I have a simple form in meteor which would help configure the execution of my custom application.
This form receives two arguments, Username and Password.
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Execute my custom app</title>
</head>
<body>
{{> configDetails}}
</body>
<template name="configDetails">
<div class="container">
<form class="form-signin" role="form" id="form-signin" >
<div class="row">
<div class="span3 offset"><input type="textBox" class="input-block-level" placeholder="User Name" ></div>
<div class="span3 offset1"><input type="textBox" class="input-block-level" placeholder="Password" ></div>
</div>
<input class="btn btn-lg btn-primary" type="submit" style="display: block; width: 100%;" id="submit"/>
</form>
</div>
</template>
Now I want these values to be received on the server side so that I can run my external app using child_process and pass these values as arguments to the external app. How can I receive these value in the meteor server section:
if (Meteor.isServer) {
//I intend to use child_process to run my external application here
}
If the values cannot directly be received in the server section, how can I receive them in client section and pass them onto server. I am having difficulties receiving them in client section as well:
if (Meteor.isClient) {
Template.configDetails.events({
'click input': function () {
console.log( 'Submitting form!' );
// template data, if any, is available in 'this'
if (typeof console !== 'undefined')
console.log("You pressed the button");
}
});
Template.configDetails.events({
'submit form': function( event ){
console.log( 'Submitting form!' );
event.preventDefault();
event.stopPropagation();
return false;
}
});
None of the above functions execute the console.log method. Any ideas what I am doing wrong. Let me know if you need further info.
In my projets I'm using smth like this:
Template.configDetails.events({
"click #submit": function(e, t) {
e.preventDefault();
Meteor.call('someMethod', attributes, function(error, id) {
if (error) {
return console.log("Error..........");
} else {
//Do smth
}
});
});
}
});

Am trying to create a CRUD operation using phonegap/cordova, and I keep receiving "Uncaught DOMException: An attempt was made to break through the security policy of the user agent. at window.onload - Line 17" pointing to =>"db = window.openDatabase("employee", "1.1", "LearnToProgram", 200000);". This further affects db.transaction Line 25 “Uncaught TypeError: Cannot read property 'transaction' of undefined”, because Database was not created. Do I need any SQLLite plugin on maybe there is something else missing?

To open a database:
var db = null;
document.addEventListener('deviceready', function() {
db = window.sqlitePlugin.openDatabase({
name: 'my.db',
location: 'default',
});
});
IMPORTANT: Like with the other Cordova/phonegap plugins your application must wait for the deviceready event. This is especially tricky in Angular/ngCordova/Ionic controller/factory/service callbacks which may be triggered before the deviceready event is fired.
I want to make an client Windows Application using java script by make my Windows Application as webBrowser1 (same idea of PhoneGap). I write html page that contains SignalR javascript code with necessary src.
This is the code in Windows Application:
webBrowser1.Url = new Uri(#"D:\Signal.html");
This is the src in Signal.html:

I think it's a CORS problem.
Your signalR client is in D:\SignalR.html
Your signalR server is in http://localhost:5539/signalr/hubs
meaning that it is a Cross Origin signalR calls. You need to enable CORS in order to let it works.
Upon submission of a form, I want to push that data to my Firebase db and so I'm creating a function to do so (addMeeting). However, upon pressing the button to submit I get the error:
TypeError: undefined is not a function
at l.$scope.addMeeting (http://localhost:8000/js/controllers/meetings.js:10:12)
meetings.js:10:12 is right where my $push is if you'll look at my code below.

