Hi Folks

The below example not woking in illustror. Initially I applied underline = true for the textrange working fine but while removing its not working. Please help on this.

var doc = app.activeDocument;
for (var i = 0; i < doc.textFrames.length; i++) {
var txtFrame = doc.textFrames[i];
var textRange = txtFrame.story.textRange;
textRange.start = 0;
textRange.length = 5;
textRange.characterAttributes.underline = false;
}
Thanks in advance

Correct answer sttk3
As for CharacterAttributes.underline, the result is caused by Illustrator's specification that it is ignored if we set the same value as the character style being applied.

The following script has a workaround function setUnderline to avoid this. Instead of just setting the underline property, try specifying it via setUnderline.
(function() {
  var doc = app.activeDocument ;
  for(var i = 0; i < doc.textFrames.length; i++) {
    var txtFrame = doc.textFrames[i] ;
    var textRange = txtFrame.story.textRange ;
    textRange.start = 0 ;
    textRange.length = 5 ;
    
    setUnderline(textRange, false) ;
  }
})() ;

function setUnderline(textRange, dstUnderline) {
  var appliedCharacterStyle = textRange.characterStyles[0] ;
  var styleUnderline = appliedCharacterStyle.underline ;

  if(styleUnderline === dstUnderline) {
    appliedCharacterStyle.underline = !styleUnderline ;
    textRange.underline = dstUnderline ;
    appliedCharacterStyle.underline = styleUnderline ;
  } else {
    textRange.underline = dstUnderline ;
  }
}

    Thanks @sttk3 that workaround is nice! I tried it with my test script and it worked. (I still consider this behaviour as a bug, by the way.)

      It was possible to specify this correctly until Illustrator CS3. I would consider it a bug too.

      Hi @Jothi Sankar Anand S I think you have found a bug. I have posted a bug report. Please vote on it.

       

      Here is my test script:

      /**
 * @author m1b
 * @discussion https://community.adobe.com/t5/illustrator-discussions/removing-underline-not-working-in-illustrator-using-extendscript/m-p/14895226
 */
(function () {

    var doc = app.activeDocument,
        tf = doc.activeLayer.textFrames.add(),
        tr = tf.textRanges;

    tf.contents = 'ab';

    // change an attribute on the first character
    tf.textRange.characters[0].characterAttributes.baselineShift = 1;

    var results = ['Results:'];

    // test 1 on first character
    tr[0].characterAttributes.underline = true
    results.push('tr[0] underline = TRUE: '
        + (true === tr[0].characterAttributes.underline ? 'PASSED' : 'FAILED'));

    // test 2 on first character
    tr[0].characterAttributes.underline = false;
    results.push('tr[0] underline = FALSE: '
        + (false === tr[0].characterAttributes.underline ? 'PASSED' : 'FAILED'));

    // test 1 on second character
    tr[1].characterAttributes.underline = true;
    results.push('tr[1] underline = TRUE: '
        + (true === tr[1].characterAttributes.underline ? 'PASSED' : 'FAILED'));

    // test 2 on second character
    tr[1].characterAttributes.underline = false;
    results.push('tr[1] underline = FALSE: '
        + (false === tr[1].characterAttributes.underline ? 'PASSED' : 'FAILED'));

    app.redraw();
    alert(results.join('\n'));

})();

       

      And my results are:
