Salve, sono nuovo nel mondo della programmazione.
Ho un po di esperienza in php, ma in javascript ......
ho un problema con un codice:
ho 2 boxarea, nella prima ho un elenco di 5000 record e selezionandone alcune, vengono riportate nella seconda boxarea
il mio problema e nel filtraggio.
dovendo filtrare 5000 righe, il programma risulta troppo lento!!
mi occorre che il filtraggio lo facesse solo sulle iniziali delle stringhe e non all'interno:
esempio:
record 1 > casa bella milano marittima
record 2 > appartamento milano
record 3 > milano settembre bicicletta
record 4 > casa bici carte sapone
se nel campo filtro inserisco milano, nel boxarea mi filtra i record 1-2-3 perche contenuto nella stringa, io voglio che mi faccia vedere solo il record 4
come posso modificara il seguente script?
