I am trying to update the rows of the below html table dynamically based on the input received from ajax request made which returns a JSON object.
If i get more than one json object it becomes an issue to print it on the web page. I am looking at possible best solutions in this case to dynamically update my table using jQuery? For example If i get 10 objects I only want to show 5 and the rest maybe a next page link ? Can someone guide me what should i look into ?
jQuery Ajax
<script>
$.ajax({
url: 'http://localhost/getData/USSOUTH/',
async: false,
dataType: 'json',
success: function(data) {
for (var i in data) {
var USERNAME = data[i].USERNAME;
var EMAIL = data[i].EMAIL;
var PASSWORD = data[i].PASSWORD;
var ACTIVE = data[i].ACTIVE;
}
}
});
</script>
HTML BODY
<body>
<div class="wrapper">
<div class="table">
<div class="row header blue">
<div class="cell">
Username
</div>
<div class="cell">

i kinda simplified the code, but you'll get the gist and can modify it to apply with your specific code (and i cant do json with code snippet, so i simulated an array variable called jsonData)
$(document).ready(function() {
var jsonData = [
{ 'name': 'name2', 'email':'email2', 'content':'content2' },
{ 'name': 'name3', 'email':'email3', 'content':'content3' },
{ 'name': 'name4', 'email':'email4', 'content':'content4' },
{ 'name': 'name5', 'email':'email5', 'content':'content5' },
{ 'name': 'name6', 'email':'email6', 'content':'content6' },
{ 'name': 'name7', 'email':'email7', 'content':'content7' },
{ 'name': 'name8', 'email':'email8', 'content':'content8' }
];
$('.add').on('click', function() {
console.log('click');
var length = jsonData.length;
if (length > 5 ) { length = 5; } //limit to 5
for (var i = 0; i < length; i++) {
var clone = $('#template').clone(true).attr('id', '');
clone.find('.name').html(jsonData[i]['name']);
clone.find('.email').html(jsonData[i]['email']);
clone.find('.content').html(jsonData[i]['content']);
clone.appendTo('table');
}
});
});td {
border:1px solid black;
padding:2px;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<a href="#" class="add">add</a>
<table>
<tr id="template" class="dataRow">
<td class="name">Name1</td>
<td class="email">Email1</td>
<td class="content">Content1</td>
</tr>
</table>You can check the AJAX service documentation if it supports paging, which is its respond will contain only 5 records and an indicator that there is some more. That way you will be able to request next 5 records to display if needed in similar way as your first request.
If the service does not support paging then you may hide any record above first 5, with attribute style="display: none;" and display navigation links NEXT & PREVIOUS to "scroll" results.
// Data will be replaced with your Json call
var data = [
{'username': 'name1', 'email':'email1', 'password':'password1', 'active':'active1' },
{'username': 'name2', 'email':'email2', 'password':'password2', 'active':'active2' },
{'username': 'name3', 'email':'email3', 'password':'password3', 'active':'active3' },
{'username': 'name4', 'email':'email4', 'password':'password4', 'active':'active4' },
{'username': 'name5', 'email':'email5', 'password':'password5', 'active':'active5' },
{'username': 'name6', 'email':'email6', 'password':'password6', 'active':'active6' },
{'username': 'name7', 'email':'email7', 'password':'password7', 'active':'active7' },
{'username': 'name8', 'email':'email8', 'password':'password8', 'active':'active8' },
