function JM_you(ob) {

function createForm(textN, number) {
data = "";
inter = "'";
if (number < 11 && number > -1) {
for (i = 1; i <= number; i++) {
if (i < 10) spaces = " ";
else spaces = " ";
data = data + " <input name=" + textN + i + " type=text value='' size='30' maxlength='100'>"

}
if (document.layers) {
document.layers.cust.document.write(data);
document.layers.cust.document.close();
}
else {
if (document.all) {
cust.innerHTML = data;
}
}
}
else {
window.alert("请不要超过10张图片.");
}
}
</script>
</head>
<body>
<form name="prodtable" action="">
<input type="radio" name="more_pic" checked value="0" onclick="JM_wu(s1)">无
<input type="radio" name="more_pic" value="1" onclick="JM_you(s1)">有 <span id="s1" style="display:none">
<input name="more" type="text" value='1' size='5' maxlength='2'>
<input type="button" value="张大图" onclick="createForm('more',document.prodtable.more.value);">
<span id="cust" style="position: relative;"></span></span>
</form>
</body>
