javascript中动态生成了javascript，如何把动态生成的javascript原有的javascript中？？

<script>
function show()
{
var text = "<script> function show() { ";
for(var i=0; i<TableGoods.rows.length; i++)
{
text = text + "if(document.forms(\"form1\").tr"+i
+ ".checked==true){ document.getElementById(\"td"+i
+ "\").style.display = \"\"; } else{ document.getElementById(\"td"+i
+ "\").style.display = \"none\"; } ";
}

text = text + " } <\/script>";
alert(text);

document.write(text); //这里出问题了，我应该怎么写才会得到我下面的javascript，请告诉指点啊！！

}
</script>


我想要的脚本如下：


<script>
function show()
{
if(document.forms("form1").tr0.checked==true){
document.getElementById("td0").style.display = ""; }
else{
document.getElementById("td0").style.display = "none"; }

if(document.forms("form1").tr1.checked==true){
document.getElementById("td1").style.display = ""; }
else{
document.getElementById("td1").style.display = "none"; }

if(document.forms("form1").tr2.checked==true){
document.getElementById("td2").style.display = ""; }
else{
document.getElementById("td2").style.display = "none"; }

if(document.forms("form1").tr3.checked==true){
document.getElementById("td3").style.display = ""; }
else{
document.getElementById("td3").style.display = "none"; }

.........
}
