how can i change the inner html by getting element by index
i want to change the content of cells according to their index values
<table>
<tr><td></td><td></td></tr>
<tr><td></td><td></td></tr>
<tr><td></td><td></td></tr>
</table>
function LFLS() {
// LFLS => load from local Storage
for (i = 0; i < localStorage.length; i++) {
key = localStorage.key(i);//it return values like ("1,2","2,5", etc.)
console.log(key)
row = key.split(",")[0];
col = key.split(",")[1];
//how to get the cell by row and col
}
}
As Sakil said you can use eq(). Try this:
function LFLS() {
// load from local Storage
for (i = 0; i < localStorage.length; i++) {
key = localStorage.key(i);
row = key.split(",")[0];
col = key.split(",")[1];
// how to get the cell by row and col
$("table tr").eq(row).children().eq(col).html('NEW VALUE')
}
}
I believe you need the following snippets.
Before your for loop
const rows = $("table tr");
After you obtain row & col variables
const cellToUpdate = rows[row].children[col];
Alternatively, if you're looking to programatically loop through the table you could use the following snippet.
<script type="text/javascript">
const rows = $("table tr");
for( i = 0; i < rows.length; i++ ) {
const currRow = rows[i];
const rowChildren = currRow.children;
for( n = 0; n < rowChildren.length; n++ ) {
const cell = rowChildren[n];
cell.innerHTML = "My new data for row: " + i + " in cell " + n;
}
}
</script>
Is something on the lines of below not going to work for you for some reason?
$("table tr:nth-of-type([your-row])).eq([your-col]).html([your_content]);
