Javascript技巧参考大全

  1. 1. javascript 技巧参考大全• 事件源对象 event.srcElement.tagName event.srcElement.type• 捕获释放 event.srcElement.setCapture(); event.srcElement.releaseCapture();• 事件按键 event.keyCode event.shiftKey event.altKey event.ctrlKey• 事件返回值 event.returnValue• 鼠标位置 event.x event.y• 窗体活动元素 document.activeElement• 绑定事件 document.captureEvents(Event.KEYDOWN);• 访问窗体元素 document.all("txt").focus(); document.all("txt").select();• 窗体命令 document.execCommand• 窗体 COOKIE document.cookie• 菜单事件 document.oncontextmenu• 创建元素 document.createElement("SPAN");• 根据鼠标获得元素: document.elementFromPoint(event.x,event.y).tagName=="TD document.elementFromPoint(event.x,event.y).appendChild(ms)• 窗体图片 document.images[索引]• 窗体事件绑定 document.onmousedown=scrollwindow;• 元素 document.窗体.elements[索引]• 对象绑定事件 document.all.xxx.detachEvent(onclick,a);
  2. 2. • 插件数目 navigator.plugins• 取变量类型 typeof($js_libpath) == "undefined"• 下拉框 下拉框.options[索引] 下拉框.options.length• 查找对象 document.getElementsByName("r1"); document.getElementById(id);• 定时 timer=setInterval(scrollwindow(),delay); clearInterval(timer);• UNCODE 编码 escape() ,unescape• 父对象 obj.parentElement(dhtml) obj.parentNode(dom)• 交换表的行 TableID.moveRow(2,1)• 替换 CSS document.all.csss.href = "a.css";• 并排显示 display:inline• 隐藏焦点 hidefocus=true• 根据宽度换行 style="word-break:break-all"• 自动刷新 <meta HTTP-EQUIV="refresh" CONTENT="8;URL=http://c98.yeah.net">• 简单邮件 <a href="mailto:aaa@bbb.com?subject=ccc&body=xxxyyy">• 快速转到位置 obj.scrollIntoView(true)• 锚 <a name="first"> <a href="#first">anchors</a>• 网页传递参数 location.search();• 可编辑 obj.contenteditable=true• 执行菜单命令 obj.execCommand
  3. 3. • 双字节字符 /[^x00-xff]/ 汉字 /[u4e00-u9fa5]/• 让英文字符串超出表格宽度自动换行 word-wrap: break-word; word-break: break-all;• 透明背景 <IFRAME src="1.htm" width=300 height=180 allowtransparency></iframe>• 获得 style 内容 obj.style.cssText• HTML 标签 document.documentElement.innerHTML• 第一个 style 标签 document.styleSheets[0]• style 标签里的第一个样式 document.styleSheets[0].rules[0]• 防止点击空链接时,页面往往重置到页首端。 <a href="javascript:function()">word</a>• 上一网页源 asp: request.servervariables("HTTP_REFERER") javascript: document.referrer• 释放内存 CollectGarbage();• 禁止右键 document.oncontextmenu = function() { return false;}• 禁止保存 <noscript><iframe src="*.htm"></iframe></noscript>• 禁止选取<body oncontextmenu="return false" ondragstart="return false" onselect start ="return false" onselect="document.selection.empty()" oncopy="document. selection.empty()" onbeforecopy="return false"onmouseup="document.selection. empty()>• 禁止粘贴 <input type=text onpaste="return false">• 地址栏图标 <link rel="Shortcut Icon" href="favicon.ico"> favicon.ico 名字最好不变 16*16 的 16 色,放虚拟目录根目录下• 收藏栏图标 <link rel="Bookmark" href="favicon.ico">• 查看源码 <input type=button value=查看网页源代码 onclick="window.location = view- source:+ http://www.csdn.net/">
