Olá galera, eu tenho um javascript aqui que faz uma busca na propria página, alguém consegue modificar esse código para que ele busque as informações em um banco de dados em JS? pois eu tenho umas 3500 linhas "the_entries" , dai fica muito pesado. Quando faço uma busca apareçe a menssagem "Um scrpt da página esta provocando a execução lenta do internet explorer". Se poderem me explicar com uma linguagem de leigo eu agradeço, pois não entendo quase nada de Javascript. Agradeço.....

Olá galera, eu tenho um javascript aqui que faz uma busca na propria página, alguém consegue modificar esse código para que ele busque as informações em um banco de dados em JS? pois eu tenho umas 3500 linhas "the_entries" , dai fica muito pesado. Quando faço uma busca apareçe a menssagem "Um scrpt da página esta provocando a execução lenta do internet explorer". Se poderem me explicar com uma linguagem de leigo eu agradeço, pois não entendo quase nada de Javascript. Agradeço.....
