Introduction
This article is particularly relevant to you if you are creating a SharePoint app using JavaScript and the Client side object model. In the development of such an app, we would require some basic properties- SharePoint provides these with the _spPageContextInfo object.
_*** spPageContextInfo ***will provide these below properties:
- webServerRelativeUrl
- webAbsoluteUrl
- siteAbsoluteUrl
- serverRequestPath
- layoutsUrl
- webTitle
- webTemplate
- tenantAppVersion
- isAppWeb
- webLogoUrl
- webLanguage
- currentLanguage
- currentUICultureName
- currentCultureName
- env
- nid
- fid
- clientServerTimeDelta
- updateFormDigestPageLoaded
- siteClientTag
- crossDomainPhotosEnabled
- webUIVersion
- webPermMasks
- pagePersonalizationScope
- userId
- userLoginName
- systemUserKey
- alertsEnabled
- siteServerRelativeUrl
- allowSilverlightPrompt
- themedCssFolderUrl
- themedImageFileNames
Implementation
You can also access this object in JavaScript model as:
<script type="text/javascript">
var propertyValue = _spPageContextInfo.PropertyName
</script>
Example
Get current login user name
<script type="text/javascript">
var loginName = _spPageContextInfo.userLoginName
alert(loginName)
</script>
The above example will show an alert of value current user login.
To check the properties and its value of _spPageContextInfo, browse a SharePoint web page and open its view source (HTML - right click on web page ? view page source) and find text "spPageContextInfo".
