I've tried different way, proposed in other discussions, to check if the value of an text input change. But I've not found a solution that works in my case. Can you help me? I've a form this main page:
<?php
$pdo = new PDO("mysql:host=localhost;dbname=db_nvh;charset=utf8", "root", "root");
?>

});
});
</script>
<script type="text/javascript">
$(function() { // This code will be executed when DOM is ready
$('#id_car').change(function() { // When the value for the id_car element change, this will be triggered
var $self = $(this); // We create an jQuery object with the select inside
$.post("getCarData.php", { id_car : $self.val()}, function(json) {
if (json && json.status) {
$('#brand').val(json.brand);
$('#model').val(json.model);
$('#gear_box_type').val(json.gear_box_type);
if(json.sunroof === 'yes'){
// var var_name = $("input[name='sunroof2']:checked").val();
$('#sunroof2').attr('checked', 'checked');
} else { // var var_name = $("input[name='sunroof1']:checked").val();
$('#sunroof1').attr('checked', 'checked'); } ;
}
var element = document.getElementById('gear_box_type');
element.value = json.gear_box_type;
})
});

When the user select a value from the fist text input the others text input, radio button and dropdown menu have to be setted according to the value loaded from mysql database. If i use a simple select input to select a car added to the database the javascript works fine and it check when the selected value change. If i use combogrid with a simple text input it doesn't works fine and javascript doesn't check any changes and data are non loaded from database with ajax. How can i solve?
UPDATE 1
I've tried in this way:
$(function() {
onSelect:function(record){
$('#id_car').combogrid({
var $self = $(this); // We create an jQuery object with the select inside
$.post("getCarData.php", { id_car : $self.val()}, function(json) {
if (json && json.status) {
$('#brand').val(json.brand);
$('#model').val(json.model);
$('#gear_box_type').val(json.gear_box_type);
if(json.sunroof === 'yes'){
// var var_name = $("input[name='sunroof2']:checked").val();
$('#sunroof2').attr('checked', 'checked');
} else { // var var_name = $("input[name='sunroof1']:checked").val();
$('#sunroof1').attr('checked', 'checked'); } ;
}
var element = document.getElementById('gear_box_type');
element.value = json.gear_box_type;
})
});
}
}
})
But it doesn't work. I don't know if there is something wrong.
