                        </tr>
                       
                    </table> <input id="hd_CompanyID" type="hidden" runat="server" />这是前台控件代码我想取  CheckBox 里面的 TEXT  并且以“，”拼接起来。如哪个被选中 就是 空中运输伤害，航空港伤害，..，这样的形式。
这是我写的拿不出来。
function check() 
  {
   var s="";
   var inputs=document.getElementsByTagName("CheckBox ");
   for(var i=0;i<inputs.length;i++){
    if(inputs[i].type=="checkbox"){
     if(inputs[i].checked){
         s+=inputs[i].Text+",";
         document.getElementById("hd_CompanyID").value=s;
     }
    }
   }
}
谁能给写下这段 取值JS。 大学刚毕业工作，没学过JS，学习中希望大家不要见笑。

Answer 1

getElementsByTagName("CheckBox "); ==>getElementsByTagName("INPUT
"); 

Answer 2

另:checkbox是没有Text的.改成
  s+=inputs[i].nextSibling.innerHTML
+","; 

Answer 3

var inputs=getElementsByTagName("CheckBox "); 
s+=inputs[i].nextSibling.innerHTML +","; 

Answer 4

var chbs=getElementsByTagName("INPUT");
 

Answer 5

正解，checkBox生成的HTML代码是Input开头的.......

Answer 6

function FinalCheck()
 {
 var chk=new Array();
chk=document.getElementsByName("");
 var p=document.getElementById("");
var l=chk.length;
for(var i=0;i<l;i++)
{        
if(chk[i].checked)
{            
if(Clist.value=="")
{
p.value=chk[i].value;
}
else
{
p.value=p.value+"|"+chk[i].value;
}
}
}
}

Answer 7

function check() 
  { 
  var s=""; 
  var inputs=document.getElementsByTagName("input");  //是input不是checkbox
  for(var i=0;i <inputs.length;i++){ 
    if(inputs[i].type=="checkbox"){ 
    if(inputs[i].checked){ 
        s+=inputs[i].innerHTML+","; 
            } 
    } 
  } 
  
document.getElementById("hd_CompanyID").value=s; } 

Answer 8

var s=""; 
  var inputs=document.getElementsByTagName("input"); 
    for(var i=0;i <inputs.length;i++) 
    {         
        if(inputs[i].type = "checkbox") 
        { 
            
            if(inputs[i].checked) 
            {
             }          
        } 
    }

Answer 9

去掉,号在最后一句之前if(s!="")
{
 s = s.substring(0,s.length-1);}
