JS代码。
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'
});
});
我使用的模板是 https:/codepen.ioatakanpengqbIz。
我想当下一个按钮的输入窗体全部填写完毕,如果没有在所有输入窗体填写完毕之前,下一个按钮就不能发挥作用。
请帮我修改JS中的 https:/codepen.ioatakanpengqbIz。 . 谢谢你
在下面的JS脚本旁边添加 $(".next").click(function()) { 将验证表单字段。请确保在每个字段组中添加Id属性。
Example: <fieldset id="f1">, <fieldset id="f2"> and <fieldset id="f3">
_p_id = $(this).parent().attr('id');
$('#msform #'+ _p_id + ' input').each(function(){
if ($.trim($(this).val()).length == 0){
isFormValid = false;
return false;
}else{
isFormValid = true;
}
});
if(!isFormValid){
return false;
}
