如何在具有母版页的页面中打开jQuery UI对话框？

Question

I want to open a jQuery UI Dialog from a asp.net page with master page. In a page within master page the code works fine but with master page doesn't work.

The code is:

<%@ Page Title="" Language="vb" AutoEventWireup="false"   MasterPageFile="~/privado/master/interior.master" CodeBehind="WebForm3.aspx.vb" Inherits="ProyectoDemo.WebForm3" %>
<asp:Content ID="Content1" ContentPlaceHolderID="headInterior" runat="server">
    <link type="text/css" href="Styles/jquery-ui-1.8.16.custom.css"    rel="stylesheet" />  
    <link href="Styles/addhunters.css" rel="stylesheet" type="text/css" />
    <script type="text/javascript" src="js/jquery-1.6.2.min.js"></script>
    <script type="text/javascript" src="js/jquery-ui- 1.8.16.custom.min.js"></script>
    <style type="text/css">
        /*demo page css*/
        body{ font: 62.5% "Trebuchet MS", sans-serif; margin: 50px;}
        .demoHeaders { margin-top: 2em; }
        #dialog_link {padding: .4em 1em .4em 20px;text-decoration:  none;position: relative;}
        #dialog_link span.ui-icon {margin: 0 5px 0 0;position: absolute;left: .2em;top: 50%;margin-top: -8px;}
        ul#icons {margin: 0; padding: 0;}
        ul#icons li {margin: 2px; position: relative; padding: 4px 0; cursor: pointer; float: left;  list-style: none;}
        ul#icons span.ui-icon {float: left; margin: 0 4px;}
    </style>    
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="contenidoInterior" runat="server">
    <script type="text/javascript">
        $(function () {
            // Dialog      
            $('#dialog').dialog({
                autoOpen: false,
                width: 600,
                height: 400,
                buttons: {
                    "Ok": function () {
                        $(this).dialog("close");
                    },
                    "Cancelar": function () {
                        $(this).dialog("close");
                    }
                }
            });
            // Dialog Link
            $('#Boton').click(function () {
                $('#dialog').dialog('open');
                return false;
            });
        });
    </script>

    <div id="uno">
        <h2 class="demoHeaders">Dialog</h2>        
        <asp:TextBox ID="TextBox1" runat="server" Text="prueba" ></asp:TextBox>
        <p><a href="#" id="dialog_link" class="ui-state-default ui-corner-all"><span class="ui-icon ui-icon-newwin"></span>Open Dialog</a></p>              
        <asp:LinkButton ID="Boton" runat="server">LinkButton</asp:LinkButton>
        <asp:Button ID="Button1" runat="server" Text="Button" />
        <!-- ui-dialog -->
        <div id="dialog" title="Dialog Title">
            <p>Dialog text</p>            
        </div>  
    </div>

I think the problem is how to refer to "dialog" within placeholder. I tried with several ways but I don't find the solution.

Anybody knows how to solve this issue?

Thank you in advance!

Answer 1

There are several things that you need to consider:

1. Add following code to a separate common.js and add it's reference to master page:

window["common"] = {
    liveDialog: function(btnId) {
         $(btnId).live(click,common.showDialog);
         return false;
    },
    showDialog() : function(){
         $('#dialog').dialog({
                autoOpen: false,
                width: 600,
                height: 400,
                buttons: {
                    "Ok": function () {
                        $(this).dialog("close");
                    },
                    "Cancelar": function () {
                        $(this).dialog("close");
                    }
                }
            });

    }

}

1. Add following method to master page:

public void RegisterDialog(clientBtnId)
{
    this.page.ClientScript.RegisterStartupScript(this.Page.GetType(),"__registerDialg","common.liveDialog('"+clientBtnId+"');",true);
}

1. From your content page, cast this.MasterPage to actual class name of your master page and pass your button's clientId to RegisterDialog.

