The Apex JavaScript API <\/a>has some very convenient functions to access the values of page items.<\/p><\/blockquote>\n

For example, if you wante to access the contents of a text field with JavaScript, would would need to reference it something like this:<\/p>\n

$x(\"P2_TEXT_FIELD\").value;<\/pre>\n
If the item you want to reference is a display only item, then the syntax changes:<\/p>\n
x = $(\"#P2_DISPLAY_ONLY\").text();<\/pre>\n
If you need to set the values of these items, the you need to use the varying syntax as well:<\/p>\n
$x(\"P2_TEXT_FIELD\").value = \"Hello World!\";<\/pre>\n
or<\/p>\n
$(\"#P2_DISPLAY_ONLY\").text(\"Hello World!\");<\/pre>\n
Dealing with these various syntax constructs can be confusing. Fortunately the Apex JavaScript API makes this process much easier. To get page item values simply use $v(\u201c<item_name>\u201d):<\/p>\n
x = $v(\"P2_TEXT_FIELD\");\r\ny = $v(\"P2_DISPLAY_ONLY\");<\/pre>\n
To set the item values use:<\/p>\n
$s(\"P2_TEXT_FIELD\",\"Hello World!\");\r\n$s(\"P2_DISPLAY_ONLY\",\"Hello World!\");<\/pre>\n
See an example on my demo page<\/a>.<\/p>\n

The $v2() is handy if you need to access multiple items in an array. For example multiple selections from check boxes or from a shuttle control can be fetched as an array and handled that way in JavaScript:<\/p>\n
myArr = $v2(\"P2_SHUTTLE_CONTROL\");\r\nfor (idx=0; idx<myArr.length; idx++) {\r\n\u00a0 \/\/do something with myArr[idx];\r\n}<\/pre>\n
An example of this functionality can be seen on my demo page<\/a>, where I also compare $v() and $v2() when used in an array.<\/p>\n
