因为我不会c++
我是学Java的谁能帮我看看这个代码怎么不执行
function getByclass(clsName,parent){
var oParent=parent?document.getElementById(parent):document,
elements=oParent.getElementsByTagName('*');
for(var i=0;i&elements.i++){
if(elements[i].className==clsName){
eles.push(elements[i]);
window.onload=
function drag(){
var oTiltle=getByclass('login_logo_webqq','loginPanel')[0];
oTiltle.onmousedown=fnD
function fnDown(event){
event=event || window.
var oDrag=document.getElementById('loginPanel'),
//光标按下时光标和面板之间的距离
disX=event.clientX-oDrag.offsetLeft,
disY=event.clientY-oDrag.offsetT
document.onmousmove=function(event){
event=event || window.
fnMove(event,disX,disY);
function fnMove(e,posX,posY){
var oDrag=document.getElementById('loginPanel'),
l=e.clientX-posX,
t=e.clientY-posY;
oDrag.style.left=l+'px';
oDrag.style.top=t+'px';

学习的flask博客程序，after_request()函数貌似有问题，求解答
@app.after_request() ===〉 @app.after_request

谢啦，好低级的错误
你有没有在 BAE 上试着部署呢？我在部署的时候出现了问题……
#configuration DATABASE='/tmp/flaskr.db'
DEBUG=True
SECRET_KEY='development key'

这里是不是用
app.config['xxxx'] 这种方式更好？扫二维码下载作业帮

bust 胸围waist 腰围hips 臀围单位是英寸，一英寸威2.54厘米，然后你自己算吧
SIZE 1/2-11/12的是童装尺码 1/2是6-24个月穿的 以此类推 其他像上面那位兄弟说的 一英寸等于2.54cm 然后再把厘米/33.3333333就是市尺单位了
