我正在尝试使用 Bootstrap 和 jQuery 制作我自己的多步骤表单。但是，当单击“下一步”按钮时，上一个 Pane 不会被下一个/新 Pane 替换，而是新 Pane 出现在上一个 Pane 的正下方。
//jQuery time
var current_fs, next_fs, previous_fs; //fieldsets
var left, opacity, scale; //fieldset properties which we will animate
var animating; //flag to prevent quick multi-click glitches
$(".next").click(function(){
if(animating) return false;
animating = true;
current_fs = $(this).parent();
next_fs = $(this).parent().next();
//activate next step on progressbar using the index of next_fs
$("#progressbar li").eq($("fieldset").index(next_fs)).addClass("active");
//show the next fieldset
next_fs.show();
//hide the current fieldset with style
current_fs.animate({opacity: 0}, {
step: function(now, mx) {
//as the opacity of current_fs reduces to 0 - stored in "now"
//1. scale current_fs down to 80%
scale = 1 - (1 - now) * 0.2;
//2. bring next_fs from the right(50%)
left = (now * 50)+"%";
//3. increase opacity of next_fs to 1 as it moves in
opacity = 1 - now;
current_fs.css({
'transform': 'scale('+scale+')',
'position': 'absolute'
});
next_fs.css({'left': left, 'opacity': opacity});
},
duration: 800,
complete: function(){
current_fs.hide();
animating = false;
},
//this comes from the custom easing plugin
easing: 'easeInOutBack'
});
});
$(".previous").click(function(){
if(animating) return false;
animating = true;
current_fs = $(this).parent();
previous_fs = $(this).parent().prev();
//de-activate current step on progressbar
$("#progressbar li").eq($("fieldset").index(current_fs)).removeClass("active");
//show the previous fieldset
previous_fs.show();
//hide the current fieldset with style
current_fs.animate({opacity: 0}, {
step: function(now, mx) {
//as the opacity of current_fs reduces to 0 - stored in "now"
//1. scale previous_fs from 80% to 100%
scale = 0.8 + (1 - now) * 0.2;
//2. take current_fs to the right(50%) - from 0%
left = ((1-now) * 50)+"%";
//3. increase opacity of previous_fs to 1 as it moves in
opacity = 1 - now;
current_fs.css({'left': left});
previous_fs.css({'transform': 'scale('+scale+')', 'opacity': opacity});
},
duration: 800,
complete: function(){
current_fs.hide();
animating = false;
},
//this comes from the custom easing plugin
easing: 'easeInOutBack'
});
});
$(".submit").click(function(){
return false;

感谢所有帮助，谢谢!
最佳答案
这个问题有两个原因:
- 精简版的 jQuery 没有动画功能。
- 您错过了包含自定义缓动插件。
因此要更正导入，您需要添加:
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-easing/1.4.1/jquery.easing.min.js"></script>
并使用缩小版本而不是 jQuery 的精简版本。
希望对您有所帮助。
