javascript - ExtJS 6 - 隐藏组件时停止事件委托(delegate)？

Question

我必须在模糊事件中隐藏相同的字段。

Extjs 6 在组件隐藏方法上调用事件委托(delegate)。事件委托(delegate)将焦点恢复到具有焦点的最后一个字段。

而且，我不想恢复焦点。有什么办法可以在隐藏 extjs 中的元素时停止事件委托(delegate)吗？

extjs 5 附带事件委托(delegate) - Delegated Events and Gestures in Ext JS 5

ExtJS 源代码中的 onHide() 方法 - 检查 revertFocus()

onHide: function(animateTarget, cb, scope) {
    var me = this,
        ghostPanel, fromSize, toBox;
    if (!me.ariaStaticRoles[me.ariaRole]) {
        me.ariaEl.dom.setAttribute('aria-hidden', true);
    }
    // Part of the Focusable mixin API.
    // If we have focus now, move focus back to whatever had it before.
    me.revertFocus(); // this revert focus making probelm
    // Default to configured animate target if none passed
    animateTarget = me.getAnimateTarget(animateTarget);
    // Need to be able to ghost the Component
    if (!me.ghost) {
        animateTarget = null;
    }
    // If we're animating, kick off an animation of the ghost down to the target
    if (animateTarget) {
        toBox = {
            x: animateTarget.getX(),
            y: animateTarget.getY(),
            width: animateTarget.dom.offsetWidth,
            height: animateTarget.dom.offsetHeight
        };
        ghostPanel = me.ghost();
        ghostPanel.el.stopAnimation();
        fromSize = me.getSize();
        ghostPanel.el.animate({
            to: toBox,
            listeners: {
                afteranimate: function() {
                    delete ghostPanel.componentLayout.lastComponentSize;
                    ghostPanel.el.hide();
                    ghostPanel.setHiddenState(true);
                    ghostPanel.el.setSize(fromSize);
                    me.afterHide(cb, scope);
                }
            }
        });
    }
    me.el.hide();
    if (!animateTarget) {
        me.afterHide(cb, scope);
    }
},

你做错了，revertFocus()是一个主要问题根源。解决方案可能是:

blurEventFunction:function(cmp){
    cmp.previousFocus = null;
    cmp.hide();
}
