Format info window content: Display text from a Double field

Question

Hi All, Thank you for your time in advance. I am wondering if anyone could provide valuable opinions how to display the text from a Double field in the info window (code listed below). I found some records have the zero value in the Double field ${WellDepth}. I want to see if anyone could provide a function to replace the 0 to display "Unknown Value" and keep the same value if the ${WellDepth} is greater than 0. Many thanks, Hank var content_magnesium_depthLocation =                   "PointID: ${POINT_ID}" +                   "
Date Collection: ${Collection}" +                   "
Magnesium Value: ${Mg_Symbol}${Mg}(mg/L)" +                   "
Well Depth: ${WellDepth}(ft)" +    "
Data Source: ${DataSource}" + "
Data Source Information: ${DataSour_1}" + "
More Information:Magnesium Info";

Chang-Heng, Here is an example function: function setContent(value) { var formatString = "Property Name: + value.attributes.PropertyName +"
" var sqft = geometryEngine.geodesicArea(value.geometry, "square-feet"); var squarefeet = number.format(sqft, { places: 1 }); var acres = number.format(sqft / 43560, { places: 0 }); formatString += "Acres: " + acres; return formatString; }

Hi Robert,

Thank you for the reply. I am wondering if you could provide more details on the function for this question.

Thanks,

Chang-Heng,

This is exactly one of the reasons why the InfoTemplates set setContent method can take a string or a function. Use a function to look at the features attribute value for WellDepth and if it is 0 then add text to the content string that is returned instead of the numeric value.
