extendscript - How to replace selected text in InDesign via script? -

in scripted ui panel, have button supposed insert text. came routine, which, indeed, inserts whatever text wherever want, if there text selected, doesn't replace selection.

how can modify function replace selection? if there nothing selected, should insert text normally.

function inserttext(whattext){     if( app.selection.length < 1 ){ exit(); }     var tf = app.selection;     for( var q = 0; q < tf.length; q++ ){         var thisframe = tf[q];         var originaltext = thisframe.contents;         thisframe.contents = originaltext + whattext;     } } 

hmmm... well, seems work pretty well... [embarassed on face]

function inserttext(whattext){ app.selection[0].contents = whattext; }
