DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

1. childNodes nodeValue

<p >hello p!</p>

alert(document.getElementById("p1").childNodes[0].nodeValue);

2. firstChild lastChild

childNodes[0] 等价于 firstChild (node.childNodes[0] == node.firstChild)

node.childNodes[node.childNodes.length-1] 等价于 node.lastChild

3. nodeValue 赋值

　　var description = document.getElementById("p1");

description.firstChild.nodeValue = text;

4. nodeType

nodeType共有12中可取值，只有三种具有实用价值

·元素节点的nodeType值为1

属性节点的 nodeType值为2

文本节点的nodeType值为3

5. window.open(url, windowName, features)

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

<a href="javascript:popUp('http://www.baidu.com');">hehehehe</a>//伪协议

function popUp(winURL){
window.open(winURL, "mywindow", "width=110, height=222");
}

6. 平稳退化

<a href="http://www.baidu.com" onClick="popUp(this.href);return false;">hehehehe</a>

7. 分离javascript

var links = document.getElementsByTagName("a");

for(var i=0; i<links.length; i++){

　　if(links[i].getAttribute("class")==="popup"){

　　links[i].onclick = function(){

　　　　　　popUp(this.getAttribute("href"));

　　　　　　return false;

}　　

</script>

8. document对象是wndow对象的一个属性，当window对象触发onload事件时，document对象已经存在

9.对象检测

if(!document.getElementsByTagName)return false;

10 合并和放置脚本浏览器同时下载文件的数量有限

11 压缩脚本去掉注释空格等

脚本文件应该有两个版本一是工作副本，可以修改代码并添加注释；一是精简副本(文件名中通常加上min example.min.js)，用于放在站点上

代码压缩工具谷歌Closure compiler

12. window.onload绑定事件

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

改进;

然后调用

addLoadEvent(firstFunction);

addLoadEvent(secondFunction);

13. nodeName 该属性总是返回一个大写字母的值

var mypic = document.getElementById("mypic");

if(mypic.nodeName!="IMG")return false;

14. onkeypress键盘事件

可以使用 links[i].onkeypress = links[i].onclick;把onclick事件的所有功能赋给onkeypress

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

15 innerHTML 属性无细节可言，要想获得细节需要用dom的方法和属性；类似于document.write, innerHTML也是HTML专有属性

testdiv.innerHTML = "<p>i am <em>a </em>teacher</p>";

16 dom方法

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

17. createElement 只能创建元素节点

var para = document.createElement("p");

alert(para.nodeName);

alert(para.nodeType);

18 appendChild

var testdiv = document.getElementById("testdiv");

testdiv.appendChild(para);

19. createTextNode 创建文本节点

var text = document.createTextNode("hello js");

para.appendChild(text);

20. DOM insertBefore()

parentElement.insertBefore(newElement, targetElement);

我们不必搞清楚父元素是哪个 targetElement元素的parentNode属性就是它

21 insertAfter

22. Ajax XMLHttpRequest

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

创建XMLHttpRequest对象

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

XMLHttpRequest open()方法

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

访问服务器返回的数据

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

注意

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

23 Hijax 渐进增强的使用ajax

正常的登录使用form表单触发submit事件，只要使用onsubmit事件处理函数捕获该事件，就可以取消他的默认操作(提交整个页面)

然后通过XMLHttpRequest对象向服务器发送请求。

24. 两点原则

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

25. 缩略语标签abbr

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

26. DOCTYPE 标准模式

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

27. 从abbr标签读取title并按照定义列表(dl)方式展示

function displayAbbreviations(){
    var abbreviations = document.getElementsByTagName("abbr");
    if(abbreviations.length < 1)return false;
    var defs = new Array();
    for(var i=0; i<abbreviations.length; i++){
        var current_abbr = abbreviations[i];
        var description = current_abbr.getAttribute("title");
        var key = current_abbr.lastChild.nodeValue;
        defs[key] = description;
    
    }
    var dlist = document.createElement("dl");
    for(key in defs){
        var dtitle = document.createElement("dt");
        var dtitle_text = document.createTextNode(key);
        dtitle.appendChild(dtitle_text);
        
        var ddesc = document.createElement("dd");
        var ddesc_text = document.createTextNode(defs[key]);
        ddesc.appendChild(ddesc_text);
        
        dlist.appendChild(dtitle);
        dlist.appendChild(ddesc);
        
