Question

我一直在寻找可拖动元素的智能指南，并在这里找到了一个不错的脚本 - https://stackoverflow.com/a/22062111

它完美地工作，直到我改变了一点结构。如果包装器对齐显示，则指南未正确显示：inline-block或float：left

我在这里创造了一个小提琴 - http://jsfiddle.net/A6CpP/110/

$.ui.plugin.add("draggable", "smartguides", {
    start: function(event, ui) {
        var i = $(this).data("draggable");
    console.log(i);
    var o = i.options;
        i.elements = [];
        $(o.smartguides.constructor != String ? ( o.smartguides.items || ':data(draggable)' ) : o.smartguides).each(function() {
            var $t = $(this); var $o = $t.offset();
            if(this != i.element[0]) i.elements.push({
                item: this,
                width: $t.outerWidth(), height: $t.outerHeight(),

您可以尝试其他插件。我为可拖动和可调整大小的插件添加了智能指南功能。

$('.drag')
    .draggable({
        smartGuides: '.drag:not(".selected")'
    })
    .resizable({
        handles: 'all',
        smartGuides: '.drag:not(".selected")'
    }

你可以看到它的工作原理：
