Question

我有以下表格。 JavaScript之所以有效，是因为我已经将它用于其他形式。基本上禁用“添加地址”（继续）按钮，直到完成所有字段。但是我添加了一个地址功能，用户只在其门牌号和街道中键入，然后自动填写其他两个字段（城镇和邮政编码）（此功能的JavaScript未显示为不需要）。因此，因为这两个字段是自动填充的，并且用户没有输入它们，所以原始JavaScript不起作用，并且“添加地址”（继续）按钮保持禁用状态。有什么想法吗？

编辑：

我设法解决了这个问题。我已经重新安排了表单，将“国家/地区列表，门牌号码，城镇和邮政编码”放在表单的开头而不是结尾处。它现在有效。不知道为什么它会有所作为。

设置输入字段的值后，触发该字段的keyup事件。

function setValues(){
    var my_field = $('#myfield');
    my_field.val('Alice');
    my_field.trigger('keyup');
}

在你的情况下，我认为这样就足够了：

$('#firstname, #surname, #addresslist, #autocomplete').bind('keyup', function() {
            if(allFilled()) $('#continue').removeAttr('disabled');
        });

$('#firstname, #surname, #addresslist, #autocomplete').keyup();

JavaScript表单错误？
