我在HTML中准备了一个考勤记录模板。我在给定的HTML页面中有一个HTML表格和一个提交按钮。点击提交按钮,我想将数据保存在HTML表格中。但我不能

答案 0 :(得分:2)
您不应该像在HTML中那样手动生成表单。我可以看到你已经看过django表格了。我可以提出以下建议:
<form name="demo_form.asp" method="post">
{% csrf_token %}
{{ form.as_p }}
<button type="submit" value="continue">Submit</button>
</form>
还有很多其他form rendering options。此方法还将确保在表单验证失败时自动显示正确的消息。
另请注意,我已将GET更改为POST。使用帖子表格总是更好。如果您没有安装csrf中间件,我已添加{%csrf_token%}删除它。
答案 1 :(得分:0)
在模板中form
在定义任何input
元素之前关闭,因此表单不包含作为表格一部分输入的任何数据。
您可以通过将</form>
结束标记移动到表格结尾后的某个位置来修复它。
此外,<input>
标记没有name
属性,因此输入元素中输入的值都不能在HTTP请求中传递。例如,第一个表行可以写为:
<tr>
<td>1</td>
<td>Abijith</td>
<td>
<input type="number" id="aNumber" name="aNumber">
<button onclick="aFunction()"><font color="green">Present</button>
<button onclick="abFunction()"><font color="red">Absent</button>
<input type="number" id="abNumber" name="abNumber">
</td>
</tr>
请注意,name
属性已添加到输入标记中。
可能还有其他问题,但这是一个让我感到高兴的问题。

另一个问题是视图需要在POST请求中发送数据,但是表单正在使用GET。将HTML表单更改为使用method="post"
。
