onclientclick

当我们点击一按钮，想要弹出一双选择提示框时，可以采用以下方法： <asp:Button ID="Button1" runat="server" Font-Bold="True" Font-Size="Large" Height="34px" onclick="Button1_Click" OnClientClick="return f_check_IP()" Text="添加记录" Visible="False" Width="150px" /> <script language="javascript" type="text/javascript"> function f_check_IP() { var msg = "您真的确定要添加新纪录吗？\n\n请确认！"; var shi = document.getElementById('Text2').value; var now_goods = document.getElementById('Text3').value; var a = /^[a-zA-Z][a-zA-Z]\d\d\d\d\d\d\d\d\d$/; var b = /^[a-zA-Z][a-zA-Z]\d\d\d\d\d\d\d\d\d(_|\/)(\d{1,4})([a-zA-Z][a-zA-Z])(-|\/)(\d{1,4})$/; if (1) { if

I have an asp:Button on my webpage, and it calls into a JavaScript function and a code-behind method. The latter makes a call to navigate to another page. In the JavaScript function, I'm checking for a condition. If this condition is not met, I want to abort the navigation so that the OnClick method is not called. Is this possible? <asp:Button OnClick="Button_Click" ID="Action1" OnClientClick="SaveValues()" Text="Action1" CssClass="specialButton" runat="server" /> Tim Schmelter To block OnClick from executing, just return false from OnClientClick : <asp:Button OnClick="Button_Click" ID=

my link button - <asp:LinkButton runat="server" ID="lbtnEdit" Text="edit" OnClientClick="javascript:msgDisp('<%# Eval(LocationId).toString() %>')" /> and the javascript msgDisp is- <script type="text/javascript" language="javascript"> function msgDisp(lid) { alert(lid); } </script> but it is not giiving LocationId in pop but the whole string <%#......%> is comin in popup message. How can I pass Eval values in javascript. You can build the entire contents of OnClientClick as a string within the code brackets and it will output like you're expecting. <asp:LinkButton runat="server" ID="lbtnEdit"

Okay, i think i've tried 3-4 methods here from stackoverflow, but none seems to work. I've got: OnClientClick='<%# Eval("albumName", "doConfirm(\"delete\", \"{0}\");").ToString() %>' but in html it renders as: onclick="doConfirm("delete", "Test");" Also tried making a method to call: public string CreateConfirmation(String action, String item) { return String.Format(@"return confirm('Sikker på du vil {0}: {1}');", action, item); } With this: OnClientClick='<%# CreateConfirmation("delete", (string)Eval(albumName)) %>' But gives me exact same problem.... So im pretty lost? pete I apologize in

I just want to add some client side (JQuery Javascript) validation in a web user control. I put an OnClientClick handler and the function gets called. BUT, even if I return "false", the OnClick method always get fired. What am I doing wrong ? I'm with VS 2010, targeting the 4.0 framework with JQuery 1.4.2. and JQuery UI 1.8.4. Here's a sample code : <td style="text-align:right"><asp:Button ID="btnAddSave" OnClientClick="return ValidateMail();" OnClick="btnAddSave_Click" runat="server" Text="Submit" /></td> Script method : function ValidateMail() { alert("Bouton clicked"); return false; } If I

I meet about problem to pass arguments to the client-side event OnClientClicking . I tried to use the String.Format () function, but it does not work. Do you have an idea for a workaround to send parameter linked with OnClientClicking ?

Does anyone know why a client-side javascript handler for asp:CheckBox needs to be an OnClick="" attribute rather than an OnClientClick="" attribute, as for asp:Button? For example, this works: <asp:CheckBox runat="server" OnClick="alert(this.checked);" /> and this doesn't (no error): <asp:CheckBox runat="server" OnClientClick="alert(this.checked);" /> but this works: <asp:Button runat="server" OnClientClick="alert('Hi');" /> and this doesn't (compile time error): <asp:Button runat="server" OnClick="alert('hi');" /> (I know what Button.OnClick is for; I'm wondering why CheckBox doesn't work

I have a form where a user can delete a record, and I want a pop up message where the user has to click okay to confirm the delete. Delete button: <asp:Button ID="btnDelete" runat="server" Text="Delete" UseSubmitBehavior="false" OnClick="btnDelete_Click" OnClientClick="confirmation();" /> Confirmation function: function confirmation() { var answer = confirm("Are you sure you want to delete? This action cannot be undone.") } So right now, clicking the delete button executes the btnDelete_Click Sub in the code behind regardless of whether you click okay or cancel in the pop up box. I know I can
