我正在尝试添加索引并删除单独添加的行。我尝试使用 div 的长度，但如果我将它附加到输入框的前面，它不会触发。这是 plunker http://plnkr.co/edit/4P6HWu9jVTmZhOnEhMdb?p=preview

【解决方案1】：
给你：
$('#add').click(function() {
var x = $('<div class="ui-state-highlight">' + ($('.con div').length + 1) + '<input type="text" class="form-control" ng-model="input.field" placeholder="Name"/><input type="text" class="form-control" ng-model="input.value" placeholder="Email"/><a href="a"><span class="glyphicon glyphicon-move"></span></a><input type="button" class="form-control Minus" value="-" /></div>');
x.appendTo('#form .con') // the length is not working here if I use it in the front of the div while declairng the variable.
});
$('.con').on('click', '.Minus', function() {
$(this).parents(".ui-state-highlight").remove();
});
$("span").sortable({
connectWith: ".con"
}).disableSelection();

- 你有两个
class 声明，所以我将它们合并得到 form-control Minus 类。
- 还修复了
.on() 处理程序的选择器。
编辑：
您的新行标记由
定义
var x = $('<div class="ui-state-highlight"><input type="text" class="form-control" ng-model="input.field" placeholder="Name"/><input type="text" class="form-control" ng-model="input.value" placeholder="Email"/><a href="a"><span class="glyphicon glyphicon-move"></span></a><input type="button" class="form-control Minus" value="-" />' + ($('.con div').length + 1) + '</div>');
要将索引移到前面，请将($('.con div').length + 1) 移到前面，如下所示：
var x = $('<div class="ui-state-highlight">' + ($('.con div').length + 1) + '<input type="text" class="form-control" ng-model="input.field" placeholder="Name"/><input type="text" class="form-control" ng-model="input.value" placeholder="Email"/><a href="a"><span class="glyphicon glyphicon-move"></span></a><input type="button" class="form-control Minus" value="-" /></div>');
