在html中設置默認選項的默認值

Question

對於頁面加載，我有以下html代碼作爲默認值。但它不反映在頁面上。

<div class="col-sm-6 col-xs-12 col-md-6 col-lg-6"> 
    <label for="headoffice" class="col-sm-6 col-xs-7 col-md-4 col-lg-4 control-label">Head Office Member<sup class="text-red">*</sup></label> 
    <div class="col-sm-6 col-xs-12 col-md-8 col-lg-8">     
     <select class="multi-select" id="headoffice" name="headoffice" data-placeholder="Head Office Member"> 
      <option value=""></option> 
      <option value="No" selected="selected">No</option> 
      <option value="Yes">Yes</option> 
     </select> 
    </div> 
</div> 

Answer 1

在給定的HTML代碼，你給選擇=「選擇」爲「否」選項。你需要在「是」選項中給出如下。

<div class="col-sm-6 col-xs-12 col-md-6 col-lg-6"> 
    <label for="headoffice" class="col-sm-6 col-xs-7 col-md-4 col-lg-4 control-label">Head Office Member<sup class="text-red">*</sup></label> 
    <div class="col-sm-6 col-xs-12 col-md-8 col-lg-8">     
     <select class="multi-select" id="headoffice" name="headoffice" data-placeholder="Head Office Member"> 
      <option value=""></option> 
      <option value="No" >No</option> 
      <option value="Yes" selected="selected">Yes</option> 
     </select> 
    </div> 
</div>
