I am actually creating the table dynamically , adding rows like this
markup = "<tr onclick="+"getDetails(this)"+"><td>" + col1value+ "</td><td>" + col2value+ "</td></tr>";
$("#MyTableID tbody").append(markup);
now i created a table row click which is below , making remove button visible
function getDetails(row) {
$('#buttonRemove').css('visibility', 'visible');
}
Now i have to add a css class to the row clicked and also when button remove is clicked the selected row should be removed
how to write that.
Also i have to check another this in my remove button click function that is there any row present in table or not - how to put that logic
To toggle class on dynamic tr
click use .toggleClass
:
// Always bind 'on' to static element
$(document).on('click', '#MyTableID tbody tr', function () {
$(this).toggleClass('classToToggle');
// For more classes: .toggle('class1 class2'); - will remove what exists and add what is missing
// For more precise toggling: .toggle('classN', trueIfToAdd)
});
To check if table has any rows:
if ($('#MyTableID tbody tr').length) {
alert('there is rows added');
} else {
alert('No rows added');
}
function getDetails(el) { $(el).toggleClass('active'); console.log('Rows count: '+$('#MyTableID tbody tr').length); } function removeRow(el) { $(el).closest('tr').remove(); } function addRow() { $('#MyTableID tbody').append( "<tr onclick='getDetails(this)'><td>" + Math.ceil(Math.random() * 10) + "</td><td>" + Math.ceil(Math.random() * 10) + "</td><td><button onClick='removeRow(this)'>Remove</button></td></tr>" ); }
table { width: 100%; table-layout: fixed; } table .active { background-color: black; color: white; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <table id="MyTableID"> <thead><th>Val 1</th><th>Val 2</th><th>Remove</th></thead> <tbody></tbody> </table> <hr/> <button onClick="addRow()">Add row</button>
The following code changes the look and feel of the table by changing its class, it is achieved by AngularJS:

By using AngularJS you can change the attributes of the DOM elements on the same page(that is without reloading the page). Hope this will help you :)
