我们正在开发Office UI Fabric JS 1.2.0。问题在于具有子菜单项的上下文菜单。当您打开第二级,然后单击菜单上的任意位置时,第一级菜单关闭,第二个菜单重新对齐到页面的左上角。我们也无法在下一版织物中找到解决方案。

在覆盖ContextualHost的fabric.js中的两个方法后,问题得到解决,如下所示:

fabric.ContextualHost.prototype.disposeModal = function () {
    if (fabric.ContextualHost.hosts.length > 0) {
        window.removeEventListener("resize", this._resizeAction, false);
        document.removeEventListener("click", this._dismissAction, true);
        document.removeEventListener("keyup", this._handleKeyUpDismiss, true);
        this._container.parentNode.removeChild(this._container);
        if (this._disposalCallback) {
            this._disposalCallback();
        }
        // Dispose of all ContextualHosts
        var index = fabric.ContextualHost.hosts.indexOf(this);
        fabric.ContextualHost.hosts.splice(index, 1);

        //Following is original code removed
        //var i = ContextualHost.hosts.length;
        //while (i--) {
        //    ContextualHost.hosts[i].disposeModal();
        //    ContextualHost.hosts.splice(i, 1);
        //}
    }
};

fabric.ContextualHost.prototype._dismissAction = function (e) {

    var i = fabric.ContextualHost.hosts.length;
    while (i--) { //New added
        var currentHost = fabric.ContextualHost.hosts[i];
        if (!currentHost._container.contains(e.target) && e.target !== this._container) {
            if (currentHost._children !== undefined) {
                var isChild_1 = false;
                currentHost._children.map(function (child) {
                    if (child !== undefined) {
                        isChild_1 = child.contains(e.target);
                    }
                });
                if (!isChild_1) {
                    currentHost.disposeModal();
                }
            }
            else {
                currentHost.disposeModal();
            }
        }
    }
};

希望这个问题+答案可以帮助有人想要覆盖fabric.js的原始代码。
