我从网上复制了这段代码，来自 here
它用于通过滑出旧字段集并滑入新字段集来在单个模态中显示多个表单。
<div class="modal-content">
<!-- MultiStep Form -->
<div class="row">
<div class="col-md-12 ">
<form id="msform" name="flatform" ng-submit="addflatinfo(flat, flatform)" novalidate>
<div class="modal-header">
<h4 class="modal-title" id="exampleModalLabel">Add flat</h4>
</div>
<!-- First fieldset -->
<fieldset class="firstFieldSet">
<h4>
adf
</h4>
<div class="row">
....
<input type="button" name="nextOcc"
class="nextO action-button
adFlatSecondFieldsetCl"
value="Next" />
</fieldset>
<!--Second fieldset -->
<fieldset class="secondFieldSet">
<h4>
adf
</h4>
<div class="row">
....
</fieldset>
它工作正常，但是当我在第二个或第三个或第四个字段集中关闭模态时，它会显示我停止的字段集。因此，每当我单击按钮打开模式时，我都尝试执行上一个按钮将执行的操作(滑出当前字段集并显示前一个字段集)。
我的应用程序中有 5 个字段集。我跟踪当前的字段集，当再次打开模态时，我滑出关闭模态之前存在的字段集并显示第一个字段集。
但这不行.. 我在一个较大的字段集上看到一个较小的字段集，有时我除了模态标题什么都看不到，有时只是一个小的字段集，如下图所示，它全都搞砸了。
如何在打开模式时始终显示第一个字段集？
单击具有 .nextO 类的按钮时显示下一个字段集的代码。
current_fs = $(".nextO").parent();
next_fs = $(".nextO").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'
});
转到上一个字段集的代码(这是我在首次打开模式时使用的代码，因此它始终显示第一个)。
if(animating) return false;
animating = true;
//fade remove the fieldset which was open before closing the modal -- $scope.currentAdFieldset
current_fs = $($scope.currentAdFieldset).parent();
previous_fs = $('.adFlatSecondFieldsetCl').parent().prev();
$("#progressbar li").eq($("fieldset").index(current_fs)).removeClass("active");
console.log(previous_fs, "prevfs");
previous_fs.show();
current_fs.animate({opacity: 0}, {
step: function(now, mx) {
scale = 0.8 + (1 - now) * 0.2;
left = ((1-now) * 50)+"%";
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'
});
当我打开模式时，是否有正确的方法来显示第一个字段集。这就是它的样子。字段集不填充模态
编辑:
我在打开模式的按钮的 ng-click 上尝试了这个
$('.modal-content fieldset').css('opacity', '0');
$('.modal-content fieldset').first().css('opacity', '1');
$('.modal-content fieldset').first().show();
$("#progressbar li:not(:eq(0))").removeClass('active');
$('#apartmentsmodel').modal({ backdrop: 'static', keyboard: false, show: true });
编辑 2:
我尝试了这个以及答案所说的并且有效:
$('.modal-content fieldset').css({'opacity': '0','display':'none', 'transform' : 'scale(1)'});
$('.modal-content fieldset').first().css({'opacity': '1', 'transform' : 'scale(1)', 'display':'block'});
最佳答案
试试这个片段。它使用 show.bs.modal 事件 ( more info ) 来检查是否打开了模式。
<script type="text/javascript">
$(document).ready(function () {
$('body').on('show.bs.modal', function () {
//hide all the fieldsets
$('.modal-content fieldset').css('opacity', '0');
//show the first fieldset
$('.modal-content fieldset').first().css('opacity', '1');
$('.modal-content fieldset').first().show();
//make sure the progress bar also show the first only
$("#progressbar li:not(:eq(0))").removeClass('active');
});
});
</script>
这是使用 plugin you specified 中的示例代码测试的.在 Bootrap 4 模式中使用该站点上下载的 html、css 和 jquery，它起作用了。
