Remove annotations containing a title equal/not equal to a String?

由 柔情痞子 提交于 2019-12-06 05:42:59
I have looked for a couple of days on trying to remove annotations that a title equal or not equal to a string that is selected from a uicollection View cell didSelect from another view controller. I get the string passed to my view controller that contains my mapview. I use a custom annotation that is the model for how the annotations are displayed. How do I select and remove the custom annotations by their title. I already have an array of dictionaries that contains the data the annotations will use once the other annotations are removed. I know how to remove ALL the annotations, but not how

mybatis笔记

目录 mybatis中if test 的坑 mybatis笔记！ 参考文献： Mybatis if 判断等于一个字符串 mybatis中if test 的坑 if 判断等于一个字符串 <if test="title=='1'"> AND title = #{title,jdbcType=VARCHAR} </if> mybatis是使用的OGNL表达式来进行解析的，在OGNL的表达式中，'1'会被解析成字符，因为java是强类型的，char 和 一个String 会导致不等。所以if标签中的sql不会被解析。 如上写法，'1' 是一个char类型，它在内存中占一个字节，它通过它的ASC||码值参与运算 ，1的ACS||码值是49 ，当传入49时test通过，当传入非数字字符时，如's'则会mybatis报错类型异常 Error querying database. Cause: java.lang.NumberFormatException: For input string: "s" 解决方法： 如果是数字，可以直接数值比较 <if test="title==1"> AND title = #{title,jdbcType=VARCHAR} </if> 如果是单字符，则使用双引号表示字符串，上面的数值也适用（推荐做法） <if test='title=="y"'> AND

UINavigationController 和 UITabBarController（非基础使用，测试一下思路）

1、viewController都有nav 2、nav.root=TabBarController 各个viewController 的区别 第一种 每个viewControll对应一个navigationcontroller let firstVC=IndexViewController(); let nav1=UINavigationController(rootViewController:firstVC); let image1=UIImage(named:"a"); nav1.tabBarItem=UITabBarItem(title:"aaa",image:image1,tag:1); let secondVC=IndexViewController(); let nav2=UINavigationController(rootViewController:secondVC); let image2=UIImage(named:"b"); nav2.tabBarItem=UITabBarItem(title:"bbb",image:image2,tag:2); let thirdVC=IndexViewController(); let nav3=UINavigationController(rootViewController:thirdVC); let image3

二、jQuery中的DOM操作

Dom操作的分类 一般来说，Dom操作分为3个方面，即DOM Core、HTML-DOM和CSS-DOM。 jQuery中的DOM操作 一、查找节点 用jQuery在文档树上查找节点非常容易，可以利用前面介绍的jQuery选择器来完成。 1、查找元素节点 利用jQuery选择器 <script type="text/javascript"> $(function(){ //获取第二个li元素 var $li=$('ul li:eq(1)'); var li_txt=$li.text(); alert(li_txt); }); </script> <p title="选择你最喜欢的水果." >你最喜欢的水果是?</p> <ul> <li title='苹果'>苹果</li> <li title='橘子'>橘子</li> <li title='菠萝'>菠萝</li> </ul> 2、查找属性节点 利用jQuery选择器查找到需要的元素之后，就可以使用attr()方法来获取它的各种属性的值。attr()方法的参数可以是一个，也可以是两个。当参数是一个时，则是要查询的属性的名字。 //获取p元素 var $p=$('p'); var p_title=$p.attr('title'); //获取<p>元素节点的属性title alert(p_title); 二、创建节点 1、创建元素节点：

问题 I'm helping with an effort to upgrade a very old corporate intranet. Our users are on IE8 and IE9. Most of our sites are written to work in IE5 - IE9. We're on the verge of upgrading everyone to IE11, and pilots are finding a ton of compatibility issues. There will be a great deal of remediation in the months ahead, as well as judicious use of Enterprise Mode, Compatibility Modes, X-UA tags, and so on. But I've encountered one strange problem that doesn't make any sense. It seems like a bug,

How to resize callout bubble after resetting title/subtitle

由 早过忘川 提交于 2019-12-05 21:18:02
I created an MKAnnotation name PushPin which has a title and subtitle. I want to be able to dynamically change the title at a later time. I'm close so I'd rather not have to make a whole new AnnotationView, but if I have to I guess that's ok too. My problem is that, once I change the text for the title, the window does not resize and some text might get cut off depending on how big the title originally was. 1) Is there an event I can trigger to resize the callout bubble window again? 2) Also, I check to make sure that the annotation actually has a title first before I go resetting the title,

“alt” attribute on images and “title” attribute on links required in HTML5?

由 独自空忆成欢 提交于 2019-12-05 17:36:50
Me and other developers at our company are struggling with "title" and "alt" attributes. In the past, we added "title"-Tags to all links for SEO purposes (although some of them were annoing talking about usability) and "alt"-Tags on every image on the site, because HTML4 spec said so. Are "title" and "alt"-Tags still required ? If they're not required, do they still have effects on SEO? unor Check the HTML specification to see what is/isn’t required: a element : The ( global ) title attribute is not required. img element : The alt attribute is required in most cases ( exceptions ).

Title Attribute on Disabled Elements in Firefox

I am building a very dynamic web-based application using a lot of Javascript to handle user events. I am in the process of making things a little more usable and came across a problem that I've never had before. I am using jQuery, so factor that in to your answers. Thanks in advance. I have a set of button elements defined as: <input type="button" title="My 'useful' text here." disabled="disabled" /> I have these buttons with a default style of: div#option_buttons input { cursor: help; } Then, using jQuery I run something like this as a click-event on a select box: window.current_column = '';
