There are sevral checkbox with name 'chk'.
and you want to know how many chk boxes there.
if you're confuse id and name, you'll get different result.
1. ID
$("#chk_can").length
returns 1
2. NAME
$("input[name='chk_can']").length
returns 3

There're 2 radio buttons
I'd like to choose radio button and check it with jQuery accroding to DB value.
what if DB value is '10'.
>> $("input[name=FS_type]").filter('[value='10']').attr('checked',true);
It doesn't work. Any idea?

jQuery - exist element?
Jquery returns its length even though it hasn't created yet.
$("#id").length = 0 means there's no element for '#id'
if($("#id").length > 0 ) {
// to do something...
}
$("#id").length = 0 means there's no element for '#id'
if($("#id").length > 0 ) {
// to do something...
}
how to exit from each loop - jQuery
"If you wish to break the each() loop at a particular iteration you can do so by making your function return false. Returning non-false is the same as a
$("#element-name").each(function(i){
if(this.val() == ''){
alert("null");
return false;
}
});
if jQuery is surrounded by another function, how can you do it?
i.e
function test() {
$("#element-name").each(function(i){
if(this.val() == ''){
alert("null");
return false;
}
});
// do something more
}
probably you can't avoid below logic.
Any idea to exit at once from whole function?
continue
statement in a for loop, it will skip "$("#element-name").each(function(i){
if(this.val() == ''){
alert("null");
return false;
}
});

[Python] 파이썬 예제2
역시 환율을 가져오는 프로그램이다
첫번째 버전은 그냥 스트링을 짤랐기 때문에 아주 허접한 버전이었지만
이번 버전에서는 금액으로 값을 리턴하고자 한다 즉 원하는 결과값은
THB : 36.60
현재 문제점을 정리해 보면
1. HTML 로 되어있다
2. 정확하게 어떤 값을 긁어서 가져와야 하는지 명확하지 않다
3. minidom 이 HTML도 DOM 처럼 다룰 수 있는지 모르겠다
[Python] 파이썬 예제1
# -*- coding: utf-8 -*-
# 네이버 환율에 접속해서 환율 정보를 가져오는 프로그램
import urllib2
f = urllib2.urlopen('http://bank.naver.com/index/exchange.nhn')
#print f.read(2000)
str1 = f.read()
# 3번째 THB를 찾아라
s_point = str1.find('THB')
print str1[s_point-30:s_point+10]
