工作学习 / IT技术讨论 / How to realize such a function in ASP? Every web programmer, especially,Rootbear, gives me some ideas. Thanks a lot, a lot.When visitor submits a form with several fields missed, an error message and return button displays, then the visitor clicks the return button to go back. In this case, the data he entered before should not lost.How to redisplay these data in the form? GAO SHOU please show me how to do it in ASP files? Thanks a lot.

javascriptsample:
<Script language="Javascript">
function check_field(){
if (document.formname.field_name==""){
alert("please fill up the field_name value")
return false
}
else {
return true;
}
}
</Script>
----
HTML
<form name=form_name action="action.asp" onSubmit="return check_field()">

That method works. But you don' t know how to adapt it to your codes! Javascript is capable of perform regular expression check and lots of other type of checks on form fields. Read documentations!

比较简单的方法是，在第二页也build相应的fields，但是类型用HIDDEN，用户看不见，你把前页的值带过来，如果go back, 再把值copy回去。

虽然简单，但不是最好的方法。Java script的history应该可以。

history back 应该是最简单有效的方法。

That's harder for placing a check in the first place when you submit the stuffs.
