javascript从PHP Echo更改锚标记标题值

Question

I have a class assigned to an anchor tag called status_button. On click of the image associated with the anchor tag it runs the attached function. Two variables are passed to a php script and a 3 piece data response is echo'ed back separated by semicolon's. I have set up alerts to ensure the correct data is coming back from php.

The thing I need help with is how to change the anchor tag title value using the echo'ed response. There are 5 examples out of probably 20 that I have tried. None of them work, but I get no error's either. Any help would be greatly appreciated.

$(".status_button").on('click', function () {
    var element = $(this);
    var I = element.attr("id");
    var id = $("#id" + I).val();
    var sname = $(this).attr("title");
    $.post("openclose.php", {
        id: id,
        sname: sname
    },      
    function (data) {
        var response = (data).split(";", 3);
        alert(response[0]);
        alert(response[1]);
        alert(response[2]);

        $("#messageA" + I).innerhtml = (response[0]);
        $("#messageA" + I).hide();
        $("#messageA" + I).fadeIn(1500);
        $("#messageB" + I).html(response[1]);
        $("#messageB" + I).hide();
        $("#messageB" + I).fadeIn(1500);

        ***$(this).attr("title",(response[2]));
        ***$(I).attr("title", (response[2]));
        ***$("#id" + I).attr("title" , (response[2]));
        ***document.getElementById(I).title = (response[2]);
        ***document.getElementById("#id" +I).setAttribute("title",(response[2]));
    });
    return false;
});

Answer 1

This will work:

$("#1").attr("title", (response[2]));

Your attempts:

    ***$(this).attr("title",(response[2])); //this is no longer referring to the clicked element when inside the callback
    ***$(I).attr("title", (response[2])); //Missing # for ID
    ***$("#id" + I).attr("title" , (response[2])); //Not your element ID
    ***document.getElementById("#id" +I).setAttribute("title",(response[2])); //Not your ID

Answer 2

Well.... I had to change a few things around to get this to work the way I needed it to. First off I removed the title from my anchor tag and placed it in my div tag. I then reduced my response from my php file from 3 down to 2 pieces of data.

$(".status_button").on('click', function () {
    var element = $(this);
    var I = element.attr("id");
    var id = $("#id" + I).val();
    var xname = $("#messageA" + I).attr('title');
    $.post("openclose.php", {
        id: id,
        xname: xname
    },      
    function (data) {
    var response = (data).split(";", 2);
        $("#messageA" + I).attr('title', (response[0]));        
        $("#messageB" + I).html(response[1]);
        $("#messageB" + I).hide();
        $("#messageB" + I).fadeIn(1500);

    });
    return false;
});
