Question

不确定此代码有什么问题。我一直收到以下错误：

“语法错误”

“预期的对象”：''style.cssText'为null或不是对象“

这就是我得到的：

function doSomething()
{

var textarea = document.getElementsByName("mcRemarkOld"); 
turnTextAreaIntoDiv(textarea);  
}
function turnTextAreaIntoDiv(elem)
{


    var div = document.createElement("div");     // Copy significant attributes, customize.     
    div.className = elem.className;     
    div.style.cssText = elem.style.cssText; <<<<<<---''style.cssText' is null or not an object    
    div.id = elem.id;     
    div.name = elem.name;  <<----SYNTAX ERROR HERE
    div.innerHTML = elem.innerHTML; //`<a>` turns in  &lt;a&gt;    
    elem.parentNode.replaceChild(div, elem); 
    }



 </script>

   <body onload="javascript:doSomething()">


      <TEXTAREA class="textarea_readonly" readonly="readonly" name="mcRemarkOld" rows="7"  cols="100" scrolling="auto">        <c:forEach var="mcbean" items="${form.mcRemarks}">---  ${mcbean.auditable.createdBy.firstName} ${mcbean.auditable.createdBy.lastName}, <fmt:formatDate value="${mcbean.auditable.createdDate}" pattern="${date_time_pattern}" />

  ${mcbean.remark} ---  <a href="show.view_hotparts_guidelines?id=${mcbean.id}">TEST!!!!!!</a>  

  </c:forEach></TEXTAREA><br/>

Answer 1

变量是一个元素数组

var textarea = document.getElementsByName("mcRemarkOld");

尝试使用：

var textarea = document.getElementsByName("mcRemarkOld")[0];

或

var textarea = document.getElementByName("mcRemarkOld");

Javascript“语法错误”/“预期的对象”/''style.cssText'为null或不是对象“
