我试图在jquery和css中点击id作为设备的跨度时在光标附近显示div
答案 0 :(得分:12)
我建议添加一个隐藏的div:
<div id="message">
This is a message
</div>
使用CSS:
#message { position: absolute; display: none; }
然后显示:
$("#equipment").click(function(evt) {
$("#message").css({
top: evt.pageY,
left: evt.pageX
}).toggle();
});
这是一个完整的例子:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
$("#equipment").click(function(evt) {
$("#message").css({
top: evt.pageY + 5,
left: evt.pageX + 5
}).show();
});
});
</script>
<style type="text/css">
html, body, div { margin: 0; padding: 0; border: 0 none; }
#wrapper { margin: 0 auto; width: 600px; }
#equipment { color: green; }
#message { display: none; position: absolute; text-align: center; padding: 10px; width: 120px; background: red; color: white; font-weight: bold; }
</style>
</head>
<body>
<div id="wrapper">
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor <span id="equipment">incididunt ut labore et dolore</span> magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

<div id="message">This is a message</div>
</div>
</body>
</html>

在您向我们提供更具体的信息之前,这是您的解决方案:
$("span#equipment").click(function(){
$(".invisiDiv").show(); // .toggle() if you need it to close with next click
});
-
<p><span id="equipment">Equipment</span></p>
<div class="invisiDiv" style="display:none;">
<p>This div will be shown once you click on the span element above</p>
</div>
如果您需要此.invisiDiv
始终在鼠标附近说,您可以根据the current x/y position of the mouse动态重新定位它:
$("span#equipment").click(function(e){
$(".invisiDiv")
.css({top:e.pageX,left:e.pageY})
.show(); // .toggle() if you need it to close with next click
});
并向其添加以下CSS规则:
.invisiDiv { position:absolute; width:100px; height:15px; }

另一种方式可能是这样的
HTML:
<span>click!</span>
Jquery的:
$('span').click(function()
{
$(this).showDiv('<div>I AM DIV</div>');
});
//plugin
jQuery.fn.showDiv = function (html)
{
var pos = $(this).position();
$(html).insertAfter('span').css({
position: "absolute",
top: (pos.top + 20) + "px",//customize top position
left: (pos.left) + "px"//customize left position
}).fadeIn();
return this;
}
一些CSS:
div{
background:red;
display:none;height:50px;width:50px
}
span{
position:absolute;
top:20px;
left:50px;
background:green;
}
