配置這樣寫(xiě)應(yīng)該是沒(méi)問(wèn)題,看看你ajax請(qǐng)求的連接是不是錯(cuò)了

css里面加一個(gè)font-size: 40px;

<style type="text/css">
    .icon {
        width: 1em; height: 1em;
        vertical-align: -0.15em;
        fill: currentColor;
        overflow: hidden;
        **font-size: 40px;**
    }
</style>

是不是錨點(diǎn)呢?考慮下使用錨點(diǎn)定位試試呢

step 1: 畫(huà)個(gè)圓。

step 2: 劃分獎(jiǎng)項(xiàng)區(qū)域,如0~60°一等獎(jiǎng)....

step 3: 在0~360隨機(jī)生成一個(gè)角度(此時(shí)獎(jiǎng)項(xiàng)已生成),

step 4: 設(shè)置默認(rèn)快速旋轉(zhuǎn)n圈,結(jié)束之后速度遞減旋轉(zhuǎn)到生成角度位置。

只是提供一個(gè)思路

/a/@href 好像是這么寫(xiě)的

笨小蛋 回答

參照:Index Types Per Storage Engine, 這個(gè)存儲(chǔ)引擎有關(guān)系,InnoDB和MyISAM只支持BTREE,因此默認(rèn)均是BTree,MEMORY和HEAP支持Hash和Btree,如無(wú)明確聲明,則默認(rèn)索引均是hash(包括主鍵)。

命多硬 回答

先不說(shuō)做法合不合理,先說(shuō)大致解法吧。
點(diǎn)擊切換-獲取當(dāng)前播放進(jìn)度a-替換src-播放-跳轉(zhuǎn)進(jìn)度至a
主流的做法是使用文件流blob代替MP4

Update:

如果等于這個(gè),程序會(huì)更慢,我覺(jué)得應(yīng)該等同于a == b || a > b才對(duì)。

That's not true. Your platform will not split >= into == and >. The implementation varies from platform to platform and compiler to compiler. From Assembly(https://godbolt.org/g/6MCvQq):

if (a >= b)

=>

  mov eax, dword ptr [rbp - 12]
  cmp eax, dword ptr [rbp - 16]
  jl .LBB0_4

   if (a > b)

=>

   cmp r8d, dword ptr [rbp - 16]
   mov dword ptr [rbp - 20], eax # 4-byte Spill
   jle .LBB0_2

Both have 3 instructions.

Also take a look at these awesome answers: https://stackoverflow.com/que...


Both are true. || is logic or operator in some languages(which belongs to logic operators). I assume you have limited the symbols to c++(because you didn't use the more general terms like logic or and logic and. In standard ml, logic or is expressed as or, same for logic and)

In c++, please correct = to ==. The former is a Direct assignment operator, while the latter is Equal to operator. If a satisfy the condition, the b will not be used. For example:

if (a && b)

is equal to

if (a)
    if(b)
        ...
        

BTW, in some algorithms, if you want to judge if a node exists (like arr[x][y] == 'x'), it should be put in b rather than a. Because sometimes a is used to filter out-of-range conditions.

已解決 python版本從2.7.10升級(jí)到2.7.13即可

冷咖啡 回答

1.前端不進(jìn)行跨域,叫后臺(tái)進(jìn)行修改
2.使用JSONP 前端進(jìn)行跨域 -- 此時(shí)也需要后端進(jìn)行配合
jsonP方式可參考:https://www.cnblogs.com/xcxc/...
