问题 I'm fairly new to javascript and have been unable to get this code to work and I am unsure were and what I'm missing. So here is what I want it to do. I'm trying to have the script read everything and switch the visibility of the span found in the body <body> <span hidden>A</span> <span>X</span> <span hidden>B</span> <span>Y</span> <span hidden>C</span> <span>Z</span> </body> So instead of reading 'X Y Z' it will display 'A B C' The code I have so far is.. $(function() { var elems = document

问题 I have a macro that opens the Internet Explorer Dim IE As Object Set IE = CreateObject("InternetExplorer.Application") IE.Visible = True Later the macro interacts with other windows, so the IE loses the focus. But, after the other interactions, I need to send keys to the IE application. I searched how to activate again the IE Window, but none worked. I tried (1) Declare Function SetForegroundWindow Lib "user32" (ByVal hwnd As Long) As Long Public Sub test() Set acObj = GetObject(,

How to add visibility binding for MenuItem of ContextActions of a ListView

由 随声附和 提交于 2020-03-03 09:09:11
问题 I am trying display context actions menu items while selecting any listview item, there I have added three menu items. But I need to bind the visibility for those Menu Items. Depending on selection the specific menuitem should be visible. Is there any way to add binding for the contextActions menuitems in a listview? 回答1: Since a ContextAction is a MenuItem this is not possible. The MenuItem does not expose any (bindable) IsVisible property or alike. A hacky workaround could be to add/remove

CSS中如何隐藏DOM节点

今晚注定是个不眠夜呀，手贱的同学又要送上一则小文，来分享分享 一： 我们在想对如何隐藏节点这个问题上有所建树的话，那么我们就必须要先知道浏览器渲染引擎的基本工作原理，现在渲染引擎主力军有 （ Firefox使用Gecko —— Mozilla自家的渲染引擎；Safari 和 Chrome 使用 Webkit。Webkit是一种开源的渲染引擎 ）。 渲染的基本流程： 解析HTML构建DOM树——构建渲染树——渲染树布局——绘制渲染树。 如果亲你不知道，请关注这个连接有所介绍： http://ued.ctrip.com/blog/?p=3295 二： 完成上面的脑补之后就可以说说我们的隐藏节点了。有两个CSS语句能起到隐藏节点的作用 1、visibility； W3c定义的是规定了元素的是否可见，值得注意的是在下面提示部分有一句话说：即使不可见也会占用上面的空间，在这里就是在指它与display的不一样了 2、display； W3C在说明这个属性的时候是比较客观的，这个属性用于定义建立布局时元素生成的显示框类型。对于 HTML 等文档类型，如果使用 display 不谨慎会很危险，因为可能违反 HTML 中已经定义的显示层次结构。对于 XML，由于 XML 没有内置的这种层次结构，所有 display 是绝对必要的。 3、对比这两个他们都有相同的功能就是隐藏

Kotlin instance variable is null when accessed by Spring proxied class

由 点点圈 提交于 2020-02-26 14:18:52
问题 I have a service class that is being proxied by Spring, like so: @Service @Transactional open class MyService { ... } If I remove the open modifier, Spring complains that it needs to proxy the class to apply the @Transactional annotation tweaks. However, this is causing issues when calling a function on the proxied service, which attempts to access a variable: @Service @Transactional open class MyService { protected val internalVariable = ... fun doWork() { internalVariable.execute() //
