The basic approach is to toggle the CSS display with Javascript. 基本方法是使用Javascript切换CSS显示。 This is the break down of the below code: 这是下面的代码的分解:
window.onload
part does. 这就是window.onload
部分的工作。 document.getElementById
用document.getElementById
标识链接和框 Toggle the display with style.display
. 使用style.display
切换显示。
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>Onclick Example</title> <script type="text/javascript"> window.onload = function(){ var link = document.getElementById('rulink'); var box = document.getElementById('box'); var close = document.getElementById('close'); link.onclick = function(){ box.style.display = 'block' } close.onclick = function(){ box.style.display = 'none'; } } </script> <style> div{ display:none; background:#f00; width:100px; } </style> </head> <body> <a href="javascript:void(0)" id="rulink">report user</a> <div id="box"> <ul> <li>abc</li> <li>def</li> </ul> <a href="javascript:void(0)" id="close">Close</a> </div> </body>
查看onclick
事件。
I would look into jquery, it makes javascript much easier. 我会研究jquery,它使javascript更加容易。 Using jquery you could perform that using one line of code such as: 使用jquery,您可以使用一行代码执行该操作,例如:
$('.<link class>').click(function(){$('.<list class>').show()});
You can do it this way, but it's pretty crude: 您可以用这种方式来做,但是很简单:
<a href="" onclick="document.getElementById('something').style.display='inherit';return false" >###</a>
<input style="display:none" type="text" id="something" />
That's the "hard way", but understanding how it works is important. 那是“艰难的道路”,但是了解其工作方式很重要。
It is worth it to use a JavaScript framework. 使用JavaScript框架是值得的。 Jquery is the most popular and it can seriously make doing any UI work WAY easier. jQuery是最流行的,它可以使所有UI工作变得更容易。
You can shorten that onclick to: 您可以将onclick缩短为:
$('#something').show()
<script>
document.getElementById("showHide").onclick = function() {
var theDiv = document.getElementById("foo");
if(theDiv.style.display == 'none') {
theDiv.style.display = 'block';
this.innerHTML = 'Hide';
} else {
theDiv.style.display = 'none';
this.innerHTML = 'Show';
}
}
</script>
<span id="showHide">Show</span>
<div id="foo" style="display:none">
<form method="post">
<h3>Here are some reasons</h3>
Blah: <input type="checkbox"/><br />
Blah: <input type="checkbox"/><br />
Blah: <input type="checkbox"/><br />
<input type="submit" value="submit" />
</form>
</div>
