根据选中的复选框更新值

标签： php html

我正在尝试根据表单上的选择更新文本框中的值。当用户选中一个选项框时，我试图让总成本增加一定的数量。其他所有工作都在表单上，​​如果我手动更改成本值，它将正确地发布到数据库。这可能与我的方法有关，还是我需要采用不同的技术？

<HEAD>
<script>
function tally()
{
    Cost = 60;

    if (Document.edituser.survivor10.checked ) { Cost = Cost + 10;    }
    if (document.edituser.high5.checked ) { Cost = Cost + 10;    }
    if (document.edituser.margin.checked == true ) { Cost = Cost + 10;  }
    if (document.edituser.survivor20.checked == true ) { Cost = Cost + 20;  }
    if (document.edituser.confidence.checked == true ) { Cost = Cost + 10;  }
    if (document.edituser.loser.checked == true ) { Cost = Cost + 10;  }
    if (document.edituser.vegas.checked == true ) { Cost = Cost + 10;  }                
    document.edituser.cost.value =  Cost;

}

JavaScript区分大小写，因此Document和document是两回事。在您的情况下，您想使用document。因此，您应该更改所有条件内的条件，以使用document。

顺便说一下。永远不要相信用户！您可以在客户端进行计算，作为用户的指标，但您应该在服务器端再次执行此操作，否则每个人都可以将成本发布为类似 - 甚至是负数。
