具体代码如下:

<html>

<head>

<title>JavaScript点击单选框改变输入框内容</title>

</head>

<body>

<script language=JavaScript>

var defaultValue = ""

function Changes() {

var defaultValue = "changed";

}

ie = document.all?1:0

ns4 = document.layers?1:0

var c = 1

function hideIt(id) {

if (ie) {

document.all[id].style.zIndex = c--;

document.all[id].style.visibility = "hidden";

document.all['hider'].style.visibility = "visible";

}

else if (ns4) {

document.layers[cat].layers[id].zIndex = c--;

document.layers[cat].layers[id].visibility = "hide";

document.layers[cat].layers['hider'].visibility = "show";

}

}

function showIt(id) {

if (ie) {

document.all[id].style.zIndex = c++;

document.all[id].style.visibility = "visible";

}

else if (ns4) {

document.layers[cat].layers[id].zIndex = c++;

document.layers[cat].layers[id].visibility = "show";

}

else {

document.getElementById(id).style.zIndex = c++;

document.getElementById(id).style.visibility = "visible";

}

}

function imgLbl(tab) {

premier = frmWc.elements[tab - 1];

if (premier.checked == 1) {

premier.checked = 0;

} else {

premier.checked = 1;

}

}
