for (var i = 1; i -Go服务器开发

您可以按以下方式修改代码，以使set_client_selfloop(1, ${i})中的i符合您的要求：

for (var i = 1; i <= 12; i++) {
    var start = (i - 1) * 4 + 1;
    var end = i * 4;

    title_val += `
    <tr>
        <td class="qdd_value">${client_selfloop(i, start, end)}</td>
    </tr>`;
}

function client_selfloop(i, start, end) {
    var optionsHTML = '';
    
    for (var j = start; j <= end; j++) {
        optionsHTML += `<option value=${j}>${j}</option>`;
    }

    return `
    LANE1: <select id='client_set_selfloop1${i}' style='width:115px'>${optionsHTML}</select> 
    <button onclick="set_client_selfloop(1, ${i})" style='margin-left:-3px;margin-top:3px;'>设置</button><br>
    
    LANE2: <select id='client_set_selfloop2${i}' style='width:115px'>${optionsHTML}</select> 
    <button onclick="set_client_selfloop(2, ${i})" style='margin-left:-3px;margin-top:3px;'>设置</button><br>
    
    LANE3: <select id='client_set_selfloop3${i}' style='width:115px'>${optionsHTML}</select> 
    <button onclick="set_client_selfloop(3, ${i})" style='margin-left:-3px;margin-top:3px;'>设置</button><br>
    
    LANE4: <select id='client_set_selfloop4${i}' style='width:115px'>${optionsHTML}</select> 
    <button onclick="set_client_selfloop(4, ${i})" style='margin-left:-3px;margin-top:3px;'>设置</button><br>
    `;
}

这样修改后，当i为1时，LANE1-LANE4中的client_set_selfloop1${i}值将为1-4；当i为2时，值为5-8；当i为3时，值为9-12。以此类推。
