HomeBackend DevelopmentPHP Tutorialhtml标签select的问题 数据查询结果显示在下拉菜单中

html select下拉菜单中有自己手动添加进来的菜单,比如


现在我从数据库中查询的结果是2,如何让页面显示的时候,下拉菜单自动锁定在“价值2”呢?


回复讨论(解决方案)


$value = 2;
echo "<script>document.getElementById('name').value = $value</script>";


$value = 2;
echo "<script>docu…… <br /> 太好了,问题解决 </script>

<select name="sex" id="sex"/><option value=""></option><option value="男">男</option><option value="女">女</option></select>        <php>        	$value=$list['sex'];            echo "<script>document.getElementById('sex').value =$value</script>";        </php>


这个地方有什么错误吗?老是不行

<select name="sex" id="sex"><option value=""></option><option value="男">男</option><option value="女">女</option></select><?php$value=$list['sex'];echo "<script>document.getElementById('sex').value ='$value'</script>";?>
