[帮助支持正在使用JSP和Jquery的项目。有一个问题，他们将输入框命名为数组，然后将表单序列化为JSON。问题是他们在表单上有一个删除按钮，并且在提交之前没有重命名输入框。 JAVA代码将其视为数组中的空行。有没有办法遍历这些元素并在Jquery中对其重命名（重编号）？

是，您可以随时获取这些元素并更新其name属性；查看内嵌评论。
deleteThisAssigneeFromSet : function(btn, remove) {
// Get the buttons' parent `tr` (I'd use `closest`, not `parents`)
var parent = $(btn).closest('tr');
if( ! parent.hasClass('pte_row_markup') ) {
// Get the row's siblings
var siblings = parent.siblings('tr');
// Remove the row
parent.remove();
// Update the inputs in the rows, row-by-row
siblings.each(function(i) {
var brackets = "[" + i + "]";
// Uses an "attribute starts with" selector to find the inputs
$(this).find("[name^=assignmentSetGridList]").each(function() {
this.name = this.name.replace(/\[\d+\]/, brackets);
});
});
}
