Ajax JsonRPC从REST-API获取数据

Question

我正在使用odoo 10，它使用的是ribsjs。我在使用带有ajax.jsonRpc的setInterval函数来反复调用rest api并接收数字权重值。

我当前的代码是：

var loopid = setInterval(function () {
                      ajax.jsonRpc('/pos/weight/bridge','process_weight_data',{'input_data':0}).then(function (data) {
                        var weightage_bridge=0;
                          weightage_bridge=data['ibos_weight'];
                          document.getElementById('wrdr').value = weightage_bridge;
                        console.log('Ajax Json RPC Weight POPUP: ' + weightage_bridge);
                        clearInterval(loopid);
                    },function (err) {
                        console.log('dave err: ' + err);
                        clearInterval(loopid);
                    });
            },200)

我的要求是改用setTimeout。如何使用setTimeout重写上面的代码，如下例所示，但使用ajax.jsonRpc（）：

var interval = 1000;  // 1000 = 1 second, 3000 = 3 seconds
function doAjax() {
    $.ajax({
            type: 'POST',
            url: 'increment.php',
            data: $(this).serialize(),
            dataType: 'json',
            success: function (data) {
                    $('#hidden').val(data);// first set the value     
            },
            complete: function (data) {
                    // Schedule the next
                    setTimeout(doAjax, interval);
            }
    });
}

我的完整javascript文件如下：

odoo.define('ibos_pos_weighbridge.weigh_bridge_popups',function (require) {
    "use strict";

    var PosBaseWidget = require('point_of_sale.BaseWidget');
    var gui = require('point_of_sale.gui');
    var _t = require('web.core')._t;
    var ajax = require('web.ajax');

    var IbosPopupWidget = PosBaseWidget.extend({
        template: 'PopupWidget',
        init: function (parent, args) {
            this._super(parent, args);
            this.options = {};
        },
        events: {
            'click .button.cancel': 'click_cancel',
            'click .button.confirm': 'click_confirm',
            'click .selection-item': 'click_item',
            'click .input-button': 'click_numpad',
            'click .mode-button': 'click_numpad',
        },

        // show the popup !
        show: function (options) {
            if (this.$el) {
                this.$el.removeClass('oe_hidden');
            }

            if (typeof options === 'string') {
                this.options = {title: options};
            } else {
                this.options = options || {};
            }

            this.renderElement();

            // popups block the barcode reader ...
            if (this.pos.barcode_reader) {
                this.pos.barcode_reader.save_callbacks();
                this.pos.barcode_reader.reset_action_callbacks();
            }
        },

        // called before hide, when a popup is closed.
        // extend this if you want a custom action when the
        // popup is closed.
        close: function () {
            if (this.pos.barcode_reader) {
                this.pos.barcode_reader.restore_callbacks();
            }
        },

        // hides the popup. keep in mind that this is called in
        // the initialization pass of the pos instantiation,
        // so you don't want to do anything fancy in here
        hide: function () {
            if (this.$el) {
                this.$el.addClass('oe_hidden');
            }
        },

        // what happens when we click cancel
        // ( it should close the popup and do nothing )
        click_cancel: function () {
            this.gui.close_popup();
            if (this.options.cancel) {
                this.options.cancel.call(this);
            }
        },

        // what happens when we confirm the action
        click_confirm: function () {
            this.gui.close_popup();
            if (this.options.confirm) {
                this.options.confirm.call(this);
            }
        },

        // Since Widget does not support extending the events declaration
        // we declared them all in the top class.
        click_item: function () {
        },
        click_numad: function () {
        },
    });
    gui.define_popup({name: 'alert', widget: IbosPopupWidget});

    var IbosWeightReaderPopupWidget = IbosPopupWidget.extend({
        template: 'IbosWeightReaderPopupWidget',
        show: function (options) {
            options = options || {};
            this._super(options);

            this.renderElement();
            this.$('input,textarea').attr('disabled',true);
            var loopid = setInterval(function () {
                      ajax.jsonRpc('/pos/weight/bridge','process_weight_data',{'input_data':0}).then(function (data) {
                        var weightage_bridge=0;
                          weightage_bridge=data['ibos_weight'];
                          document.getElementById('wrdr').value = weightage_bridge;
                        console.log('Ajax Json RPC Weight POPUP: ' + weightage_bridge);
                        clearInterval(loopid);
                    },function (err) {
                        console.log('dave err: ' + err);
                        clearInterval(loopid);
                    });
            },200)
            this.$('input,textarea').focus();
        },
        click_confirm: function () {
            var value = this.$('input,textarea').val();
            this.gui.close_popup();
            if (this.options.confirm) {
                this.options.confirm.call(this, value);
            }
        },
    });
    gui.define_popup({name: 'ibosweightreader', widget: IbosWeightReaderPopupWidget});

});

请使用ajax.jsonRpc （包括 complete：function（）

），通过setTimeout而不是setInterval协助实现 loopid（）函数
