Introduction/Catalog
Please download the sample code at the section <span class="zblog-section">JQueryElement </span>demo download of Download JQueryElement, the directory is /resourceloader/Default.aspx.
This article explains how to use the ResourceLoader to add scripts and styles to page:
- Prepare
- Define Path
- JQuery UI Controls
- JQPlot Control
- Specify the Required Scripts and Styles
- Custom Controls
Prepare
Be sure that you have got the latest version of JQueryElement at the section JQueryElement.dll download of download JQueryElement.
Use the following statements to reference namespace:
<%@ Register Assembly="zoyobar.shared.panzer.JQueryElement"
Namespace="zoyobar.shared.panzer.ui.jqueryui"
TagPrefix="je" %>
Define Path
First, you need to define the path of the script or style in the web.config:
<appSettings>
<add key="je.jquery.js" value="<jquery script path>"/>
<add key="je.jquery.ui.js" value="<jquery ui script path>"/>
<add key="je.jquery.ui.css" value="<jquery ui style path>"/>
<add key="je.jqplot.excanvas.js" value="<jqplot excanvas script path>"/>
<add key="je.jqplot.js" value="<jqplot script path>"/>
<add key="je.jqplot.<widget>.js" value="<jqplot widget script path>"/>
...
<add key="je.jqplot.css" value="<jqplot style path>"/>
<add key="<custom key>" value="<path>"/>
</appSettings>
<appSettings>
<add key="je.jquery.js"
value="~/js/jquery-1.6.2.min.js"/>
<add key="je.jquery.ui.js"
value="~/js/jquery-ui-1.8.15.custom.min.js"/>
<add key="je.jquery.ui.css"
value="~/css/smoothness/jquery-ui-1.8.15.custom.css"/>
<add key="je.jqplot.excanvas.js"
value="~/js/excanvas.min.js"/>
<add key="je.jqplot.js"
value="~/js/jquery.jqplot.min.js"/>
<add key="je.jqplot.DateAxisRenderer.js"
value="~/js/plugins/jqplot.dateAxisRenderer.min.js"/>
...
<add key="je.jqplot.css"
value="~/css/jquery.jqplot.min.css"/>
<add key="my.key" value="~/js/my.js"/>
</appSettings>
In web.config, use specific keywords to jQuery, jQuery UI and jqplot scripts and styles.
You can add custom keywords to represent your own files. These keywords will be used in a custom control.
JQuery UI Controls
In the page, we add a ResourceLoader control, and then add a JQueryElement control, such as a button:
<head runat="server">
<title>JQuery UI Controls</title>
</head>
...
<je:ResourceLoader ID="resource" runat="server" />
<je:Button ID="button" runat="server" Label="A Button">
</je:Button>
In the above example, you do not need to add the scripts and styles of jQuery UI, because the ResourceLoader will add these scripts and styles.
JQPlot Control
You also need to add the ResourceLoader Control, but if you use jqplot widget, you also need to set some properties of ResourceLoader:
<je:ResourceLoader ID="resource" runat="server"
JQPlotDateAxisRenderer="true" />
<je:Plot ID="plot1" runat="server" IsVariable="true">
<AxesSetting XAxisSetting-Renderer="DateAxisRenderer">
</AxesSetting>
<DataSetting>
<je:Data>
<je:Point Param1="'2011-1-1'" Param2="300" />
<je:Point Param1="'2011-1-2'" Param2="320" />
<je:Point Param1="'2011-1-3'" Param2="340" />
<je:Point Param1="'2011-1-4'" Param2="400" />
</je:Data>
</DataSetting>
</je:Plot>
In the code above, we use the jqplot date axis widget, so you need to set the property JQPlotDateAxisRenderer to true.
About the settings of different jqplot widgets, please refer to the related article of jqplot.
Specify the Required Scripts and Styles
Through the JQuery, JQueryUI, JQPlot properties of ResourceLoader control to add the scripts and styles:
<je:ResourceLoader ID="resource" runat="server"
JQueryUI="true" />
In the above code, set the JQueryUI property to true, the page will be added to the scripts and styles of jQuery UI.
Custom Controls
You can specify the required scripts and styles for the custom control:
using zoyobar.shared.panzer.ui.jqueryui;
[Resource ( SingleScript = "my.js", SingleStyle = "my.css" )]
public partial class resourceloader_MyControl
: System.Web.UI.UserControl
{
...
}
Use SingleScript and SingleStyle properties of ResourceAttribute to specify the keyword of the script and style. These keywords have been specified in the web.config:
<appSettings>
<add key="my.js"
value="~/resourceloader/mycontrol.js"/>
<add key="my.css"
value="~/resourceloader/mycontrol.css"/>
...
</appSettings>
You can specify more than one script or style, separated by semicolons. For a custom file, the keyword order is the load order of files.
You can also use the MultipleScript property to specify the required scripts, if the keywords in MultipleScript are specified in web.config, SingleScript will be ignored:
<%@ Control Language="C#" AutoEventWireup="true"
CodeFile="MyControl2.ascx.cs"
Inherits="resourceloader_MyControl2" %>
<input type="button" class="my-button"
onclick="alert(add(1,2));"
value="1 + 2" />
using zoyobar.shared.panzer.ui.jqueryui;
[Resource ( SingleScript = "my.js",
MultipleScript="my1.js", SingleStyle = "my.css" )]
public partial class resourceloader_MyControl2
: System.Web.UI.UserControl
{
...
}
<appSettings>
<add key="my.js" value="~/resourceloader/mycontrol.js"/>
<add key="my1.js" value="~/resourceloader/mycontrol.1.js"/>
<add key="my2.js" value="~/resourceloader/mycontrol.2.js"/>
<add key="my.css" value="~/resourceloader/mycontrol.css"/>
...
</appSettings>
