createElementTwoWayLink

Class: slreportgen.webview.EmbeddedWebViewDocument
Namespace: slreportgen.webview

Element link and anchor in embedded Web view report

Syntax

elem2link = createElementTwoWayLink(wvdoc,ehandle,domlabel)


Description

elem2link = createElementTwoWayLink(wvdoc,ehandle,domlabel) creates a two-way connection between a Simulink^® Web view element and a DOM object in an embedded Web view Document panel. The elem2link DOM object is updated to include attributes that identifies it as a link. The elem2link DOM object is of the same type as domlabel or if domlabel is a string, an mlreportgen.DOM.Text object is created.

Input Arguments

wvdoc — Web view document

slreportgen.webview.WebViewDocument object

Web view document, specified as an slreportgen.webview.WebViewDocument object.

ehandle — Handle of Web view element anchor

character vector | object handle

Handle of Web view element anchor, specified as a character vector of the path or as an object handle. You can use the getExportDiagrams method to obtain the element paths and handles.

Example: Character vector: 'slrgex_vdp/Mu'. Object handle: get_param('slrgex_vdp/Mu','handle')

domlabel — DOM object from which to link

DOM object | character vector

DOM object from which to link, specified as a valid DOM object or as a character vector. If you enter a character vector, an mlreportgen.DOM.Text object is created.

Output Arguments

elem2link — Element link and Web view anchor

DOM object

Element link and Web view anchor, returned as a DOM object. The elem2link object connects a DOM object in the embedded Web view Document panel to the specified Simulink Web view element. The DOM object is updated with an attribute that indicates it is a link to the anchor.

Examples

Create Two-Way Element Link in Embedded Web View Report

Use CreateElementTwoWayLink to create two-way links between block names in the document pane and blocks in the diagram in the embedded web view. This example also uses createDiagramTwoWayLink to create links between level two headings in the document pane and diagrams in the embedded web view.

Run the following command to access the supporting files used in this example.

openExample('rptgenext/SimulinkReportGeneratorFilesExample');

Write a class, ExampleWebView, that is a subclass of slreportgen.webview.EmbeddedWebViewDocument. Use CreateElementTwoWayLink and createDiagramTwoWayLink in the fillContent method.

classdef ExampleWebView< slreportgen.webview.EmbeddedWebViewDocument
    
    methods
        function wvdoc = ExampleWebView(reportPath,modelName)
            % Invoke the EmbeddedWebViewDocument constructor, which
            % saves the report path and model name for use by the
            % report's fill methods.
            [e-mail](reportPath,modelName);
        end
        
        function fillContent(wvdoc)
            % Fill the Content hole in the report template with design
            % variable information. You can use DOM or Report API methods
            % to create, format, add, and append content to this report.
            
            [~, handles] = getExportDiagrams(wvdoc);
            
            n = numel(handles);
            for i = 1:n
                diagHandle = handles{i};
                diagHeading = createDiagramTwoWayLink(wvdoc,diagHandle, ...
                    mlreportgen.dom.Heading(2,get_param(diagHandle,'Name')));
                append(wvdoc,diagHeading);
                
                blockFinder = slreportgen.finder.BlockFinder(diagHandle);
                
                while hasNext(blockFinder)
                    r = next(blockFinder);
                    elemHandle = r.Object;
                    elemHeading = createElementTwoWayLink(wvdoc,elemHandle, ...
                        mlreportgen.dom.Heading(3,get_param(elemHandle,'Name')));
                    
                    append(wvdoc,elemHeading);
                end
                
            end
        end
    end
end

Create an object of the ExampleWebView class and use its methods to generate the embedded web view report.

model = 'slrgex_vdp';
open_system(model);
wvdoc = ExampleWebView('myReport',model);
open(wvdoc);
fill(wvdoc);
close(wvdoc);
rptview(wvdoc);
