我有两个阵列敲除selectedSocialNetworks和List_2的所有该列表可以包含一个社交网络（Twitter或Facebook）或二者（Twitter和Facebook）阵列中敲除
<script id="socNetchoiceTmpl" type="text/html">
<ul data-bind="foreach: socialNetworksList, visible: socialNetworksList().length > 0">
<li>
<input type="checkbox" data-bind="value: $data, checked:
$parent.selectedSocialNetworks" /><span data-bind="text: $data"/>
</li>
</ul>
function SocialNetChoicesViewModel() {
var self = this;
self.socialNetworksList = ko.observableArray([]);
self.selectedSocialNetworks = ko.observableArray([]);
self.List_2 = ko.observableArray([]);
self.save = function() {
if(....){
$.ajax("/Home/SocialNetworksChoice", {
data: ko.toJSON({ selectedSocialNetworks: self.selectedSocialNetworks }),
type: "post", contentType: "application/json",
success: function (result) {
if (result.Success) {
//alert(result.Message);
}
else {
alert(result.Message);
}
}
});
}
else{
$.ajax("/Home/Authentification", {
data: ko.toJSON({ socialNetworks: self.List_2 }),
type: "post", contentType: "application/json",
success: function (result) {
if (result.Success) {
//alert(result.Message);
}
else {
alert(result.Message);
}
}
});
}
};
// Load initial state from server, convert it to Task instances,
// then populate self.tasks
$.getJSON("/Home/SocialNetworksChoice", function (allData) {
var mappedItems = $.map(allData, function (item) { return item });
self.socialNetworksList(mappedItems);
});
$.getJSON("/Home/Authentification", function (allData) {
var mappedItems = $.map(allData, function (item) { return item });
self.List_2(mappedItems);
});
};
我想检测希望社交网络不包含在我的List_2中，并且它在所选社交网络中
我使用if比else检测List_2 = selectedSocialNetworks是否执行指令如果...
对不起我的英文不好，
感谢，
你能提供一个输入和输出的例子。这很难理解。 – Tyrsius 2012-08-08 20:00:14

这真是一个JavaScript问题。见http://stackoverflow.com/questions/237104/array-containsobj-in-javascript – 2012-08-10 15:19:26
