Hur jag skulle försöka lösa det. Observera att detta inte täcker alla (några?) eventualiteter eller mycket felhantering. Du får utveckla det lite själv. t.ex. använde jag ingång för en väljare, du behöver "välj". Arrayerna kanske inte matchar. Du kan behöva en helt annan väljare som till exempel av td[headers]. Kanske kommer ditt returobjekt behöva innehålla andra eller fler värden. Dina js kan behöva utökas mer.
Ändå bör det ge dig en bra bas att utgå ifrån!
Javascript:
function validaterows(){
var arrf01 = [], arrf02 = [];
//fetch all the values from the source columns and put them in
//a javascript array.
$("input[name=f03]").each(function(){
arrf01.push($v(this));
});
$("input[name=f04]").each(function(){
arrf02.push($v(this));
});
//provide the constructed arrays to the on-demand process by using
//the global f## arrays
apex.server.process ( "MY_PROCESS", {
f01: arrf01
, f02: arrf02
}, {
, success: function( pData ) {
//pData should be an object, because jquery will have parsed the returned json-string
apex.debug(pData);
$.each(pData.validationArray, function(index, value){
if ( value === 'INVALID' ) {
// do something here when the result is invalid
// maybe you want to color something red for example
alert('The data at row '+index+' is not valid!');
};
});
}
} );
}
Plsql-process på begäran:
DECLARE
l_return VARCHAR2(4000);
BEGIN
FOR i IN apex_application.g_f01.count
LOOP
-- remember: the f## arrays are varchar arrays. Important for comparisons.
-- Also take into account that the values could NOT be numeric at all.
-- you'll probably want to run each value through an is-number check or else
-- you'll run into ORA errors
IF to_number(apex_application.g_f01(i)) > to_number(apex_application.g_f02(i))
THEN
l_return := l_return || ',"INVALID"';
ELSE
l_return := l_return || ',"VALID"';

END LOOP;
IF l_return IS NOT NULL
THEN
-- create a json string
