插件描述：一款简单且高度可定制的jQuery瀑布流网格布局插件。通过该瀑布流网格插件你可以动态添加和删除各种尺寸的图片，定义图片宽度，设置网格的列数，或使用流式布局方式，甚至还可以通过URL动态添加图片。
使用该瀑布流布局插件之前要先引入jQuery和stackgrid.adem.js文件。
HTML结构
该瀑布流网格布局插件使用的是嵌套
初始化插件
在确保所有内容都被加载之后，可以通过下面的方法来初始化该瀑布流网格布局插件。一定要确保所有的内容都被加载，这样可以使stackgrid计算出正确的高度。// Create a stackgrid object.
var stackgrid = new $.stackgrid;
var options = {
column_width: 320
};
// Wrap the initializer inside window on load to
// make sure to wait until all the grid contents are loaded.
var $window = $(window);
$window.on('load', function(){
// Initialize stackgrid!
// The first two arguments are for the container selector and the item selector.
stackgrid.initialize('#grid-container', '.grid-item', options);
});
添加新的网格
该瀑布流网格布局插件允许你动态的添加新的网格。并且这个过程不需要重新绘制所有的网格。// Create new grid-item.
item = $("
// Append it to the grid-container.
item.appendTo("#grid-container");
// *** If the new content has image(s), make sure it's loaded first before appending!
// Append to stackgrid!
stackgrid.append(item);
重新排列网格// Restack the grid to apply your config changes.
stackgrid.config.is_fluid = false;
stackgrid.restack();
// Certain changes require you to reset the grid.
// These are changes that affect the dimensions of the grid-item or
// if you remove any of the items.
stackgrid.config.column_width = 400;
stackgrid.reset();
stackgrid.restack();
配置参数
下面是该瀑布流网格布局的可用配置参数。// The values shown here are the default ones.
stackgrid.config = {
// Your column width.
column_width: 320,
// Adjust spacing in-between grid-items.
gutter: 20,
// Set this as true to let stackgrid automatically
// determine the number of columns based on the
// viewport's width.
is_fluid: true,
// Set this as true to sort the grid in an vertically optimal way.
is_optimized: true,
// If is_fluid is false, it will
// use this as the default number of columns.
number_of_columns: 4,
// Timeout delay to call the resize complete function.
resize_delay: 300,
// You can customize when and how each item is moved!
// Make sure to use jQuery stop() function if you decide to
// animate it.
// Where you place the callback determines
// when the next move operation is called.
move: function(element, left, top, callback) {
element.css({
left: left,
top: top
)};
callback();
},
// This function is used to scale the container containing
// the grid-items.
// The callback function starts the move operations.
scale: function(element, width, height, callback) {
element.css({
height: height,
width: width
});
callback();
}
};
column_width：网格的宽度。
gutter：网格之间的间距。
is_fluid：是否设置为流式布局。流式布局会使网格自适应页面视区宽度。
is_optimized：该选项设置为true可以使垂直的网格优化排序。
number_of_columns：如果is_fluid选项设置为flase，则使用该选项的值为默认的网格列数。
resize_delay：改变尺寸后的延迟时间。
move：自定义什么时候以及如何移动网格。
scale：该函数用于缩放保存网格的容器。
