Javascript Marquee替换<marquee>标签

Question

我对Javascript毫无希望.这就是我所拥有的:

<script type="text/javascript">
    function beginrefresh(){

        //set the id of the target object
        var marquee = document.getElementById("marquee_text");

        if(marquee.scrollLeft >= marquee.scrollWidth - parseInt(marquee.style.width)) {
            marquee.scrollLeft = 0;
        }

        marquee.scrollLeft += 1;

        // set the delay (ms), bigger delay, slower movement
        setTimeout("beginrefresh()", 10);

    }
</script>

它滚动到左边但我需要它相对无缝地重复.目前它只是跳回到开头.这可能不是我做的方式,如果没有,任何人都有更好的方法？

Answer 2

简单的JavaScript解决方案:

window.addEventListener('load', function () {
	function go() {
		i = i < width ? i + step : 1;
		m.style.marginLeft = -i + 'px';
	}
	var i = 0,
		step = 3,
		space = '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;';
	var m = document.getElementById('marquee');
	var t = m.innerHTML; //text
	m.innerHTML = t + space;
	m.style.position = 'absolute'; // http://stackoverflow.com/questions/2057682/determine-pixel-length-of-string-in-javascript-jquery/2057789#2057789
	var width = (m.clientWidth + 1);
	m.style.position = '';
	m.innerHTML = t + space + t + space + t + space + t + space + t + space + t + space + t + space;
	m.addEventListener('mouseenter', function () {
		step = 0;
	}, true);
	m.addEventListener('mouseleave', function () {
		step = 3;
	}, true);
	var x = setInterval(go, 50);
}, true);

#marquee {
   background:#eee;
   overflow:hidden;
   white-space: nowrap;
 }

<div id="marquee">
	1 Hello world! 2 Hello world! <a href="#">3 Hello world!</a>
</div>
