[英]How to get targeted element's attribute value in fabric.js
(function() {
var canvas = this.__canvas = new fabric.Canvas('c');
fabric.Object.prototype.transparentCorners = false;
canvas.on({
'object:selected': function(e) {
e.target.opacity = 0.5;
//find which object is selected
console.log(e.target);
console.log(e.target.get('type'));
//How to get targeted element attribute value
//??????????????
},
'object:modified': function(e) {
e.target.opacity = 1;
}
});
fabric.Image.fromURL('img/shoes-hills.png', function(oImg1) {
// scale image down, and flip it, before adding it onto canvas
oImg1.perPixelTargetFind = true;
canvas.add(oImg1);
});
})();
如何在fabric.js中獲取目標元素的屬性值。 在這里,我得到目標元素的類型,但是我想要該圖像元素的屬性值(圖像源),以標識在此畫布中選擇了哪個圖像元素。
這是解決方案的小提琴: https : //jsfiddle.net/jimedelstein/yb9yf0vr/
只需調用e.target.getSrc()
您可能需要先進行類型檢查(並且您已經知道如何按照現有代碼進行檢查。)
希望那是您想要的!
您也可以嘗試以下方法:
//instead of e.target you can get the selected object with findTarget()
var targetObj= this.findTarget();
//now that we have the selected object you can get the src property of the _element property.
console.log(targetObj._element.src);//1st way
console.log(targetObj._element.currentSrc);//2nd way
console.log(targetObj.getSrc());//3rd way
希望有幫助,祝你好運。
