我尝试为表单创建一个逐步进度栏,但是我想让进度栏的圆点上方每隔一个第二个“文本框”,以使元素文本在彼此之间不会互相干扰浏览器窗口变小.
有没有简单的方法可以做到这一点？
片段显示了运行中的进度栏.
var progressBar = {
Bar : $('#progress-bar'),Reset : function(){
if (this.Bar){
// this.Bar.find('li').addClass('active');
}
},Next: function(){
$('#progress-bar li:not(.active):first').addClass('active');
},Back: function(){
$('#progress-bar li.active:last').removeClass('active');
}
}
progressBar.Reset();
////
$("#Next").on('click',function(){
progressBar.Next();
})
$("#Back").on('click',function(){
progressBar.Back();
})
$("#Reset").on('click',function(){
progressBar.Reset();
}) .progressbar {
margin: 50px 0 50px 0;
counter-reset: step;
}
.progressbar li {

</html>最佳答案
您需要使用.progressbar li：nth-child(2n)来定位其他所有li元素,然后需要将整个伪元素向上移动,然后将线和圆(：before和：after)向下移动.如果您没有将文本,行和圆全部都附加到同一元素/伪元素,这将容易得多.
查看代码段：
var progressBar = {
Bar: $('#progress-bar'),Reset: function() {
if (this.Bar) {
// this.Bar.find('li').addClass('active');
}
},Next: function() {
$('#progress-bar li:not(.active):first').addClass('active');
},Back: function() {
$('#progress-bar li.active:last').removeClass('active');
}
}
progressBar.Reset();
////
$("#Next").on('click',function() {
progressBar.Next();
})
$("#Back").on('click',function() {
progressBar.Back();
})
$("#Reset").on('click',function() {
progressBar.Reset();
}).progressbar {
margin: 50px 0 50px 0;
counter-reset: step;

</html>以下CSS规则可以解决问题：
.progressbar li:nth-child(2n) {
top: -50px;
}
.progressbar li:nth-child(2n):after {
top: 57px;
}
.progressbar li:nth-child(2n):before {
top: 50px;
}
