<script type= "text/javascript ">
function gett(){
var trs=document.getElementById( "tabt ").rows;
var aVal=new Array();
for(var i=0;i <trs.length;i++){
var ts=trs[i].getElementsByTagName( "input ");
if(ts[0].checked==true){
var texts=new Array();
for(var n=1;n <ts.length;n++){
texts.push(ts[n].value);
}
aVal.push(ts[0].name+ "：= "+texts.join( "||| "));
}
}
alert(aVal.join( "\n "));
}
</script>
<table id= "tabt ">
<tr> <td> <input type= "checkbox " name= "a "> <input type= "text "> <input type= "text "> <input type= "text "> </td> </tr>
<tr> <td> <input type= "checkbox " name= "b "> <input type= "text "> <input type= "text "> <input type= "text "> </td> </tr>

<input type= "button " onclick= "gett() " value= "得到值 ">
