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.
For Demo: Listbox move left-right options JavaScript
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">
