我有一个包含下一个和上一个按钮的 4 步表单。我正在使用 jQuery Validation 来验证表单。
当您单击“下一步”时，它会验证表单，但是，如果您未通过该验证步骤，则“下一个”或“上一个”按钮都不再起作用。
下面是我的代码。有人有建议吗？
Javascript:
$(document).ready(function() {
$("body").on('click', '.next', function(){
if(animating) return false;
animating = true;
var type = $(this).parent().parent().attr("id");
if(type == "business_form"){
if($("#business_form").valid() == true){
$("#return-login2").hide();
current_fs = $(this).parent();
next_fs = $(this).parent().next();
//activate next step on progressbar using the index of next_fs
$("#progressbar li").eq($("#business_form 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+')'});
next_fs.css({'left': left, 'opacity': opacity});
},
duration: 800,
complete: function(){
current_fs.hide();
animating = false;
},
});
}
}
});
$("body").on('click', '.previous', 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;
},
});
});
$("#business_form").validate({

最佳答案
正是以下这句话阻止了你，伙计。
$("body").on('click', '.next', function(){
if(animating) return false; //try commenting this statement
animating = true;
//Other code
}
当您第一次单击下一步按钮时，animating 变量将未定义。因此它将动画变量重新初始化为 true。第二次单击下一步按钮时，将根据条件检查变量。由于变量是全局声明的，并且先前的值被设置为true，因此它满足条件返回 false 并阻止你进入下一步。希望这能让你知道你可能做错了什么，伙计..:)
