Odoo 自定義form表單按鈕點擊事件處理程式

實踐環境

Odoo 14.0-20221212 (Community Edition)

代碼實現

方案1

通過研究發現，點擊odoo form表單按鈕時，會調用odoo14\odoo\addons\web\static\src\js\views\form\form_controller.js文件中的_onButtonClicked函數，在該函數中響應點擊事件。所以，我們可以通過重寫該方法來實現自定義響應點擊事件。示例如下

表單視圖定義

codePojects\odoo14\custom\estate\wizards\demo_wizard_views.xml

<?xml version="1.0" encoding="UTF-8"?>
<odoo>
    <data>
        <record id="demo_wizard_view_form" model="ir.ui.view">
            <field name="name">demo.wizard.form</field>
            <field name="model">demo.wizard</field>
            <field name="arch" type="xml">
                <form>
                    //...代碼略 
                    <footer>
                        <button name="action_confirm" special="other" type="object" string="確認" class="oe_highlight"/>
                        <button string="關閉" class="oe_link" special="cancel"/>
                    </footer>
                </form>
            </field>
        </record>
        //...代碼略        
    </data>
</odoo>

重定義web.FormController以實現重寫_onButtonClicked

codePojects\odoo14/estate/static/src/js/views/form_controller.js

odoo.define('customModule.FormController', function (require) {
    "use strict";

 	var formController = require('web.FormController');
	var CustomFormController = formController.extend({
        //--------------------------------------------------------------------------
        // Handlers
        //--------------------------------------------------------------------------

        /**
         * @private
         * @param {OdooEvent} ev
         */
        _onButtonClicked: function (ev) {
            // stop the event's propagation as a form controller might have other
            // form controllers in its descendants (e.g. in a FormViewDialog)
            ev.stopPropagation();
            var self = this;
            var def;

            this._disableButtons();

            function saveAndExecuteAction () {
                return self.saveRecord(self.handle, {
                    stayInEdit: true,
                }).then(function () {
                    // we need to reget the record to make sure we have changes made
                    // by the basic model, such as the new res_id, if the record is
                    // new.
                    var record = self.model.get(ev.data.record.id);
                    return self._callButtonAction(attrs, record);
                });
            }
            var attrs = ev.data.attrs;
            if (attrs.confirm) {
                def = new Promise(function (resolve, reject) {
                    Dialog.confirm(self, attrs.confirm, {
                        confirm_callback: saveAndExecuteAction,
                    }).on("closed", null, resolve);
                });
            } else if (attrs.special === 'cancel') {
                def = this._callButtonAction(attrs, ev.data.record);
            } else if (attrs.special == 'other') { // 新增自定義事件處理
                self._enableButtons(); // 啟用按鈕(點擊後會自動禁用按鈕)
                self.trigger_up('close_dialog'); // 關閉對話框
                return;
            } else if (!attrs.special || attrs.special === 'save') {
                // save the record but don't switch to readonly mode
                def = saveAndExecuteAction();
            } else {
                console.warn('Unhandled button event', ev);
                return;
            }

            // Kind of hack for FormViewDialog: button on footer should trigger the dialog closing
            // if the `close` attribute is set
            def.then(function () {
                self._enableButtons();
                if (attrs.close) {
                    self.trigger_up('close_dialog');
                }
            }).guardedCatch(this._enableButtons.bind(this));
        },
	});

odoo.__DEBUG__['services']['web.FormController'] = CustomFormController;
});

codePojects\odoo14\custom\estate\views\webclient_templates.xml

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <template id="assets_common" inherit_id="web.assets_common" name="Backend Assets (used in backend interface)">
         <xpath expr="//script[last()]" position="after">
             <script type="text/javascript" src="/estate/static/src/js/views/form_controller.js"></script>
         </xpath>
    </template>
</odoo>

codePojects\odoo14\custom\estate\__manifest__.py

#!/usr/bin/env python
# -*- coding:utf-8 -*-
{
    'name': 'estate',
    'depends': ['base'],
    'data':[
        # ...略
        'views/webclient_templates.xml',
        'wizards/demo_wizard_views.xml',
        # ...略
    ]
}

方案2

研究發現，在不為按鈕設置type屬性的情況下，可以為按鈕添加onclick屬性，指定點擊按鈕時需要調用的javascript函數，不過，此時點擊按鈕，不會再調用web.FormController中定義的_onButtonClicked函數。示例如下：

<?xml version="1.0" encoding="UTF-8"?>
<odoo>
    <data>
        <record id="demo_wizard_view_form" model="ir.ui.view">
            <field name="name">demo.wizard.form</field>
            <field name="model">demo.wizard</field>
            <field name="arch" type="xml">
                <form>
                    //...代碼略 
                    <footer>
                        <button name="action_confirm" do_confirm_action('demo.wizard','action_confirm') string="確認" class="oe_highlight"/>
                        <button string="關閉" class="oe_link" special="cancel"/>
                    </footer>
                </form>
            </field>
        </record>
        //...代碼略        
    </data>
</odoo>

codePojects\odoo14/estate/static/src/js/demo_wizard_views.js

function do_confirm_action(modelName, modelMethod){
    // do something
    //...
    $("button[name='action_confirm']").attr("disabled", true);
}

codePojects\odoo14\custom\estate\views\webclient_templates.xml

<?xml version="1.0" encoding="utf-8"?>
<odoo>
    <template id="assets_common" inherit_id="web.assets_common" name="Backend Assets (used in backend interface)">
         <xpath expr="//script[last()]" position="after">
             <script type="text/javascript" src="/estate/static/src/js/demo_wizard_views.js"></script>
         </xpath>
    </template>
</odoo>
