Visual Studio 2010 Web项目的jQuery版本升级方案

衣明志 — Tue, 11 May 2010 05:13:35 GMT

我们知道在Visual Studio 2010的非空Web项目(含Webform和MVC)中，都自动包含了jQuery库在项目的Scripts文件夹中。

但细心的人们都看到了正式版中包含的jQuery版本是1.4.1版，而不是jQuery官方最新发布的1.4.2版。处于新版效率的极大提升以及部分bug的修复，推荐大家跟新使用1.4.2版，而放弃1.4.1版。单个项目的调整比较简单就是把旧版本的删除，然后添加上1.4.2版的相应文件即可。但我们很多人可能更希望是以后创建的项目都是1.4.2版而不是1.4.1版，怎么办呢？我在相关的webcast中有提到过，即到vs2010的安装目录中修改项目模板的有关文件。目录位置以C#的项目为例如下：

x86: Program Files\Microsoft Visual Studio 10.0\Common7\IDE\ProjectTemplates\CSharp\Web\1033
x64: Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\ProjectTemplates\CSharp\Web\1033

需要修改的文件为，下图中被标黄的：

将这三个文件复制出来，然后解压，做如下事情：

先把Scripts文件夹中的jQuery相关文件删除并更新为最新版的,包含jquery-1.4.2-vsdoc.js,jquery-1.4.2.js,jquery-1.4.2.min.js等
然后修改×××××.csproj文件中关于jquery1.4.1的引用改为1.4.2的引用
最后把××××××.vstemplate文件中的jquery-1.4.1替换为jquery-1.4.1
保存上述修改，并打包为zip文件
将新的同名zip文件覆盖回项目模板所在目录
再将打包前的文件覆盖到项目模板的缓存目录中（项目模板路径的ProjectTemplates改为ProjectTemplatesCache 便是）
完毕

如果您嫌麻烦，我这里有已经打包好的zip文件，您参考最后3步自己覆盖一下即可。(jquery.validate-vsdoc.js未找到最新的版本所以未更新，jquery.validate.js则已经是最新版了)

我近期讲过的vs2010有关的webcast列表整理

衣明志 — Mon, 10 May 2010 20:37:00 GMT

Visual Studio 2010于今年的4月12日正式发布，而且还是在中国北京进行的全球首发，盛况空前，且令人感动。

程序员“耀@爱情”系列情景剧也真实表现出了程序员们的爱情现状，值得深思，我们到底该如何平衡生活与工作呢？

ok，言归正传。我个人在4月份一整月基本都是在讲VS2010的有关课程，其中有线上的webcast和线下的面对面培训，还有一些小组讨论会之类的事情。忙得身体有点透支的感觉，不过当听到不少程序员在下载观看我的课程视频，心里还是很欣慰的，本月暂时只讲了一堂webcast，做一下休息和思想的沉淀，希望以后给大家带来更多的精彩内容。下面我整理一下近期讲过的与Visual Studio 2010有关的视频课程列表。

document.getElementsByClassName的较好实现

衣明志 — Sat, 15 Mar 2008 06:28:00 GMT

最近在项目中由于一个特殊的要求,需要使用类似于js的document.getElementsById的css class调用的实现。于是到网上搜索了一下，似乎并没有真正能较好达到目的且效率较理想的。于是乎，自己简单的写了一个，效率还凑合，而且支持多class名称的标签。代码如下：

function $(id){ return document.getElementById(id);
} Array.prototype.indexOf
= function(item,i){ i || (i = 0); var length = this.length; if< 0) i =  (i
length> + i; for<  (;
i length>; i++) if (this[i]
=== item) return i; return -1;

} document.getElementsByClassName = function(className,
parentElement){ var elems = ($(parentElement)||document.body).getElementsByTagName("*"); var result=[]; for (i=0;
j=elems[i]; i++){ if (j.className.split(/(\s+)/).indexOf(className)!=-1){
result.push(j); } } return result; }

使用时先将代码加在head部分或者写在独立的js文件然后在head里引用，然后在页面中适当的部分即可通过document.getElementsByClassName来获得指定class的标签数组。

支持百度的搜索引擎来源的关键字加亮

衣明志 — Tue, 10 Oct 2006 03:55:25 GMT

我们在上网使用搜索引擎的时候，经常会遇到类似这样的一个问题：从Google上搜索到了一个包含了“税收”的文章，但是打开对应的网站页面时发现这篇文章很长，很难确定税务在文章中的位置，即使使用浏览器的查找功能，也并不爽。那么如何改进信息类网站在此需求上的用户体验呢？一个国外的朋友做了件好事情：http://www.kryogenix.org/code/browser/searchhi/，他在这个页面上提供了一个js，可以很方便的实现我们的需求。但是这个脚本对baidu没有什么效果为什么呢？首先我们看看他的部分代码：

…… if (qsip[0]
== 'q'
|| qsip[0] == 'p') { // q= for Google, p= for Yahoo words = unescape(qsip[1].replace(/\+/g,'
')).split(/\s+/); for (w=0;whighlightWord(document.getElementsByTagName("body")[0],words[w]);
} } ……

上述代码获取来源地址中q或p的值，q对应的是google的搜索关键字，p是Yahoo的搜索关键字，而且这两个关键字是utf-8编码的，使用js自然可以很方便的处理，但是百度搜索的则有较大不同：搜索关键字的对应的地址参数是wd，且编码为GB2312。如何解决这个问题呢？我这里使用了js结合vbs的办法来解决该问题。

