【问题描述】：
场景
我有一个仪表板，其中一些小部件分组到用户可以单击的选项卡中。小部件具有默认的起始位置，包括高度和宽度，但如果用户移动或调整它们的大小（使用gridstack.js），我会将新的小部件数据保存到本地存储。
如果用户在选项卡之间单击，新的小部件位置将保持不变。
问题
当用户刷新页面时，会加载默认的小部件位置，而不是本地存储中的数据。我尝试使用getWidgetData() 设置新位置，但没有成功。
我已经检查了我的 grid-layout 数据的本地存储，并且存在新位置。
代码示例
这里是 Codepen，因为我认为 SO 需要 allow-same-origin，因此打破了 sn-p。
// Initialize zurb foundation
$(document).foundation();
$(function() {
var grid = $('.grid-stack').data('gridstack');
var options = {
cellHeight: 40,
verticalMargin: 28,
animate: false,
};
// Initialize grid-stack widgets
widgetsInit = function(options) {
$('.grid-stack').gridstack(options);
getWidgetData(); // Find and set positions from local storage
}
updateVisibleWidgetHeights = function(options) {
var targetPanel = '.tabs-panel.is-active';
$(targetPanel + ' .grid-stack .grid-stack-item').each(function(i){
$(targetPanel + ' .grid-stack').data('gridstack').resize(
$(targetPanel + ' .grid-stack .grid-stack-item')[i],
$($(targetPanel + ' .grid-stack .grid-stack-item')[i]).attr('data-gs-width'),
Math.ceil(($(targetPanel + ' .grid-stack .grid-stack-item .grid-stack-item-content')[i].scrollHeight + $(targetPanel + ' .grid-stack').data('gridstack').opts.verticalMargin) / ($(targetPanel + ' .grid-stack').data('gridstack').cellHeight() + $(targetPanel + ' .grid-stack').data('gridstack').opts.verticalMargin))
);
});
}
updateAllWidgetHeights = function(options) {
$('.grid-stack .grid-stack-item').each(function(i){
$('.grid-stack').data('gridstack').resize(
$('.grid-stack .grid-stack-item')[i],
$($('.grid-stack .grid-stack-item')[i]).attr('data-gs-width'),
Math.ceil(($('.grid-stack .grid-stack-item .grid-stack-item-content')[i].scrollHeight + $('.grid-stack').data('gridstack').opts.verticalMargin) / ($('.grid-stack').data('gridstack').cellHeight() + $('.grid-stack').data('gridstack').opts.verticalMargin))
);
});
}
getWidgetData = function() {
// // Load from local storage
var serialization = null;
if (serialization = localStorage.getItem("grid-layout")) {
_.each(JSON.parse(serialization), function (node) {
// Update each widget's properties from values in storage
$('.grid-stack-item[data-custom-id='+ node.id +']').attr({
'data-gs-x': node.x,
'data-gs-y': node.y,
'data-gs-width': node.width,
'data-gs-height': node.height,
});
});
} else {
console.log("There was no local storage data to read")
}
}
widgetsInit(options);
updateVisibleWidgetHeights();
$('.grid-stack').on('change', function (event, items) {
// Save data to local storage
var res = _.map($('.grid-stack .grid-stack-item'), function (el) {
el = $(el);
node = el.data('_gridstack_node');
return {
// Grab widget properties
id: el.attr('data-custom-id'),
x: node.x,
y: node.y,
width: node.width,
height: node.height
};
});
localStorage.setItem("grid-layout", JSON.stringify(res))
});
// On tab change update widget heights to the height of the content they contain
$(document).on('change.zf.tabs', function() {
updateVisibleWidgetHeights();
})
});.grid-stack > .grid-stack-item > .grid-stack-item-content {
