问题描述

我想建立进度选单列(类似于piccsy投资者的 http:// www。 piccsy.com/investors/



它测量网页的高度和进度%。



感谢您,
Nikola。

解决



首先是div:

 < div id =bar>< / div> 

现在一些样式:

  body {
height:4000px;
}

#bar {
position:fixed;
background-color:red;
width:100%;
height:10px;
}

最后是jQuery代码:

  var bar = $('#bar'),
$ window = $(window),
docHeight = $ (),
baseX = $ window.height()/ docHeight * 100;

bar.css('background','-webkit-linear-gradient(left,red'+ baseX +'%,green'+ baseX +'%)');

$ window.scroll(function(e){
var x = $ window.scrollTop()/ docHeight * 100 + baseX;
bar.css '-webkit-linear-gradient(left,red'+ x +'%,green'+ x +'%)');
}

您可以在 jsfiddle



请注意,这仅适用于Google Chrome,因为我只使用 -webkit-linear-gradient 。如果你想确保它在所有浏览器中都有效,你应该添加它的特定属性。您可能会发现有用的前缀


I'm trying to build progress menu bar(similar to one on the piccsy investors http://www.piccsy.com/investors/ )

It measures the height of the page and progresses %.

Any ideas on how to do it?

Thanks, Nikola.

解决方案

Here you have a solution for this issue.

First of all the div:

<div id="bar"></div>​

Now some styling:

body{
    height:4000px;
}

#bar{
    position:fixed;
    background-color:red;
    width:100%;
    height:10px;
}​

And finally the jQuery code:

var bar = $('#bar'),
    $window = $(window),
    docHeight = $(document).height(),
    baseX = $window.height() / docHeight * 100;

bar.css('background', '-webkit-linear-gradient(left, red '+ baseX +'%, green '+ baseX +'%)');

$window.scroll(function(e) {      
    var x = $window.scrollTop() / docHeight * 100 + baseX;
    bar.css('background', '-webkit-linear-gradient(left, red '+ x +'%, green '+ x +'%)');
});

​You can find a working example in jsfiddle.

Note that this only works in Google Chrome, as I have only used -webkit-linear-gradient. If you want to make sure it works in all browsers you should add its specific property. You may find useful Prefixr for that.
