The 'target ='_blank'' HTML tag is ignored in geoprocessing services when embedding in web applications created in ArcGIS Online.

Additional Information

Workaround

• The output of the geoprocessing tool is of type GPString and the tool generates an HTML element <a> directly.
• To keep out the malicious code, string content is sanitized before displaying on the page and the target=‘_blank’ is removed.
• Open a new tab to show the output PDF file, change the output type of the geoprocessing tool from GPString to GPDataFile.
• Thus, ArcGIS Web AppBuilder will generate an HTML element <a target=“_blank”>.
• If the output type is GPDataFile, the users do not need to generate the URL parameter.
• Set the output file path as the value of GPDataFile. The geoprocessing service will create a URL for it. The print service is a good example, refer to the following link, http://sampleserver6.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task for more information.
