Our jQuery tutorials are up to date and well explained step-by-step using live examples so you can learn jQuery fast and you can download scripts.
Once the web page is being fully loaded, then the same event handler is not being attached to newly created elements.
It seems like the event handler is being attached conceptually.
When you perform some action on new elements, then the event bind with it not trigger on the new element. But it is working on the elements which are created during the webpage loading.
This problem is common if the event handlers are not correctly attached.
If the form is already submitted and the user tries to refresh the webpage then the browser will attempt to resubmit the form.
If you are allowing the user to fill and submit the form for insert data. In this case, if the user refreshes the page then the data is reinserted into the MySQL database table if some action does not perform for preventing it.
In this tutorial, I show you some ways by using which you can avoid the page resubmit.
Whenever there is a large list of records that you are displaying in the HTML table. In this case, it’s better to allow the users to search text within the table.
You can easily do this on your Client-side with jQuery.
For searching text within HTML table columns I am using .contains() method.
In jQuery, there are various methods like – switchClass(), toggleClass(), addClass() and removeClass() by using them you can easily add or removes classes in the elements.
For using switchClass() method you need to include jQuery UI library within your page but you can simply use toggleClass(), addClass() and removeClass() without any dependency other than jQuery.
In this tutorial, I discuss about addClass() and removeClass() method.
