Sifa cells
Sifa cells inahifadhi ukusanyiko wa seli
td
na th
za mstari tr.
Inatumika tu kwa mstari wa jedwali.
Syntax
tr.cells;
Mfano
Wacha tuweke vitanzi mistari yote ya jedwali kwa kutumia
sifa rows,
na kwa kila mstari tuweke vitanzi seli zake kwa kutumia
sifa 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);
}
}
Mfano
Wacha tuweke vitanzi mistari yote ya jedwali kwa kutumia
sifa rows
na tujue idadi ya seli katika kila mstari:
<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);
}
Mfano
Wacha tuweke rangi ya msingi kwa seli ya kwanza:
<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';
:
Mfano
Wacha tuweke rangi ya msingi kwa seli za jedwali kwenye diagonal:
<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';
}
