jQuery mouseover显示隐藏的div并显示div,如果只有鼠标仍然在div上

我的鼠标悬停和鼠标输出功能有问题。当我鼠标悬停一个链接时,它显示一个隐藏的<div>,当我鼠标输出div时,它隐藏了div。问题是,如果我将鼠标悬停在链接上,那么我将鼠标移动到不在div上方的其他地方,div将不会消失。

如果我使用链接的mouseout事件来设置div的可见性,那么我将无法将鼠标悬停在div上。

这是我的HTML:

我使用setTimeout函数来更改css属性。将setTimeout的时间间隔设置为~333-500毫秒,并将Div的鼠标悬停设置为清除超时。然后,在div本身的mouseout上,再次设置计时器:)

实施例/答案:

// timer for hiding the div
var hideTimer;

// show the DIV on mouse over
$("#show_div").mouseover(function() {
    // forget any hiding events in timer
    clearTimeout( hideTimer );
    $("#hello").css('visibility', 'visible');
});

$("#hello").mouseover(function() {
    clearTimeout( hideTimer );
    $("#hello").css('visibility', 'visible');
});

// set a timer to hide the DIV
$("#show_div").mouseout(function() {
    hideTimer = setTimeout( hideHello, 333 );
});

$("#hello").mouseout(function() {
    hideTimer = setTimeout( hideHello, 333 );
});

// hides the DIV
function hideHello() {
    $("#hello").css('visibility', 'hidden');
}

将整个东西放在一个容器中,并将鼠标事件放在:

试一试: http://jsfiddle.net/hGTPp/

HTML

<div id='container'>
    <a id="show_div" href="#">Link text</a>
    <div id="hello" style="visibility:hidden;">
        <ul>
            <li>
                Coffee
            </li>
            <li>
                Tea
            </li>
            <li>
                Milk
            </li>
        </ul>
    </div>
</div>

的jQuery

$("#container").mouseover(function() {
    $("#hello").css('visibility', 'visible');
});
$("#container").mouseout(function() {
    $("#hello").css('visibility', 'hidden');
});​

请改用.hover()。它允许您指定handlerInhandlerOut个事件。 E.g。

<强>的jQuery

<script type="text/javascript">
  $(document).ready(function() {
    $("#linkdiv").hover(function() {
      $("#hello").show();
    }, function() {
      $("#hello").hide();
    });
  });
</script>

HTML

<div id="linkdiv">
  <a id="show_div" href="#">Link text</a>

  <div id="hello" style="display: none;">
    <ul>
      <li>Coffee</li>
      <li>Tea</li>
      <li>Milk</li>
    </ul>
  </div>
</div>

修改:在Nick发表评论后稍稍更改了代码。谢谢尼克。
