Is there any way to control scroll bar using JavaScript?
提问by Mad coder.
In my below code a function to scroll DIV for every set of intervals where when I try to scroll up due to interval refresh scroll bar again coming down.
在我下面的代码中,一个函数可以为每组间隔滚动 DIV,当我尝试向上滚动时,由于间隔刷新滚动条再次下降。
My code:
我的代码:
var int = self.setInterval("f2()", 1000);
function f2() {
var objDiv = document.getElementById("messages2");
objDiv.scrollTop = objDiv.scrollHeight;
}
Now, by using onscroll
property for DIV is there anyway to stop scrolling down when holding scroll bar with mouse?
现在,通过onscroll
对 DIV使用属性,是否可以在用鼠标按住滚动条时停止向下滚动?
Something like
就像是
var int = self.setInterval("f2()", 1000);
function f2() {
var objDiv = document.getElementById("messages2");
// if(objDiv.onscroll) i.e. when the particular DIV's scroll bar is on hold by cursor.
{
return false;
}
else
{
objDiv.scrollTop = objDiv.scrollHeight;
}
}
If the above kind of function can be implemented anybody please correct its syntax. I am a newbie to JavaScript.
如果任何人都可以实现上述类型的功能,请更正其语法。我是 JavaScript 的新手。
Thanks in advance..!
提前致谢..!

I'm not sure what you are asking here, but window
has a scroll event that you can listen to, and so does any other element that has overflow: auto|scroll
set using CSS.
我不确定您在这里问的是什么,但是window
有一个可以收听的滚动事件,overflow: auto|scroll
使用 CSS 设置的任何其他元素也是如此。
You can't prevent the default scrolling behavior, but you can use the scrollTo()
method or the scrollTop
property if you want to do something annoying like:
您无法阻止默认滚动行为,但是如果您想做一些烦人的事情,可以使用scrollTo()
方法或scrollTop
属性,例如:
window.onscroll = function() {
window.scrollTo(0,0);
};
Here is a nice compat table of the scroll event: http://www.quirksmode.org/dom/events/scroll.html
