Example 2 (Searching Text) Php Page Name: jquery_search.php:

});
< /script>
< /head>
< body>
< form name=”frm” action=”” method=”post”>
< table border=”0″ id=”searchoption” align=”left”

Searching text is a good example for helping in searching of the name, address, and other details pf a user with simple typing the text which you want to be search.

If you have some text or data in the database or hard coded the text, there is a text box called search box which search your text enter in the search box.

Code explanation: 2 files are included in the script, one of them have the search script, called jquery. Quick search is (and one is jquery, js the normal jquery file ). This file having the jquery search concept so this is better to include this file before using the jquery search script.

$(document).ready(function () {
$(‘table#searchoption tbody tr’).quicksearch({
stripeRowClass: [‘odd’, ‘even’],
position: ‘before’,
attached: ‘#searchoption’,
labelText: ‘Search ‘,
loaderImg: ‘images/loading.gif’
});
$(‘#checkAllAuto’).click( function(){ $(“INPUT[type=’checkbox’]”).
attr(‘checked’, $(‘#checkAllAuto’).is(‘:checked’)); } )
});

The above script uses in the search example, this is the script for the search option. If you can see the hml part, it have an option “id= search option” in the table. Which is for applying the serch script on the table data?/td>
