How to implement html input drop-down menu
This time I will show you how to implement html input drop-down menu, what are the precautions to implement html input drop-down menu, the following is a practical case, let’s take a look .
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> </head> <body> <?php echo ' <form name="DDForm" method="GET" action=""> <div style="position:relative;"> <span style="margin-left:100px;width:18px;overflow:hidden;"> <select style="width:180px;margin-left:-100px" onchange="this.parentNode.nextSibling.value=this.value" name="hh"> <option value="汽车">汽车 </option> <option value="火车"> 火车 </option> <option value="飞机"> 飞机 </option> </select> </span><input name="box" style="width:160px;position:absolute;left:0px;"> <input value="提交" name="submit" type="submit"/> </div> </form>'; $aa=$_GET['hh']."111"; // select 下拉菜单的值 $bb=$_GET['box']."222"; // 输入框的值 echo $aa; echo "</br>"; echo $bb; // 要获得可输入下拉菜单的值，只要获得输入框的值即可。 ?> </body> </html>
To get the value that can be entered into the drop-down menu, just get the value of the input box.
Note:
</span><input name="box" style="width:160px;position:absolute;left:0px;">
This line must be in one line and cannot be written as
</span> <input name="box" style="width:160px;position:absolute;left:0px;">
After the line break, the value of the drop-down menu cannot be displayed in the input box.
You can also automatically select matching menu values based on the input content.
