// first case
$('canvas').drawRect({
layer: true,
data: { w: 300 },
fillStyle: '#585',
x: 100, y: 100,
width: 100, height: 50
});
alert($('canvas').getLayer(0).data.w);
I can get the data out of the layer.
// second case
$('canvas').drawRect({
layer: true,
data: { w: 300 },
fillStyle: '#585',
x: 100, y: 100,
width: $('canvas').getLayer(0).data.w, height: 50
});
I can't get the data within the layer itself.
An easy and practical solution would be to specify your data object beforehand so that it is accessible within the scope of your drawRect() call:
var rectData = { w: 300 };
$('canvas').drawRect({
layer: true,
data: rectData,
fillStyle: '#585',
x: 100, y: 100,
width: rectData.w, height: 50
});
