Answer 1

Finally i solved it out some days before. Below is code.

 initTour(lang) {
    if(lang === 'en'){

    var WELLCOME= 'Wellcome'
    var SEND_CODE = "Send code"
    var VERIFY = 'Verify'
    var CODE =  'Code'
    }

    else if(lang === 'th'){
    var WELLCOME= '惠康'
    var SEND_CODE = "发送代码"
    var VERIFY = '校验'
    var CODE =  '码'
    }

      var tourStep1Content = `
      <div class="portlet light bordered">
      <div class="portlet-title">
           <div class="caption font-green-sharp">
              <i class="icon-users font-green-sharp"></i>
              <span class="caption-subject bold uppercase">`+WELLCOME+`</span>
              <span class="caption-helper hide"></span>
            </div>
        </div>
        <div class="portlet-body">
            <h5>`+SEND_CODE+`</h5>
        </div>
     </div>`;

     var tourStep2Content = `
      <div class="mobile-verification-dialog">
      <div class="portlet light bordered">
          <div class="portlet-title">
             <div class="caption font-green-sharp">
                <i class="icon-users font-green-sharp"></i>
                <span class="caption-subject bold uppercase">`+VERIFY+`</span>
                <span class="caption-helper hide"></span>
              </div>
          </div>
          <div class="portlet-body">
              <h5 class="pull-left">`+CODE+`</h5>
              <input type="text" class="form-control" placeholder="5256458521" id="trialPhone">
              <br/>
          </div>
       </div>`;

    intro.setOptions({
      steps: [
        {
          element: '#tour_step_1',
          intro: tourStep1Content,
          position: 'left'
        },
        {
          element: '#step_two_element_id',
          intro: tourStep2Content,
          position: 'bottom'
        },

      ],
      exitOnEsc: true,
      exitOnOverlayClick: false,
      showStepNumbers: false,
      showBullets: true,
      showButtons: false
    });

  }
