Jquery 名称列表选项列表保持乘法 函数addteamSection（）{ var teamList=$（“#team_table”）； var团队_临时=“”； 变量大小_temp=[“20”、“30”、“40”、“50”、“60”]； 团队列表。追加（“”）； 对于（变量s=0；s

我的意图是通过点击按钮创建一个添加名称列表，它将有年龄选择供用户选择，但我的选项保持乘法，因为我有相同的类名，但我假设如何添加以选择不使用任何id，并确保它不是乘法

---

保持单击几次添加并选中第一个选项，然后重复

像这样分开你的字符串构建

函数addteamSection（）{
var teamList=$（“#team_table”）；
var团队_临时=“”；
变量大小_temp=[“20”、“30”、“40”、“50”、“60”]；
var rowString=“”
var selectString=“”
/*而不是使用var sizeList=$（'.sizeList'）；来选择新的下拉列表
（由于新元素尚未添加到
您可以手动构建选择框，将选项附加到该框中
然后将其附加到DOM元素中*/
对于（变量s=0；s

AdityaParab你在吗？你能帮我再检查一下吗？我试着在里面添加循环号，我试着像你一样断开循环。为什么不工作？我要加1。2.3.
