本文实例讲述了JavaScript实现点击单选按钮改变输入框中文本域内容的方法。分享给大家供大家参考。具体如下:
这里实现点击单选按钮改变输入框中文本域内容的方法,是一个JavaScript 的简单应用,可以减少用户的输入,提升用户操作易用性,它类似一个TAB选项卡一样的功能,并可以完成后提交表单,值得学习。
运行效果截图如下:
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;
}
}
