我现在遇到了正在编辑的记录验证的问题。
编辑表单（和添加表单）有一个名为“email”的字段。该字段在数据库中应该是唯一的，因此我使用ajax来验证它，通过此函数：
function check_email(value, colname) {
$.ajax({
url: '@Url.Action("CheckEmail")',
data: { email: value },
type: 'POST',
async: false,
datatype: 'text',
success: function (data) {
if (!data) result = [true, ""];
else result = [false, colname + ": ya existe en el sistema"];
}
})
return result;
}
这样可行，但问题是我在编辑记录时。当然，在这种情况下存在电子邮件，因此不允许我保存记录。
算法可能是：只有在id为＆gt;时才应验证。 0和输入的电子邮件与现有值不同。换句话说，如果用户正在更改电子邮件，则必须进行验证。
我花了很多时间试图弄清楚如何知道editform是用于添加还是用于编辑，甚至更多，我试图找到正在编辑的记录的主键值，但没有任何成功
任何帮助将不胜感激，

答案 0 :(得分：0)
我认为你应该发送记录ID进行验证。
function check_email(value, colname) {
var rowid = jQuery('#personal').jqGrid('getGridParam', 'selrow');
$.ajax({
url: '@Url.Action("CheckEmail")',
data: { email: value, rowid: rowid },
type: 'POST',
async: false,
datatype: 'text',
success: function (data) {
if (!data) result = [true, ""];
else result = [false, colname + ": ya existe en el sistema"];
}
})
return result;
}
所以服务器有任何记录可以检查，ID与rowid不匹配。
