Dodaj wiersz na górze tabeli wygenerowany przez Javascript

Question

Zrobiłem błędne obliczenia w strukturze tabeli. Poniższy kod dotyczy gry lotto (znanego kawałka kodu myślę;))

Czy istnieje sposób na dodanie wiersza do tabeli wypełnionej liczbami? Naprawdę nie wiem, jak to zrobić.

Answer 1

Można również zrobić używając insertBefore:

$('<tr><td>Stuff</td></tr>').insertBefore('table > tbody > tr:first'); 

lub before:

$('table > tbody > tr:first').before('<tr><td>Stuff</td></tr>'); 

lub prependTo:

$("<tr><td>prependTo</td></tr>").prependTo("table > tbody"); 

Answer 2

Zastosowanie metody insertRow() na <tbody>

var myTable = document.getElementById('myTable'), 
    tbody = myTable.tbodies[0], 
    tr = tbody.insertRow(-1) // puts it at the start 
; 

var td = document.createElement('td'); 
    td.innerHTML = "Something"; 
tr.appendChild(td); 

Answer 3

JQuery:

$("#myTable tbody").prepend("<tr><td>...contents...</td></tr>"); 

Answer 4

dodawanie wiersza na szczycie stołu zaniku tle:

$('button').click(function() { 
    $('<tr class="anim highlight"><td>new text</td></tr>') 
    .hide() 
    .prependTo('table tbody') 
    .fadeIn("slow") 
    .addClass('normal'); 
}); 

dodać animację przejścia tła :

.anim { 
    transition: background 5s linear; 
} 
.highlight{ 
    background: #FF3333; 
} 
.normal { 
    background: transparent; 
}

Answer 5

inny sposób: [! LINK]

var newHtml = '<div/>'; 

$('#tBody').html(newHtml + $('#tBody').html());
