将表单重置为Null或重新加载页面usign重置即使提交后也是如此 [英] Reset the form to Null or Reload the page usign reset even after a submit
问题描述
大家好，
这就是场景：
我有两个按钮 - 提交和重置
提交用于验证，验证通过后，将其传递给另一个表单进入数据库。
基本上，如果在使用表单中的提交按钮之前使用它，重置工作正常。例如，如果提交时存在一些错误，因为值未通过验证。显示错误弹出消息，并且值保留在字段中。现在，如果我使用重置，则字段的所有值都不会返回null。
我是表格验证新手。我在网上查了一下，它表示如果我们使用了提交，重置将无法清除，我们需要使用javascript来执行此操作。
所以我重置为一个按钮，onclick事件调用reset（）函数并清除表单，但我确信代码不对，因为它不工作，我累了在我的功能中发出一条警告信息，以重新启动函数被调用，但我认为不是。
发布我的代码
[代码]
< INPUT id = reset1 name = reset1 type = button value =重置onClick =" reset（）">
< Script>
function reset（）
{
alert（所有值现在应清除）;
document.frmUser.name ="" ;
document.frmUser.user ="" ;
document.frmUser.contactNumber ="" ;;
document.frmUser.email ="" ;
}
< / Script>
我不确定它是否是最好的方法。
我希望每次单击重置时刷新/重新加载整个表单，并且所有字段都没有值。
感谢您的帮助。

Hi everyone,
This is the scenario:
I have two button - Submit and Reset
Submit is used for validation and after validation is passed it passes it to another form to enter into database.
Bascially the reset works fine if I use it before using the submit button in the form. For instance,if on submit there is some error as the values have not passed a validation. There is a error pop up message shown and the values are retained in the field and Now if I use reset , all the values of the field do not go back to null.
I am new with form validation. I checked online and it said that reset will not clear if we have used submit and we need to use javascript to do it.
So I made reset into a button which onclick event calls the reset() function and clears the form but I am sure that the code is not right as it is not working, I tired putting a alert message in my fucntion to reassue that the function is being called but I think it is not.
Posting my code
[code]
<INPUT id=reset1 name=reset1 type =button value=Reset onClick="reset()">
<Script>
function reset()
{
alert ("all values shall be cleared now");
document.frmUser.name = "" ;
document.frmUser.user = "" ;
document.frmUser.contactNumber = "";
document.frmUser.email = "" ;
}
</Script>
I am not sure if its the best way to do it.
I want the whole form to refresh/ reload everytime reset is clicked and all the fields to have no values.
Thanks for the help in advance.

我正在使用ASP页面。我只是想在单击重置时将所有字段值设置为null。 Javascript教程提到了重置值，但我的IE浏览器说，不支持这个对象。所以我可能要将所有值都设置为null ???我不确定，实际上很困惑：D
I am using ASP page. Its just I want to set all the field values to null when we click reset. Javascript tutorials mention usign reset value but my IE browser says, does not support this object. So I may have to set all the values back to null??? I am nto sure, actually confused :D
就像表格有一个submit（）函数一样，它们有一个reset（）函数。你不必自己制作。
Just like forms have a submit() function, they have a reset() function. You don''t have to make your own.
