javascript - Gridster 没有在我想要的地方添加小部件

Question

我有以下代码，当我将小部件正确添加到 (1,1) 时可以正常工作，但是当我将 (row, col) 用作 (2,2) 时，它会将小部件添加到 (1,2)。我做错了什么？

gridster = $(".gridster ul").gridster({widget_selector: "li", widget_margins: [5, 5], widget_base_dimensions: [120, 40], min_cols: 0, min_rows: 0, max_size_x: false, avoid_overlapped_widgets: true}).data('gridster');

gridster.add_widget('<li><div>'+docItem.description+'</div><div>'+docItem.vals+'</div></li>', 1, 1, docItem.col, docItem.row);

生成的 HTML 如下...

<div class="gridster ready">
    <ul id="gridData" style="width: 260px; position: relative; height: 50px;">
        <li data-col="1" data-row="1" data-sizex="1" data-sizey="1" class="gs-w" style="display: list-item;"><div>Total</div><div>1</div></li>
        <li data-col="2" data-row="1" data-sizex="1" data-sizey="1" class="gs-w" style="display: list-item;"><div>John</div><div>2</div></li>
    </ul>
</div>

我想检查一下 gridster 是否可以在任何我想要的地方添加一个小部件，而不是以线性增量模式。

编辑:功能正常，完整示例如下。

客户端/myCell.js

Template.cellular.created= function() {
Session.set('idxX',0);
Session.set('idxY',0);
Session.set('gridInit', 0);
currentFileId = "someId";
console.log("Setting file id");

Meteor.call('setFileId', currentFileId, function() {
    console.log("published");
    if(Session.get('gridInit') == 0) {
        gridster = $(".gridster ul").gridster({widget_selector: "li", widget_margins: [5, 5], widget_base_dimensions: [120, 40], min_cols: 0, min_rows: 0, max_size_x: false, avoid_overlapped_widgets: true}).data('gridster');
        Session.set('gridInit',1);
    }
    Meteor.subscribe("myCells"+currentFileId, function() {
                    cells = cellItems.find({owner: 1, myFileId: currentFileId}).fetch();
                    console.log(cells);

                    cells.forEach(function(docItem, idx){

                        console.log("inserting = " +idx + " item.row = "+docItem.row + " item.col = " + docItem.col);
                        //Blaze.renderWithData(Template.cells, docItem, $('#data').get(0));
                        gridster.add_widget('<li><div>'+docItem.description+'</div><div>'+docItem.vals+'</div></li>', 1, 1, docItem.col, docItem.row);
                });
            });
});
};

Template.cellular.events({

        Session.set('gridInit',1);
    }

    Session.set('idxX', Session.get('idxX') + 1);
    Session.set('idxY', Session.get('idxY') + 1);
    var idxX = Session.get('idxX');
    var idxY = Session.get('idxY');
    console.log("Adding new cell to cell list ");

    if($('.newCellDesc').text().trim() != '' && $('.newCellVal').text().trim() != '' && $('.newCellFormula').text().trim() != '') {

        Meteor.call('insertCell', "someId", {owner: 1, myFileId: currentFileId, description: $('.newCellDesc').text().trim(), vals: $('.newCellVal').text().trim(), formula: $('.newCellFormula').text().trim(), col: idxX, row: idxY}, function() {

            console.log("updating gridster with data");
            Meteor.subscribe("myCells"+currentFileId, function() {
                    cells = cellItems.find({owner: 1, myFileId: currentFileId}).fetch();        
                    console.log(cells);

                    cells.forEach(function(docItem, idx){

                        console.log("inserting = " +idx + " item.row = "+docItem.row + " item.col = " + docItem.col);
                        //Blaze.renderWithData(Template.cells, docItem, $('#data').get(0));
                        el = '<li><div>'+docItem.description+'</div><div>'+docItem.vals+'</div></li>'
                        gridster.add_widget(el, 1, 1, docItem.col, docItem.row);
                });

这是一个 much-requested Gridster 的功能，但好消息是 a fix for it在 fork 中可用。

老ducksboard repo的 Gridster 已经休眠了一年多，但其他维护者已经介入合并最近的贡献。 强烈推荐the dsmorse fork of Gridster ，并在我自己的项目中使用了它(并对其进行了微小的修复，与这个问题无关)。

这是 main demo & download page对于 dsmorse fork 。

在其他功能改进中，此分支有一个选项 shift_widgets_up: false 可防止小部件吸附到网格中最上方的可用位置。玩the demo这一点，看起来它可能不是完全没有错误，但这是我所知道的最接近你所问的事情。
