这是一个简单的滚动文本!
以下工作:
原始代码的问题是,通过将字符串传递到setInterval
,调用scrollticker()
,您只需传递函数名并将其视为变量:
lefttime = setInterval(scrollticker, 50);
而不是
lefttime = setInterval("scrollticker()", 50);
hiya简单演示来自上述评论中的建议: 使用鼠标上方的暂停功能: 希望这有帮助,祝你玩得愉快,干杯 html
<h1>Hello World!</h1>
<h2>I'll marquee twice</h2>

你好,世界!
我要选两次
我跑得很快!

我为marquee制作了非常简单的函数。请参见:

function marquee(a, b) {
var width = b.width();
var start_pos = a.width();
var end_pos = -width;
function scroll() {
if (b.position().left <= -width) {
b.css('left', start_pos);
scroll();
}

time = (parseInt(b.position().left, 10) - end_pos) *
(10000 / (start_pos - end_pos)); // Increase or decrease speed by changing value 10000
b.animate({
'left': -width
}, time, 'linear', function() {
scroll();
});
}

b.stop(); //

}); //
b.mouseleave(function() { // marquee to pause
scroll(a, b); //
}); // on mouse over
}
$(document).ready(function() {
marquee($('#display'), $('#text')); //Enter name of container element & marquee element
});
函数选框(a、b){
变量宽度=b.宽度();
var start_pos=a.宽度();
var end_pos=-宽度;
函数滚动(){
如果(b.position().left我刚刚为此创建了一个简单的jQuery插件,试试看;)
我根据上面@Tats\u innit提供的代码制作了自己的版本。
区别在于暂停功能。在这方面效果更好