首先我们使用vbs写一个函数解决编码问题：

Function DeCodeAnsi(s) Dim i,
sTmp, sResult, sTmp1 sResult = "" For i=1 To Len(s) If Mid(s,i,1)="%" Then sTmp = "&H" & Mid(s,i+1,2) If isNumeric(sTmp) Then If CInt(sTmp)=0 Then i = i + 2 ElseIf CInt(sTmp)>0 And CInt(sTmp)<128 Then sResult = sResult
& Chr(sTmp)
i = i + 2 Else If Mid(s,i+3,1)="%" Then sTmp1 = "&H" & Mid(s,i+4,2) If isNumeric(sTmp1) Then sResult = sResult
& Chr(CInt(sTmp)*16*16 + CInt(sTmp1))
i = i + 5 End If Else sResult = sResult
& Chr(sTmp)
i = i + 2 End If End If Else sResult = sResult
& Mid(s,i,1) End If Else sResult = sResult
& Mid(s,i,1) End If Next DeCodeAnsi = sResult End Function

然后在js中调用这个vbs的函数：

if (qsip[0]
== 'wd') { //
wd= for baidu if(qsip[1]=='') continue;
execScript('wd = DeCodeAnsi("'+qsip[1]+'")','vbscript');
words = decodeURI(wd.replace(/\+/g,'
')).split(/\s+/); for (w=0;whighlightWord(document.getElementsByTagName("body")[0],words[w]);
} }

ok问题解决了。

使用的时候在网页中加上以下两行就好了：

searchhi.js (2.23 KB)
searchhi.vbs (.93 KB)

利用正则表达式限制网页表单里的文本框输入内容

衣明志 — Thu, 11 May 2006 01:57:11 GMT

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,''))"

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,''))"

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,''))"

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,''))"

改进版的渐变效果进度条

衣明志 — Wed, 22 Jun 2005 03:23:54 GMT

对原来的版本的渐变效果进度条做了改进，抛弃了长度达256的数组，并修改了样式表，实现了大幅度减少资源消耗。请看效果。

具体程序如下：

<html>
<head> <title>渐变效果进度条</title> <script language="javascript">
    var i;
    function go()
    {         bar_width = document.getElementById("bg").clientWidth;
        i = bar_width;
        setTimeout('start();',300);     }
    function start()
    {         if(i-->0)
        {             ps.style.width = i;
            bn.innerHTML = Math.floor((bar_width-i)/bar_width*100)+"%";
            setTimeout('start();',20);
        }     }     
</script> <style type="text/css">
#bg { filter:progid:DXImageTransform.Microsoft.Gradient(GradientType=1, StartColorStr=#FFFF00,
EndColorStr=#FF0000); width:300px; height:20px; border:1px solid black; z-index:0;
position:absolute; } #ps { float:right; background-color:#FFFF00; width:100%; } #bn
{ position:absolute; text-align:center; width:100%; height:100%; cursor:default; }
</style> </head> <body onload="go();">
<div id="bg"><div
id="ps"></div><span
id="bn">0%</span></div>
</body> </html>

身份验证常用正则表达式

衣明志 — Wed, 23 Mar 2005 09:04:12 GMT

中国电话号码验证
匹配形式如:0511-4405222 或者021-87888822 或者 021-44055520-555 或者 (0511)4405222
正则表达式 "((d{3,4})|d{3,4}-)?d{7,8}(-d{3})*"

中国邮政编码验证
匹配形式如:215421
正则表达式 "d{6}"

电子邮件验证
匹配形式如:justali@justdn.com
正则表达式 "w+([-+.]w+)*@w+([-.]w+)*.w+([-.]w+)*"

身份证验证
匹配形式如:15位或者18位身份证
正则表达式 "d{18}|d{15}"

常用数字验证
正则表达式
"d{n}" n为规定长度
"d{n,m}" n到m的长度范围

非法字符验证
匹配非法字符如:< > & / ' |
正则表达式 [^<>&/|'\]+

日期验证
匹配形式如:20030718,030718
范围:1900--2099
正则表达式((((19){1}|(20){1})d{2})|d{2})[01]{1}d{1}[0-3]{1}d{1}

关于JS中乘法的浮点错误解决方法

衣明志 — Wed, 23 Mar 2005 09:01:16 GMT

JS里做小数的乘法运算时会出现浮点错误，具体可以测试一下：

<script>
alert(11*22.9)
</script>

结果是251.89999999999998 而不是251.9

这个问题想必有很多人为之头痛。那么如何解决呢？在此给出解决办法。

1、

<script>
alert(11*(22.9*10)/10)；
</script>

解决问题的大概思路就是，先把因数放大为整数，最后再除以相应的倍数，这样就能得到正确的结果了。
2、

<script defer>
Number.prototype.rate=function(){
var oStr=this.toString();
if(oStr.indexOf(".")==-1)
return 1;
else
return Math.pow(10,parseInt(oStr.length-oStr.indexOf(".")-1));
}

function tran(){
args=tran.arguments;
var temp=1;
for(i=0;i<args.length;i++)
temp*=args[ i ]*args[ i ].rate();
for(i=0;i<args.length;i++)
temp/=args[ i ].rate();
return temp
}

alert(tran(11,22.9));

</script>

该解决办法是比较麻烦的办法，但是却能让你大概了解解决这个问题的实际过程。

实现列表CheckBox全选的Javascript

衣明志 — Wed, 23 Mar 2005 08:36:38 GMT

最近做公司内的一个小项目，需要做一个多选项目的删除功能，于是写以下JS脚本例子来实现，其实也是经常用到的比较基础的东西，高手就不用看了。

程序代码：

调用方法：
全选的名称定为allbox，onclick事件执行CA(this.form);
选择项的checbox的onclick事件执行CCA(this.form,this);
