textbox is a special kind of shape which type property is :“TextBox”, for example: the below code will show which shape is textbox

    if (shape.type === 'TextBox') {
        console.log(shape.id + ' is a textbox');
    }
}
  • 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

        color: the html color value in hex string value

  • Auto change the background color and text color to get a visual active effect

    // the parameters are:
        boolvalue: if true,will change background color and the text color of the textbox object;if false,restore to original appearence
  • hide/unhide the text content in the textbox object
