Advertising

Consider a small town where in everyone own atleast one apple tree. And almost all apples are found similar in every ways. Since it is being owned by everyone no one made a big fuss about their apple's features like appearance, taste, etc.,

But to every one's surprise later it was found that a single tree alone yielded fruits which were delicious to the core. But this was unknown to people for a long time due to lack of awareness in advertising.

Often, In Indian conservative families, kids are always told not to advertise things. And are advised to have everything low. So, I feel that indirectly people inculcate the habit of considering the act of advertising(i mean breaking out and telling the people around you that u have something unique) is something which we are not supposed to do.

At some point of time, It ends up like even though we have some talents it gets deteriorated and destroyed without others realizing it which is equivalent to not having it.

So, I think we should change. Its the right time we change. I will have to develop the interest in notifying others about my positive skills.....

Navigation of elements for listboxes in javascript

I happened to implement a simple navigation functionality between two listboxes in my web page. Controlling navigations is best done with the help of javascript. I am posting this with the assumption that, this is one among the commonly used functionality.

Lets step into the intrinsic details now. Consider the following image,
The idea is to control the navigations between source and target listboxes and ordering of elements in the target listbox. We can achieve this with simple javascript functions,

function addItem(sourceListBox,targetListBox,delimiter)
{
var source=document.getElementById(sourceListBox);
var destination=document.getElementById(targetListBox);
for(i=0; i<source.options.length;i++)
{
if(source.options[i].selected==true)
{
var o = document.createElement("option");
destination.options.add(o);
o.text = source.options[i].text;
o.value = source.options[i].value;
}
}
}

function deleteItem(templateList)
{
var listbox=document.getElementById(templateList);
var t=0;
for(i=0; i<listbox.options.length;i++)
{
if(listbox.options[i].selected==true)
{
listbox.remove(i);
}
}
}
function moveUp(templateList)
{
var listbox=document.getElementById(templateList);
vart=0;
for(i=0; i<listbox.options.length;i++)
{
if(listbox.options[i].selected==true)
{
previousItemText = listbox.options[i-1].text;
previousItemValue = listbox.options[i-1].value;
listbox.options[i-1].text=listbox.options[i].text;
listbox.options[i-1].value=listbox.options[i].value;
listbox.options[i].text=previousItemText;
listbox.options[i].value=previousItemValue;
listbox.options[i].selected=true;
t=i;
}
}
listbox.options[t-1].selected=true;
}

function moveDown(templateList)
{
var listbox=document.getElementById(templateList);
var t=0;
for(i=0; i<listbox.options.length;i++)
{
if(listbox.options[i].selected==true)
{
nextItemText = listbox.options[i+1].text;
nextItemValue = listbox.options[i+1].value;
listbox.options[i+1].text=listbox.options[i].text;
listbox.options[i+1].value=listbox.options[i].value;
listbox.options[i].text=nextItemText;
listbox.options[i].value=nextItemValue;
t=i;
}
}
listbox.options[t+1].selected=true;
}
