In our daily life we need to use some jQuery methods like addClass, removeClass, add ID or remove ID etc. So today i created a single page where user can find this all in one place.

1) jQuery addClass()

    $( "#YOURID" ).addClass( "yourClass" );

2) jQuery removeClass()

    $( "#YOURID" ).removeClass( "yourClass" );

3) jQuery Add ID to Div()

    $( "#YOURID" ).attr('id', 'value');

4) jQuery Remove ID from Div()

    $( "#YOURID" ).removeAttr('id');

5) String replace

    var str = "My name is Hardik";
    var res = str.replace("Hardik", "HK");

6) Get value of text box

    var myval = $("#txtname").val();

    alert(myval );

7) Set value of text box

    $("#txtname").val("something");

8) Check element has class

    if($("#YOURID").hasClass("ClassName"))
    {
          alert("Class found");
    }

    else
    {
          alert("Class not found");
    }

9) Submit page

    $("#FORMID").submit();

10) Jquery ajax function
    $.ajax({
        type: "POST",
        url: "(URL OF YOUR PAGE)",
        data: 'id='+id+'&name='+name,
        success: function(data)
       {

        }
   },
   error: function(xhr, ajaxOptions, thrownError) { alert(xhr.responseText); }
  });
