I am trying to do the following:
I have drop down menu with four options in it. When I choose Shipped a text box should enabled. So I tried the following:
<div class="col-md-3">
<select class="form-control" id="ostatus" name= "ostatus">
<option value="Uploaded" <?php if ($dispatch_status == "Uploaded") echo "selected='selected'";?> >Uploaded</option>
<option value="Processing" <?php if ($dispatch_status == "Processing") echo "selected='selected'";?> >Processing</option>
<option value="Dispatched" <?php if ($dispatch_status == "Dispatched") echo "selected='selected'";?> >Dispatched</option>
<option value="Shipped" <?php if ($dispatch_status == "Shipped") echo "selected='selected'";?> >Shipped</option>
</select>
</div>
</div>
<input type="text" class="form-control" name="shipping_notes" disabled="true" id="shipping_notes" aria-describedby="" placeholder="Enter Shipping details">
Java script:
<head>
<script type="text/javascript">
document.getElementById('ostatus').addEventListener('change', function()
{
console.log(this.value);
if (this.value == 'Shipped') {
document.getElementById('shipping_notes').disabled = false;
} else {
document.getElementById('shipping_notes').disabled = true;
}
});
</script>
</head>
Doesn't seem to trigger? I don't see log on console too. What could be wrong here?
Update:
I have pasted the html code here:

Since you've now shared your other code I think I know what you want. You have multiple modals, each with a select
list and shipping_notes
textbox which should be enabled when the selection is Shipped
for that particular modal. I've modified your HTML to get this working.
I've updated your HTML a bit. You have multiple elements with the same ID. HTML IDs should be unique. If you want to target multiple elements it's safer to use class
(or data-
) attributes. I've added class="order-status"
to each select
and class="shipping_notes_txt"
to each textbox. I've used element.querySelector()
and document.querySelectorAll()
to select DOM elements.
The snippet below mimics two modals. When the select
is updated, it only enables/disabled the textbox within the same form
element.
// wait for the DOM to load
document.addEventListener('DOMContentLoaded', function() {
// get all select elements with class=order-status
var selects = document.querySelectorAll('.order-status');
// iterate over all select elements
for (var i = 0; i < selects.length; i++) {
// current element
var element = selects[i];
// add event listener to element
element.addEventListener('change', function()
{
console.log(this.value);
// get the form closest to this element
var form = this.closest('form');
// find the shipping notes textbox inside form and disable/enable
if (this.value == 'Shipped') {
form.querySelector('.shipping_notes_txt').disabled = false;
} else {
form.querySelector('.shipping_notes_txt').disabled = true;
}
});
// default value if status == Shipped: enable textbox
if (element.value == "Shipped")
{
var form = element.closest('form');
form.querySelector('.shipping_notes_txt').disabled = false;
}
}
});
.modal1 {
display:inline-block;
vertical-align:top;
padding: .5em;
padding-bottom:5em;
border: 1px solid black;
}
<div class="modal1">
<h3>First Modal</h3>
<div id="edit1" class="modal fade" role="dialog">

assuming everything on the server side this works HTML comes first
<div class="col-md-3"> <select class="form-control" id="ostatus" name= "ostatus">
<option value="Uploaded" selected="selected" >Uploaded</option>
<option value="Processing" >Processing</option>
<option value="Dispatched" >Dispatched</option>
<option value="Shipped" >Shipped</option>
</select>
</div>
</div>
<input type="text" class="form-control" name="shipping_notes" disabled="true" id="shipping_notes" aria-describedby="" placeholder="Enter Shipping details">
document.getElementById('ostatus').addEventListener('change', function()
{
console.log(this.value);
if (this.value == 'Shipped') {
document.getElementById('shipping_notes').disabled = false;
} else {
document.getElementById('shipping_notes').disabled = true;
}
});

Add onchange to your <select>
<select class="form-control" id="ostatus" name= "ostatus" onchange = "statuschange()">
And change the JavaScript to :
<script type="text/javascript">
function statuschange(){
var drpDownValue = document.getElementById('ostatus').value;
if (drpDownValue == 'Shipped')
{
document.getElementById('shipping_notes').disabled = false;
}
else
{
document.getElementById('shipping_notes').disabled = true;
}
}
</script>
