I have created a SVG icon. But when I click on it. It has chances that the return object is the line segement of the SVG reather than the svg element.

Here is the UI:

Here is the evidence:

The clicked target is a POLYGON in the svg... How can this happen?

CodePudding user response：

If you are trying to access the SVG element itself, you need the Event.currentTarget property, not targetElement or srcElement. The srcElement property is equivalent to the target property, but is deprecated. The only targetElement property I can find a reference to is defined on SVGAnimationElements, not on events.

As per MDN (emphasis mine):

The currentTarget read-only property of the Event interface identifies the current target for the event, as the event traverses the DOM. It always refers to the element to which the event handler has been attached, as opposed to Event.target, which identifies the element on which the event occurred and which may be its descendant.

Take a look at this snippet:

document.querySelector('svg').addEventListener('click', (e) => {
  console.log('Target: '   e.target);
  console.log('Current target: '   e.currentTarget);
});

<svg xmlns="http://www.w3.org/2000/svg">
  <rect width="100" height="100" fill="blue"/>
  <circle cx="50" cy="50" r="35" fill="red"/>
</svg>
