The Apex JavaScript API has some very convenient functions to access the values of page items.
For example, if you wante to access the contents of a text field with JavaScript, would need to reference it something like this:
$x("P7_TEXT_FIELD").value;
or
$("#P7_TEXT_FIELD").val();
If the item you want to reference is a display only item, then the syntax changes:
x = $("#P7_DISPLAY_ONLY").text();
If you need to set the values of these items, the you need to use the varying syntax as well:
$x("P7_TEXT_FIELD").value = "Hello World!";
or
$('#P7_TEXT_FIELD').val("Hello World!");
or
$("#P7_DISPLAY_ONLY").text("Hello World!");
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(“<item_name>”):
x = $v("P7_TEXT_FIELD");
y = $v("P7_DISPLAY_ONLY");
To set the item values use:
$s("P7_TEXT_FIELD","Hello World!");
$s("P7_DISPLAY_ONLY","Hello World!");
See an example on my demo page.
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:
myArr = $v2("P7_SHUTTLE_CONTROL");
for (idx=0; idx<myArr.length; idx++) {
//do something with myArr[idx];
}

Hi,
ReplyDeletei have this javascript funcion called on KeyUp:
function verifyIBAN(pThis){
var iban = pThis.value;
var ajaxCall = new htmldb_Get('P3_VERIFYIBAN',&APP_ID.,'APPLICATION_PROCESS=VERIFY_IBAN',&APP_PAGE_ID.);
// Images with cancel and confirm image
document.getElementById("P3_IBAN_NOTOK").style.visibility = "hidden";
document.getElementById("P3_IBAN_OK").style.visibility = "hidden";
// call pl/sql function that returns OK / NOT OK
ajaxCall.addParam('x01',iban);
var gReturn = ajaxCall.get(); // esegue la chiamata a Verify Iban
// This if goes always in else
if ($v("P3_VERIFYIBAN") == "OK"){
document.getElementById("P3_IBAN_OK").style.visibility = "visible";
} else {
document.getElementById("P3_IBAN_NOTOK").style.visibility = "visible";
}
}
It seems that the javascript is unable to get P3_VERIFYIBAN value (it's a display only field)
Please help.
Thanks in advance.
