有没有办法获得扩展/折叠TreeView节点的状态?(Is there a way to get the state of which TreeView nodes are expanded/collapsed?)
有没有办法获得扩展/折叠TreeView节点的状态?(Is there a way to get the state of which TreeView nodes are expanded/collapsed?)
此代码示例演示如何在ScrollViewer中使用ScrollToVerticalOffset获取滚动条的位置,以便例如,如果需要重新创建滚动条,可以将滚动条重置为此位置。
有没有办法为TreeView控件执行此操作,即获取用户已扩展的节点索引的集合?
This code example shows how to get the position of the scrollbar in a ScrollViewer (with ScrollToVerticalOffset) so that e.g. you can reset the scrollbar to this position if you need to recreate it.
Is there any way to do this for a TreeView control, i.e. get a collection of node indexes which the user has expanded?

这个问题你不需要JS。 您只需要扩展您的CSS:
#ctrl_mm_e_0_0 {background-image: url(dashboard.png)} #ctrl_mm_e_0_0:hover {background-image: url("dashboard_hover.png")} html[lang="ms"] #ctrl_mm_e_0_0 {background-image: url("dashboard_ms.png")} html[lang="ms"] #ctrl_mm_e_0_0:hover {background-image: url("dashboard_ms_hover.png")}
You don't need JS for this issue. All you need is to extend your CSS:
#ctrl_mm_e_0_0 {background-image: url(dashboard.png)} #ctrl_mm_e_0_0:hover {background-image: url("dashboard_hover.png")} html[lang="ms"] #ctrl_mm_e_0_0 {background-image: url("dashboard_ms.png")} html[lang="ms"] #ctrl_mm_e_0_0:hover {background-image: url("dashboard_ms_hover.png")}

将图像的url通过参数传递给您的函数:如果图像是PNG ,则可以直接在图像中包含alpha。 当然这需要IE6的PNG Fix脚本。 否则,您可以使用CSS来设置透明度。 编辑:更新为仅在悬停时工作,请注意这在IE6中不起作用。 img.transparent{ filter: alpha(opacity=100); /* internet explorer */ opacity: 1; /* fx, safari, opera, chrome */ } img.transparent:hover { ...$(document).ready(function () { $(".boxy").hover(function () { $("body").css('backgroundImage', 'url(img/2.JPG)'); }, function () { $("body").css('backgroundImage', 'url(img/1.JPG)'); }); }); jsFiddle示例 $(document).ready(functi ...回调hover()函数已经是this (jQuery元素对象引用)的好朋友,所以你只需要撤销$(this) function onHoverIn() { $(this).css('background-color', 'rgba(193, 86, 10, 0.86)'); } function onHoverOut() { $(this).css('background-color', 'rgba(26, 13, 3, 0.26)'); } $("button").hover(onHoverIn ...使用CSS在悬停时更改图像?(Change Image on Hover with CSS?)[2023-10-25]
