jquery.ztree.core.js line:806 x = false冗余？

从代码上看好像确实没有什么用定义x这个变量 proxy: function (e) { var setting = data.getSetting(e.data.treeId); if (!tools.uCanDo(setting, e)) return true; var results = event.doProxy(e), r = true, x = false; for (var i = 0, l = results.length; i < l; i++) { var proxyResult = results[i]; if (proxyResult.nodeEventCallback) { x = true; r = proxyResult.nodeEventCallback.apply(proxyResult, [e, proxyResult.node]) && r; } if (proxyResult.treeEventCallback) { x = true; r = proxyResult.treeEventCallback.apply(proxyResult, [e, proxyResult.node]) && r; } } return r; } x 变量全程都没有使用，是不是可以删掉
