label

Can a label only refer to input elements?

问题 W3Schools have this to say about labels: The <label> tag defines a label for an input element. [Emphasis mine] Does this mean that the following HTML isn't valid? <!doctype html> <html> <head> <title>Example document</title> </head> <body> <label for="x">Label</label> <hr> <div id="q" contentEditable="true">Hello</div> <hr> <div id="x" contentEditable="true">World</div> </body> </html> Both Chrome and IE8 give focus to World when Label is clicked, Firefox does not. Which is correct? 回答1:

Plot series of boxplots using base graphics in R

由 女生的网名这么多〃 提交于 2019-12-21 03:21:09
问题 I would like to plot multiple boxplots in R in a single graph and group them by pairs. I am a beginner in R and although several threads deal with the same subject (multiple boxplots in R ), I could not find a comprehensive way to to this. I would like to use base graphics only if possible. I have 10 sets of values, all of them containing 30 values (which can be any positive value). Within those 10 sets, 5 are of type 1 and the 5 other are of type 2. My objective is to have ten boxplots (one

问题 When manually adding a contact's phone / IMS in the iOS AddressBook, you can add a Custom Label instead of "Home", "Work", "Other" * (in IMS). How to create "Custom Label" in AddressBook programmatically? 回答1: I had this exact same question. I couldn't find an answer so I just tried the guess and check method. The following code seems to work: CFErrorRef error = NULL; ABAddressBookRef iPhoneAddressBook = ABAddressBookCreate(); ABRecordRef newPerson = ABPersonCreate(); ABRecordSetValue

AutoLayout~Label

由 杀马特。学长 韩版系。学妹 提交于 2019-12-21 01:11:29
使用Autolayout可以不用计算文字的宽高，直接给label赋值，label会自己适应文字的长度调节宽高 如果你像下图一样限定了label的topMargin和左右边距 下边距设置为>=300 然后在ViewDidLoad里面重新给label设置内容，这时候你会发现，Label会自动变高 dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{ _label.text = @"aaaaaaaaaaaasfeaqrgrthrwthwrtyjhwryjwryjwryjwryjwryjwryjwryjwrytjwryjwrytjwrytjwrtjwrtyjwrtjwrtjqwrtjwrtjhwrtjhetjrthjqwrthjqrthqrthjqrtjhqrtjhqarthjqethjteqathqtehqthqathqrthqrtjhq"; }); 此外Label还提供了一个属性preferredMaxLayoutWidth 用来获取计算文本高度是所用的宽度，如果这个属性没有设置就会按照autoLayout里的设置来计算 如果这个属性重新设置了值，就会使用这个值来计算label要变成的高度 将上面的代码改成下面的代码

CSS属性（float、position）

一、float属性 1、基本属性 先来了解一下block元素和inline元素在文档流中的排列方式。 　　block元素通常被现实为独立的一块，独占一行，多个block元素会各自新起一行，默认block元素宽度自动填满其父元素宽度。block元素可以设置width、height、margin、padding属性； 　　inline元素不会独占一行，多个相邻的行内元素会排列在同一行里，直到一行排列不下，才会新换一行，其宽度随元素的内容而变化。inline元素设置width、height属性无效 常见的块级元素有 div、form、table、p、pre、h1～h5、dl、ol、ul 等 。 常见的内联元素有span、a、strong、em、label、input、select、textarea、img、br等。 所谓的文档流 ，指的是元素排版布局过程中，元素会自动从左往右，从上往下的流式排列。 脱离文档流 ，也就是将元素从普通的布局排版中拿走，其他盒子在定位的时候， 会当做脱离文档流的元素不存在而进行定位 。 假如某个div元素A是浮动的，如果A元素上一个元素也是浮动的，那么A元素会跟随在上一个元素的后边(如果一行放不下这两个元素，那么A元素会被挤到下一行)；如果A元素上一个元素是标准流中的元素，那么A的相对垂直位置不会改变，也就是说A的顶部总是和上一个元素的底部对齐。此外

问题 I have a label on my form which is on the right of the form. This label loads a dynamic text.
