我有MySQL表"名称":
id | name | country | age
1 | Mark | Germany | 20
2 | Jack | UK | 23
3 | Mary | US | 32
4 | Suzan | Italy | 15
我需要的是:
<html>
<body>
<select id="name" name="name" required >
<option></option>
<option value="<?php echo $row['id'];?>" >
<?php echo $row['name']; ?> - <? echo $row['country']; ?> - <? echo $row['age']; ?>
</option>
</select>
<input type="number" id="age" name="age" value=" " placeholder=" age" required>
</body>
</html>

你需要做两件事:
首先,将要用作值的值放在选项的值中。
为了简化示例,请参阅HTML,该选项的值是您需要的值!所以没有理由设置一个ID并获得年龄..即使有可能,也没有理由这样做..
var mySelect = document.getElementById("name");
mySelect.addEventListener("change", myFunction);
function myFunction() {
document.getElementById("age").value = mySelect.options[mySelect.selectedIndex].value;
};
&#13;
<select id="name" name="name" required >
<option value="1" >
name1 - country1 - age 1
</option>
<option value="2" >
name2 - country2 - age 2
</option>
<option value="3" >
name3 - country3 - age 3
</option>
<option value="4" >
name4 - country4 - age 4
</option>
</select>
<input type="number" id="age" name="age" value="" placeholder=" age" required>
&#13;
然后,第二:要获得上面的HTML,你可能需要在PHP中编写类似的东西
<select id="name" name="name" required >
<?php
// assuming you get your MySQL results in a array called $rows
foreach($rows as $row) {
echo '<option value="'.$row['age'].'">'.
$row['name'] . ' - ' . $row['country'] . ' - ' . $row['age']
.'</option>';
}
?>
</select>
<input type="number" id="age" name="age" value="" placeholder=" age" required>
