How i can edit in here? last time i did, and it made new post...
BTW, i apply it like this:
HTML:
<div class="message" data-ng-repeat="x in ChatModel.Messages">
JS:
var MessageList = function () { //Type Message
this.values = [];
this.push=function(username, message){
this.values.push({UserName: username, Message: message});
return;//throw exception
};
this.get=function(index) {
return this.values[index];
}
this.toArray = function ()
{
return angular.copy(this.values);
}
}
var groupMessages = new MessageList();
$scope.ChatModel = {
Logged: false,
Message: '',
Login: {
UserName: '',
UserId: ''
},
Messages: groupMessages.values//UserName, Message
};
$scope.AddMessage = function (userName, message) {
//$scope.ChatModel.Messages.
groupMessages.push(userName, message);
var divChatWindows = angular.element('#divChatWindow');
$scope.$apply();///////////////////////////////////////////////////////////////////////////////////////////////////
//-var divNewMessage = '<div class="message"><span
class="userName">' + userName + '</span>: ' + message + '</div>';
//-angular.element(divNewMessage).appendTo(divChatWindows);
var height = divChatWindows[0].scrollHeight;
divChatWindows.scrollTop(height);
}
now, even with $apply, i'm one row late (sorry for bad language). i had,
but not already use jquery, but angular stuff, like angular.element, etc...
and what should i do with id? and does it matter if js find element by id
which is globally known, or by something else?
