为每个gridster.js小部件设置最小宽度和高度

Question

我正在使用gridster.js与Jquery UI相结合,通过使用此位拖动来使其可调整大小:

$('.layout_block').resizable({
    grid: [grid_size + (grid_margin * 2), grid_size + (grid_margin * 2)],
    animate: false,
    minWidth: grid_size,
    minHeight: grid_size,
    containment: '#layouts_grid ul',
    autoHide: true,
    stop: function(event, ui) {
        var resized = $(this);
        setTimeout(function() {
            resizeBlock(resized);
        }, 300);
    }
});

$('.ui-resizable-handle').hover(function() {
    layout.disable();
}, function() {

    layout.enable();
});

function resizeBlock(elmObj) {

    var elmObj = $(elmObj);
    var w = elmObj.width() - grid_size;
    var h = elmObj.height() - grid_size;

    for (var grid_w = 1; w > 0; w -= (grid_size + (grid_margin * 2))) {

        grid_w++;
    }

    for (var grid_h = 1; h > 0; h -= (grid_size + (grid_margin * 2))) {

        grid_h++;
    }

    layout.resize_widget(elmObj, grid_w, grid_h);
}

正如GitHub上所建议的那样:

我需要为每个小部件指定最小宽度和高度,而不是为gridster指定.

有没有明显的方法来实现这个功能？

谢谢

如果它对任何人有帮助,我设法解决了:

为每个小部件添加了一个数据属性,以指定最小X和Y:

data-minx="2" data-miny="2" 

然后重写了resize函数:

$('.layout_block').resizable({
    grid: [grid_size + (grid_margin * 2), grid_size + (grid_margin * 2)],
    animate: false,
    containment: '#layouts_grid ul',
    autoHide: true,
    start: function(event, ui) {
        var resized = $(this);
        $('.layout_block').resizable( "option", "minWidth", resized.data('minx') * grid_size );
        $('.layout_block').resizable( "option", "minHeight", resized.data('miny') * grid_size );
    },
    stop: function(event, ui) {
        var resized = $(this);
        setTimeout(function() {
            resizeBlock(resized);   
        }, 300);
    }
});

我没有设置最小高度和宽度,而是在可调整大小的启动时运行一个函数

获取minx和miny属性并调整参数以相应地调整大小.
