Īpašība cells
Īpašība cells glabā šūnu kolekciju
td
un th
rindai tr.
Attiecas tikai uz tabulas rindu.
Sintakse
tr.cells;
Piemērs
Izejam cauri visām tabulas rindām, izmantojot
īpašību rows,
un katrā rindā izejam cauri tās šūnām, izmantojot
īpašību cells:
<table id="table">
<tr>
<td>1</td><td>2</td><td>3</td>
</tr>
<tr>
<td>4</td><td>5</td><td>6</td>
</tr>
<tr>
<td>7</td><td>8</td><td>9</td>
</tr>
</table>
let table = document.querySelector('#table');
for (let row of table.rows) {
for (let cell of row.cells) {
console.log(cell);
}
}
Piemērs
Izejam cauri visām tabulas rindām, izmantojot
īpašību rows
un uzzinām šūnu skaitu katrā rindā:
<table id="table">
<tr>
<td>1</td><td>2</td><td>3</td><td>4</td>
</tr>
<tr>
<td>1</td><td>2</td><td>3</td>
</tr>
<tr>
<td>1</td><td>2</td>
</tr>
</table>
let table = document.querySelector('#table');
for (let row of table.rows) {
console.log(row.cells.length);
}
Piemērs
Iestatīsim fonu pirmajai šūnai:
<table id="table">
<tr>
<td>1</td><td>2</td><td>3</td>
</tr>
<tr>
<td>4</td><td>5</td><td>6</td>
</tr>
<tr>
<td>7</td><td>8</td><td>9</td>
</tr>
</table>
table, td {
border: 1px solid black;
}
let table = document.querySelector('#table');
table.rows[0].cells[0].style.background = 'red';
:
Piemērs
Iestatīsim fonu tabulas šūnām pa diagonāli:
<table id="table">
<tr>
<td>1</td><td>2</td><td>3</td>
</tr>
<tr>
<td>4</td><td>5</td><td>6</td>
</tr>
<tr>
<td>7</td><td>8</td><td>9</td>
</tr>
</table>
table, td {
border: 1px solid black;
}
let table = document.querySelector('#table');
let rows = table.rows;
for (let i = 0; i < rows.length; i++) {
rows[i].cells[i].style.background = 'red';
