我有以下表单。JavaScript之所以有效，是因为我已经将其用于其他表单。基本上禁用"添加地址"（继续）按钮，直到完成所有字段。但我添加了一个地址功能，用户只输入他们的门牌号和街道，然后自动填写其他两个字段（城镇和邮政编码）（该功能的JavaScript不会显示为不需要）。因此，由于这两个字段是自动填充的，用户不输入它们，因此原始JavaScript不起作用，"添加地址"（Continue）按钮保持禁用状态。有什么想法吗？
编辑：
我已经设法解决了这个问题。我重新排列了表格，把"国家名单、门牌号、城镇和邮政编码"放在表格的开头而不是末尾。它现在起作用了。但不确定为什么会有不同。

设置输入字段的值后，触发字段的keyup事件。
function setValues(){
var my_field = $('#myfield');
my_field.val('Alice');
my_field.trigger('keyup');
}
在你的情况下，我认为这样做就足够了：
$('#firstname, #surname, #addresslist, #autocomplete').bind('keyup', function() {
if(allFilled()) $('#continue').removeAttr('disabled');
});
$('#firstname, #surname, #addresslist, #autocomplete').keyup();
