可以掛載多個目錄的，建議你把錯誤貼出來，還有那個'pwd'是當(dāng)前目錄的意思，你把它換成$PWD就可以運(yùn)行了，前提是你當(dāng)前目錄下有config.yml這個文件

個人覺得可能有兩方面原因：
1：沒有設(shè)置src
2.Your player is ready，只是表明video.js做好了準(zhǔn)備，但視頻資源也許因為網(wǎng)速原因，壓根就沒加載，所以this.duration()會為NAN,你可以在loadstart監(jiān)聽中獲取這個時長

mybatis 的話這個可以實現(xiàn)的, 我之前是寫過一個類似的

表結(jié)構(gòu):

CREATE TABLE `admin_menu` (
  `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT COMMENT '自增id',
  `name` varchar(64) NOT NULL COMMENT '菜單名',
  `parent_id` bigint(3) NOT NULL DEFAULT 0 COMMENT '父菜單的id, 如果是父菜單這個值為0',
  `url` varchar(500) NOT NULL DEFAULT '' COMMENT '菜單的鏈接',
  `icon` varchar(100) NOT NULL DEFAULT '' COMMENT '圖標(biāo)',
  `menu_index` bigint(3) NOT NULL DEFAULT 0 COMMENT '展示的順序',
  `create_time` datetime NOT NULL COMMENT '創(chuàng)建時間',
  `update_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '最后更新時間',
  PRIMARY KEY (`id`),
  KEY `uq_id` (`id`),
  KEY `uq_parent_id` (`parent_id`)
) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8 COMMENT='管理后臺的菜單';

其中parentId 跟你的typeParent類似, 記錄上一級的id

AdminMenu (Model):

public class AdminMenu implements Serializable {

    private static final long serialVersionUID = -6535315608269812875L;
    private int id;
    private String name;
    private int parentId;
    private String url;
    private String icon;
    private int menuIndex;
    private Date createTime;
    private Date updateTime;
    private List<AdminMenu> subMenus;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getParentId() {
        return parentId;
    }

    public void setParentId(int parentId) {
        this.parentId = parentId;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    public String getIcon() {
        return icon;
    }

    public void setIcon(String icon) {
        this.icon = icon;
    }

    public int getMenuIndex() {
        return menuIndex;
    }

    public void setMenuIndex(int menuIndex) {
        this.menuIndex = menuIndex;
    }

    public Date getCreateTime() {
        return createTime;
    }

    public void setCreateTime(Date createTime) {
        this.createTime = createTime;
    }

    public Date getUpdateTime() {
        return updateTime;
    }

    public void setUpdateTime(Date updateTime) {
        this.updateTime = updateTime;
    }

    public List<AdminMenu> getSubMenus() {
        return subMenus;
    }

    public void setSubMenus(List<AdminMenu> subMenus) {
        this.subMenus = subMenus;
    }

    @Override
    public String toString() {
        return JsonUtil.toJson(this);
    }
}

Model的屬性跟表結(jié)構(gòu)一一對應(yīng), 最下面多了一個subMenu, 里面就是AdminMenu

下面是admin_menu.xml中的內(nèi)容

查詢SQL:

<select id="selectAllMenus" resultMap="adminMenuResult">
    SELECT
        id, name, parent_id, url, icon, menu_index, create_time, update_time
    FROM
      admin_menu
    WHERE parent_id=0
    ORDER BY menu_index
</select>

這里返回的就是adminMenuResult結(jié)果集:

<resultMap id="adminMenuResult" type="biz.menzil.admin.core.model.AdminMenu">
    <id column="id" property="id"/>
    <result column="name" property="name"/>
    <result column="parent_id" property="parentId"/>
    <result column="url" property="url"/>
    <result column="icon" property="icon"/>
    <result column="menu_index" property="menuIndex"/>
    <result column="create_time" property="createTime"/>
    <result column="update_time" property="updateTime"/>
    <association property="subMenus" column="id" select="selectSubMenus"/>
</resultMap>

其中這一行是最重要的

 <association property="subMenus" column="id" select="selectSubMenus"/>

這里用selectSubMenus來進(jìn)行了另一個查詢, 查詢的參數(shù)為id, 把查詢出來的結(jié)果放在Model中的subMenus屬性中.

selectSubMenus查詢SQL:

<select id="selectSubMenus" parameterType="long" resultMap="adminSubMenuResult">
    select
      id, name, parent_id, url, icon, menu_index, create_time, update_time
    from admin_menu
    where parent_id = #{id}
    order by menu_index
</select>

這里就是用第一層的id來查詢有沒有子菜單. 這里的#{id}就是上面那個結(jié)果集的column參數(shù).
因為我只有兩層菜單, 所以這里用了一個新的結(jié)果集,跟上面的區(qū)別就是沒有subMenus字段.

adminSubMenuResult:

<resultMap id="adminSubMenuResult" type="biz.menzil.admin.core.model.AdminMenu">
    <id column="id" property="id"/>
    <result column="name" property="name"/>
    <result column="parent_id" property="parentId"/>
    <result column="url" property="url"/>
    <result column="icon" property="icon"/>
    <result column="menu_index" property="menuIndex"/>
    <result column="create_time" property="createTime"/>
    <result column="update_time" property="updateTime"/>
</resultMap>

如果你有三,四級的話你可以一個結(jié)果集. (第一層查詢的時候用id去查詢第二層, 第二層查詢的時候用第二層的id去查詢第三層...)

