I have created a registration form in asp. net 3.5. I have written a javascript to perform validations on form elements. On form submit event i have called to javascript functon. When i click on submit button its working properly. But when i click on reset button then also the form is being validating. So how should i write code to not validate form when i click on REset button. Please help me...

推荐答案

创建另一个JavaScript函数以进行重置以清除所有字段，并在onclientclick中调用该函数..

create another javascript function for the reset to clear all the fields and in onclientclick call that function ..

function clear()
{

document.getElementById('<%=txtbox1.ClientID%>').value="";
document.getElementById('<%=txtbox2.ClientID%>').value="";
document.getElementById('<%=txtbox3.ClientID%>').value="";        
document.getElementById('<%=txtbox4.ClientID%>').value="";
}

这是重置按钮，您可以通过这种方式致电

this is reset button in this way you can call

 <asp:imagebutton id="imgbtnReset" runat="server" imageurl="~/images/reset_btn.gif" xmlns:asp="#unknown">
                                                                            OnClick="imgbtnReset_Click" OnClientClick="javascript:return clear();" />
</asp:imagebutton>

您需要将按钮的CausesValidation属性设置为false.此属性的Default value是true.

示例:

You need to set the CausesValidation property of the button false. Default value for this property is true.

Example :

<asp:button causesvalidation="TRUE|FALSE" runat="server" xmlns:asp="#unknown" />

Hope this helps.
All the best.

您可以使用OnClick事件代替OnSubmit.

Instead of OnSubmit, you can use OnClick event.

<button onclick="document.getElementById('field2')">Submit here</button>
