How to store value from one dropdown list to another dropdown list
Question
I have 2 dropdown list, where in the first dropdown list i have some data and if I select the data it has to be stored into the second dropdown list. Here is the code :-
This is the first dropdown list,
<select name="weekId" id="weekId" onchange="getSelected(value)">
<option value="Select">Select</option>
<option value="Weekly">Weekly</option>
<option value="Monthly">Monthly</option>
<option value="Both">Both</option>
</select>
This is the second list,
<select id="selectedWeek" name="selectedWeek" size="5" multiple="multiple">
If I select Weekly in the first dropdown, the value has to get stored in the second dropdown. How do I go about implementing this?
Thanks in advance!!

var weekId = document.getElementById('weekId')
, selectedWeek = document.getElementById('selectedWeek')
, option;
weekId.onchange = function() {
option = document.createElement('option');
option.value = this.value;
option.text = this.options[this.selectedIndex].text;
selectedWeek.appendChild(option);
weekId.removeChild(this.options[this.selectedIndex]);
};
see working fiddle here: http://jsfiddle.net/bKrFK/1/
the last line in the event-handler will remove the selected option from the weekId select-box (remove that line if not needed)

You can do this using Javascript:
function listbox_moveacross(sourceID, destID) {
var src = document.getElementById(sourceID);
var dest = document.getElementById(destID);
for(var count=0; count < src.options.length; count++) {
if(src.options[count].selected == true) {
var option = src.options[count];
var newOption = document.createElement("option");
newOption.value = option.value;
newOption.text = option.text;
newOption.selected = true;
try {
dest.add(newOption, null); //Standard
src.remove(count, null);
}catch(error) {
dest.add(newOption); // IE only
src.remove(count);
}
count--;
}
}
}
Pass this function with ids of your selectbox.

Try this..
<html>
<body>
<select name="weekId" id="weekId" onchange="document.getElementById('selectedWeek').value=this.value">
<option value="Select">Select</option>
<option value="Weekly">Weekly</option>
<option value="Monthly">Monthly</option>
<option value="Both">Both</option>
</select>
<select id="selectedWeek" name="selectedWeek" size="5" multiple="multiple">
<option value="Select">Select</option>
<option value="Weekly">Weekly</option>
<option value="Monthly">Monthly</option>
<option value="Both">Both</option>
</select>
</body>
</html>
Note : Second drop down has all value available in first select box.

First of all, when you call the javascript function in onChange event, replace getSelected(value) to getSelected(this.value) .
Now after that,
Your javascript function getSelected(value) should look like this
function getSelected(value)
{
document.getElementById("selectedWeek").innerHTML = '<option value="'+value+'">'+value+'</option>';
}

You could use the following, without any jQuery dependencies. I've added some comments to explain what is going on.
<script>
function handleSelection(weekDropDown) {
// Get selected value
var selection = weekDropDown.options[weekDropDown.selectedIndex].value;
var selectedWeekDropDown = document.getElementById("selectedWeek");
var opt;
if(selectedWeekDropDown.options[0]) {
// Replace
opt = selectedWeekDropDown.options[0];
} else {
// Add an option
opt = document.createElement("option");
}
if(!selectedWeekDropDown.options[0]) {
selectedWeekDropDown.options.add(opt);
}
// Set the option text and value
opt.text = selection;
opt.value = selection;
}
</script>
<select name="weekId" id="weekId" onchange="handleSelection(this)">
<option value="Select">Select</option>
<option value="Weekly">Weekly</option>
<option value="Monthly">Monthly</option>
<option value="Both">Both</option>
</select>
<select id="selectedWeek" name="selectedWeek" size="5" multiple="multiple">
