以下代码旨在作为可重用对象的简单构造的简短示例。这是一个非常简单的、一层深度的对象,放多少你喜欢的道具和方法,然后分配它们。
function someDesiredReusableType(optionally, pass, ctor, pars, here) {
//core obj to return
var DesiredTypeCrtor = {
propSkiingLocation: "canada",
OrderTickets: function(optionally){
var tryRoomWView = optionaly;
print(
"Dear " + ctor +", your request for " +
propSkiingLocation + " is now being processed: an " +
tryRoomWView + " request was notified, we understand you have " + pars + " for cross country transportation, confirmation email will be sent " + here + " as soon as we process your order. }
}
};
return DesiredTypeCrtor
}
这是此用法的示例:
var DesrVacSkC = someDesiredReusableType("could really help!",null, "mr. Bean", "my mini", "Fun@bbc.co.uk")
//oh..almost forgot
DesrVacSkC.OrderTickets();
作为这个富有想象力的对象,实际上并不像我在代码中使用的那么简单,它确实可以正常工作(没有尝试过这个实际的对象,因为它只是一个示例。)
但是下一个类似使用相同方法的设置有些错误。
这是一个对象的示例,我已经成功地在眨眼间实现了嵌套对象,使用与错误对象完全相同的方法,我不明白为什么他们在浏览器中应用了不同的方法。
//this is an important one, a smart property / value holder I came up with and does work perfectly, as a nested member.
function Rprp(parVal) {
var cretdprp = {
propVal: parVal,
propValAsint: parseInt(parVal)
};
return cretdprp;
}
但是下面的下一个没有,因为它缺少初始化的正确方法ownedFefCollCore
未捕获的类型错误:无法读取未定义的属性“HElmTColl”
//这是一个重要的,一开始是一个非常好的,将它添加到下面的对象中,直到我添加了ownedFefCollCore
成员。
function CreateFileEditForm_Manager() {
//as i do usually base/inner/creator and a return obj
var Repo = {
CsDataLocals:
{
GetCurLastfileId:Rprp($("#HLocModelData_LastFileId").val())
},
FormFldNames:
{ JRdrData_FileName: "JRdrData_FileName" },
//this is my bugg ! with and without new keyword & as function or Object!!
ownedFefCollCore: new FefCollCore(),
//and this is the line that chrome get's is anger on --> all day long
FeFDivWFldsColl: this.ownedFefCollCore.HElmTColl,
FeFDivWFlds_IdColl: this.ownedFefCollCore.HElmT_IdColl,
FeFDivWFldsCollAdd: function (parId, parFefDivWrpDivflds) {
this.ownedFefCollCore.CollAdd(parId, parFefDivWrpDivflds);
},
/ ........
//some more code was removed trying to keep it as short as possible
}
//fefa stands for fileRecord Edit Form , core just says nothing, is there to imply the 'thing' is to be shared between variation of instances from the base object
我在研究中发现了以下方法来减少容易出错的构造,但即使是这种方法也不能纠正错误。它是在其他一些东西中发现的,比如这个Object.create()
var FefCore = JClassProto({
initialize: function () {
this.HElmTColl = new Array();//was originally [] ...
//i changed because i wanted to eliminate any doubt that it's one of the reasons my code is ... Somewhere undefined , now i know (pretty sure they might be little different but both are ok.) it's not it.
this.HElmT_IdColl = new Array();
this.CollAdd = function (parId, parHElmT) {
this.HElmTColl.push(parHElmT);
this.HElmT_IdColl.push(parId);
}
this.Coll_Remove = function (parHElmT) {
this.HElmTColl.pop(parHElmT);
}
// this is the first move, if a new object(which is an element in the array) about to be created,
// call this to make sure not exist for i create do
this.ElmObjCanCreate = function (parId) {
return this.getIndexOfValuInDivWFldsColl(parId) < 0;
}
this.HElmTColl_FindById = function (parId) {
var collindexofCurFileReadyDivWrpFlds = this.getIndexOfValuInDivWFldsColl(parId);
return this.HElmTColl[collindexofCurFileReadyDivWrpFlds];
}
this.getIndexOfValuInHElmTColl = function (parId) {
return $.inArray(parId, this.HElmT_IdColl);
}
}
});
最后但并非最不重要的是,我的原始代码(在尝试将其创建为基本/共享对象之后)。
function FefCollCore() {
this.Cr = {
HElmTColl: new Array(),
HElmT_IdColl: new Array(),
CollAdd: function (parId, parHElmT) {
this.HElmTColl.push(parHElmT);
this.HElmT_IdColl.push(parId);
},
Coll_Remove: function (parHElmT) {
this.HElmTColl.pop(parHElmT);
},
CollNeedCreate: function (parId) {
return this.getIndexOfValuInDivWFldsColl(parId) < 0;
},
HElmTColl_FindById: function (parId) {
var collindexofCurFileReadyDivWrpFlds = this.getIndexOfValuInDivWFldsColl(parId);
return this.HElmTColl[collindexofCurFileReadyDivWrpFlds];
},
getIndexOfValuInHElmTColl: function (parId) {
return $.inArray(parId, this.HElmT_IdColl);
}
};
return this.Cr;
}
