Bug 192621 – messed up scope in eventHandler

• Status: RESOLVED
• Resolution: INVALID
• Component: UI Events

[g. papa]

On Chrome 71 (not on any Chrome before), if an element (select, button) has an inline onclick event with the id (of the element) specified as a parameter of the called function AND this element has children elements, the scope gets messed up and it tries to take the id of the child element.

<select id="myselect" onclick="jsDoSomething(id)"><option>1</option><option>2</option></select>

function jsDoSomething(id) {
   alert(id);
}

Chrome has forked WebKit many years ago, so new bugs that appear there are Google's own.

WebKit doesn't appear to even send a click event for selects, as I don't get any alert even after adding <script> around the code.
