How to put scrolling text in title tag?
提问by Yadav Chetan
I want to make text of title scrollable, I make the code as under it scrolls fine but the text I entered is displayed without space, meaning space in string is not considered.
我想让标题文本可滚动，我使代码在它下面滚动得很好，但我输入的文本显示时没有空格，这意味着不考虑字符串中的空格。
<script type="text/javascript">
//function for tittle scrolling
function scrlsts() {
//var scrltest = " Nature ";
scrltest=document.title;
//alert(scrltest);
scrltest = scrltest.substring(1, scrltest.length) + scrltest.substring(0, 1);
//alert(scrltest);
document.title = scrltest;
setTimeout("scrlsts()", 1000);
}
$(document).ready(function() {
var scrltest = " Nature dff ssfd ";
document.title=scrltest;
scrlsts();
});
</script>
Thanks in advance
提前致谢

Haven't made these for a long time, but this should work:
很久没有做这些了，但这应该有效：
(function titleScroller(text) {
document.title = text;
setTimeout(function () {
titleScroller(text.substr(1) + text.substr(0, 1));
}, 500);
}(" Nature dff ssfd "));

<script type='text/javascript'>
title = "Your Title";
position = 0;
function scrolltitle() {
document.title = title.substring(position, title.length) + title.substring(0, position);
position++;
if (position > title.length) position = 0;
titleScroll = window.setTimeout(scrolltitle,170);
}
scrolltitle();
</script>
To stop the title scroll, just run:
要停止标题滚动，只需运行：
window.clearTimeout(titleScroll);

You can try this :
你可以试试这个：
<script>
var repeat=0 //enter 0 to not repeat scrolling after 1 run, othersise, enter 1
var title=document.title
var leng=title.length
var start=1
function titlemove()
{
titl=title.substring(start, leng) + title.substring(0, start)
document.title=titl
start++
if (start==leng+1`enter code here`)
{
start=0
if (repeat==0)
return
}
setTimeout("titlemove()",500)
}
if (document.title)
titlemove()
</script>
