I created a code to convert json data to html table using javascript and ajax: (column 1 is text, column 2 is link, column 4 is image link) Data: This is the code, it work well, but on the table result, I want to hide column 2 and put the link in column 2 in an anchor in column 1

work on each td each one apart inside tr loop when loading data from json file

I created a code to convert json data to html table using javascript and ajax: (column 1 is text, column 2 is link, column 4 is image link)

Data:

[
["Product_1_Title", "www.website1.com", 20, "https://images-na.ssl-images-amazon.com/images/I/81b1roZwACL._AC_SL1500_.jpg"],
["Product_2_Title", "www.website2.com", 50, "https://images-na.ssl-images-amazon.com/images/I/71W1KvLH3sL._AC_SL1500_.jpg"],
...
]

This is the code, it work well, but on the table result, I want to hide column 2 and put the link in column 2 in an anchor in column 1 so the Title become clickable link, and put the image link on column 4 into src so the picture shown on the cell.

Answer

Instead of iterating through the cells, if you know the position of the columns in the array you can hard code the row.

function populateTable(json){
    while(TabBody.firstChild){TabBody.removeChild(TabBody.firstChild);}
    json.forEach((row) => { 
        const tr = document.createElement("tr");
        let td = document.createElement("td");
        td.innerHTML = `<a href='${row[1]}'>${row[0]}</a>`
        tr.appendChild(td);  
        td = document.createElement("td");              
        td.innerHTML = row[2];
        tr.appendChild(td);   
        td = document.createElement("td");
        td.innerHTML = `<img src="https://${row[3]}" class="img-fluid"/>`;
        tr.appendChild(td);   
        TabBody.appendChild(tr);
    })
}

And take out the second column in the table instead of hiding it

<thead>
    <tr>
        <th>column_1</th>
        <th>column_2</th>
        <th>column_3_link</th>
    </tr>
</thead>
