Sharepoint学习笔记—ECMAScript对象模型系列-- 3、如何查看SP object的所有方法(method)
在使用ECMAscript对象模型开发应用时,我们不自觉的想要知道某个SP object都提供了什么方法?这里我们就来看看怎么做。
1、在我们前面建立的Sharepoint项目中,新增一个Visual
WebPart(命名为WPLkECMAscript)和一个Javascript文件(命名为ECMAOpListItems.js)
ECMAOpListItems.js的代码如下,这段代码我们在前面的介绍中用到,主要用于提取WebSite的属性
//Retrive Website Properties
var siteUrl = '/';
function retriveWebSiteProperties() {
var clientContext = new SP.ClientContext(siteUrl);
// var clientContext= new SP.ClientContext.get_current();
this.oWebsite = clientContext.get_web();
clientContext.load(this.oWebsite, 'Title', 'Created'); //Load the specific properties of website object
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceededProperties),
Function.createDelegate(this, this.onQueryFailedProperties));
}
function onQuerySucceededProperties(sender, args) {
alert('Title: ' + this.oWebsite.get_title() + ' Created: ' + this.oWebsite.get_created());
// alert('Title');
}
function onQueryFailedProperties(sender, args) {
alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
// alert('Failed');
}
var siteUrl = '/';
function retriveWebSiteProperties() {
var clientContext = new SP.ClientContext(siteUrl);
// var clientContext= new SP.ClientContext.get_current();
this.oWebsite = clientContext.get_web();
clientContext.load(this.oWebsite, 'Title', 'Created'); //Load the specific properties of website object
clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceededProperties),
Function.createDelegate(this, this.onQueryFailedProperties));
}
function onQuerySucceededProperties(sender, args) {
alert('Title: ' + this.oWebsite.get_title() + ' Created: ' + this.oWebsite.get_created());
// alert('Title');
}
function onQueryFailedProperties(sender, args) {
alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
// alert('Failed');
}
在WPLkECMAscript的WPLkECMAscript.cs中注册我们上面加入的ECMAOpListItems.js,代码如下:
using System;
using System.ComponentModel;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;
namespace JsomTest.WPLkECMAscript
{
[ToolboxItemAttribute(false)]
public class WPLkECMAscript : WebPart
{
// Visual Studio might automatically update this path when you change the Visual Web Part project item.
private const string _ascxPath = @"~/_CONTROLTEMPLATES/JsomTest/WPLkECMAscript/WPLkECMAscriptUserControl.ascx";
protected override void CreateChildControls()
{
Control control = Page.LoadControl(_ascxPath);
Controls.Add(control);
ScriptLink.Register(this.Page, "/_layouts/JsomTest/ECMAOpListItems.js", true);
}
}
}
using System.ComponentModel;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;
namespace JsomTest.WPLkECMAscript
{
[ToolboxItemAttribute(false)]
public class WPLkECMAscript : WebPart
{
// Visual Studio might automatically update this path when you change the Visual Web Part project item.
private const string _ascxPath = @"~/_CONTROLTEMPLATES/JsomTest/WPLkECMAscript/WPLkECMAscriptUserControl.ascx";
protected override void CreateChildControls()
{
Control control = Page.LoadControl(_ascxPath);
Controls.Add(control);
ScriptLink.Register(this.Page, "/_layouts/JsomTest/ECMAOpListItems.js", true);
}
}
}
而WPLkECMAscript界面中我们添加了一个按钮来激活上面的功能,代码如下:
<br />
<input id="btnretrieveWebSiteProperties" type="button" value="RetrieveWebSiteProperties"
onclick='retriveWebSiteProperties()' />
<input id="btnretrieveWebSiteProperties" type="button" value="RetrieveWebSiteProperties"
onclick='retriveWebSiteProperties()' />
项目下所示:
2、在Sharepoint网站中添加上述开发的Visual WebPart,并运行Sharepoint应用,当应用界面显示时,所示如下图
3、调用IE的Developer Tools工具,如下
4、选中Developer Tools的Script页
5、选中你要调试的Javascript文件,这里我们是要调试ECMAOpListItems.js,所以选择它。
6、然后在此Javascrip代码中设置断点,选中Developer Tools上的Start Debugging,并运行我们网页上的功能按钮
7、在断点处选择我们感兴趣的对象,并查看它们的方法。
