私は自分のプロジェクトで数日前にこれを行いました。コードスニペットです。基本的に、最初に長方形を描画し、その中にテキスト領域を配置し、最後にそれを kinetic.text ノードに変換します。
drawText: function ( color )
{
var layer1=this.model.stage.getLayers()[0];
var $this=this;
console.log('drawText: color: ' + color);
if($this.rectangleDrawn==true)
{
var down = false, oPoint;
layer1.off("mousedown touchstart mousemove touchmove mouseup touchend");
if(group!=undefined && group!='')
{
$this.hideAnchors(group);
}
console.log("textX: "+textX);
//after rectangle is drawn we now have to add the editablesection
$('<textarea id="text" type="text" width='+textWidth +'px height='+textHeight+'px style="font-size: 30px;font-family:Calibri;height:'+textHeight+'px;width:'+textWidth+'px;position:absolute'+';left:'+textX+'px'+';top:'+textY+'px'+';z-index:5'+';background-color:#ffcc00;"></textarea>')
.insertBefore('.kineticjs-content');
$('#text').on('blur',function()
{
console.log("textchange");
text = new Kinetic.Text( {
x: textX,
y: textY,
stroke: color,
strokeWidth: 1,
fontSize: 30,
fontFamily: 'Calibri',
clearBeforeDraw: false,
name: 'image'+layer1.getName(),
draggable: true,
height: textHeight,
width: textWidth,
text: $('#text').val()
} );
text.on( 'mouseleave dbltap', function ()
{
text=this;
} );
$('#text').remove();
layer1.add( text );
layer1.draw();
})
},drawRectangle: function ( opacity, colorFill,stroke,textColor ){rect = new Kinetic.Rect({
x: mousePos.x,
y: mousePos.y,
width: 0,
height: 0,
stroke: stroke,
strokeWidth: 4,
opacity: opacity,
clearBeforeDraw: false,
name: 'image'+layer1.getName()
});
layer1.on( "mouseup touchend", function ( e )
{
console.log("rectangle: mouseup");
console.log("width: "+rect.getWidth( ));
rect.setOpacity(opacity);
rect.setFill(colorFill);
layer1.draw();
down = false;
console.log("textColor: "+textColor)
if(textColor!=undefined)
{
textWidth=rect.getWidth( );
textHeight=rect.getHeight( );
textX = rect.getAbsolutePosition().x;
textY=rect.getAbsolutePosition().y;
$this.rectangleDrawn=true;
$this.drawText(textColor);
console.log("textdrawn ");
$this.group.remove();
}
},
