Hi I´m trying to make this JS work in 19.11.06, even though it is noted to work on 16.05. The JS was supposed to be enabled only on cataloging form, however, it locks/disables the save button in patron creations form. Any idea what's wrong with it? / https://wiki.koha-community.org/wiki/JQuery_Library#Check_validity_of_ISBN.2... This is the part of the JS that locks me down: if ( $("#cat_addbiblio") ) // only do this in the addbiblio form { // add an additional event handler to the save buttons ( one already exists: .onOption() ) $("#saverecord, #saveandview, #saveanditems, #saveandcontinue").click( function( event ) { var mes = ""; // run all tests as functions which might add a new error message to the existing ones mes = test020a( mes ); mes = test022a( mes ); mes = test024a( mes ); mes = test856a( mes ); if (mes != "") { alert(mes); event.stopImmediatePropagation(); // block the other event handlers which trigger submission of the form return false; } else { return true; } }); }; // end if in addbiblio form Regards Alvaro |----------------------------------------------------------------------------------------| Stay safe / Cuídate/ Reste sécurisé *7* Switch off as you go / Apaga lo que no usas / Débranchez au fur et à mesure. *q *Recycle always / Recicla siempre / Recyclez toujours P Print only if absolutely necessary / Imprime solo si es necesario / Imprimez seulement si nécessaire
