Buildgames returns rows:
<a>....</a>
<a>....</a>
When I click on each a the Buildcar_s function returns all the data inside an alert.
Instead of this alert I want to put all the results in a div under each a, so it would look like:
<a>.....clicked ...</a>
<div>....
...
</div>
<a>....not clicked...</a>
<a>....not clicked...</a>
<a>....not clicked...</a>
How can we put a div only under the a which was clicked?
function Buildcar_s(items) {
var div = $('<div/>');
$.each(items, function() {
var car_ = this.car_;
$('<a>' + this.car_ + '----' + this.Names + '---' + '</a>').click(function() {
_Services.invoke({
method: 'GetgamesRows',
data: {
car_Number: car_
},
success: function(car_s) {
var div = Buildgames(car_s);
$(div).insertAfter($a);
}
});
}).appendTo(div);
$('<br/>').appendTo(div);
});
$("#leftRows").append(div);
}
function Buildgames(items) {
var place = '<div>';
$.each(items, function() {
place += 'mmmmmm<br/>';
});
place += '</div>';
return place;
}
Try this, relevant changes have been commented:
function Buildcar_s(items) {
var div = $('<div/>');
$.each(items, function() {
var car_ = this.car_;
$('<a>' + this.car_ + '----' + this.Names + '---' + '</a>').click(function() {
var $a = this;
_Services.invoke({
method: 'GetgamesRows',
data: {
car_Number: car_
},
success: function(car_s) {
var div = Buildgames(car_s);
// this inserts the HTML generated from the function,
// under the A element which was clicked on.
$(div).insertAfter($a);
}
});
}).appendTo(div);
$('<br/>').appendTo(div);
});
$("#leftRows").append(div);
}
function Buildgames(items) {
var place = '<div>';
$.each(items, function() {
place += '<div style="float: right;"> ' + this.CITY + ' ' + '</div><BR />' + +'<br/><br/>';
});
place += '</div>';
return place; // returns the string created, as opposed to alerting it.

I Follow This Article for Impalement CRUD Operation with HTML5 and Javascript.
So that Submit Data to Local Storage and save it.
my problem is Delete and Edit Operation when clicking on delete and edit button Nothing happens.
Javascript
$(function () {
var operation = "A";
var selected_index = -1;
var tbClients = localStorage.getItem("tbClients"); //Retrieve the stored data
tbClients = JSON.parse(tbClients); //Converts string to object
if (tbClients === null) //If there is no data, initialize an empty array
tbClients = [];
function Add() {
debugger;
var Data = {
ExternalProjects: {
Name: $('#Name').val(),
Body: $('#Body').val(),
Url: $('#Url').val()
}
};
tbClients.push(Data);
localStorage.setItem("tbClients", JSON.stringify(tbClients));
alert("The data was saved.");
List();
return true;
}
function Edit() {
tbClients[selected_index] = JSON.stringify({
Name: $('#Name').val(),
Body: $('#Body').val(),
Url: $('#Url').val()
}); //Alter the selected item on the table
localStorage.setItem("tbClients", JSON.stringify(tbClients));
operation = "A"; //Return to default value
return true;
}
function List() {
debugger;
var div = $('div#ExProjectList');
div.html("");
var cli = tbClients;
for (var i = 0; i < cli.length; i++) {
debugger;
div.append(
'<div href="#" class="list-group-item list-group-item-action flex-column align-items-start">' +
'<div class="d-flex w-100 justify-content-between">' +
' <h5 class="mb-1">' + cli[i].ExternalProjects.Name + '</h5>' +
' <small>' +
'<a id="btnDelete" alt="Delete' + i + '"><i class="fa fa-trash" style="cursor: pointer" ></i></a>' +
'<a id="btnEdit" alt="Edite' + i + '"><i class="fa fa-pencil" style="cursor: pointer"></i></a>'
+ '</small>' +
' </div>' +
'<p class="mb-1">' + cli[i].ExternalProjects.Body + '</p>' +
'<small>' + cli[i].ExternalProjects.Url + '</small>' +
'</div>'
);
}
}
function Delete() {
tbClients.splice(selected_index, 1);
localStorage.setItem("tbClients", JSON.stringify(tbClients));
}
$('#btnDelete').bind('click', function() {
selected_index = parseInt($(this).attr("alt").replace("Delete", ""));
Delete();
List();
});
$("#btnEdit").bind("click", function() {
operation = "E";
selected_index = parseInt($(this).attr("alt").replace("Edit", ""));
var cli = JSON.parse(tbClients[selected_index]);
$("#Name").val(cli.ExternalProjects.Name);
$("#Body").val(cli.ExternalProjects.Body);
$("#Url").val(cli.ExternalProjects.Url);
});
$("#AddExternalProject").click(function () {
if (operation === "A"){
return Add();
}
else{
return Edit();
}
});
});
You are creating the HTML dynamically, but not attaching the event to the element.
Instead of using:
$('#btnDelete').bind('click', function() {
selected_index = parseInt($(this).attr("alt").replace("Delete", ""));
Delete();
List();
});
$("#btnEdit").bind("click", function() {
operation = "E";
selected_index = parseInt($(this).attr("alt").replace("Edit", ""));
var cli = JSON.parse(tbClients[selected_index]);
$("#Name").val(cli.ExternalProjects.Name);
$("#Body").val(cli.ExternalProjects.Body);
$("#Url").val(cli.ExternalProjects.Url);
});
Use event delegation:
$("#ExProjectList").on("click", "#btnDelete", function() {
selected_index = parseInt($(this).attr("alt").replace("Delete", ""));
Delete();
List();
});
$("#ExProjectList").on("click", "#btnEdit", function() {
operation = "E";
selected_index = parseInt($(this).attr("alt").replace("Edit", ""));
var cli = JSON.parse(tbClients[selected_index]);
$("#Name").val(cli.ExternalProjects.Name);
$("#Body").val(cli.ExternalProjects.Body);
$("#Url").val(cli.ExternalProjects.Url);
});
If you are binding any event to any html element, always bind inside
$(document).ready(function(){
//code here
});
Because if you add the script earlier before Dom Content is ready, in self calling function then those elements will not be available to bind the events.
I added a delete function to a todo list app that i built. The delete function works; however, when I refresh the page all the items that i deleted come back. How can I remove the items permanently from the database?

