Question

I already read this, but i still can’t make it work. ‘e’ just don’t have property ‘returnValue’. What’s wrong?

Html

<img id="vtkPicImg" style="display: none;" jQuery17102915111663214694="47"/>

Here js code:

var vtk = $("#vtkPicImg");

vtk.bind('mousedown', function(e) {
    e.preventDefault ? e.preventDefault() : e.returnValue = false;
    vtk_mouseDown(e);
    return false;
});

Update

Regarding your updated question, there is no “default” behavior when clicking an <img> element, so naturally there’s nothing to prevent.

---

Since you’re using jQuery, all you need is…

e.preventDefault();

Cross browser issues are fixed.

Your trouble is probably that you’re doing it on a mousedown event with an element that has no default behavior for mousedown.

---

To prevent whatever default behavior you’re trying to prevent, you’ll probably need to do it using the click event.

var vtk = $("#vtkPic");

vtk.bind('click', function(e) {
     e.preventDefault();

})
   .bind('mousedown', function(e) {
        vtk_mouseDown(e);
    });
