I am a newbie learning web development. I am trying to create a simple form with two dropdowns. Based on first drop down second dropn down should be visible.
But it is not working :
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
</head>
<body>
<div class="container">
<div class="box">
<form>
<div class="ccms_form_element cfdiv_custom">
<div class="col-md-4">
<label for="inputType">Input Type</label></div>
<div class="col-md-8" style="font-size:16pt;">
<select id="inputType" required name="inputType" style="width:500px" onChange="ChangeDropdowns();">
<option value="">Select Type : Type Of You Want to Process</option>
<option value="text">Text </option>
<option value="genome">Numbers</option>
<option value="chacha">Special Characters</option>
</select>
</div>
</div>
</div>
<div class="style-sub-1" id="dataType" style="display: none;" >
<div class="col-md-4">
<label for="inputType">Data Type</label></div>
<div class="col-md-8" style="font-size:16pt;">
<select id="data" required name="data" style="width:500px">
<option value="">Select Data Source : Where is your Data?</option>
<option value="text">Data is already in Server</option>
<option value="genome">Need to Upload the File</option>
</select>
</div>
</div>
<div class="row">
<script>
function ChangeDropdowns() {
$(".style-sub-1").show();
}
</script>
</body>
</html>
Can someone tell me what I am doing wrong here ?
Use the following, using JQuery to detect the change in first select - and include JQuery as Scott said
$( document ).ready(function() {
$("#inputType").on('change', function (){
$(".style-sub-1").show();
});
});
It looks like you are trying to use jquery (the $ in your javascript code). However, you haven't specified the jquery script in your html.
Try adding this
<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.3.js"></script>
