error_reporting(0);

// Report simple running errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);

jQuery – get element by id, class, name

admin programming Add you comment

In jQuery, you can get elements with CSS class name and id easily.

For example,

1. ID: #id

  • $(‘#idA’) – selects all elements that have an id of ‘idA’, regardless of its tag name.
  • $(‘div#idA’) – selects all div elements that has an id of ‘idA’.

2. Class: .classname

  • $(‘.classA’) – selects all elements that have an class name of ‘classA’, regardless of its tag name.
  • $(‘div.classA’) – selects all div elements that has an class name of ‘classA’.

3. Class: [name="value"]

  • $(‘div[name^="nameA"]’) – selects all elements that have an name of ‘nameA’, regardless of its tag name.
  • e.g. [name*="value"], [name~="value"], [name$="value"]

3. Change attr: $(‘#idA’).attr()

  • $(‘#idA’).attr(‘src’, ‘value) – change value of attribute that have an idof ‘idA’, regardless of its tag name.

Full Example

<html>
<head>
<title>jQuery Get element with class name and id</title>

<script type="text/javascript" src="jquery-1.3.2.min.js"></script>

</head>

<script type="text/javascript">

$(document).ready(function(){

    var $element = $('.classABC').html();
    alert($element);

    var $element = $('#idABC').html();
    alert($element);

});

</script>
<body>

<h1>jQuery Get element with class name and id</h1>

	<div class="classABC">
		This is belong to 'div'
	</div>

	<div id="idABC">
		This is belong to 'div id="idABC"'
	</div>

</body>

MYSQL enum and set

admin programming Add you comment

The ENUM Type

An ENUM is a string object with a value chosen from a list of permitted values that are enumerated explicitly in the column specification at table creation time.

An enumeration value must be a quoted string literal; it may not be an expression, even one that evaluates to a string value. For example, you can create a table with an ENUM column like this:

CREATE TABLE sizes (
    name ENUM('small', 'medium', 'large')
);






The SET Type








A SET is a string object that can have zero or more values, each of which must be chosen from a list of permitted values specified when the table is created. SET column values that consist of multiple set members are specified with members separated by commas (“,”). A consequence of this is that SET member values should not themselves contain commas.


For example, a column specified as SET('one', 'two') NOT NULL can have any of these values:


''
'one'
'two'
'one,two'


A SET can have a maximum of 64 different members.


 


ENUM and SET Constraints






ENUM and SET columns provide an efficient way to define columns that can contain only a given set of values. SeeSection 10.4.4, “The ENUM Type”, and Section 10.4.5, “The SET Type”. However, in MySQL 4.1 and earlier, ENUMand SET columns do not provide true constraints on entry of invalid data:




    

  • ENUM columns always have a default value. If you specify no default value, then it is NULL for columns that can have NULL, otherwise it is the first enumeration value in the column definition.
    • 

  • If you insert an incorrect value into an ENUM column or if you force a value into an ENUM column with IGNORE, it is set to the reserved enumeration value of 0, which is displayed as an empty string in string context.
    • 

  • If you insert an incorrect value into a SET column, the incorrect value is ignored. For example, if the column can contain the values 'a', 'b', and 'c', an attempt to assign 'a,x,b,y' results in a value of 'a,b'.
