I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.

Sometimes when setting a variable, you may want to do something else with the given value other than instantly place it in the class's variable: for instance, you may want to validate it or update another value that is related.
ReplyDeleteBasically, it lets the class which owns that variable control what can be done to it, and the specific series of events that occur when it is altered.
e.g. we can verify that user setting age of person is not more than 150 or less than zero.
public class Person{
private int age;
public int getAge(){
return this.age;
}
public void setAge(int age){
if(age<150 && age>0){
this.age=age;
}
}
}
It also needs to be mentioned that it is not always better to use "set" methods. Blind compliance with patterns may lead to overcomplicated code. If class acts as just simple (really simple) data container, then public access is often acceptable. In example, look at java.awt.Rectangle or at java.awt.Point classes.
ReplyDeleteIt all has to do with object orientation and how strict you are in that doctrine. If you strictly follow all the guidelines, it is bad to directly use methods and identifiers from one class, by the other. Technically there is no objection.
ReplyDeleteThis discussion is the same as the static - no static discussion. The (self proclaimed) guru, found that sacrilege, but you put your computer no obstacle in the way, if you put your whole program is static.
