Question

考虑到这是HTML代码，

＆＃13;

function changeColor(){
       var selectedColor = document.getElementById("selectColor").value;
       if(selectedColor != "selectTheColor"){
          document.bgColor = selectedColor;
          document.cookie = "color="+selectedColor+";expires=Fri, 2 Mar 2018 02:00:00 UTC";
          var splited = document.cookie.split("="); // codes here not working
          alert(splited[1]);
       }
    }

＆＃13;

<select value="bgColor" id="selectColor" onchange="changeColor();">
          <option value="selectTheColor">Select color</option>
          <option value="black">Black</option>
          <option value="blue">Blue</option>
          <option value="red">Red</option>
    </select>

＆＃13;

为什么代码不能解析？

Answer 1

这种方式不支持在一行以上分配字符串（使用''，你必须使用``代替）。请改为：

function changeColor(){
   var selectedColor = document.getElementById("selectColor").value;
   if(selectedColor != "selectTheColor"){
      document.bgColor = selectedColor;
      var test = "color="+selectedColor+`;expires=Fri, 2 Mar 2018 
      02:00:00 UTC`;
      var splited = test.split("="); // codes here not working
      alert(splited[1]);
   }
}

<select value="bgColor" id="selectColor" onchange="changeColor();">
      <option value="selectTheColor">Select color</option>
      <option value="black">Black</option>
      <option value="blue">Blue</option>
      <option value="red">Red</option>
</select>

分裂的cookie串不起作用
