javascript - 放置时使可拖动的快照向左移动

** EDIT **

我目前正在创建一个拖放拼写游戏，用户将字母拖到突出显示的单词上以进行拼写并显示后面的图像。

当单词以“.spellword”样式突出显示时，它指示用户拼写该单词。当用户将字母拖到该区域时，他/她可以将字母拖到3个字母空间中的任何位置，但是我需要将它们从“左”拖放到“右”，以确保单词拼写正确。

基本上，当一个字母被放到单词上时，我需要将其对齐到左侧(单词的第一个字母)，然后下一个字母放到该单词的下一个字母上，依此类推...所以它的拼写顺序正确

我该怎么做才能确保这一点？

可拖放的脚本是...

$('.drag').draggable({
helper: 'clone',
snap: '.drop',
grid: [62, 62],
revert: 'invalid',
snapMode: 'corner',
start: function(){
    var validDrop = $('.drop-box.spellword');
    validDrop.addClass('drop');
    makeDroppables();
}
});


function makeDroppables(){
$('.drop').droppable({
drop: function(event, ui) {
    word = $(this).data('word');
    guesses[word].push($(ui.draggable).attr('data-letter'));

    if ($(this).text() == $(ui.draggable).text().trim()) {

        $(this).addClass('wordglow3');
    } else {
        $(this).addClass('wordglow');
    }


    if (guesses[word].length == 3) {
        if (guesses[word].join('') == word) {
            $('td[data-word=' + word + ']').addClass('wordglow2');

        } else {
            $('td[data-word=' + word + ']').addClass("wordglow4");
            guesses[word].splice(0, guesses[word].length);
        }
    }
},


activate: function(event, ui) {
    word = $(this).data('word');

    // try to remove the class
    $('td[data-word=' + word + ']').removeClass('wordglow').removeClass('wordglow4').removeClass('wordglow3');
}

});

}

最佳答案

就个人而言，我不喜欢使用CSS来达到这种效果的想法。为什么不把字母实际上放在单词的第一个空白处呢？这似乎达到了预期的效果:

http://jsfiddle.net/nickaknudson/sYJwm/

$('.drop').droppable({
...
drop: function(event, ui) {
    word = $(this).data('word');
    //change context from this to that
    that = $('.spellword')[guesses[word].length];
    guesses[word].push($(ui.draggable).attr('data-letter'));

    if ($(that).text() == $(ui.draggable).text().trim()) {

        $(that).addClass('wordglow3');
    } else {
        $(that).addClass('wordglow');
    }


    if (guesses[word].length == 3) {
        if (guesses[word].join('') == word) {
            $('td[data-word=' + word + ']').addClass('wordglow2');

        } else {
            $('td[data-word=' + word + ']').addClass("wordglow4");
            guesses[word].splice(0, guesses[word].length);
        }
    }
},
...
