    }
}
  • Add highlight for textbox object
    addHighlight(startpostion,endposition)
    // the parameters are:
	startpostion: highlight start postion in textbox
	endpostion: highlight end postion in textbox

//for example,we assume shape 0 is a textbox object
const textbox=xs.sheet.data.shapes[0];
//first we shall add to highlight shape to enable the highlight for the textbox shape object,it support multiple range postion 
 xs.sheet.addHighlightShape(textbox.id);
 textbox.addHighlight(5,10);
 textbox.addHighlight(18,28);
  • Remove highlight for textbox object
    removeHighlight(startpostion,endposition)
    // the parameters are:
	startpostion: highlight start postion in textbox
	endpostion: highlight end postion in textbox
    //for example,we assume shape 0 is a textbox object
     const textbox=xs.sheet.data.shapes[0];
     textbox.removeHighlight(5,10);
  • Get highlight for textbox object
    getHighlight()
    //for example,we assume shape 0 is a textbox object
     const textbox=xs.sheet.data.shapes[0];
