Question

我的意图是通过选择字体类型来改变字体，如何通过选择立即改变字体。

我的更改字体代码：

//the font wont change getAcriveObject
    $(function() {
       $('#FontStyleNumber').change(function(){
        var cFont = $(this).val();
        var tObj = canvas.getActiveObject();
        tObj.set({fontFamily : cFont});
        canvas.renderAll();
        });
    });

如果解决方案适合您，请尝试使用下面的代码：

$(function() {
  var canvas = new fabric.Canvas('textCanvas');

  var textObj1 = new fabric.Text('font test', {
    left: 100,
    top: 100,
    fontSize: 30,
    fill: "#FF0000" // Set text color to red
  });

  canvas.add(textObj1);
  $('#FontStyleNumber').change(function() {
    
    var mFont = $(this).val();
    var tObj = canvas.getActiveObject();
    tObj.set({
      fontFamily: mFont
    });
    canvas.renderAll();
  });
});
