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

是的，可以删掉
