以下爲對象的樣本結構：KnockoutJS添加，編輯，刪除
[{
MasterType: "mtype1",
Types: [{
TypeStage: "st1",
TypeDate: "12/02/2001",
SubTypes: [{
SubTypeData: "st1"
}, {
AnotherData: "ad1"
}]
}, {
TypeStage: "st3",
TypeDate: "15/02/2001",
SubTypes: [{
SubTypeData: "st3"
}, {
AnotherData: "ad3"
}]
}]
},
{
MasterType: "mtype2",
Types: [{
TypeStage: "st2",
TypeDate: "12/04/2001",
SubTypes: [{
SubTypeData: "st2"
}, {
AnotherData: "ad2"
}]
}]
}];
注：在頁面加載，對象是空的。
我需要顯示每個行的編輯/刪除的MasterType表。 我也需要一個「添加」按鈕，然後隱藏表格並顯示輸入字段以輸入新的MasterType的值。 保存新的MasterType後，我需要隱藏輸入字段並再次顯示錶格。
請幫
我也做了以下內容：
<table>
<tbody data-bind="foreach: MasterTypes">
<tr><td data-bind='text: MasterType'></td></tr>
</tbody>
</table>
<div >
<table>
<tbody data-bind="foreach: MasterTypes">
<tr>
<td>
<input data-bind="value: MasterType,valueUpdate: 'afterkeydown'" />
<div><a href='#' data-bind='click: $root.removeMasterType'>Delete</a></div>
</td>
<td>
<table>
<tbody data-bind="foreach: Types">
<tr>
<td><input data-bind='value: TypeStage' /></td>
<td><input data-bind='value: TypeDate' /></td>
<td><a href='#' data-bind='click: $root.removeType'>Delete</a></td>
<td>
<table>
<tbody data-bind="foreach: SubTypes">
<tr>
<td><input data-bind='value: Discharge' /></td>
<td><a href='#' data-bind='click: $root.removeSubType'>Delete</a></td>
</tr>
</tbody>
</table>
<a href='#' data-bind='click: $root.addSubType'>Add New Sub type</a>

</tbody>
</table>
<a href='#' data-bind='click: $root.addType'>Add new Type</a>
</td>
</tr>
</tbody>
</table>
</div>
<p>
<button data-bind='click: addMasterType'>Add New MasterType</button>
<button data-bind='click: save, enable: MasterTypes().length > 0'>Save to JSON</button>
</p>
<textarea data-bind='value: lastSavedJson' rows='5' cols='60' disabled='disabled'> </textarea>
<script type="text/javascript">
var MasterTypesModel = function (mastertypes) {
var self = this;
self.tableVisible = ko.observable(true);

self.addMasterType = function() {

你還做了什麼？ – Damien
