javascript 用于在模型上执行CRUD操作的自定义URL

Posted 2021-05-04

var Books = Backbone.Collection.extend({
	// Lets create function which will return the custom URL based on the method type
    getCustomUrl: function (method) {
        switch (method) {
            case 'read':
                return 'http://localhost:3000/api/Books/' + this.id;
                break;
            case 'create':
                return 'http://localhost:3000/api/Books';
                break;
            case 'update':
                return 'http://localhost:3000/api/Books/' + this.id;
                break;
            case 'delete':
                return 'http://localhost:3000/api/Books/' + this.id;
                break;
        }
    },

    // Now lets override the sync function to use our custom URLs
    sync: function (method, model, options) {
        options || (options = {});
        options.url = this.getCustomUrl(method.toLowerCase());
        
        // Lets notify backbone to use our URLs and do follow default course
        return Backbone.sync.apply(this, arguments);
    }
});
