如何删除 Jquery PHP 回显错误？

Question

我有一个 Web 表单代码，其中有两个字段名称、日期和标题。我在我的代码中使用 jquery 来显示当前日期和日历，当我在日期字段中更改日期时，它会自动在标题字段中更改。我在标题字段中有一些硬代码。现在我的问题是，当我更改日期时，硬代码不会显示，我的 php 代码是另一个文件，无法获取标题的值，也无法在数据库 mysql 中存储任何值。

这是我的代码。

日期不变的输出

日期更改后的输出

Answer 1

通过 $("#dt_title").html(dateText); 你删除了跨度内的输入字段，只写纯日期文本。您应该设置标题输入的值而不是跨度 html。固定码：

onSelect: function(dateText, inst) {
            $("#dt_title input[type='text']").val(dateText);
        }

要在输入中保留标题并仅更改日期，您需要在输入的附加属性中保存标题：

<input name="title" type="text" value=" MB | Falcons | <?php echo date("d-M-y");?>" data-title="MB | Falcons | " style="width:200px"/>

然后在 jQuery 中通过添加属性中的标题更改输入值：

$("#dt_title input[type='text']").val($("#dt_title input[type='text']").attr('data-title')+dateText);
