Arcgis get parameter value and edit in JS before append to html

Question

I'm using ArcGIS javascript to pass some value from map service to front-end HTML.

I use ${parameter_name} syntax and pass it into HTML by

var html = [];
html.push('<div>Parameter value is ${parameter_name}</div>');
InfoTemplate.setContent(html);

So that my HTML page will show an InfoTemplate holding

 Parameter value is XXX

But now I want to get the value XXX and edit it before push it into html. How should I get the value in my javascript?

Answer 1

You can use a function in the parametrized template like this below:

myEditFunction = function(parameterValue) {
    //here you can edit the value before returning it
    return parameterValue;
}

var html = [];
html.push('<div>Parameter value is ${parameter_name:myEditFunction}</div>');
InfoTemplate.setContent(html);

See the documentation vor API v3.26: https://developers.arcgis.com/javascript/3/jshelp/intro_formatinfowindow.html especially the Using custom functions section.
