解决方案 »

  1.   

     document.getElementById("文本框的id").value
     document.getElementsByName("文本框的name").value
     document.getElementsByTagName("input") 取出来一个数组
      

  2.   

    楼上的都可以啊，如果要传参，
    request.getParamenter()也可以啊
      

  3.   


    这个取不到呀
    这个是js写出来的
    if(document.all){ 
    document.write(' <textarea name="sourceEditor" ID="sourceEditor" style="height:246px;width:100%;marign:0;padding:0;font:normal 12px Tahoma;display:none;word-break:break-all;border:none;background:#fff;" onpropertychange="try{parent.SourceEditor_PropertyChange();}catch(e){}"> </textarea>'); 
    }else{ 
    document.write(' <textarea name="sourceEditor" ID="sourceEditor" style="height:246px;width:100%;marign:0;padding:0;font:normal 12px Tahoma;display:none;word-break:break-all;border:none;background:#fff;" onpropertychange="try{parent.SourceEditor_PropertyChange();}catch(e){}"> </textarea>'); 
    } 
    就在这块   把这块删了就没有了输入框  ， 可是取哪个值到取不到
      

  4.   

    你这段代码是在页面写一个隐藏的文本域，本身没有值，如果你使用document.getElementById("sourceEditor").value时取出的是一个空，如果你改成这个样子：
    <textarea name="sourceEditor" ID="sourceEditor" style="height:246px;width:100%;marign:0;padding:0;font:normal 12px Tahoma;display:none;word-break:break-all;border:none;background:#fff;" onpropertychange="try{parent.SourceEditor_PropertyChange();}catch(e){}">aaaa</textarea>就可以取到值了。
      

  5.   

    用隐藏域，测试如下
    <HTML>
     <HEAD>
      <TITLE> New Document </TITLE>
      <META NAME="Generator" CONTENT="EditPlus">
      <META NAME="Author" CONTENT="">
      <META NAME="Keywords" CONTENT="">
      <META NAME="Description" CONTENT="">
     </HEAD>
    <script type="text/javascript">
     document.write('<textarea name="sourceEditor" ID="sourceEditor"  onfocus="document.getElementById(\'textareavalue\').value=this.value;">aaa </textarea>'); 
    </script>
     <BODY>
     <input type="hidden" id="textareavalue" value="1">
     </BODY>
    </HTML>
