-# xDashApi
-
-xDashApi provides features for building multi-dashboard applications.
-
-Its main feature is to allow navigation between Chalk'it pages with parameter transfer. When landing at the target page, specified dataNodes of type *Variable* can have their initial values modified, as described below.
-
-xDashApi currently runs with JavaScript-type dataNodes.
-
-## goToPage
-
-In [constrained dashboard mode](../export/export#scaling-methods-for-the-constrained-dashboard), the method:
-
-```JavaScript
-xDashApi.goToPage(pageNumber)
-```
-
-allows to show only the targed page. It is the main method for building multi-page app with custom navigation control.
-
-## viewPage
-
-```JavaScript
-xDashApi.viewPage(pageUrl, inputVals, bNewTab)
-```
-
-Navigates to *pageUrl*, setting the values of the specified dataNodes in inputVals.
-
-- pageUrl : target page URL
-- inputVals : an array of structures of type
-  ```JSON 
-  {"dsName": "dataNodeName", "dsVal" : "dataNodeValue"}
-  ```
-  dsName should be of type string. dsVal can be of any JavaScript primitive type (number, string, boolean), array or JSON.
-- bNewTab : open in new tab when true.
-
-## viewProject
-
-Similar to view page, but applies for projects.
-
-```JavaScript
-xDashApi.viewProject(projectUrl, inputVals, bNewTab)
-```
