过滤/搜索表HTML

Question

我的搜索表有问题。 我使用W3中的代码，此代码用于过滤一列。 有人会这样做，以便一次过滤两列吗？例如，名称和姓氏

代码：

func setUpLocalNotification(){
    let calendar = NSCalendar(identifier: .gregorian)!
    var dateFire = Date()

    var fireComponents = calendar.components([NSCalendar.Unit.day,NSCalendar.Unit.month,NSCalendar.Unit.year,NSCalendar.Unit.hour,NSCalendar.Unit.minute], from: dateFire)

    fireComponents.year = addAlarm.year
    fireComponents.month = addAlarm.month
    fireComponents.day = addAlarm.day
    fireComponents.hour = addAlarm.hour
    fireComponents.minute = addAlarm.minute

    dateFire = calendar.date(from: fireComponents)!

    let localNotification = UILocalNotification()
    localNotification.fireDate = dateFire
    localNotification.alertBody = addAlarm.msg
    localNotification.soundName = UILocalNotificationDefaultSoundName
    localNotification.userInfo = ["Uid" : addAlarm.id]
    UIApplication.shared.scheduleLocalNotification(localNotification)

}

Answer 1

您还应该搜索第二个td。

function myFunction() {    
    table, tr, td, i; input = document.getElementById("myInput"); 
    filter = input.value.toUpperCase(); 
    table =document.getElementById("myTable"); 
    tr = table.getElementsByTagName("tr");
    for (i = 0; i < tr.length; i++) { 
        td = tr[i].getElementsByTagName("td")[0]; 
        td2 = tr[i].getElementsByTagName("td")[1];
        if (td && td2) { 
           if (td.innerHTML.toUpperCase().indexOf(filter) > -1 || td2.innerHTML.toUpperCase().indexOf(filter) > -1) { 
             tr[i].style.display = ""; 
           } 
           else { tr[i].style.display = "none"; } 
        }
    }
}
