How to map index using jquery to repair indexes when remove
Problemwhen remove any course from table list html his position in center or first it make problem
in index in database
Details
IF I have list of courses as following :
Delphi
Flash
Photoshop
IF I remove flash by JQUERY remove button then click save button
it delete flash and Photoshop
because there are wrong in delete courses by using remove function in jquery
if i remove php it is working without any problem because it is last item
suggestion
using map function when remove but how to do that
if there are any solution for that without using map no problem
i use model as following
public class Cusomemp2
{
public List<EmployeeCourse> empcourses { get; set; }
}
}
i use for edit httppost
var result = db.Employees
.Where(p => p.Id == custom.Id)
.Include(c => c.EmployeeCourses)
.FirstOrDefault();
if (custom.empcourses.Any())
{
foreach (var ec in result.EmployeeCourses.ToList())//to remove existing EmployeeCourses
{
db.EmployeeCourses.Remove(ec);
db.SaveChanges();
}
}
result.EmployeeCourses = custom.empcourses;
db.SaveChanges();
in model view my code as following by jquery
actually i need to modify code below using map function if there are any function do that never mind
$(function () {
//add courses using drop down
var index = 0;
$("#CourseId").change(function () {
var id = $(this).val();
var txt = $("#CourseId option:selected").text();
$("#tb").append("<tr><td><input type = 'hidden' name='empcourses[" + index + "].CourseId' value='" + id + "'/></td><td>" + txt + "</td><td><input type='button' value='remove' class='r'</td></tr>")
index++;
});
$("#tb").on("click", ".r", function () {
// remove function
$(this).parent().parent().remove();
$(this).parent().prev().prev().remove();
});
// retrieve data in edit view using ajax
$.ajax({
url: "/Employee/getcoursesbyempid",
data:{x:$("#hid").val()},
success: function (res) {
$.each(res, function (i, e) {
$("#tb").append("<tr><td><input type = 'hidden' name='empcourses[" + index + "].CourseId' value='" + e.Id + "'/></td><td>" + e.CourseName + "</td><td><input type='button' value='remove' class='r'</td></tr>")
index++;
});
}
})
});
