问题 I try to extract all the text content of a page (because it doesn't work with Simpledomparser) I try to modify this simple example from the manual var page = require('webpage').create(); console.log('The default user agent is ' + page.settings.userAgent); page.settings.userAgent = 'SpecialAgent'; page.open('http://www.httpuseragent.org', function (status) { if (status !== 'success') { console.log('Unable to access network'); } else { var ua = page.evaluate(function () { return document

Dom节点操作常用方法

1.访问/获取节点 document.getElementById(id);           //返回对拥有指定id的第一个对象进行访问 document.getElementsByName(name);      //返回带有指定名称的节点集合   注意拼写:Elements document.getElementsByTagName(tagname);   //返回带有指定标签名的对象集合  注意拼写:Elements document.getElementsByClassName(classname); //返回带有指定class名称的对象集合 注意拼写:Elements 2.创建节点/属性 document.createElement(eName);  //创建一个节点 document.createAttribute(attrName); //对某个节点创建属性 document.createTextNode(text);   //创建文本节点 3.添加节点 document.insertBefore(newNode,referenceNode);  //在某个节点前插入节点 parentNode.appendChild(newNode);        //给某个节点添加子节点 4.复制节点 cloneNode(true | false);  //复制某个节点 参数

Append HTML-escaped text: jQuery

痞子三分冷 提交于 2020-01-20 05:03:08
问题 I'm used to using jQuery's .append() method to add text or HTML onto the end of a pre-existing element. I'm currently using jQuery's .text() to escape strings that could potentially contain HTML. Unfortunately, there doesn't seem to be a jQuery method that will append the results of the .text() method to an element instead of replacing its contents. Is there a way to append, instead of replace, this escaped text to an element? Or is there a better way to escape strings containing HTML? Thanks

Accessing DOM from WebBrowser

我怕爱的太早我们不能终老 提交于 2020-01-20 04:24:25
问题 I am trying to implement a browser-like little application that would allow me to modify the viewed web-sites appearance (e.g. make the font for links bigger). It is designed for Microsoft Surface, to be used on a huge touchscreen. It uses WPF for the UI. I am intending to use a WebBrowser control for this task. However there are two classes called WebBrowser in the docs. One of them is in System.Windows.Forms , the other in System.Windows.Controls . The first one gives access to DOM model,

DOM介绍:文档对象模型 为了方便javascript语言通过dom操作html比较方便; HTML中节点分类: 1.文档节点(document) 2.元素节点 3.文本节点 4.属性节点 5.注释节点 节点的选择 1.document.getElementById(id属性值); 2.document.getElementsByTagName(tag标签名称); 3.document.getElementsByName(name属性值);不推荐 注:1.收集的元素都是以字符串的形式返回的 获得文本节点的方法(Nodes:节点) var dd = document.getElementsByTagName(‘div’)[0]; firstChild、lastChild:父节点获得第一个/最后一个子节点 nextSibling:获得下个兄弟节点 previousSibling:获得上个兄弟节点 childNodes:父节点获得内部全部的子节点信息 获取属性值 1. 获取属性值 itnode.属性名称; itnode.getAttribute(属性名称); 2.设置属性值 itnode.属性名称 = 值; itnode.setAttribute(名称,值); 属性节点的获取 var attrlist = itnode.attributes; attrlist.属性名称; 节点的创建

Can I move a Flash object within the DOM without it reloading?

只愿长相守 提交于 2020-01-20 04:02:04
问题 I'm trying to use the scale effect from the jQuery UI library on a wrapper element that contains a Flash object. The problem I'm encountering is that the content of my wrapper is automatically moved into another wrapper ( .ui-effects-wrapper ), and when this happens the Flash object reloads. Of course, the specific problem here has to do with the tactic employed by jQuery UI — but generally, is it possible to move a Flash object within the DOM without it reloading? 回答1: I only know how this

DOM的理解与应用

DOM 为了方便javascript语言通过dom操作html比较方便。 把html标签的内容划分为各种节点: 文档节点(document)-----body 元素节点-----标签 文本节点-----内容 属性节点 注释节点 获取元素节点(标签) 通过id获取: document.getElementById(id属性值); 通过标签名来获取: document.getElementsByName(标签名称); //可获取多个标签 通过name属性获取: document.getElementsByName(name属性值); 通过class获取: document.getElementsByClassName(class属性值);(不推荐) 注:收集的元素都是以字符串的形式返回的 获取文本节点(Nodes:节点) var dd = document.getElementsByTagName('div')[0]; 获取兄弟节点: firstChild、lastChild:父节点获得第一个/最后一个子节点 nextSibling:获得下个兄弟节点 previousSibling:获得上个兄弟节点 childNodes:父节点获得内部全部的子节点信息 获取父节点 节点.parentnode 操作内容 非表单标签:标签对象.innerHTML ="123"; 表单标签: 标签对象
