下面的代码选择随机图像,我想让它线性选择并在下次刷新时显示接下来的8个图像。
$.fn.preload = function() {
this.each(function(){
$('<img/>')[0].src = this;
});
}
function preloadImg(totalClients)
{
for(var i = 1; i <= totalClients; i++)
{
$('<img src="images/clients/' + i + '.jpg"/>');
}
}
function getRandoms(numPicks, low, high) {
var len = high - low + 1;
var nums = new Array(len);
var selections = [], i;
// initialize the array
for (i = 0; i < len; i++) {
nums[i] = i + low;
}
// randomly pick one from the array
for (var i = 0; i < numPicks; i++) {
var index = Math.floor(Math.random() * nums.length);
selections.push(nums[index]);
nums.splice(index, 1);
}
return(selections);
}
function randomClients(totalClients)
{
rarr = getRandoms(8,1,totalClients);
$(".pretty-box").each(function(index)
{
$(this).fadeOut(function(){
src = "images/clients/" + rarr[index] + ".jpg" ;
$(this).attr('src',src);
$(this).fadeIn();
});
});
}
我们可以从我们的阵列中选择前8个图像,但不能选择接下来的8个图像。 有人可以帮助我们吗?
