Use JS to implement page deletion and reordering functions

First, use the jqury selector to select the checked row:

var cks = $("#indicator_table").find("input[type='checkbox']:checked");

Then a confirmation box will pop up to confirm whether to delete the box. Bind a delInd() event;

First remove or html (" ") the selected line on the page,

$("#indicator_table").find("input[type='checkbox']:checked").each(function(i, o){
// 获取checkbox所在行的顺序 
n = $(this).parents("tr").index();
$("#indicator_table").find("tr:eq(" + n + ")").remove();
});
$("#deleteModal").modal("hide");

After reordering the remaining rows, jqury selector is needed to select the rows of the table and perform circular assignment:

$("#indicator_table").find("tr").each(function(i){
$(this).find("td").eq(10).find("a").text(i+1);
});
