我的选择包含两个字段,文本字段仅选取其中一个字段。这是我的代码:
<script>
function ProdValue(data) {
document.getElementById("ProdName").value = data.value;
}
</script>
<select name="ProdName" id="ProdName" onchange ="ProdValue(this)">
<?php
$sql = "Select * from tblProduct";
if ($result = mysqli_query($conn, $sql));
while ($row = mysqli_fetch_assoc($result))
{
echo "<option value='". $row['Brand']."', '".$row['ProductName']."'>".$row['Brand']." ".$row['ProductName']. '</option>';
}
?>
</select>
我如何获得ProductName?

由于您的选项value
包含以逗号分隔的品牌和产品名称,因此您可以执行以下操作:
function ProdValue(data) {
var optval = data,
prod_name = optval.split(",")[1];
console.log( prod_name ); //here is your product name
document.getElementById("ProdName").value = optval;
}

请改用它。如果两列实际上都定义为NOT NULL,那么CONCAT()就足够了:
<?php
$sql = "Select CONCAT(Brand, ProductName) as CombineColumn from tblProduct";
if ($result = mysqli_query($conn, $sql))
{
while ($row = mysqli_fetch_assoc($result))
{
echo "<option value='". $row['CombineColumn']."'>".$row['CombineColumn']."</option>";
}
}
?>