    }
    var header = document.createElement("h2");
    var header_text = document.createTextNode("Abbreviations");
    header.appendChild(header_text);
    document.body.appendChild(header);
    document.body.appendChild(dlist);
}

28. CSS DOM要求用驼峰命名

element.style.font-family报错应使用 element.style.fontFamily

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

29. 获取下一个元素节点

function getNextElement(node){
  if(node.nodeType==1){
     return node;
  }  
  if(node.nextSibling){
     return getNextElement(node.nextSibling);
  }
  return null;
}

30. 表格奇数偶数行斑马色

function stripTables(){
 var tables = document.getElementsByTagName("table");
 var odd, rows;
 for(var i=0; i<tables.length; i++){
    odd = false;
    rows = tables[i].getElementsByTagName("tr");
    for(var j=0; j<rows.length; j++){
        if(odd==true){
            rows[j].style.backgroundColor = "#ffc";
            odd = false;
        }else{
            odd = true;
        }
    }
 }
}

31. css :hover伪类

如果只想鼠标悬停在链接、表格行上时改变颜色、字体等，可以使用css ：hover

<head>
<style>
tr:hover{
        font-weight : bold;
    }
</style>
</head>

使用js同样实现

function highlightRows(){
 var rows = document.getElementsByTagName("tr");
 for(var i=0; i<rows.length; i++){
    rows[i].onmouseover = function(){
        this.style.fontWeight = "bold";
    };
    rows[i].onmouseout = function(){
        this.style.fontWeight = "normal";
    }
 }
}

32. 可以通过js给标签赋予某class值再在css中对该class定义样式这样在更新时就可以避免修改js

element.className = "intro";

css中

.intro{

　　font-weight : bold;

font-size : 1.4em;

}

这个技巧有一个不足 element标签原来有一些样式时原样式会被覆盖添加addClass函数处理

function addClass(element, value){
    if(!element.className){
        element.className = value;
    }else{
        element.className += " " + value;
    }
}

javascript现在更新的是className属性，根本没碰style，分离更彻底

33. setTimeout函数能够让某个函数在经过一个预定时间之后运行

var variable;

variable = setTimeout('function', interval);

clearTimeout函数能够取消setTimeout中准备执行的函数

clearTimeout(variable);

34. parseInt(string) 返回一个数值

parseInt("39 step")将返回数值39 parseInt("50px")将返回50

parseFloat(string) 将返回浮点数

35. 图片在页面内定时更新位置实现动画效果

<!DOCTYPE html>
<html en="lang">
<head>
<meta charset="utf-8"/>
</head>
<body>
<img id="mypic" src="hellonodejs.png"/>
<script src="animation.js"></script>
</body>
</html>
---------animation.js---------
function moveMessage(){
    
    var elem = document.getElementById("mypic");
    var xpos = parseInt(elem.style.left);// pos.left
    var ypos = parseInt(elem.style.top);//style.top
    if(xpos==300 && ypos==300)return true;
    if(xpos<300) xpos++;
    if(xpos>300) xpos--;
    if(ypos<300) ypos++;
    if(ypos>300) ypos--;
    elem.style.left = xpos + "px";
    elem.style.top = ypos + "px";
    setTimeout(moveMessage, 10);
}
function initPos(){
  
  var elem = document.getElementById("mypic");
  //elem.className = "newstyle";
  elem.style.position = "relative";
  elem.style.left = "600px";
  elem.style.top = "200px";
}
function addLoadEvent(func){
  var oldonload = window.onload;
  if(typeof window.onload!='function'){
    window.onload = func;
  }else{
    window.onload = function(){
        oldonload();
        func();
    }
  }
}
addLoadEvent(initPos);
addLoadEvent(moveMessage);

36. 鼠标悬停于a链接图片切换

<!doctype html>
<html lang="zh">
<head>
    <meta charset="UTF-8">
    <title>testAnimation</title>
    <link href="b3.css" rel="stylesheet" type="text/css"/>
</head>

</body>
</html>

------------b3.css-------------
#previewdiv{
    position : absolute;
    width : 280px;
    height : 210px;
    overflow : hidden;
}

