Wie man mit js die Idee der Abhängigkeitsinjektion implementiert und die Back-End-Framework-Idee auf die Front-End-Javascript-Fähigkeiten überträgt-js-Tutorial-php.cn

Wenn Sie einige Seiten erstellen, werden viele davon mithilfe von Ajax angezeigt. Offensichtlich ist dies sehr ärgerlich Teilen Sie unten die Idee, wie Sie mit js die Abhängigkeitsinjektion implementieren und die Idee des Back-End-Frameworks auf das Front-End übertragen können.

Anwendungsszenarien: Eins-zu-eins-Korrespondenz zwischen Front- und Backend, Speichern von Formularinhalten, Listenanweisungen usw.

Architektonische Ideen: Verteiler, Abhängigkeitsinjektion usw.

Grundlegende Codeanweisung:

j.extend({
 dispatcher: (function () {
  var _route = {},
   // default module
   _module = {
    // 授权
    authenticate: true,
    // 验证
    validation: true,
    // 数据转换
    dataTransform: true,
   },
   _state = {
    error: function () { }
   },
    _ajax = function () {
     j.ajax(this)
    }
  ;
  function _container() {
   // initializer.
   return _route;
  }
  function _configuration(config, _tmp_route) {

     _tmp_route += config.post.queryString;

Verwenden Sie beispielsweise die Liste:

j.dispatcher.ajax.account.getList({
 list: {
  header: ['编号', '用户名', '账户类型', '公司类型', '注册时间', '最后登录时间', '是否启用', '操作'],
  rowField: ['AccountCode', 'AccountName', 'AccountType', 'CompanyType', 'RegisterTime', 'LastActivityTime', 'IsAvailable', function (item) {
   var html = '<a href="/account/sub&#63;type=edit&id=' + item.Id + '" class="k-table-icon fa-edit mr15" title="编辑信息" ></a>'
      + '<a href="javascript:;" class="k-table-icon fa-trash" title="删除账户" onclick="operate(this,\'delete\',{ id : \'' + item.Id + '\' })"></a>'
   ;
   return html;
  }],

     return '<a href="javascript:;" onclick="operate(this,\'set\',{ id : \'' + data.Id + '\',isEnable : 1 })" class="k-table-icon c-error glyphicon glyphicon-ban-circle" title="已禁用"></a>';
   }
   else if (item.LastActivityTime) {
    var now = moment(item.LastActivityTime);
    return now.format('YYYY-MM-DD HH:mm:SS');
   }
   else if (item.RegisterTime) {

  rowClick: function () {

Rendering:

Noch einfacher ist beispielsweise das Speichern von Formularinhalten:

j.dispatcher.ajax.company.save({
Validierung: {
RulesCallBack: Funktion (Regeln) {
Rules.Name.remote = {
URL: '/handler/validation.ashx?type=cn',
        Typ: „Beitrag“, // Übermittlungsmethode
Daten: {
Firmenname: Funktion () {
                 return encodeURIComponent($("#Name").val()); //Encoded data
          }
}
}
Rules.ConfirmParssword.equalTo = "#Password";
Rules.AccountName.remote = {
URL: '/handler/validation.ashx?type=an',
        Typ: „Beitrag“, // Übermittlungsmethode
Daten: {
            AccountName: function () {
                return encodeURIComponent($("#AccountName").val()); //Encoded data
          }
}
}
},
messageCallBack: Funktion (Nachrichten) {
message.Name.remote = 'Dieses Unternehmen wurde registriert! ';
message.AccountName.remote = 'Dieser Benutzername existiert bereits! ';
messages.ConfirmParssword.equalTo = 'Zwei Passwörter sind inkonsistent';
},
Filter: ['Mobiltelefon', 'E-Mail']
},
Beitrag: {
Erfolg: Funktion () {
alarm(this.message);
        window.location ='/company/list';
}
}
});
Backend: Das Backend ist eigentlich eine sehr einfache Klasse, solange es die Implementierungsadresse des Distributors hat, wie oben: /company/save
