Create a dynamic SELECT drop-down list (combo-box) in JavaScript

In real-time web applications, sometimes we are required to create a dynamic select drop-down list (combo box) which means the options will be loaded at run time for that combo box. This article shows you to create a drop-down list dynamically using JavaScript, HTML, and JSON. Here we will see multiple examples to dynamically populate select options in JavaScript.

Overview

To create a dynamic drop-down combo or drop-down list, let’s assume we have a dynamic JSON array that contains the country list data (code, name) as follows:

[{
	"code":"AU",
	"name":"Australia"
},{
	"code":"FR",
	"name":"France"
},{
	"code":"IN",
	"name":"India"
},{
	"code":"JP",
	"name":"Japan"
},{
	"code":"CH",
	"name":"Switzerland"
},{
	"code":"GB",
	"name":"United Kingdom"
},{
	"code":"US",
	"name":"United States"
}]

Create a dynamic drop-down list on button click in Javascript.

To create a drop-down list dynamically on button click, we will see here multiple examples based on the country data formats. For all the examples we will have the common HTML code only Javascript code will change.

HTML CODE

<button onclick="dynamicDropdownList()">Create Dynamic Dropdown List</button>	
<br><br>
<!-- container to load dynamic dropdown list -->
<div id="dropdown-container"></div>

Example-1.

Let’s assume we have country data in the form of a string array as follows:

var countries = ["Australia","France","India","Japan","United States"];

Let’s see the javascript code for this as follows:

<script>
//country data in string array format
var countries = ["Australia","France","India","Japan","United States"];

//This method calls on button click
function dynamicDropdownList(){

	var dropdown = document.createElement("select");
	for(var i=0;i<countries.length;i++){		
		var opt = document.createElement("option"); 
		opt.text = countries[i];
		opt.value = countries[i];
		dropdown.options.add(opt);		
	}
	
	//Load the dynamically created dropdown in container
	var container=document.getElementById("dropdown-container");
	container.appendChild(dropdown);
}

</script>

Example-2.

Let's assume we have country data in the form of a JSON array as follows:

var countries = [{
	"code":"AU",
	"name":"Australia"
},{
	"code":"FR",
	"name":"France"
},{
	"code":"IN",
	"name":"India"
},{
	"code":"JP",
	"name":"Japan"
},{
	"code":"CH",
	"name":"Switzerland"
},{
	"code":"GB",
	"name":"United Kingdom"
},{
	"code":"US",
	"name":"United States"
}];

Then we can write the javascript code for this as follows:

<script>
//country data in json array format
var countries = [{
	"code":"AU",
	"name":"Australia"
},{
	"code":"FR",
	"name":"France"
},{
	"code":"IN",
	"name":"India"
},{
	"code":"JP",
	"name":"Japan"
},{
	"code":"CH",
	"name":"Switzerland"
},{
	"code":"GB",
	"name":"United Kingdom"
},{
	"code":"US",
	"name":"United States"
}];

//This method calls on button click
function dynamicDropdownList(){

	var dropdown = document.createElement("select");
	for(var i=0;i<countries.length;i++){		
		var opt = document.createElement("option"); 
		opt.text = countries[i].name;
		opt.value = countries[i].code;
		dropdown.options.add(opt);		
	}
	
	//Load the dynamically created dropdown in container
	var container=document.getElementById("dropdown-container");
	container.appendChild(dropdown);
}

Example-3.

In this example, we will take the above JSON array only, but here we will write a different javascript logic to create a dynamic drop-down list.

<script>
//country data in json array format
var countries = [{
	"code":"AU",
	"name":"Australia"
},{
	"code":"FR",
	"name":"France"
},{
	"code":"IN",
	"name":"India"
},{
	"code":"JP",
	"name":"Japan"
},{
	"code":"CH",
	"name":"Switzerland"
},{
	"code":"GB",
	"name":"United Kingdom"
},{
	"code":"US",
	"name":"United States"
}];

//This method calls on button click
function dynamicDropdownList(){
	var dropdownHTML = '<select>';
	for(var i=0;i<countries.length;i++){
		var name = countries[i].name;
		var value = countries[i].code;
		dropdownHTML+='<option value="'+value+'">'+name+'</option>';
	}
	dropdownHTML+='</select>';		
	//Load the dynamically created dropdown in container
	var container=document.getElementById("dropdown-container");
	container.innerHTML=dropdownHTML;
}