----------------b3.js---------------------
function moveMessage(elementID, final_x, final_y, interval){
    var elem = document.getElementById(elementID);
    var xpos = parseInt(elem.style.left);
    var ypos = parseInt(elem.style.top);
    if(xpos==final_x && ypos==final_y) return true;
    if(xpos<final_x) xpos++;
    if(xpos>final_x) xpos--;
    if(ypos<final_y) ypos++;
    if(ypos>final_y) ypos--;
    elem.style.left = xpos + "px";
    elem.style.top = ypos + "px";
    var repeat = "moveMessage('"+elementID+"', '"+final_x+"', '"+final_y+"', '"+interval+"')";
    movement = setTimeout(repeat, interval);
}



function positionMessage(){
  
  var elem = document.getElementById("scrollPic");
  elem.style.position = "relative";
  elem.style.left = "0px";
  elem.style.top = "0px";
  var olist = document.getElementById("olist");
var links = olist.getElementsByTagName("a");
links[1].onmouseover = function(){moveMessage("scrollPic", -280, 0, 10)};
links[2].onmouseover = function(){moveMessage("scrollPic", -560, 0, 10)};
links[3].onmouseover = function(){moveMessage("scrollPic", -840, 0, 10)};
  
}
function addLoadEvent(func){
  var oldonload = window.onload;
  if(typeof window.onload!='function'){
    window.onload = func;
  }else{

        oldonload();
        func();
    }
  }
}
addLoadEvent(positionMessage);

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

解决办法

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

代码

function moveMessage(elementID, final_x, final_y, interval){
    var elem = document.getElementById(elementID);
    if(elem.movement){
        clearTimeout(elem.movement);
    }
    var xpos = parseInt(elem.style.left);
    var ypos = parseInt(elem.style.top);
    if(xpos==final_x && ypos==final_y) return true;
    if(xpos<final_x) xpos++;
    if(xpos>final_x) xpos--;
    if(ypos<final_y) ypos++;
    if(ypos>final_y) ypos--;
    elem.style.left = xpos + "px";
    elem.style.top = ypos + "px";
    var repeat = "moveMessage('"+elementID+"', '"+final_x+"', '"+final_y+"', '"+interval+"')";
    elem.movement = setTimeout(repeat, interval);
}

优化效果

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

借助js函数

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

代码

var dist = 0;
    if(xpos < final_x) {
        dist = Math.ceil((final_x-xpos)/10);
        xpos += dist;
    };
    if(xpos > final_x) {
        dist = Math.ceil((xpos-final_x)/10);
        xpos -= dist;
    };
    if(ypos < final_y) {
        dist = Math.ceil((final_y - ypos)/10);
        ypos += dist;
    };
    if(ypos > final_y) {
        dist = Math.ceil((ypos - final_y)/10);
        ypos -= dist;
    };

37. 添加安全检查

这里elem的left样式属性和top样式属性可能不存在

DOM Scripting -- Web Design with JavaScript and the Document Object Model 第2版读书笔记

if(!elem.style.left){
   elem.style.left = 0px;   
}
if(!elem.style.top){
   elem.style.top = 0px;   

}

整理后的moveElement函数

function moveMessage(elementID, final_x, final_y, interval){
    var elem = document.getElementById(elementID);
    if(elem.movement){
        clearTimeout(elem.movement);
    }
    if(!elem.style.left){
        elem.style.left = "0px";
    }
    if(!elem.style.top){
        elem.style.top = "0px";
    }
    var xpos = parseInt(elem.style.left);
    var ypos = parseInt(elem.style.top);
    if(xpos==final_x && ypos==final_y) return true;
    var dist = 0;
    if(xpos < final_x) {
        dist = Math.ceil((final_x-xpos)/10);
        xpos += dist;
    };
    if(xpos > final_x) {
        dist = Math.ceil((xpos-final_x)/10);
        xpos -= dist;
    };
    if(ypos < final_y) {
        dist = Math.ceil((final_y - ypos)/10);
        ypos += dist;
    };
    if(ypos > final_y) {
        dist = Math.ceil((ypos - final_y)/10);
        ypos -= dist;
    };
    elem.style.left = xpos + "px";
    elem.style.top = ypos + "px";
    var repeat = "moveMessage('"+elementID+"', '"+final_x+"', '"+final_y+"', '"+interval+"')";
    elem.movement = setTimeout(repeat, interval);
}

如果用户禁用了javascript，那么上面展示动画的div和img就显得无用所以应该动态追加这两个标签

用到document.createElement insertAfter(自己实现)