**Edit: ** It has something to do with the .push() method itself. I see that in the latest version of angularfire/firebase it should be .push, instead of .$push, ad have changed that but it does not solve my problem. I reverted AngularFire and Firebase to versions 0.8.2 and 1.0.21 respectively, re-introduced the .asObject() and $push, and everything works fine. I don't understand why .push() is failing with all the latest (Firebase 2.2.2, AngularFire 1.0).
Firebase's AngularFire library has two primary types: $firebaseObject and $firebaseArray (instantiated through $asObject and $asArray respectively in pre-1.0 versions of AngularFire).
You're using both the wrong type and the wrong method. To quote AngularFire's documentation on its array type:
Synchronized arrays should be used for any list of objects that will be sorted, iterated, and which have unique IDs. The synchronized array assumes that items are added using $add(), and that they will therefore be keyed using Firebase push IDs.
So:
var ref = new Firebase('https://angulardataldc.firebaseio.com/meetings');
var meetings = $firebaseArray(ref);
$scope.meetings = meetings;
$scope.addMeeting = function() {
meetings.$add({
name: $scope.meetingname,
date: Firebase.ServerValue.TIMESTAMP
})
}
You made a typo, it should be .push instead of $push
CODE
$scope.addMeeting = function() {
meetings.push({
name: $scope.meetingname,
date: Firebase.ServerValue.TIMESTAMP
})
}

In below ExamppleController function a value is entered into message variable local storage. For the first time value is getting stored but when entered again value is not getting stored. When browser cache is cleared then value is stored again and second time no value is getting stored.

You should really be doing things the AngularJS way. I think this is where the disconnect happens.
See the following code:
<html>
<head>
<script src="angular.min.js"></script>
<script src="ngStorage.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-router/0.2.13/angular-ui-router.min.js"></script>
<script>
var example = angular.module("example", ["ngStorage", "ui.router"]);
example.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('1', {
url: '/1',
templateUrl: 'templates/1.html',
controller: 'FirstController'
})
.state('2', {
url: '/2',
templateUrl: 'templates/2.html',
controller: 'SecondController'
});
$urlRouterProvider.otherwise('/1');
});
example.controller("FirstController", function($scope,$localStorage,$location) {
$scope.save = function() {
$localStorage.message = $scope.name;
$location.path("/2");
}
});
example.controller("SecondController", function($scope,$localStorage,$location) {
$scope.data1 = $localStorage.message;
});
</script>
</head>
<body ng-app="example">
<div ui-view></div>
<script id="templates/1.html" type="text/ng-template">
<div>
<input type="text" ng-model="name"/>
<button ng-click="save()">Save</button>
<br>
</div>
</script>
<script id="templates/2.html" type="text/ng-template">
<div>
<span>{{data1}}</span>
</div>
</script>
</body>
</html>
You'll notice I'm using routes and navigating between them using the $location provider. The $localStorage works fine when doing it this way.
Read up on the ui-router or ngRoute.
Regards,
I currently use button and trying to launch a new window passing parameter from mypage to the new page like this
<input type="button" name="launchpg" id="launchpg" value="LaunchPage" onclick="launch_page('<%=list_process_url%>',this.form.myform.options[this.form.myform.options.selectedIndex].value);"/>
Javascript is as below:
<script type="text/javascript">
//call servlet
function launch_new_window(list_process_url,smart_id)
{
popupWindow = window.open(list_process_url+"&id="+id,'List Process Page',
'scrollbars = yes');
}
I am trying to replace button with href link as in..
document.location='main.jsp?PAGE=myPage.jsp&id='+this.form.myform.options[this.form.myfom.options.selectedIndex].value;
I would like to use the same javascript for launching a new window passing the parameter to the script function.
The code however doesn't seem to work as it says Form is not valid for href.
Add this to wherever you want to launch a new page from:
window.location.href = "pageName.html";
<head>
<title></title>
<script src="Scripts/jquery-2.1.1.min.js"></script>
</head>
<body>
<div id="main">
<script>
$(function () {
<!--Some Logic-->
<!--window.location.href = "NewWindowName.html";-->
}
$("#btnSave").click(function () {
openNewWindow();
});
function openNewWindow()
{
window.location.href = "NewWindowName.html";
}
});
</script>
<article>
<button id="btnSave">Save Data</button>
</article>
</div>
</body>
I found a solution to my question:
Open New Window
