Open App.JS, delete all previous code of this file.
Add following code:
(function () {
var appURL = GetUrlKeyValue("SPAppWebUrl");
jQuery(function () {
var message = jQuery("#message");
});
function failHandler(jqXHR, testStatus, errorThrown) {
var response = "";
try {
var parsed = JSON.parse(jqXHR.responseText);
response = parsed.error.message.value;
} catch (e) {
response = jqXHR.responseText;
}
alert("Call failed. Error: " + response);
}
})();
Now i am going to use a little trick here, I am going to use the Repository js file of Pluralsight, I am very thankful to Rob Windsor for this:
repositories.js (7.54 kb)
Add this js file under Script Folder in your solution:
Add repositories.js file to _references.js for get intellisense :
Add this js file also on the default.aspx page:
Save your project.
Deploy this SharePoint Hosted App and Enjoy.......
