Label Definition / Expression

jaykapalczynski

Anyone know if and how I can create the Label expression that puts the values on 2 lines?

"expression":"$feature.Owner1 + ' GO TO NEXT LINE  ' + $feature.MapNumber "

LabelDefinition <SPAN class="punctuation token">{</SPAN>
   json<SPAN class="punctuation token">:</SPAN> <SPAN class="punctuation token">{</SPAN>
      <SPAN class="string token">"labelExpressionInfo"</SPAN><SPAN class="punctuation token">:</SPAN><SPAN class="punctuation token">{</SPAN>
         <SPAN class="string token">"expression"</SPAN><SPAN class="punctuation token">:</SPAN><SPAN class="string token">"$feature.Owner1 + '  ' + $feature.MapNumber "</SPAN>
      <SPAN class="punctuation token">}</SPAN><SPAN class="punctuation token">,</SPAN>
                
<SPAN class="comment token">// SNIP</SPAN>

<SPAN class="punctuation token">}</SPAN>  <SPAN class="comment token">// END OF LAYER DEFINITION‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

So the LabelDefinition takes JSON object based on this doc, LabelDefinition QML Type | ArcGIS for Developers, so I assume it would be something like "\\n"

See this, javascript - How do I handle newlines in JSON? - Stack Overflow

Glad that it works. You need to escape the "\" in the string (turning it into a double-"\")

Yea thats what I was referencing....looked everywhere...every place I looked and found something it was \n

no where did i see if referenced with two \\ as your example \\n

But that seems to have worked...

// NO
"expression":"$feature.Owner1 + '\n' + $feature.MapNumber"


// YES
"expression":"$feature.Owner1 + '\\n' + $feature.MapNumber"<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>
