添加後的面料畫布字體樣式更改

Question

我的意圖是通過選擇字體類型來改變字體，我將如何通過選擇即時更改字體。

我改變字體代碼：

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

有，因爲你應該包括jQuery的onload事件裏面的所有腳本：

Your fixed example

嘗試自己在下面的代碼片段，如果解決方案適合你：

$(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(); 
 
    }); 
 
});
