I am having 2 dependent dropdowns. Second one is depend on first dropdown. I am using onchange event to get data in second dropdown with ajax call.
below is my 2 dropdowns and ajax call :
first select box:
<select name="cust_type" id="cust_type" class="cust_type"
onchange="getCustomersByType(this.value);" >
<?php echo $customer_type;?>
</select>
Second select box:
<select name="CompanyName[]" id="CompanyName" multiple class="customer_name" >
</select>
ajax call :
function getCustomersByType(value)
{
var getCust = $('#cust_type').val();
var customer_type = value;
$.ajax({
method: "GET",
dataType: 'json',
url:"include/ajax_files/bank_book/getdata.php?getCust="+getCust,
success:function(data)
{
$('#CompanyName').empty();
$.each(data, function(index, value)
{
$("#CompanyName").append('<option value="' + value.CUSTOMER_ID + '"' +
'>' + value.CUSTOMER_NAME+ '</option>');
$('#CompanyName').multiselect('rebuild');
});
}
});
};
my data is proper. I am able to change my second dropdown with change on first. But when i am using multiselect plugin with checkbox for multiselect second dropdown failed to change data.
Below is code for multiselect :
$(document).ready(function(){
$('#CompanyName').multiselect({
columns: 1,
placeholder: 'Select Com',
search: true,
selectGroup: true,
selectAll: true,
maxPlaceholderOpts: 0,
});
});
please help me with this to empty select onchange first dropdown and show data.
Use reload
method to display the new options after populating.
$('#CompanyName').multiSelect('reload');
