我在哪里可以访问生产服务器上的ASP.NET配置？(Where can I access the ASP.NET Configuration on a production server?)

 粗略地说，您需要单击以触发一些更改相关目标的不透明度的JavaScript代码。 一个简单的例子是这样的： 
 
<style>
.topping {
    opacity: 0;
}
</style>
<div onclick='changeOpacity()'>Click me</div>
<div id=changeme class=topping>Hello</div>
<script>

function changeOpacity() {
    x = document.getElementById('changeme');
    x.style.opacity = 1;
}
</script>
 
 我认为您正在寻找的相关位是如何更改不透明度（ x.style.opacity ，或者您可以使用jQuery），但您还需要弄清楚如何将按钮与适当的图像链接。 
 
 与单选按钮可能有点不同，但它基本上是相同的想法。 

Roughly speaking, you need the click to trigger some javascript code that changes the opacity of the relevant target. A quickie example would be something like this:
 
<style>
.topping {
    opacity: 0;
}
</style>
<div onclick='changeOpacity()'>Click me</div>
<div id=changeme class=topping>Hello</div>
<script>

function changeOpacity() {
    x = document.getElementById('changeme');
    x.style.opacity = 1;
}
</script>
 
I think the relevant bit you're looking for is how to change the opacity (x.style.opacity, or you could use jQuery), but you'll also need to sort out how to link the buttons with the appropriate images.
 
And it might be a bit different with radio buttons, but it's essentially the same idea.