I'm trying to display RSS using the following JS code. But when I execute this, both the RSS feeds are changed to same content (the one that is execute later) and all the feeds are appended to the same div. I think rss = this is causing the problem. Any workaround ?
HTML:
<div id="rss1" class="rss-widget">
<ul></ul>
</div>
<div id="rss2" class="rss-widget">
<ul></ul>
</div>
<div id="rss3" class="rss-widget">
<ul></ul>
</div>
JS:
function RSSWidget(id, url) {
rss = this;
rss.FEED_URL = url;
rss.JSON = new Array();
rss.widgetHolder = $('#' + id + ' ul ');
rss.storiesLimit = 15;
rss.renderBlogItem = function (object) {
var item = '<li class="blog-item">';
item += '<a href="' + object.link + '">';
item += '<div class="blog-item-title">' + object.title + '</div>';
item += '<div class="blog-item-author">' + object.author + '</div>';
// item += '<div class="blog-item-content">' + object.content + '</div>';
item += '</a>'
item += '</li>';
rss.widgetHolder.append(item);
}
return $.ajax({
url: 'http://ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=10&callback=?&q=' + encodeURIComponent(rss.FEED_URL),
dataType: 'json',
success: function (data) {
if (data.responseData.feed && data.responseData.feed.entries) {
$.each(data.responseData.feed.entries, function (i, e) {
rss.JSON.push({ //add objects to the array
title: e.title,
author: e.author,
content: e.content || "",
link: e.link
});
});
if (rss.storiesLimit > rss.JSON.length)
rss.storiesLimit = rss.JSON.length;
for (var i = 0; i < rss.storiesLimit; i++) {
rss.renderBlogItem(rss.JSON[i]);
}
$('#' + id + ' li ').each(function () {
var delay = ($(this).index() / rss.storiesLimit) + 's';
$(this).css({
webkitAnimationDelay: delay,
mozAnimationDelay: delay,
animationDelay: delay
});
});
}
}
});
}
$.when(RSSWidget('rss1', "http://rss.cnn.com/rss/money_markets.rss"))
.then(function () {
RSSWidget('rss2', "http://feeds.reuters.com/reuters/financialsNews")
})
.then(function () {
RSSWidget('rss3', "http://finance.yahoo.com/rss/topfinstories")
});
.then(RSSWidget('rss2', "http://feeds.reuters.com/reuters/financialsNews"));
is immediately invoked. Try calling second RSSWidget within .then() anonymous function
.then(function() {
RSSWidget('rss2', "http://feeds.reuters.com/reuters/financialsNews")
})
Also, no promise is returned from RSSWidget; you can include return $.ajax(/* settings */) from RSSWidget to return the jQuery promise object from RSSWidget.

When I run the program it only reads one of the variables i.e. either 1 or 2.
How can I correct them to read both the variables?
Use this.
<script type="text/javascript">
window.onload = function() {
variable1.init();
variable2.init();
}
</script>
Try this
<body onload="callFunctions()">
JS-
function callFunctions()
{
variable1.init();
variable2.init();
}
Update-
Also
there are other different ways to call multiple functions on page load
Hope it hepls you.
I have a website which includes this RSS JavaScript. When I click feed, it opens same page, but I don't want to do that. How can I open with blank page? I have my current HTML and JavaScript below.
