Show tooltip on hover
提问by Andy Andy
Fiddle:http://jsfiddle.net/G38nx/
小提琴：http: //jsfiddle.net/G38nx/
So I have this table. I want to show a tooltip while rolling over certain td. For example pointing at cell with value 27 should show a tooltip "160cm:70kg".
所以我有这张桌子。我想在滚动某些 td 时显示工具提示。例如，指向值为 27 的单元格应显示工具提示“160cm:70kg”。
Any easy way to do it?
有什么简单的方法可以做到吗？
<table>
<tr>
<th></th><th>50kg</th><th>55kg</th><th>60kg</th><th>65kg</th><th>70kg</th>
</tr>
<tr>
<th>160cm</th><td>20</td><td>21</td><td>23</td><td>25</td><td>27</td>
</tr>
<tr>
<th>165cm</th><td>18</td><td>20</td><td>22</td><td>24</td><td>26</td>
</tr>
<tr>
<th>170cm</th><td>17</td><td>19</td><td>21</td><td>23</td><td>25</td>
</tr>
<tr>
<th>175cm</th><td>16</td><td>18</td><td>20</td><td>22</td><td>24</td>
</tr>
</table>

Here's how you might create the titles. It's fairly easy from that point to apply jQueryUI Tooltips, which allow custom styling.
以下是您创建标题的方法。从那时起，应用允许自定义样式的 jQueryUI 工具提示相当容易。

$(this).tooltip({
content: "<img src='http://placehold.it/50x50' />",
show: false,
hide: false
});
Update: Per your comment, here's an example with image content and instant (no transition) show and hide:
更新：根据您的评论，这是一个包含图像内容和即时（无过渡）显示和隐藏的示例：

http://jsfiddle.net/isherwood/G38nx/31
<th data-image-src="<img src='/images/myImage.jpg' />">...</th>
You'd have to use a data attribute to specify images for each cell, something like:
您必须使用数据属性为每个单元格指定图像，例如：
$(this).tooltip({
content: $(this).attr('data-img-src'),
show: false,
hide: false
});
... and then:
... 进而：
<div id="uguu"></div>
