RequiredFieldValidator + Button =回傳！

Question

我有這個標記代碼：

<div id="rowIndirizzo" class="form"> 
    <label> 
     Indirizzo:</label> 
    <asp:DropDownList ID="ddlToponimo" CssClass="indirizzo" runat="server" DataTextField="Toponimo" 
     DataValueField="Toponimo"> 
    </asp:DropDownList> 
    <asp:TextBox ID="txtStrada" CssClass="textinputStrada" runat="server"></asp:TextBox> 
    <asp:TextBox ID="txtNumCivico" CssClass="textinputCivico" runat="server"></asp:TextBox> 
</div> 
<div id="divCap" class="form"> 
    <label> 
     CAP:</label> 
    <asp:TextBox ID="txtCAP" CssClass="textinputCAP" runat="server"></asp:TextBox> 
</div> 
<asp:RequiredFieldValidator ID="rfvToponimo" CssClass="errore2" runat="server" ControlToValidate="ddlToponimo" 
    ErrorMessage="Il campo toponimo dell'indirizzo è obbligatorio." Display="Dynamic" 
    ValidationGroup="Step4_StruttPrivata1Step" Style="color: Red; display: block !important;"></asp:RequiredFieldValidator> 
<asp:RequiredFieldValidator ID="rfvStrada" CssClass="errore2" runat="server" ControlToValidate="txtStrada" 
    ErrorMessage="Il campo strada dell'indirizzo è obbligatorio." Display="Dynamic" 
    ValidationGroup="Step4_StruttPrivata1Step" Style="color: Red; display: block !important;"></asp:RequiredFieldValidator> 
<asp:RequiredFieldValidator ID="rfvNumCivico" CssClass="errore2" runat="server" ControlToValidate="txtNumCivico" 
    ErrorMessage="Il campo numero civico dell'indirizzo è obbligatorio." Display="Dynamic" 
    ValidationGroup="Step4_StruttPrivata1Step" Style="color: Red; display: block !important;"></asp:RequiredFieldValidator> 
<asp:RequiredFieldValidator ID="rfvCAP" CssClass="errore2" runat="server" ControlToValidate="txtCAP" 
    ErrorMessage="Il campo CAP è obbligatorio." Display="Dynamic" 
    ValidationGroup="Step4_StruttPrivata1Step" Style="color: Red; 
    display: block !important;"></asp:RequiredFieldValidator> 
<asp:RegularExpressionValidator ID="revCAP" runat="server" ControlToValidate="txtCAP" 
    ValidationExpression="^([0-9]{5})$" ErrorMessage="Il formato del CAP è errato (Es.)" 
    Display="Dynamic" ValidationGroup="Step4_StruttPrivata1Step" Style="color: Red; 
    display: block !important;" /> 
<asp:Button ID="btnSearchIndirizzo" OnClientClick="return false;" class="buttonnext" runat="server" Text="Inserisci" 
    ValidationGroup="Step4_StruttPrivata1Step"></asp:Button> 

我有一定的控制，以驗證上按一下按鈕，但我不想回傳（我不能使用輸入按鈕，因爲不要火RFV）。我嘗試過使用onclientclick事件...但沒有。

Answer 1

更新：我修改了dummyFunction代碼以顯式激發客戶端驗證，並在頁面無效時停止回發。

嘗試在您的按鈕標記以下屬性

UseSubmitBehavior = false 

你可能也想嘗試

OnClientClick = "return dummyFunction();" 

，然後有一個JS功能dummyFunction如

function dummyFunction(){ 

//this command will explicitly fire the validation 
    Page_ClientValidate(); 
    return Page_IsValid; //Page_IsValid is set to true or false depending on whether a page is valid or not after client validation 
    } 

Answer 2

可以導致頁面在進一步onClientClick之前進行驗證我的意思是你可以從OnClientClick t觸發它帽子將執行必需的字段驗證程序。

就在您的客戶端點擊功能補充一點：

功能myOnClientClick（）

{

如果（Page_ClientValidate（））//這將觸發驗證

{

//然後做客戶的東西

}

}
