问题 I get Atom data through Ajax using jQuery. I write $(xhr).find('entry id').eq(0).html(); is OK. But $(xhr).find('entry title').eq(0).html(); can not select anything. title tag is actually exist. Please help. Thank you! 回答1: That is because there is no title element in the Atom XML. The actual name is atom:title if the XML namespace http://www.w3.org/2005/Atom was mapped to the namespace prefix atom . Your problem is that jQuery is a HTML library, not an XML library. Therefore, it has some

Android Menu Item Title not displaying

大兔子大兔子 提交于 2020-01-02 03:36:28
问题 I've been fiddling with android, and I've been following the menu sample, and it runs almost fine, but the "title" field of the menu items isn't displaying. I think it's related to this question: https://stackoverflow.com/questions/3286093/android-menu-item-not-showing-text but I'm not sure what his answer means. Anyway, it properly gets that I have 2 menu items, it just isn't displaying the text. I'm not quite sure where the error is and figured extra sets of eyes would be good. XML: <?xml

JQuery操作DOM总结

一、元素的属性操作: 1、通过attr(name)方法获取元素的属性 eq: var strAlt = $("img").attr("src"); strAlt += "<br/><br/>" + $("img").attr("title"); //获取src和title属性值 2、设置元素的属性 语法:attr(key,value); attr(key0:value0,key1:value1); eq:$("img").("src","Images/img01.jpg"); $("img").("src","Images/img01.jpg","title","这是一封风精华“); 3、删除元素的属性: $("img").removeAttr("src"); 二、元素内容操作: 1、操作元素内容的方法有两种: (1)html()与Javascript 的innerHTML 类似(用于获取或设置元素的HTML内容);获取的不只包括文本内容还包括内部的div (2)text()与Javascript 的innerText类似(用于获取或设置元素的文本内容); 获取包括文本内容 var strHTML = $("#divShow").html(); var strText = $("#divShow").text(); $("#divHTML").html(strHTML); $("

你可能不知道的CSS 计数器

╄→尐↘猪︶ㄣ 提交于 2019-12-29 11:50:22
前言 CSS 里面的伪元素其实是非常好用的,但是经常容易被大家忽略,伪元素里面常用到的 content 属性,可能现在很多人仅仅以为 content 属性的值只支持字符串,除了字符串外常用到的还有 uri 、 counter ,今天所要介绍的就是 conter(计数器)。 先看如下的例子: <div> <h3>桃翁</h3> <h3>介绍</h3> <h3>css 计数器</h3> </div> 根据如上的 HTML 你是否有办法不通过 JavaScript ,仅仅用 CSS 在 title 前面增加 Title number: 呢? CSS 计数器基本概念 如果仅仅增加一个 Title ,大家都知道通过伪元素(:before或者:after),设置 content 为 Title,但是如何自动根据 h3 出现的顺序来展示自动编号可能很多人就不知道了。 自动编号在 CSS 2.1 中是通过两个属性控制的, 'counter-increment' 和 'counter-reset' 。通过这些属性定义的计数器用于 'content’ 属性的 counter() 和 counters() 函数 初始化计数器 在使用计数器的时候需要先初始化这个计数器,并且设置一个计数器的名字(变量)。下面是例子,title 就是名字,conter-reset 就是用来初始化的,这个属性是必须设置的