  4. 4. • 关闭输入法 <input style="ime-mode:disabled">• 自动全选 <input type=text name=text1 value="123" onfocus="this.select()">• ENTER 键可以让光标移到下一个输入框 <input onkeydown="if(event.keyCode==13)event.keyCode=9">• 文本框的默认值 <input type=text value="123" onfocus="alert(this.defaultValue)">• title 换行 obj.title = "123 sdfs "• 获得时间所代表的微秒 var n1 = new Date("2004-10-10".replace(/-/g, "/")).getTime()• 窗口是否关闭 win.closed• checkbox 扁平 <input type=checkbox style="position: absolute; clip:rect(5px 15px 15px 5px)"><br>• 获取选中内容 document.selection.createRange().duplicate().text• 自动完成功能 <input type=text autocomplete=on>打开该功能 <input type=text autocomplete=off>关闭该功能• 窗口最大化 <body onload="window.resizeTo(window.screen.width - 4,window.screen.height-50);window.moveTo(-4,-4)">• 无关闭按钮 IE window.open("aa.htm", "meizz", "fullscreen=7");• 统一编码/解码 alert(decodeURIComponent(encodeURIComponent("http://你好.com?as= hehe"))) encodeURIComponent 对":"、"/"、";" 和 "?"也编码• 表格行指示 <tr onmouseover="this.bgColor=#f0f0f0" onmouseout="this.bgColor=#ffffff"> //各种尺寸s += "rn 网页可见区域宽:"+ document.body.clientWidth; s += "rn 网页可见区域高:"+ document.body.clientHeight; s += "rn 网页可见区域高:"+ document.body.offsetWeight +" (包括边线的宽)"; s += "rn 网页可见区域高:"+ document.body.offsetHeight +" (包括边线的宽)"; s += "rn 网页正文全文宽:"+ document.body.scrollWidth;
  5. 5. s += "rn 网页正文全文高:"+ document.body.scrollHeight;s += "rn 网页被卷去的高:"+ document.body.scrollTop;s += "rn 网页被卷去的左:"+ document.body.scrollLeft;s += "rn 网页正文部分上:"+ window.screenTop;s += "rn 网页正文部分左:"+ window.screenLeft;s += "rn 屏幕分辨率的高:"+ window.screen.height;s += "rn 屏幕分辨率的宽:"+ window.screen.width;s += "rn 屏幕可用工作区高度:"+ window.screen.availHeight;s += "rn 屏幕可用工作区宽度:"+ window.screen.availWidth; //过滤数字 //特殊用途 //不缓存//正则匹配匹配中文字符的正则表达式: [u4e00-u9fa5]匹配双字节字符(包括汉字在内):[^x00-xff]匹配空行的正则表达式:n[s ]*r匹配 HTML 标记的正则表达式:/<(.*)>.*</1><(.*) />/匹配首尾空格的正则表达式:(^s*)(s*$)(像 vbscript 那样的 trim 函数)匹配 Email 地址的正则表达式:w+([-+.]w+)*@w+([-.]w+)*.w+([-.]w+)*匹配网址 URL 的正则表达式:http://([w-]+.)+[w-]+(/[w- ./?%&=]*)?以下是例子:利用正则表达式限制网页表单里的文本框输入内容:用正则表达式限制只能输入中文:onkeyup="value=value.replace(/[^u4E00-u9FA5]/g,)" onbeforepaste="clipboardData.setData(text,clipboardData.getData(text).replace(/[^u4E00-u9FA5]/g,))"1.用正则表达式限制只能输入全角字符: onkeyup="value=value.replace(/[^uFF00-uFFFF]/g,)" onbeforepaste="clipboardData.setData(text,clipboardData.getData(text).replace(/[^uFF00-uFFFF]/g,))"2.用正则表达式限制只能输入数字:onkeyup="value=value.replace(/[^d]/g,)"onbeforepaste="clipboardData.setData(text,clipboardData.getData(text).replace(/[^d]/g,))"3.用正则表达式限制只能输入数字和英文:onkeyup="value=value.replace(/[W]/g,)"onbeforepaste="clipboardData.setData(text,clipboardData.getData(text).replace(/[^d]/g,))" //消除图像工具栏<IMG SRC="mypicture.jpg" HEIGHT="100px" WIDTH="100px" GALLERYIMG="false">or<head>
