window.alert("success");
console.log("Retrieve success" + result);

function loadSQLQueryFailure(result){
WL.Logger.error("Retrieve failure");
}
You have a button in your HTML:
<input type="button" id="databasecon" value="click me to get data from db" />
You handle this button in wlCommonInit():
$('#databasecon').click(loadSQLRecords);
In loadSQLRecords() you call an adapter procedure to retrieve data from the database. If this operation succeeds then it calls the loadSQLQuerySuccess callback function.
It is this function that you are supposed to handle the display of the response from the backend (your database). But what are you doing? You only print to the console the response. You do not handle at all, displaying it in the application - in the HTML.
So in your HTML, you need to prepare a place holder that you will append the result into. For example: <table id="mytable"></table>
Then you need to populate the table with the data...
So in loadSQLQuerySuccess, you could for example do the following... this is where you need to learn HTML and JavaScript to accomplish what YOU want it to look like:
function loadFeedsSuccess(result) {
if (result.invocationResult.resultSet.length > 0)
displayFeeds(result.invocationResult.resultSet);
else
loadFeedsFailure();
}
function loadFeedsFailure() {
alert ("failure");
}
function displayFeeds(result) {
for (var i = 0; i < result.length; i++) {
$("#mytable").append("<tr><td>" + result[i].firstName + "</td></tr>");
$("#mytable").append("<tr><td>" + result[i].lastName + "</td></tr>");
}
}
Note that you need to create your own code in the for loop to make it look like how you want it to look, and of course append your own properties from the database, instead of "firstName" and "lastName".

How to configure bootstrap alerts in asp.net core razor pages.
<div class="alert alert-success">
<strong>Well done!</strong> You successfully read this important alert message.
</div>
As far as I know, if you want to show the alert, you could try to use jquery to achieve your requirement, you could add class in into the alert div. You could use ajax to call the razor page's onpost method and check the response if the response is true then you could alert success if not you could alert fail message.
More details, you could refer to below example codes:
#page
#model IndexModel
#{
ViewData["Title"] = "Home page";
}
#{
Layout = null;
}

success: function (response) {
if (response == "True") {
$("#buttonAlertSuccess").addClass('in');
} else {
$("#buttonAlertFail").addClass('in');
}
}
});
})
});
</script>
Post method:
public ActionResult OnPost() {
return new JsonResult("True");
}
Notice:
If you want to use ajax call ,you should set the CSRF-TOKEN settings in the startup.cs ConfigureServices method like below:
services.AddAntiforgery(o => o.HeaderName = "CSRF-TOKEN");

My adapter works fine but cant able to invoke in client side code. I have created a button and if I click it should display the database table.
Yes I have copied this code from other blog but modified here so need help.

I must say that this is quite sad. You copy the entire "implementation" from elsewhere, but do not copy the one thing that will finish it - displaying the data that is retrieved by the adapter. Then, you ask a question how to do it... I don't know what is your end goal with your project, but I don't think you'll get there if you will continue like this.
One way you could display the result is a function like this:
function displayFeeds(items){
var ul = $('#itemsList');
for (var i = 0; i < items.length; i++) {
var li = $('<li/>').html(items[i].sid);
li.append($('<li/>').html(items[i].sname));
li.append($('<li/>').html(items[i].sgrade));
li.append($('<hr>'));
ul.append(li);
}
}
This function assumes there is a UL in your HTML, and then appends LI's into it with items.
You will need to change this to fit your table design, as well as change sid, sname and sgrade with the correct property names from your database.
Next time you copy, at least copy everything: http://javatechig.com/ibm-worklight/invoking-adapter-procedure-in-ibm-worklight
I am very much new to AngularJS. I want to update the .less files variable dynamically. But didn't get how to access this .less file using AngularJS.
My code:
style.less
#bg-color: #484848;
.header{
background: #bg-color;
}
I want to update #bg-color: #484848; present in the style.less file to some value input by user. How can I get this using AngularJS.
You should run Less in browser to do this. If you load less.js in your HTML, the global less object come available, so you can use less.modifyVars() and less.refreshStyles() inside your angularJS code:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Example - example-example78-production</title>
<link rel="stylesheet/less" type="text/css" href="color.less" />
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.0-beta.1/angular.min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/less.js/2.3.1/less.min.js"></script>
</head>
<body ng-app="submitExample">
<script>
angular.module('submitExample', [])
.controller('ExampleController', ['$scope', function($scope) {
$scope.list = [];
$scope.text = 'orange';
$scope.submit = function() {
if ($scope.text) {
less.modifyVars({ color : $scope.text });
}
};
}]);
</script>
<h1>Colored text</h1>
<form ng-submit="submit()" ng-controller="ExampleController">

