I have this HTML:
<ul class="chat_list" data-bind="foreach: chats">
<li>
<div class="chat_response" data-bind="visible: CommentList().length == 0">
<form data-bind="submit: $root.addComment">
<input class="comment_field" placeholder="Comment…"
data-bind="value: NewCommentText"
/>
</form>
</div>
</li>
</ul>
and this JavaScript:
function ChatListViewModel(chats) {
// var self = this;
self.chats = ko.observableArray(ko.utils.arrayMap(chats, function (chat) {
return { CourseItemDescription: chat.CourseItemDescription,
CommentList: ko.observableArray(chat.CommentList),
CourseItemID: chat.CourseItemID,
UserName: chat.UserName,
ChatGroupNumber: chat.ChatGroupNumber,
ChatCount: chat.ChatCount,
NewCommentText: ko.observable("")
};
}));
self.newChatText = ko.observable();
self.addComment = function (chat) {
var newComment = { CourseItemDescription: chat.NewCommentText(),
ParentCourseItemID: chat.CourseItemID,
CourseID: $.CourseLogic.dataitem.CourseID,
AccountID: $.CourseLogic.dataitem.AccountID,
SystemObjectID: $.CourseLogic.dataitem.CommentSystemObjectID,
SystemObjectName: "Comments",
UserName: chat.UserName
};
chat.CommentList.push(newComment);
chat.NewCommentText("");
};
}
ko.applyBindings(new ChatListViewModel(initialData));
When I go into the debugger it shows that the chat parameter of the addComment() function is a form element instead of a chat object.
Why is this happening?
