使用jQuery“突出显示"光标下的内容 [英] Using jQuery to "highlight" content under cursor
问题描述
我正在尝试编写一些jQuery代码，通过在其周围添加边框来突出显示光标当前悬停的元素.这是我到目前为止的代码:
I'm trying to write some jQuery code that will highlight the element the cursor is currently hovering over by adding a border around it. Here is the code I have so far:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Hover Test</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script>
$(function() {
$("*:not(html, head, body)").hover( function () {
$(this).css("border", "2px solid purple");
},
function () {
$(this).css("border", "none");
}).click( function () {
alert($(this).html());
});
});
</script>
</head>
<body>
<div>
<p>This is paragraph one</p>
<p>This is paragraph two</p>
</div>
<span id="curtag"></span>
</body>
</html>
问题是，当我将鼠标悬停在下面示例中的某个段落上时，它还会突出显示父标记(在这种情况下为div).另外，当我单击该段落时，它给了我p的html，然后给了div的html，但是，我只希望p标记中的html.有关如何解决此问题的任何建议?
The problem is when I hover over something like a paragraph in the example below it also highlights the parent tag in this case the div. Additionally, when I click on the paragraph it gives me the html of the p and then the html of the div, however, I only want the html in the p tag. Any suggestions on how to fix this?
推荐答案
添加
return false;
像这样
$(function() {
$("*:not(html, head, body)").hover( function () {
$(this).css("border", "2px solid purple");
return false;
},
function () {
$(this).css("border", "none");
}).click( function () {
alert($(this).html());
return false;
});
});
停止mouseover事件从起泡到父级.
to stop the mouseOver event from bubbeling to the parent.
