1.簡歷中的具體項目可以做更詳盡的描述,例如在xx項目中采用了什么技術(shù),寫得越詳細(xì)越好。

2.簡歷的模板,用官方的就好。把你的技能點(diǎn)突出即可,不用把過多的心思花在簡歷的排版上。

3.招聘平臺那么多,為何第二次還是投在了拉鉤上?先廣撒網(wǎng)再說吧。

熱替換還需要其他的東西支持,如果是用vue的話vue-loader,react需要react-hot-loader

嗯,命令可以直接執(zhí)行的……

幫你把sh下下來了,你存下來試試看,我就估計你git clone的時候也會卡住。哈哈,到時候再找我吧。

墨染殤 回答

你的代碼省略掉了關(guān)鍵部分,這個刪除應(yīng)該有網(wǎng)絡(luò)異步請求。頁面卸載了,執(zhí)行setState當(dāng)然報錯

卟乖 回答

中小項目vue,大點(diǎn)的react,vue小巧靈活,react厚重,但是代碼組織相對較為規(guī)范,維護(hù)方便,看你自己需求決定了,我個人覺得,react+redux最好是大型應(yīng)用使用,不然體驗不到redux帶來的快感,反而是個累贅。

替身 回答

我的建議是后臺提供新的接口,返回所有項目的同時也返回其統(tǒng)計數(shù)據(jù)。

薔薇花 回答

原型污染,一般不改變默認(rèn)方法執(zhí)行的話,危險不是太大
如果改變了默認(rèn)方法,如果還有其他庫,則可能出現(xiàn)未知問題。

這個跟模板沒啥關(guān)系,我感覺是不是外部的webseriver配置有問題

自己嘗試解決了,雖然不知道原因:

先啟動apollo
再啟動Node Server就沒問題了

在QDialog類下 覆蓋 paintevent就可以了。

def paintevent(self, event):
    qp = QPainter()
    qp.begin(self)
    qp.setBrush(QColor(0,0,0))
    qp.drawRect(50,50,50,50)
    qp.end()
我不懂 回答

第一次知道 padding 可以這么用,厲害厲害。

Abox 的 height 是 190px 沒錯啊,box 的 height 才為 0。

line-height 適合處理單行文字的垂直居中,多行就不行了。

題主想用絕對定位來垂直居中,但是需要 Abox 有具體的 height 且與文本區(qū)域的 height 一樣。

然后這種情況我覺得可以給文本區(qū)域加個包含塊來解決。

利用表格樣式:

<div class="box">
  <div id="Abox" class="Abox">
    <table>
      <tbody>
        <tr>
          <td>A元素垂直居中 A元素距離屏幕左右各邊各10px A元素里的文字font—size:20px,水平垂直居中 A元素的高度始終是A元素寬度的50%</td>
        </tr>
      </tbody>
    </table>
  </div>
</div>
table {
  height: 100%;
}

利用變換 transform:

<div class="box">
  <div id="Abox" class="Abox">
    <div class="inner">A元素垂直居中 A元素距離屏幕左右各邊各10px A元素里的文字font—size:20px,水平垂直居中 A元素的高度始終是A元素寬度的50%</div>
  </div>
</div>
.inner {
  position: absolute;
  top: 50%;
  transform: translateY(-50%);
}
