我通过选择框动态添加一行。我面临以下代码的三个问题
function addrow(x){
alert(x);
for (var l=1; l <= x-1; l++){
$(function() {
var k=4;
// var addDiv1 = $('#table_row');
// var k = $('#table_row p').size() + 1;
var index = 4;
newRow = "<tr>" +
"<td><label>Select Pagelayout"+l+": </label></td><td><?php $dbLink = new mysqli('localhost', 'root', 'root', 'display');
// Check connection
if(mysqli_connect_errno()) {
die("MySQL connection failed: ". mysqli_connect_error());
}
else{
$sql = "SELECT name FROM layout";
$result = mysqli_query($dbLink, $sql) or die (mysqli_error($dbLink));
$select4 .= "<option value='select'>". select ."</option>";
while($row = $result->fetch_assoc()) {
$select4 .= "<option>".$row['name']."</option>";
}
echo "<select name='layout.'l'.' id='layout.'l'.'>".$select4."</select>";
mysqli_close($dbLink);
