我有一个带有LOOP的轮播图像的脚本
$(document).ready(function() {
//rotation speed and timer
var speed = 5000;
var run = setInterval(rotate(), speed);
//grab the width and calculate left value
var item_width = $('#slides li').outerWidth();
var left_value = item_width * (-1);
//move the last item before first item, just in case user click prev button
$('#slides li:first').before($('#slides li:last'));
//set the default item to the correct position
$('#slides ul').css({'left' : left_value});
//if user clicked on next button
function rotate() {
//get the right position
var left_indent = parseInt($('#slides ul').css('left')) - item_width;
//slide the item
$('#slides ul').animate({'left' : left_indent}, 3000, function () {
//move the first item and put it as last item
$('#slides li:last').after($('#slides li:first'));
//set the default item to correct position
$('#slides ul').css({'left' : left_value});
});
//cancel the link behavior
return false;
}
});
但是我在firebug中收到了这个javascript错误:
无用的setInterval调用(参数周围缺少引号?) [Interrompi per questo errore] var run = setInterval(rotate(),speed);
我认为它是旋转功能定义的错误!
答案 0 :(得分:4)
这意味着你应该写:
var run = setInterval(rotate, speed);
而不是
var run = setInterval(rotate(), speed);
因为你需要将函数的引用传递给setInterval,你传递的是函数rotate()的返回值;
