Question

我有一个div，其中包含菜单，另一个包含搜索框。每当我在搜索框中输入时，结果都在菜单div下面

error

顺便说一下。我使用Sergey Pimenov的Metro UI

这是我在主页上的代码：

这是来自livesearch.php的代码

<?php
$xmlDoc=new DOMDocument();
$xmlDoc->load("links.xml");

$x=$xmlDoc->getElementsByTagName('link');

//get the q parameter from URL
$q=$_GET["q"];

//lookup all links from the xml file if length of q>0
if (strlen($q)>0)
{
$hint="";
for($i=0; $i<($x->length); $i++)
  {
  $y=$x->item($i)->getElementsByTagName('title');
  $z=$x->item($i)->getElementsByTagName('url');
  if ($y->item(0)->nodeType==1)
    {
    //find a link matching the search text
    if (stristr($y->item(0)->childNodes->item(0)->nodeValue,$q))
      {
      if ($hint=="")
        {
        $hint="<a href='" .
        $z->item(0)->childNodes->item(0)->nodeValue . 
        "' target='_blank'>" . 
        $y->item(0)->childNodes->item(0)->nodeValue . "</a>";
        }
      else
        {
        $hint=$hint . "<br /><a href='" .
        $z->item(0)->childNodes->item(0)->nodeValue . 
        "' target='_blank'>" . 
        $y->item(0)->childNodes->item(0)->nodeValue . "</a>";
        }
      }
    }
  }
}

// Set output to "no suggestion" if no hint were found
// or to the correct values
if ($hint=="")
  {
  $response="no suggestion";
  }
else
  {
  $response=$hint;
  }

//output the response
echo $response;
?>

Answer 1

您可以尝试添加

document.getElementById("livesearch").style.zIndex="1000";

注意： z-index仅适用于定位元素（位置：绝对，位置：相对或位置：固定）。

将其设置为1000，因此它有望成为最顶层的元素

Answer 2

您可能会发现此页面很有用

http://www.w3schools.com/cssref/pr_pos_z-index.asp

z-index是一个CSS属性，它允许HTML元素从查看器“更近”或“更远”地移动。你应该能够给搜索框及其结果一个z-index为1，将其置于所有其他div的前面

将div定位在另一个div下面