I am using Visual studio 2012 to create a sample Windows 8 Phone app.
From the "Create New Project" option I have selected,
Windows > Windows Phone HTML5 App
I have also added a jquery.min.js file to the project as shown below.
Below is my code written in index.html...
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<link rel="stylesheet" type="text/css" href="/html/css/phone.css" />
<script type="text/javascript" src="/html/js/jquery.min.js" ></script>
<title>Windows Phone</title>
<script type="text/javascript">
$("#dynamic-box").text("hey !");
</script>
</head>
<body>
<div>
<p>MY APPLICATION</p>
</div>
<div id="dynamic-box"></div>
</body>
</html>
But no matter what I try my jquery code just wont work. Is there some other way in which jquery is to be written in Windows 8 Phone app ?
Please help me on this.
Two things going on here, one jQuery, one Windows Phone:
Put your code into the ready event (it won't work in a web page either as is)
<script type="text/javascript">
$(document).ready(function () {
$("#dynamic-box").text("hey!");
});
</script>
Set IsScriptEnabled BEFORE navigating to the opening page. Flip the order of the statements in Browser_Loaded in MainPage.xaml.cs.
private void Browser_Loaded(object sender, RoutedEventArgs e)
{
// Add your URL here
Browser.IsScriptEnabled = true;
Browser.Navigate(new Uri(MainUri, UriKind.Relative));
}
I recently wrote a post on this, thought it be useful to share it here...
Step 1 : Add jquery.min.js to the solution
Step 2 : Change the order of statement in Browser_Loaded method as shown below
private void Browser_Loaded(object sender, RoutedEventArgs e)
{
// Add your URL here
Browser.IsScriptEnabled = true;
Browser.Navigate(new Uri(MainUri, UriKind.Relative));
}
Step 3: Sample Jquery code
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<link rel="stylesheet" type="text/css" href="/html/css/phone.css" />
<script type="text/javascript" src="/html/js/jquery.min.js" ></script>
<title>Windows Phone</title>
<script type="text/javascript">
$(document).ready(function () {
$("#message").text("Welcome !");
$("#goBtn").click(function(){
$("#message").text("button has been pressed");
});
});
</script>
</head>
<body>
<div>
<p>MY APPLICATION</p>
</div>
<div id="message"></div>
<input type="button" id="goBtn" value="press me !" />
</body>
</html>

I have downloaded dojo build, now I have an doubt, in the below example code, I am using "dojo.js.uncompressed.js" as a start of source file, is it right? Just I want to display a button in the web page. Which one is the start file? in dojo library.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html dir="ltr">
<head>
<style type="text/css">
body, html { font-family:helvetica,arial,sans-serif; font-size:90%; }
</style>
<script src="../dojo/lib/dojo/dojo.js.uncompressed.js"
djConfig="parseOnLoad: true">
</script>
<script type="text/javascript">
dojo.require("dijit.form.Button");
dojo.addOnLoad(function() {
// Create a button programmatically:
var button = new dijit.form.Button({
label: "Click me!",
onClick: function() {
// Do something:
dojo.byId("result1").innerHTML += "Thank you! ";
}
},
"progButtonNode");
});
</script>
<link rel="stylesheet" type="text/css" href="../dojo/lib/dijit/themes/claro/claro.css" />
</head>
<body class=" claro ">
<button id="progButtonNode" type="button">
</button>
<div id="result1">
</div>
<!-- NOTE: the following script tag is not intended for usage in real
world!! it is part of the CodeGlass and you should just remove it when
you use the code -->
<script type="text/javascript">
dojo.addOnLoad(function() {
if (document.pub) {
document.pub();
}
});
</script>
</body>
</html>
dojo (and any js file) should be put next to your html files so that it is served by the server. Then you don't have to relate to long relative paths