下面我貼一下整個的admin_menu.xml

可以給你要view那個element 一個id，然后用scrollIntoView 這個API：
ex:

document.getElementById('chart').scrollIntoView({block: "end"});

ScrollToView

addCart的邏輯有問題。。判斷是否有商品，有就更新數(shù)量，沒有就添加商品。代碼大概如下：

// cartList的結(jié)構(gòu)是這樣:
//  [{
//      name:"橙汁",
//      count:1
//  },{
//     name:"雪碧",
//     count:1
// }]
addCart(newFood) {
    //判斷是否購物車中已經(jīng)有商品，如果有就增加數(shù)量，反之加入這個商品
    let foodIndex = this.cartList.findIndex(food => food.name == newFood);
    //foodIndex為-1表示不存在 ,要加入商品
    if (foodIndex === -1) {
        cartList.push({
            name: newFood,
            count: 1
        })
     //foodIndex存在 ,更新數(shù)據(jù)
    } else {
        cartList[foodIndex].count++
    }
}

同樣你刪除商品時，如果刪除后數(shù)量為0，就從購物車中移除。
ps: 命令規(guī)范點(diǎn)啊,carList我改成cartList了

樓主后來解決了嗎?和你遇到一樣的問題.

使用webrtc是可以的，多人的話最好從服務(wù)端考慮。

在index.html中引入，在componentDidMount（）中使用，和原生一樣

寫的很明白,把src交給webpack來處理.
html不能識別webpack中的別名
轉(zhuǎn)換成require,不但可以方便書寫路徑,還能避免相對路徑在打包后錯誤的情況
這些被require的文件還會經(jīng)過各自的loader處理,例如小圖片轉(zhuǎn)base64

1. 針對表格中提出的bug一一修復(fù)
2. 換linux系統(tǒng)

其實composer加載只是一種方式。
你可以直接下載Yii2的代碼包，然后拿出里面的 framework 出來用。

通過babel轉(zhuǎn)義的代碼看出來應(yīng)該是原型繼承

class A {
  constructor(a) {
    this.a = a;
  }
  getA() {
    console.log(a)
  }
}

class B extends A {
  constructor(b) {
    super()
    this.b = b;
  }
}

轉(zhuǎn)義后

"use strict";

var _createClass = function () { function defineProperties(target, props) { for (var i = 0; i < props.length; i++) { var descriptor = props[i]; descriptor.enumerable = descriptor.enumerable || false; descriptor.configurable = true; if ("value" in descriptor) descriptor.writable = true; Object.defineProperty(target, descriptor.key, descriptor); } } return function (Constructor, protoProps, staticProps) { if (protoProps) defineProperties(Constructor.prototype, protoProps); if (staticProps) defineProperties(Constructor, staticProps); return Constructor; }; }();

function _possibleConstructorReturn(self, call) { if (!self) { throw new ReferenceError("this hasn't been initialised - super() hasn't been called"); } return call && (typeof call === "object" || typeof call === "function") ? call : self; }

function _inherits(subClass, superClass) { if (typeof superClass !== "function" && superClass !== null) { throw new TypeError("Super expression must either be null or a function, not " + typeof superClass); } subClass.prototype = Object.create(superClass && superClass.prototype, { constructor: { value: subClass, enumerable: false, writable: true, configurable: true } }); if (superClass) Object.setPrototypeOf ? Object.setPrototypeOf(subClass, superClass) : subClass.__proto__ = superClass; }

function _classCallCheck(instance, Constructor) { if (!(instance instanceof Constructor)) { throw new TypeError("Cannot call a class as a function"); } }

var A = function () {
  function A(a) {
    _classCallCheck(this, A);

    this.a = a;
  }

  _createClass(A, [{
    key: "getA",
    value: function getA() {
      console.log(a);
    }
  }]);

  return A;
}();

var B = function (_A) {
  _inherits(B, _A);

  function B(b) {
    _classCallCheck(this, B);

    var _this = _possibleConstructorReturn(this, (B.__proto__ || Object.getPrototypeOf(B)).call(this));

    _this.b = b;
    return _this;
  }

  return B;
}(A);

new Date()是個對象
startTime.setDate(startTime.getDate() + 1)這一步操作會修改掉this.searchTime[0]的值。

你應(yīng)該粘一下整個demo的code啊

解決了 ，是密碼寫上了 ，而數(shù)據(jù)庫沒有寫上

你新建一個工程打包下是否成功，如果不成功是你環(huán)境的問題。
也有可能是cordova ionic沒有安裝成功，我以前安裝成功都需要科學(xué)上網(wǎng)的。

你先打印你的parameter，然后傳json格式數(shù)據(jù)，后臺$data = $this->input->post("data");

動手把多余的那行刪掉呀。
總不會 API 返回的數(shù)據(jù)就是這樣吧- -

document.forms[0].submit()

試一下

Ubuntu 下編譯你這個程序沒有出現(xiàn)你說的問題
