我有2個下拉選擇框，其中一個從列表中選擇您的國家，下一個下拉框應填充相應的州或地區。出於某種原因，'州/地區'字段將不會顯示任何基於從第一個下拉框中選擇的選項，即'國家/地區'字段。下拉選擇器不從數組中提取信息
我確實在一點工作，試圖恢復原來的代碼的方式，但我不能讓它繼續工作了。任何解決方案在那裏？
這裏是我的HTML代碼--------------->
<script type="text/javascript" src="../jquery.js"></script>
<script type="text/javascript">
jQuery(document).ready(function(){
// when any option from country list is selected
jQuery("select[name='Country']").change(function(){
// get the selected option value of country
var optionValue = jQuery("select[name='Country']").val();
/**
* pass country value through GET method as query string
* the 'status' parameter is only a dummy parameter (just to show how multiple parameters can be passed)
* if we get response from data.php, then only the cityAjax div is displayed
* otherwise the cityAjax div remains hidden
* 'beforeSend' is used to display loader image
* 'complete' is used to hide the loader image
*/
jQuery.ajax({
type: "GET",
url: "country-state-data.php",
data: {
Country: optionValue,
status: 1
},
beforeSend: function(){ jQuery("#ajaxLoader").show(); },
complete: function(){ jQuery("#ajaxLoader").hide(); },
success: function(response){
jQuery("#cityAjax").html(response);
jQuery("#cityAjax").show();
}
});
});
});
</script>
