When scripting a input validation code, there would be two timings

where the validation runs.

1. On change/blur(or others) event
2. On submit event

To make the validation work on both the above events,

the following is kept on mind..

Do not use $(this) in the validation code

Give the validation function a argument which is target input.

Example

$('input').change(stringValidation(this));

↑Not fired..

$('input').change(function(){return stringValidation(this);});

$('#submitButton').click(submit);

function submit(){

    if(!stringValidation($('input'))) {

      return false;

    }

}

function stringValidation(target) {

    var str = $(target).val();

    if(str===''){

      error handling;

      retrun false;

    }

}

Android SDK offline install

Due to the proxy or firewall settings, SDK installment through online was failed.

Hence, I tried to offline installment.

1. Open the repository xml file on https://dl-ssl.google.com/android/repository/repository-5.xml
2. Fetch the target SDK file specified in the "<sdk:url>" tag (e.g. <sdk:url>android-2.3.3_r02-linux.zip</sdk:url>: http://dl-ssl.google.com/android/repository/android-2.3.3_r02-linux.zip)
3. Put the fetched file to the directory "<sdk root>/temp"
4. Launch SDK Manager to install.

min-height handling for IE6

IE6 does not handle min-height property.

The following hack can handle this issue.

#target {

    min-height: 40px;

    height: auto !important;

    height: 40px;

}

jQuery | 10:47 |

jQuery live() does not work on IEs. Here is a good stuff to solve it!!

    $('div.show').show();

}).livequery('mouseout', function(){

    $('div.show').hide();

});

Installing ghostscript rpm package

I had the following error in installing ghostscrip rpm package on CentOS 5.7.

[root@xxxx src]# rpm -Uvh ghostscript-8.15.2-9.11.el5.i386.rpm ghostscript-fonts-5.50-13.1.1.noarch.rpm

エラー: 依存性の欠如:

urw-fonts >= 1.1 は ghostscript-8.15.2-9.11.el5.i386 に必要とされています

Then I tried to install urw-fonts, but another error came up..

[root@xxxx src]# rpm -Uvh urw-fonts-2.4-9.fc13.noarch.rpm

警告: urw-fonts-2.4-9.fc13.noarch.rpm: ヘッダ V4 DSA signature: NOKEY, key ID 42d68235

rpmlib(PayloadIsXz) <= 5.2-1 は urw-fonts-2.4-9.fc13.noarch に必要とされています

What was that? I did not find "rpmlib" something from anywhere.

I am totally at a loss to solve this..

Finally, I figured out how to get it done!

[root@xxxx src]# yum localinstall ghostscript*.rpm

jQuery button rollover

With regular expressions, it is quite easy to realize the button rollover function.

$(function(){

    $('li img').mouseover(function(){

        $(this).attr('src', $(this).attr('src').replace(/^(.+)(\.[a-z]+)$/, '$1_on.$2'));

    .mouseout(function(){

        $(this).attr('src', $(this).attr('src').replace(/^(.+)_on(\.[a-z]+)$/, '$1$2'));

    });

PHP install on CentOS5.7

In installing PHP on CentOS5.7, I encountered a configure error.

#configure: error: freetype.h not found.

Installing "freetype" seemed to be required, so I installed it.

yum install freetype freetype-devel

However, the same error occured.. mmm

I figured out that the freetype installed path is not recognized.

So I ended up the following configure line.

./configure \

• with-apxs2=/usr/local/apache2/bin/apxs \
• enable-mbstring \
• enable-mbregex \
• enable-zend-multibyte \
• with-gd \
• enable-gd-native-ttf \
• with-png-dir=/usr \
• with-zlib \
• with-jpeg-dir=/usr \
• with-mysql=/usr/local/mysql \
• with-freetype-dir=/usr/include/freetype2