--edited example --

For example your master page class name is CustomSiteMaster, you can write ((CustomSiteMaster)this.Master).RegisterDialog(button1.ClientID); -- end of edit --

It will work without problem

Answer 2

Add to LinkButton OnClientClick property as below:

<asp:LinkButton ID="Boton" runat="server" 
OnClientClick="$('#dialog').dialog('open'); return false;" >LinkButton</asp:LinkButton>

Also, if you want to select server-side control by id use following selector syntax:

$("#<%= ControlID.ClientID %>")

Answer 3

要在内容占位符中找到任何控件，请确保使用如下语法：

$('#ContentPlaceHolderId_ControlId')

Answer 4

jQuery UI is not being loaded because your src attribute has a additional space in it:

 <script type="text/javascript" src="js/jquery-ui- 1.8.16.custom.min.js"></script>

Just change to:

<script type="text/javascript" src="js/jquery-ui-1.8.16.custom.min.js"></script>

And jQuery UI might load fine and you will stop receiving "the object does not support this property or method" messages.

Answer 5

I have the solution to the "mistery". The problem is very simple. The references to .js files of jQuery-UI are in Conten1 placeholder, I put this two lines in Conten2 placeholder, this content has a javascript function in order to open the dialog.

The complete and working code is the following:

<%@ Page Title="" Language="vb" AutoEventWireup="false"   MasterPageFile="~/privado/master/interior.master" CodeBehind="WebForm3.aspx.vb"   Inherits="ProyectoDemo.WebForm3" %>
<asp:Content ID="Content1" ContentPlaceHolderID="headInterior" runat="server">
    <link type="text/css" href="Styles/jquery-ui-1.8.16.custom.css"    rel="stylesheet" />  
    <link href="Styles/addhunters.css" rel="stylesheet" type="text/css" />
    <%--<%@ MasterType  VirtualPath="~/privado/master/Interior.master"%>--%>
    <style type="text/css">
        /*demo page css*/
        body{ font: 62.5% "Trebuchet MS", sans-serif; margin: 50px;}
        .demoHeaders { margin-top: 2em; }
        #dialog_link {padding: .4em 1em .4em 20px;text-decoration:    none;position: relative;}
        #dialog_link span.ui-icon {margin: 0 5px 0 0;position:   absolute;left: .2em;top: 50%;margin-top: -8px;}
        ul#icons {margin: 0; padding: 0;}
        ul#icons li {margin: 2px; position: relative; padding: 4px 0;   cursor: pointer; float: left;  list-style: none;}
        ul#icons span.ui-icon {float: left; margin: 0 4px;}
    </style>    
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="contenidoInterior" runat="server">
    <script type="text/javascript" src="js/jquery-1.6.2.min.js"></script>
    <script type="text/javascript" src="js/jquery-ui-   1.8.16.custom.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            alert('hola');
            $('#dialog').dialog({
                autoOpen: false,
                width: 600,
                height: 400,
                buttons: {
                    "Ok": function () {
                        $(this).dialog("close");
                    },
                    "Cancelar": function () {
                        $(this).dialog("close");
                    }
                }
            });

            $('#MainContent_contenidoInterior_Boton').click(function () {
                $('#dialog').dialog('open');
                return false;
            });
        });               
    </script>

    <div id="uno" >
        <h2 class="demoHeaders">Dialog</h2>        
        <asp:TextBox ID="TextBox1" runat="server" Text="prueba" ></asp:TextBox>
        <p><a href="#" id="dialog_link" class="ui-state-default ui-corner-all"><span class="ui-icon ui-icon-newwin"></span>Open Dialog</a></p>              
        <asp:LinkButton ID="Boton" runat="server">LinkButton</asp:LinkButton>
        <asp:Button ID="Button1" runat="server" Text="Button" />
        <!-- ui-dialog -->
        <div id="dialog" title="Dialog Title">
            <p>Dialog text</p>            
        </div>  
    </div>

Thank you for your answers.
