If you look at the js fiddle you will find clicking the thumbail changes the image aswell as the .currentimgtitle text value but it changes all .currentimgtitle text values on the page when i only want to change the one relevant to it the jquery and html are below

$(".imgcontainer").each(function() {
    var imgsrc = $(".minicontainer img:first-child", this).attr("src");
    var imgtitle = $(".minicontainer img:first-child", this).attr("title");
    $(this).append('<div class="presentouter"><img src="' + imgsrc + '" class="presentimg"/><div class="currentimgtitle" title="' + imgtitle + '">' + imgtitle + '</div></div>');
});
$(".miniimg, .miniimg2, .miniimg3").click(function() {
    var miniimgrc = $(this).attr("src"),
        $presentImg = $(this).closest(".imgcontainer").find(".presentimg");

    $presentImg.attr('src', miniimgrc);
});
$(".miniimg, .miniimg2, .miniimg3").click(function(index) {
    var miniimgtitle = $(this).attr("title"),
        $presentTitle = $(this).closest(".imgcontainer").find(".currentimgtitle");

    $presentTitle.attr('title', miniimgtitle);

});
$(".imgcontainer").each(function(index) {
$(".miniimg, .miniimg2, .miniimg3").click(function() {
    var textval =  $(this).attr("title");
    $(".currentimgtitle").text(textval);

回答1:

why don't you change

$(".currentimgtitle").text(textval);

to

$(this).closest(".imgcontainer").find(".currentimgtitle").text(textval);

like you did a few lines higher ?

回答2:

While I see you've already accepted an answer, this approach seems to work pretty well:

$('.minicontainer img').click(
    function(){
        var miniImgSrc = this.src,
            imgTitle = this.title,
            $container = $(this).closest('.imgcontainer');
        $container
            .find('.presentimg')
            .attr('src',miniImgSrc);
        $container
            .find('.currentimgtitle')
            .attr('title',imgTitle)
            .text(imgTitle);
    });

try this example, a bit cleaner. For the next step i`ve better wrap it in for no js users.
