有人可以正确区分scrollTop和scrollHeight吗？ [英] Can someone canonically differentiate between scrollTop and scrollHeight?

问题描述

例如，

  function fnCheckScroll（）{
 var iNewHeight = oDiv.scrollHeight; 
 var iscrolTop = oDiv.scrollTop; 
 alert（scrollHeight属性的值是：+ iNewHeight +px）; 
 alert（scrollTop属性的值是：+ iscrolTop +px）; 
} 
 
< div id =oDivstyle =overflow：scroll; height = 100px; width = 250px; text-align：left> 
你好< br> 
< / div> 
  

在IE 8中，scrollTop的值总是：0 - 为scrollTop返回0（即使滚动后）？

解决方案

如果我在此窗口中向下滚动5px，窗口的 scrollTop value是5.如果我在可滚动的div中向右滚动10px，div的 scrollLeft 值为10。

当我滚动到这个窗口的左上角时，它的 scrollTop 和 scrollLeft 值都是0。 p>

For example,

function fnCheckScroll(){   
    var iNewHeight = oDiv.scrollHeight;
    var iscrolTop = oDiv.scrollTop; 
    alert("The value of the scrollHeight property is: "  + iNewHeight + "px"); 
    alert("The value of the scrollTop property is: " + iscrolTop + "px");        
}

<div id="oDiv" style="overflow: scroll; height= 100px; width= 250px; text-align: left">
Hello<br>
</div>

In IE 8, the value of scrollTop is always: 0 - returns 0 for scrollTop (even after scrolling)?

解决方案

If I scroll down 5px in this window, the window's scrollTop value is 5. If I scroll right 10px in a scrollable div, the div's scrollLeft value is 10.

When I scroll to the top left corner of this window, both its scrollTop and scrollLeft values are 0.
