如何使第一列的每一行都可以单击以从整行中获取数据？ JavaScript

Question

I'm trying to make a table's first column's each row (in this case order IDs) clickable so that I can display more info from this specific order ID in another container on my website. I looped through some JSON data to create the table like this:

function printData(jsonData) {
    let myTable = document.getElementById("jsonTable")
    for(let i=0; i < jsonData.length; i++) {
        let row = `<tr>
                        <td>${jsonData[i].orderid}</td>
                        <td>${jsonData[i].customerid}</td>
                        <td>${jsonData[i].customer}</td>
                        <td>${jsonData[i].invaddr}</td>
                        <td>${jsonData[i].delivaddr}</td>
                        <td>${jsonData[i].deliverydate}</td>
                        <td>${jsonData[i].respsalesperson}</td></tr>`


            jsonTable.innerHTML += row
    }
}

And this is how my HTML file looks like:

        <div class="datatable">

            <div class="datatablecontent">
                <table class="jsontable">
                    <tr id="jsontr">
                        <th>Order ID</th>
                        <th>Customer ID</th>
                        <th>Customer</th>
                        <th>InvAddr</th>
                        <th>Delivery Address</th>
                        <th>Delivery Date</th>
                        <th>Resp. For Sale </th>
    
                        <tbody id="jsonTable">
    
                        </tbody>
                    </tr>
    
                </table>
            </div>
        </div>

While iterating over jsonData , you can declare a callback in an event listener.

Because you're using template literals, I'm keeping it concise and passing the row index. You can also pass the data itself by adding an event listener in JS, to do that you'll need to access the element.

 function logRowData(index) { console.log(jsonData[index]) } let jsonData = [ {orderid: 0, customerid:14, customer: 'abc'}, {orderid: 1, customerid:25, customer: 'xyz'} ] printData(jsonData) function printData(jsonData) { let myTable = document.getElementById("jsonTable") for(let i=0; i < jsonData.length; i++) { let row = `<tr> <td onclick={logRowData(${i})}>${jsonData[i].orderid}</td> <td>${jsonData[i].customerid}</td> <td>${jsonData[i].customer}</td></tr>` jsonTable.innerHTML += row } }

 <div class="datatable"> <div class="datatablecontent"> <table class="jsontable"> <tr id="jsontr"> <th>Order ID</th> <th>Customer ID</th> <th>Customer</th> <tbody id="jsonTable"> </tbody> </tr> </table> </div> </div>
