$translate 的用法

translate 的用法
1.在html页面：文本的翻译
<h1 translate>hello world</h1>
<h1 translate = 'hello world '></h1>
<h1> 'hello world '|translate </h1>

2.
placeholder= {{var|translate}}
aria-label={{var|translate}}
tooltip = {{var|translate}}
ng-bind= {{var|translate}}
ng-bind= {{key|translate}}

<p translate = 'key'  translate-values= ' { index:' {{var}}'}'
--json
key:".....{{index}}"

3.$translate.use();
define(function (require) {
  return function SavedObjectFactory(es, kbnIndex, Promise, Private, Notifier, safeConfirm, indexPatterns,$translate) {
    var angular = require('angular');

      //luochunxiang@eisoo.com
      var message ;
      var lang = $translate.use();
      if(lang === 'zh-cn'){
        message = '你确定你想要覆盖 '
      }else if(lang === 'zh-tw'){
        message = '你確定你想要覆蓋  '
      }else{
        message = 'Are you sure you want to overwrite '
      }
$
4.$translate.instant（key）

var a = $translate.instant("Are you sure you want to delete the selected");
var b = $translate.instant("Are you sure you want to delete the selected");
var aaa = `trgutyr ${a}${currentTab.title}${b}`;
'rtguiyi'
var bbb = aaa;

---.js
       var option = {
          "Seconds": $translate.instant("Seconds ago"),
          "Minutes":$translate.instant("Minutes ago"),
          "Hours": $translate.instant("Hours ago"),
          "Days": $translate.instant("Days ago"),
          "Weeks": $translate.instant("Weeks ago"),
          "Months": $translate.instant("Months ago"),
          "Years": $translate.instant("Years ago")
        };
        $scope.relativeOptions = [
          {text: option.Seconds, value: 's'},
          {text: option.Hours, value: 'm'},
          {text: option.Days, value: 'h'},
          {text: option.Days, value: 'd'},
          {text: option.Weeks, value: 'w'},
          {text: option.Months, value: 'M'},
          {text: option.Years, value: 'y'},
        ];

---.html
                  <div class="form-group">
                    <select
                      ng-model="relative.unit"
                      ng-options="opt.value as opt.text for opt in relativeOptions"
                      translate-values
                      ng-change="formatRelative()"
                      class="form-control col-xs-2">
                    </select>
                  </div>

5直接使用window.localStorage.lang;
    //luochunxiang@eisoo.com
    var message ;
    var lang =  window.localStorage.lang;
    if(lang === 'en-us'){
      message = 'MMMM Do YYYY, HH:mm:ss.SSS'
    }else if(lang === 'zh-tw'){
      message = 'YYYY年MM月DD日, HH:mm:ss.SSS'
    }else{
      message = 'YYYY年MM月DD日, HH:mm:ss.SSS'
    }

6  ng-show = "lang === 'en-us'"
    <div ng-show = "lang === 'en-us'">
      <saved-object-finder
              title="Saved Searches"
              type="searches"
              make-url="step2WithSearchUrl">
      </saved-object-finder>
    </div>
    <div ng-show = "lang === 'zh-tw'">
      <saved-object-finder
              title="已存搜索"
              type="searches"
              make-url="step2WithSearchUrl">
      </saved-object-finder>
    </div>
    <div ng-show = "lang === 'zh-cn'">
      <saved-object-finder
              title="已存搜索"
              type="searches"
              make-url="step2WithSearchUrl">
      </saved-object-finder>
    </div>

    <div ng-if="aggParam.name">
      <span><label>{{ aggParam.name | translate }}</span> <span translate>Pattern</span></label>
    </div>
    <div ng-if="label">
      <label>{{ label  | translate }} <span translate>Pattern</span></label>
    </div>

<!--     <label>{{ aggParam.name | label }} <span translate>Pattern</span></label> -->
