【问题描述】：
我正在使用 BackgridJs，它使用 Backbonejs 用数据填充网格。
这就是我的代码现在的样子：

var Territory = Backbone.Model.extend({});
var Territories = Backbone.Collection.extend({
model: Territory
//url: "examples/territories.json"
});
//var territories = new Territories();
var territory1 = new Territory({ name: "How Bizarre", pop: 20 });
var territory2 = new Territory({ name: "How ", pop: 21 });
var territories = new Territories([territory1,territory2]);
var columns = [{
name: "id", // The key of the model attribute
label: "ID", // The name to display in the header
editable: false, // By default every cell in a column is editable, but *ID* shouldn't be
// Defines a cell type, and ID is displayed as an integer without the ',' separating 1000s.
cell: Backgrid.IntegerCell.extend({
orderSeparator: ''
})
}, {
name: "name",
label: "Name",
// The cell type can be a reference of a Backgrid.Cell subclass, any Backgrid.Cell subclass instances like *id* above, or a string
cell: "string" // This is converted to "StringCell" and a corresponding class in the Backgrid package namespace is looked up
}, {
name: "pop",
label: "Population",
cell: "integer" // An integer cell is a number cell that displays humanized integers
}, {
name: "percentage",
label: "% of World Population",
cell: "number" // A cell type for floating point value, defaults to have a precision 2 decimal numbers
}, {
name: "date",
label: "Date",
cell: "date",
}, {
name: "url",
label: "URL",
cell: "uri" // Renders the value in an HTML anchor element
}];
// Initialize a new Grid instance
var refreshgrid = function(){
var grid = new Backgrid.Grid({
columns: columns,
collection: territories
});
// Render the grid and attach the root to your HTML document
$("#example-1-result").append(grid.render().$el);
}
// Fetch some countries from the url
//territories.fetch({reset: true});
$(".dropdown-menu li").click(function(){
$(this).closest('.btn-group').children('a').text($(this).text())
});
$('#submit').on('click', function(event) {
url = '/ledger/data'
company_code = $("#company_code").text();
// event.preventDefault(); // To prevent following the link (optional)
$.post( url, { name: "John", time: "2pm" },function(data){
ledgerData = JSON.parse(data);
refreshgrid();
});
//$.post(url,function(response){
// alert(response);
//});
});
</script>
</body>
</html>
当我在 Post 请求中获取 JSON 数据时，我无法弄清楚如何在 refreshgrid() 调用期间将其提供给网格。
在大多数 Backbonejs 示例中，url 在模型本身中，但对我来说，每次提交后 url 都会不断变化。那么，如何获取数据并将其提供给网格？
