在.hta中切换隐藏/显示表td [英] Toggle hide/show table td in .hta
本文介绍了在.hta中切换隐藏/显示表td的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我已经看过几个关于这个主题的帖子，但是尽管尝试了不同的方法，我还是没有设法解决我自己的问题。
I've seen several of posts regarding this subject, but I have not managed to solve my own problem despite of having tried different methods.
我正在编程一个.hta文件，其中我的所有笔记标题都列在彼此之上。每当您单击一个音符标题时，该标题下的描述应该出现（切换/展开）。所有笔记都应该隐藏起来。
I am programming in a .hta file, where I have all my notes titles listed above each other. Whenever you click a note title the description should appear (toggle/expand) under the title. All the notes should start hidden.
sub searchdata
SQL_query = "SELECT * FROM dvd WHERE Title LIKE '%"& txtsrch.value &"%' OR Notes LIKE '%"& txtsrch.value &"%' ORDER BY Title"
Set rsData = conn.Execute(SQL_query)
strHTML2 = strHTML2 & ""
Do Until rsData.EOF = True
strHTML2 = strHTML2 & "<table width='97%' border='0' id='bodytext' style='border-bottom: solid #000000 1px;'><tr><span class'togglelink'><td width='70%' style='cursor: pointer'><b>" & rsData("Title") & "</b></td></span><td align='right' style='color: #000'>" & rsData("Cat") & " <a href='#' onclick='editUser("& rsData("ID") &")' language='vbscript'><img src='images/arrow-blue.png' border='0' title='Rediger notatet' /></a> <a href='#' onclick='deleteUser("& rsData("ID") &")' language='vbscript'><img src='images/slet.png' border='0' title='Slet notatet' /></a></td><tr><span class='toggle' style='display: block'><td colspan='2'>" & rsData("Notes") & "</td></span></tr></table>"
rsData.moveNext ' go to next record
Loop
strHTML2 = strHTML2 & ""
searchIT.innerHTML = strHTML2
end sub
我正在使用这个JS脚本来运行它：
I am using this JS script to run it:
<script type="text/javascript">
$(document).ready(function () {
$('.toggle').hide();
$('span.togglelink').on('click', function (e) {
e.preventDefault();
var elem = $(this).next('.toggle')
$('.toggle').not(elem).hide('fast');
elem.toggle('fast');
});
});
</script>
在使用纯文本进行测试时，我可以轻松地使用脚本。
JSFiddle
I can easily get the script to work when testing with just plain text. JSFiddle
提问：HTA中的编程与HTML真的如此不同吗？我在尝试将整个站点（MySQL，PHP，HTML）转换为HTA工作时遇到了很多问题。
Side question: Is programming in a HTA really so different from HTML? I'm running in to a lot of problems trying to convert my whole site (MySQL, PHP, HTML) to working in HTA.
提前致谢！
更新：列出我的整个.hta脚本：

推荐答案
div.togglelink <文件加载后将附加/ code>， -handler上的只会对文档加载时出现的元素产生影响。
The div.togglelink's will be attached after the document has been loaded, your on-handler will only have an effect to elements that are present when the document loads.
将处理程序附加到正文：
Attach the handler to the body instead:
$('body').on('click','span.togglelink',function(){/*your callback*/});
