockout-amd-helpers-with-knockout,但仍然有一定的區別,仍然會引起Uncaught TypeError: undefined is not a function
你們覺得我失蹤了什么?
更新的代碼:我的HTML代碼:
<script data-main="js/GDI_MAIN" src="js/require.js"></script>
這是我的GDI_MAIN js代碼:
require.config({
paths: {
"jqueryUI": "../assets/jqueryUI/jquery-ui.min",
"bootstrap": "bootstrap.min",
"bootstrap_select": "../assets/silviomoreto-bootstrap-select-a8ed49e/dist/js/bootstrap-select.min",
"jquery_timepicker": "jquery-ui-timepicker-addon",
"jqueryui_timepicker_ext": "jquery-ui-sliderAccess",
"moment": "moment",
"cookie": "js.cookie",
"knockout-amd-helpers": "knockout-amd-helpers.min",
"text": "text"
},
"shim": {
bootstrap: {
deps : [ 'jquery'],
exports: 'Bootstrap'
},
bootstrap_select: {
deps : [ 'jquery', 'bootstrap'],
exports: 'Bootstrap_Select'
},
jquery_timepicker: {
deps : [ 'jquery'],
exports: 'Jquery_Timepicker'
},
jqueryui_timepicker_ext: {
deps : [ 'jquery'],
exports: 'Jqueryui_Timepicker_Ext'
}
}
});
require(["knockout", "GDI_Application", "GDI_Buttons", "GDI_common", "knockout-amd-helpers", "text", "moment"], function (ko, GDI_Application) {
ko.amdTemplateEngine.defaultPath = "../templates";
ko.applyBindings(new GDI_Application());
GDI_Application.fetchdata();
});
這是GDI_Application代碼:
define(["knockout", "jquery", "jqueryUI", "bootstrap", "bootstrap_select","jquery_timepicker", "jqueryui_timepicker_ext", "moment"], function(ko, $) {
ko.bindingHandlers.modal = {
init: function (element, valueAccessor) {
$(element).modal({
show: false
});
var value = valueAccessor();
if (typeof value === 'function') {
$(element).on('hide.bs.modal', function() {
value(false);
});
}
ko.utils.domNodeDisposal.addDisposeCallback(element, function () {
$(element).modal("destroy");
});
},
update: function (element, valueAccessor) {
var value = valueAccessor();
if (ko.utils.unwrapObservable(value)) {
$(element).modal('show');
} else {
$(element).modal('hide');
}
}
}
incidentViewModel = function IncidentViewModel() {
var self = this;
self.showDialog = ko.observable(false);
self.incidents = ko.observableArray();
self.currentIncident = ko.observable();
Incident.BASE_URL = '../../_vti_bin/listData.svc/GDI_DEV_Incidents';
Incident.CREATE_HEADERS = {"accept": "application/json;odata=verbose"};
Incident.UPDATE_HEADERS = {"accept": "application/json;odata=verbose","If-Match": "*"};
self.fetchdata = function() {
console.log("fetching - Attempting to execute code.");
$.getJSON(Incident.BASE_URL+filterlist+orderlist,
function(data) {
if (data.d.results) {
self.incidents(data.d.results.map(function(item) {
return new Incident(item);
}));
$('#loading').hide("slow");
$('#IncidentTable').show("slow");
console.log("fetching data completed");
}else {
console.log("no results received from server");
}
});
}
self.saveorupdate = function() {
console.log("save function executed");
var id = this.ID,
url = Incident.BASE_URL + (id ? '(' + encodeURIComponent(id) + ')' : '');
console.log(url);
return $.ajax(url, {
type: id ? "MERGE" : "POST",
data: ko.toJSON({
Description: this.Description,
Incident: this.Incident
}),
processData: false,
contentType: "application/json;odata=verbose",
headers: id ? Incident.UPDATE_HEADERS : Incident.CREATE_HEADERS,
success: function (data) {
incidentViewModel.fetchdata();
console.log("Record was sucessfully saved.");
}
});
}
self.ShowSelectedIncident = function(data) {
self.currentIncident(data);
self.showDialog(true);
console.log("The show selected incident has been ran.");
}
self.clearCurrentIncident = function() {
self.showDialog(false);
self.currentIncident(null);
}
self.AddNewIncident = function() {
self.showDialog(true);
self.currentIncident({ID:"",Description:"",Incident:""});
console.log("AddNewIncident has been executed sucessfully.");
}
}
function Incident(data) {
var self = this;
self.ID = data.ID;
self.Description = ko.observable(data.Description);
self.Composante = ko.observable(data.Composante);
self.Incident = ko.observable(data.Incident);
self.ÉtatValue = ko.observable(data.ÉtatValue);
self.PrioritéValue = ko.observable(data.PrioritéValue);
self.Duré = ko.observable(data.Duré);
self.Service = ko.observable(data.Service);
self.Début_imputabilité = ko.observable(data.Début_imputabilité);
self.Début_de_interruption = ko.observable(data.Début_de_interruption);
self.Fin_de_interruption = ko.observable(data.Fin_de_interruption);
self.Groupe_Support_Prime = ko.observable(data.Groupe_Support_Prime);
self.ResponsableValue = ko.observable(data.ResponsableValue);
self.Impact = ko.observable(data.Impact);
self.Dépanage = ko.observable(data.Dépanage);
self.Suivi = ko.observable(data.Suivi);
self.Ressources = ko.observable(data.Ressources);
}
return incidentViewModel;
});
讓我煩惱的是:GDI_Application當前未返回任何內容。
看起來IncidentViewModel是您的應用程序ViewModel,因此您需要從GDI_Application代碼返回IncidentViewModel,以便KO具有將綁定應用到其中的內容。
var incidentViewModel = function IncidentViewModel() {
// your code here;
}
//later on
return incidentViewModel;
正如您指出的那樣,對GDI_Application.fetchdata()的調用將不起作用。 與您使用完全不同的方法時相比,這一定會帶來一些困擾。
你可以做
var app = new GDI_Application();
ko.applyBindings(app);
app.fetchdata();
另外,我會考慮將GDI_Application重命名為IncidentViewModel,因為這就是事實。
不能直接回答我所知道的問題,但是我為.NET生態系統開發了一個模板,該模板使用組件體系結構將RequireJS與KnockoutJS結合在一起,並且將NancyFX引入其中以用於.NET MVC,例如操作和視圖以及包括Bootstrap和jQuery支持。
您可以從我的git hub帳戶下載它:
https://github.com/shawty/dotnetnotts15
它使用Knockout組件和自定義標簽,允許模塊化代碼重用,即使已為NancyFX連接,它也只是標准的ASP.NET Web應用程序,因此您可以輕松刪除Nancy並重新添加ASP.NET MVC,甚至可以使用任何您選擇的后端。
