lose focus after inputing one key in newitem input box with firefox browser about preact HOT 8 CLOSED

add one new issue:
In Firefox, edit function can not work well. After appending some chars in editing status and pressing enter key, rendered result is the original value instead of new value.

Hi @steven88888 - apologies for the delayed reply. Definitely a bug and something I'm looking into. It seems like something is invalidating the root node of the todomvc example, blurring the input. I'll keep you posted on progress.

Just removed from app/index.js

<Router onChange={this.handleRoute}><Noop path="/" /></Router>

and all works fine.

@c58 Ah yeah, that makes sense. That was a hack at best anyway, I should have just parsed the URL without pulling in preact-router.

I think i found the problem. Router's nodeType is 3 (text dom node), but it is not a "string" vnode, as expected in isSameNodeType.

// attempt to pluck a node of the same type from the existing children
            if (!child && min<childrenLen) {
                for (let j=min; j<childrenLen; j++) {
                    let c = children[j];
                    if (c && isSameNodeType(c, vchild)) {
                        child = c;
                        children[j] = null;
                        if (j===childrenLen-1) childrenLen--;
                        if (j===min+1) min++;
                        break;
                    }
                }
            }

In this case every update will make a redraw from the root, because new children is never equals to previous children.

@c58 Hmm - this must be using the old version of preact-router that was not using High Order components to render children? The package.json for preact-todomvc has [email protected] though, which was using High Order (switchover was 1.0.0).

How are you checking the nodeType value of Router?

Also heads up: the child diffing algo is a bit different in 4.0. Still working on getting my branch pushed!

How are you checking the nodeType value of Router?

Just debug in a browser :) Open page, write some letters in input, set a pointer in a line:

if (c && isSameNodeType(c, vchild)) {

and write some letter in an input. And here we are, "c" is a dom node of a Router, vchild is a Router object. c.nodeType is 3.

In my research im using preact 3.4.0 and router 1.2.3

from preact.

If change isSameNodeType to:

  function isSameNodeType(node, vnode) {
    if (isString(vnode)) return node.nodeType === 3;
    if (isFunctionalComponent(vnode)) return true;
    var nodeName = vnode.nodeName;
    if (isFunction(nodeName)) return node._componentConstructor === nodeName;
    return toLowerCase(node.nodeName) === nodeName;
  }

then issues will be fixed
