asp:LinkButton -验证表单字段
本文关键字：表单 字段 验证 LinkButton asp | 更新日期: 2023-09-27 18:02:11
我对c#完全陌生，我正试图弄清楚表单验证。更具体地说，我有一个webform (c#)，我把它分成了"form-part-1"answers"form-part-2"两个部分。
默认情况下，form-part-2是隐藏的。当"表格-1"的所有栏位填妥后，你可以按"继续"连结按钮继续"表格-2"。
jQuery部分工作得很好，可以按需要显示和隐藏表单部分。但是验证不再强制执行。
我已经准备好了验证器，但是现在我可以继续"form-part-2"，而不需要填写"form-part-1"字段。
我希望在进行"form-part-2"之前执行验证。
如果有什么建议，我将不胜感激。
提前感谢。
下面是我的代码:
<script language="javascript" type="text/javascript">
$(document).ready(function () {
$("#continue").click(function (event) {
$('#form-part-1').hide();
$('#form-part-2').fadeIn();
});
});
</script>
<form id="SignUp" method="post" runat="server">
<table id="validation">

<td colspan="2" vAlign="top">

<table id="form-part-2">

* * * * 编辑:
谢谢Phx &丹尼尔，谢谢你的反馈。很有帮助!一切都很顺利，只有一个例外。在进入步骤2之前，"form-part-2"字段就得到了验证。如何验证用户名/密码字段只有在我得到"form-part-2"吗?提前感谢!

正如您所写的:我希望在进行"form-part-2"之前强制执行验证。
您需要创建验证组来验证前N个字段和另外N个字段。因此，为控件创建验证组:
http://msdn.microsoft.com/en-us/library/vstudio/ms227424 (v = vs.100) . aspx
<asp:textbox id="AgeTextBox"
runat="Server">
</asp:textbox>
<asp:requiredfieldvalidator id="RequiredFieldValidator2"
controltovalidate="AgeTextBox"
validationgroup="PersonalInfoGroup"
errormessage="Enter your age."
runat="Server">
</asp:requiredfieldvalidator>
<!--When Button1 is clicked, only validation
controls that are a part of PersonalInfoGroup
are validated.-->
<asp:button id="Button1"
text="Validate"
causesvalidation="true"
validationgroup="PersonalInfoGroup"
runat="Server" />
<asp:textbox id="CityTextBox"
runat="Server">
</asp:textbox>
<asp:requiredfieldvalidator id="RequiredFieldValidator3"
controltovalidate="CityTextBox"
validationgroup="LocationInfoGroup"
errormessage="Enter a city name."
runat="Server">
</asp:requiredfieldvalidator>
<!--When Button2 is clicked, only validation
controls that are a part of LocationInfoGroup
are validated.-->
<asp:button id="Button2"
text="Validate"
causesvalidation="true"
validationgroup="LocationInfoGroup"
runat="Server" />
然后对每个组使用不同的验证摘要。
也许你需要一个按钮为每个验证，但你可以这样做，并使用相同的按钮为多个验证组:
http://www.aspsnippets.com/Articles/Validate-Multiple-Validation-Groups-with-one-Button-in-ASPNet.aspx另一个例子http://www.codeproject.com/Tips/401611/Validate-multiple-Validation-group-both-client-and
Phx给出了部分答案。使用他的建议来创建ValidationGroups。将第1部分和第2部分中的所有验证器放在不同的组中。
JQuery不自动触发验证
您需要用JavaScript手动调用验证。这可以通过调用Page_ClientValidate来完成，它将验证传递的ValidationGroup的所有验证器。
$("#continue").click(function (event) {
if (Page_ClientValidate("group1")) {
$('#form-part-1').hide();
$('#form-part-2').fadeIn();
}
});
