Javascript根据浏览器的ID隐藏元素
我正在尝试向所有浏览器显示一条消息，并通过 javascript 将其删除（如果支持）。目前隐藏它的唯一方法是单击隐藏按钮。它不会在我的 if 语句中运行。
<html>
<head>
<script type="text/javascript">
var browser=navigator.appCodeName + navigator.appName;
function hideStuff(id) {
document.getElementById(id).style.display = 'none';
}
function supportedBrowser() {
if (browser == "MozillaNetscape")
{
document.write("Browser is Mozilla Netscape");
}
else if (browser == "MozillaOpera")
{
document.write("Browser is Mozilla Opera");
hideStuff('browserMessage');
}
else
{
alert("Please upgrade your browser.");
}
}
//-->
</script>
</head>
<body>
<a href="#" onclick="hideStuff('browserMessage'); return false;">Hide</a>
<br><br>
<p id="browserMessage" style="display: inline;">Please use a supported browser.</p>
</body>
</html>
根据“bluevoodoo1”进行更改
<html>
<head>
<script type="text/javascript">
var browser=navigator.appCodeName + navigator.appName;
function hideStuff(id) {
document.getElementById(id).style.display = 'none';
}
function supportedBrowser() {
if (browser == "MozillaNetscape")
{
document.write("Browser is Mozilla Netscape");
}
else if (browser == "MozillaOpera")
{
document.write("Browser is Mozilla Opera");
//hideStuff('browserMessage');
}
else
{
alert("Please upgrade your browser.");
}
}
function init() {
supportedBrowser();
//etc
}
window.onload = supportedBrowser;
//-->
</script>
</head>
<body>
<a href="#" onclick="hideStuff('browserMessage'); return false;">Hide</a>
<br><br>
<p id="browserMessage" style="display: inline;">Please use a supported browser.</p>
<p>This text shoudld not be hidden.</p>
</body>
</html>
有人知道我做错了什么吗？
I am trying to show a message to all browsers and remove it though javascript if it is supported. Currently the only way it will be hidden is if I click a hide button. It won't run in my if statement.
<html>
<head>
<script type="text/javascript">
var browser=navigator.appCodeName + navigator.appName;
function hideStuff(id) {
document.getElementById(id).style.display = 'none';
}
function supportedBrowser() {
if (browser == "MozillaNetscape")
{
document.write("Browser is Mozilla Netscape");
}
else if (browser == "MozillaOpera")
{
document.write("Browser is Mozilla Opera");
hideStuff('browserMessage');
}
else
{
alert("Please upgrade your browser.");
}
}
//-->
</script>
</head>
<body>
<a href="#" onclick="hideStuff('browserMessage'); return false;">Hide</a>
<br><br>
<p id="browserMessage" style="display: inline;">Please use a supported browser.</p>
</body>
</html>
Changed as according to "bluevoodoo1"
<html>
<head>
<script type="text/javascript">
var browser=navigator.appCodeName + navigator.appName;
function hideStuff(id) {
document.getElementById(id).style.display = 'none';
}
function supportedBrowser() {
if (browser == "MozillaNetscape")
{
document.write("Browser is Mozilla Netscape");
}
else if (browser == "MozillaOpera")
{
document.write("Browser is Mozilla Opera");
//hideStuff('browserMessage');
}
else
{
alert("Please upgrade your browser.");
}
}
function init() {
supportedBrowser();
//etc
}
window.onload = supportedBrowser;
//-->
</script>
</head>
<body>
<a href="#" onclick="hideStuff('browserMessage'); return false;">Hide</a>
<br><br>
<p id="browserMessage" style="display: inline;">Please use a supported browser.</p>
<p>This text shoudld not be hidden.</p>
</body>
</html>
Does anyone know what I am doing wrong?

你可能需要使用 window.onload 处理程序...（jquery 的“document.ready”可能是首选，但我在下面使用一些本机 javascript）
you might need use the window.onload handler... (jquery's "document.ready" is probably preferred, but I'm using some native javascript below)
