As the question says, how do I add a new option to a DropDownList using jQuery?
Thanks
This question is related to
jquery
user-interface
drop-down-menu
Pease note @Phrogz's solution doesn't work in IE 8 while @nickf's works in all major browsers. Another approach is:
$.each(myOptions, function(val, text) {
$("#mySelect").append($("<option/>").attr("value", val).text(text));
});
I needed to add as many options to dropdowns as there were dropdowns on my page. So I used it in this way:
function myAppender(obj, value, text){
obj.append($('<option></option>').val(value).html(text));
}
$(document).ready(function() {
var counter = 0;
var builder = 0;
// Get the number of dropdowns
$('[id*="ddlPosition_"]').each(function() {
counter++;
});
// Add the options for each dropdown
$('[id*="ddlPosition_"]').each(function() {
var myId = this.id.split('_')[1];
// Add each option in a loop for the specific dropdown we are on
for (var i=0; i<counter; i++) {
myAppender($('[id*="ddlPosition_'+myId+'"]'), i, i+1);
}
$('[id*="ddlPosition_'+myId+'"]').val(builder);
builder++;
});
});
This dynamically set up dropdowns with values like 1 to n, and automatically selected the value for the order that dropdown was in (i.e. 2nd dropdown got "2" in the box, etc.).
It was ridiculous that I could not use this
or this.Object
or $.obj
or anything like that in my 2nd .each()
, though --- I actually had to get the specific ID of that object and then grab and pass that whole object to my function before it would append. Fortunately the ID of my dropdown was separated by a "_" and I could grab it. I don't feel I should have had to, but it kept giving me jQuery exceptions otherwise. Something others struggling with what I was might enjoy knowing.
And also, use .prepend() to add the option to the start of the options list. http://api.jquery.com/prepend/
Lets think your response is "successData". This contains a list which you need to add as options in a dropdown menu.
success: function (successData) {
var sizeOfData = successData.length;
if (sizeOfData == 0) {
// NO DATA, throw an alert ...
alert ("No Data Found");
} else {
$.each(successData, function(val, text) {
mySelect.append(
$('<option></option>').val(val).html(text)
);
});
} }
This would work for you ....
You may want to clear your DropDown first $('#DropDownQuality').empty();
I had my controller in MVC return a select list with only one item.
$('#DropDownQuality').append(
$('<option></option>').val(data[0].Value).html(data[0].Text));
With the plugin: jQuery Selection Box. You can do this:
var myOptions = {
"Value 1" : "Text 1",
"Value 2" : "Text 2",
"Value 3" : "Text 3"
}
$("#myselect2").addOption(myOptions, false);
try this Function:
function addtoselect(param,value){
$('#mySelectBox').append('<option value='+value+'>'+param+'</option>');
}
using jquery you can use
this.$('select#myid').append('<option>newvalue</option>');
where "myid" is the id of the dropdown list and newvalue is the text that you want to insert..
U can use direct
$"(.ddlClassName").Html("<option selected=\"selected\" value=\"1\">1</option><option value=\"2\">2</option>")
-> Here u can use direct string

Add item to list in the begining
$("#ddlList").prepend('<option selected="selected" value="0"> Select </option>');
Add item to list in the end
$('<option value="6">Java Script</option>').appendTo("#ddlList");

With no plug-ins, this can be easier without using as much jQuery, instead going slightly more old-school:
var myOptions = {
val1 : 'text1',
val2 : 'text2'
};
$.each(myOptions, function(val, text) {
$('#mySelect').append( new Option(text,val) );
});
If you want to specify whether or not the option a) is the default selected value, and b) should be selected now, you can pass in two more parameters:
var defaultSelected = false;
var nowSelected = true;
$('#mySelect').append( new Option(text,val,defaultSelected,nowSelected) );
Add item to list in the begining
$("#ddlList").prepend('<option selected="selected" value="0"> Select </option>');
Add item to list in the end
$('<option value="6">Java Script</option>').appendTo("#ddlList");
