Javascript change dropdown or select option value which is index

I google for "javascript change select value" and turn out not really help full
The keyword for select is more like dropdown
while the value is index
So it must be "javascriptchange dropdown index"

The purpsoe of this post is a javascript is to change the selection inside the dropdown into something you want.


Hello
World


Just like the dropdown above. The default value is seet to the first option which is "Hello"
When I click a certain script with value "World", the script will change the dropdown into to "World". This is what I want. Below is the code

function changeDropDown( dropdownidname, dropdownvalue)
{
var testingga = window.opener.document.EditView.elements[dropdownidname];
//In most case it will be document.getElementById(dropdownidname); I think

for (var i=0; i < testingga.length; i++)
{
if (testingga[i].value == dropdownvalue)
{
testingga[i].selected = true;
}
}
}

PHP Display array pre print_r into list button ul li

Display array in list (collapsable)

Display array in ul li

Display array in pre

Usually in programming, when you debugging an array you will be using the pre and print_r
This is all right when the data is small. But if the array size is very large things will be hard which is happen to me lately.

So I create a function that display the array on the list. Plus this list is collapsible and it is a very simple code. Only 2 function needed

function thejavascriptrewrite()

{

echo "<script type='text/javascript'>";

echo "

function switchme( \$theId)

{

\$theElement = document.getElementById(\$theId);

if( \$theElement.style.display == 'none'){

\$theElement.style.display = '';

}

else{

\$theElement.style.display = 'none';

}

}

";

echo "</script>";

}

function arraytolist( $data, $iteration = 0, $fortheUL = null)

{

$idName = "someCounterId";

echo "<ul $fortheUL>";

foreach( $data as $key => $value)

{

if( !is_array($value)){

echo "<li>";

echo "[$key]=".$value;

echo "</li>";

}

else{

$iteration++;

$totalArray = count( $value);

echo "<li>"."<a onclick=\"switchme('$idName".$iteration."')\">$key ($totalArray)</a>";

$forNextUL = "id='$idName".$iteration."' style='display: none;'";

$iteration = arraytolist($value, $iteration, $forNextUL);

echo "</li>";

}

}

echo "</ul>";

return $iteration;

}

How to use?

paste this code

$data = array( 'abc', 'def', 'ghi');

thejavascriptrewrite();

arraytolist($data);

Display and Disable Super hidden file

Yuu all know most of virus is hidden and the most typical way for them to infect you PC was through portable media like pen drive or portable harddisk.
I got alot of this case when I put my portable HDD to my friend. Luckyly I got antivirus to detect them but not to remove them.

The problem is the virus file is hidden and its not just typical hidden. Its a 'Super hidden file' where your 'Tool > Folder option > Show hidden file and folder' wont help at all.
So to encounter this you must use the command line aka cmd

So, type 'cmd' at run.

Navigate the 'cmd' into the portable media. In my case is typing 'I:' which direct me into I:\>



After that type 'dir /ah' and I see the virus! which is rfg.exe and his buddy autorun.inf.



The problem is I can see it in cmd but cant see in normal view.
So I disable their 'super hidden' using cmd by typing
'attrib -s -h -r rfg.exe' and 'attrib -s -h -r autorun.inf'

After typing these 2 things and It shows. So I delete them.

Just for friendly reminder. Never double click portable media. Right click and 'Explore' is the easy safest way.

Thats it, hope its usefull

*note

I just encounter another virus in my PenDrive but this method does not work

So this tutorial is not going to 100% solve your problem
