VisualizaçõesRead Only property for input field
The thing that I'd like to happen is that when the value of the status field is Paid the input field fines should be read-only. How to achieve this?
This is my form:
This is my code:
<div class="form-group">
<label for="status" class="col-sm-3 control-label">Status</label>
<div class="col-sm-9">
<input type="text" class="form-control" id="status" value = "Paid" name="status" readonly>
</div>
</div>
<div class="form-group">
<label for="fines" class="col-sm-3 control-label">Fines</label>
<div class="col-sm-9">
<input type="text"
class="form-control" id="fines" name="fines" required>
</div>
</div>
Javascript line of code:
<script type = "text/javascript">
$(document).ready (function(){
$('input[type=text][name=status]').change(function() {
if (this.value == "Paid") {
$("#fines").prop("readonly",true);
}
else{
$("#fines").prop("readonly",false);
}
});
});
</script>

Seeing as you're status field is set to readonly on load, I'd imagine you want to trigger a change event instantly.
$(document).ready (function(){
// setup a variable for multi-use
var $statusField = $('input[type=text][name=status]');
// watch for changes to the statusField
$statusField.change(function() {
// simpler check for paid status
$('#fines').prop('readonly', this.value === 'Paid');
});
// trigger a change on ready
$statusField.change();
});
This way you have access to trigger the change programatically but also have the ability to watch the status field. I've also cleaned up your code a little bit!

try like this
if ($(this).val() == "Paid") {
$("#fines").attr("readonly",true);
}
else{
$("#fines").attr("readonly",false);
}
