Question

我有一张可编辑的表格。下面是一个函数，它给出表，给定要呈现表的元素ID，列数组和控制器名称，用于构造URL。 URL具有以下格式，其中exampleController是示例控制器：

要更新：php / gateway.php？sender = exampleController＆amp; action = update
列表：php / gateway.php？sender = exampleController＆amp; action = list

我希望POST请求包含已编辑的信息以及相应的行。

我尝试在下面的代码中做某事。它发出请求但不包括POST。

var initiateGrid = function(element_id, columns, controllerName) {
    var gridModel = Backbone.Model.extend({

        initialize: function() {
            Backbone.Model.prototype.initialize.apply(this, arguments);
            this.on("change", function(model, options) {
                if (options && options.save === false) {
                    return;
                }
                this.sync();
            });
        },
        sync: function(method, model, options) {
            var methodUpdateMethodUrl = 'php/gateway.php?sender=' + controllerName + '&action=update';
            options = options || {};
            options.url = methodUpdateMethodUrl;
            Backbone.sync(method, model, options);
        }
    });

    var gridCollectionModel = Backbone.Collection.extend({
        model: gridModel,
        url: 'php/gateway.php?sender=' + controllerName + '&action=list',
    });

    var gridCollection = new gridCollectionModel();

    var grid = new Backgrid.Grid({
        columns: columns,
        collection: gridCollection,
        emptyText: "No Data"
    });

    var gridContainer = $("#" + element_id);
    gridContainer.append(grid.render().el);

    gridCollection.fetch({
        reset: true
    });

};

当然，还有这个错误：

尝试更改网址

url:function() { return 'php/gateway.php?sender=' + controllerName + '&action=list', }

以下代码对我有用：

set @site := 1 ;
set @language := 3  ;

select
language_id,paragraph_0 from (
  select language_id,paragraph_0 from tablename where site_id =@site and language_id = @language
  union 
  select language_id,paragraph_0 from tablename where site_id =@site and language_id = 2
  union 
  select language_id,paragraph_0 from tablename where site_id =@site and language_id = 1
)x
order by language_id desc limit 1;

用PHP获取数组：

var initiateGrid = function(element_id, columns, controllerName) {

    var gridModel = Backbone.Model.extend({

        initialize: function() {
            Backbone.Model.prototype.initialize.apply(this, arguments);
            this.on("change", function(model, options) {
                this.sync("update", model, options);
            });
        },
        sync: function(method, model, options) {
            var methodUrl = {
                'update': 'php/gateway.php?sender=' + controllerName + '&action=update'
            };
            console.log(method, model, options);
            if (methodUrl && methodUrl[method.toLowerCase()]) {
                options = options || {};
                options.url = methodUrl[method.toLowerCase()];
            }
            Backbone.sync(method, model, options);
        }
    });

    var gridCollectionModel = Backbone.Collection.extend({
        model: gridModel,
        url: 'php/gateway.php?sender=' + controllerName + '&action=list',
    });

    var gridCollection = new gridCollectionModel();

    var grid = new Backgrid.Grid({
        columns: columns,
        collection: gridCollection,
        emptyText: "No Data"
    });

    var gridContainer = $("#" + element_id);
    gridContainer.append(grid.render().el);

    gridCollection.fetch({
        reset: true
    });

};
