VisualizaçõesSelect option change values based on first select option , Jquery
A brief explanation on the code below:
- 2 select options , with 1 button
- the (#myButton) triggers the alert
- The (#op2) 2nd select option value, depends on the first selection (#op1)
On JSFiddle my code work but whenever I transfer it on my website I get the Uncaught : TypeError. Please provide your suggestions to resolve TypeError.
$('#myButton').on('click', function() {
var op1 = document.getElementById("op1").value;
alert(op1);
var op2 = document.getElementById("op2").value;
alert(op2);
if (op1 =='a'){
$("#op2").html("<select id='op2'><option value='800'>800</option><option value='3000'>3000</option></select>");
}
})<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select id="op1" >
<option value="a">a</option>
<option value="b">b</option>
<option value="all">all</option>
</select>
<select id="op2">
<option value="1">1</option>
<option value="11">11</option>
</select>
<input type="submit" value="button" id="myButton" class="buttonClass" />

Your script needs to be placed in the head tag <head></head> and must be loaded before your script.
<!DOCTYPE html>
<html>
<head>
<title>Title of the document</title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="yourLocalPath.js"></script>
</head>
<body>
<select id="op1" >
<option value="a">a</option>
<option value="b">b</option>
<option value="all">all</option>
</select>
<select id="op2">
<option value="1">1</option>
<option value="11">11</option>
</select>
<input type="submit" value="button" id="myButton" class="buttonClass" />
</body>
</html>
