google搜索页面具有以下代码,为什么下面的分配不起作用?我通过firefox扩展程序对其进行了测试。
$(".gLFyf.gsfi").val("12345");
input class =“ gLFyf gsfi” maxlength =“ 2048” name =“ q” type =“ text” jsaction =“ paste:puy29d” aria-autocomplete =“ both” aria-haspopup =“ false” autocapitalize =“ off “ autocomplete =” off“ autocorrect =” off“ role =” combobox“ spellcheck =” false“ title =”搜索“ value =”香蕉“ aria-label =”搜索“
