Question

在我的春季启动项目中，我有一个l1 <- list() # Initialize empty list for (i in 1:nrow(df)){ l1[[i]] <- transform(df[i,]) # Fill list with transformed rows } DF1 <- data.frame(do.call("rbind",l1)) # Bind the transformed rows together页面，其中包含学生列表。在该页面中，我为每个学生提供了两个选项html和Edit。当我点击Delete时，我希望在每个学生信息的模态中显示值。但我无法做到这一点。另一个奇怪的事情是每次我点击任何Edit时，表单只会填充列表的第一个成员。也许我将不得不添加一些Edit代码或其他内容。这里是学生列表页面 ![enter image description here ] 1

最后在堆栈上花了1个小时流量我找到了解决方案。我在我的HTML代码中改变了一点

<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Edit </button>

到

 <button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal" th:attrappend="data-target=${student.id}">Edit </button>

和<div class="modal fade" id="myModal" role="dialog"> 到

<div class="modal fade" id="myModal" role="dialog" th:attrappend="id=${student.id}">

现在一切正常！
