jquery - 使用客户端验证生成 Openerp 二维码

我想根据字段卷号生成一个二维码,并使用 JavaScript 文件(客户端验证)将其显示在 ID 名为“vyas_qrcode”的 div 容器中。

  1. 生成二维码的逻辑在js文件(qrcode_js.js)里面的start: function()里面,this.$el.append()。在 chromes 控制台中输入时,附加内的代码可以工作,但在此文件中显示错误,提示“<”意外。

  2. 我尝试将此逻辑直接放入 xml 中,但它甚至在加载页面和 dom 之前就加载,因此生成了 qrcode,但值为空。

  3. 我知道我应该将它放在“start: function() ”中,它指的是正在加载的页面和 DOM,但不确定如何从那里开始。

    <
  4. 我还想知道如何验证字段“名称”并使其包含 5 到 10 个字符,并且不应包含符号。我不想从 python 文件中执行此操作,而是从客户端执行此操作,无论是在“init: function()”还是“start: function()”中。

  5. 感谢大家抽出宝贵的时间来帮助我。

我创建的 3 个文件是,

from osv import osv,fields

class qrcode_clientside(osv.osv):

_name = 'qrcode.clientside' # Name of the table.

_columns = {

'name': fields.char("Name", size=64, requried=True), # Name of the person. The name should be between 5 and 10 characters and must not contain symbols . How to do this with the javascript file(qrcode_js.js)
'roll_number': fields.integer("Roll Number", required=True), # Roll number of the person.
}

然后是xml文件qrcode_js.xml

    <?xml version="1.0" encoding="utf-8" ?>
<openerp>
<data>

<record model="ir.actions.act_window" id="action_qrcode_clientside">
<field name="name">QRCode Generation</field>
<field name="res_model">qrcode.clientside</field>
<field name="view_type">form</field>
<field name="view_mode">tree,form</field>
</record>

<menuitem name="QR Code JS" id="qrcode_js_menu" sequence="10" />
<menuitem name="QR Code Side Menu" id="qrcode_js_sidemenu" parent="qrcode_js_menu" sequence="3" />
<menuitem name="QR Code Generator" id="qrcode_js_finalmenu" parent="qrcode_js_sidemenu" sequence="4" action="action_qrcode_clientside" />

<record model="ir.ui.view" id="view_qrcode_clientside_form" >
<field name="name">qrcode.clientside Form View</field>
<field name="model">qrcode.clientside</field>
<field name="arch" type="xml">
<form string="QRCode Clientside Generation" version="7.0">
<sheet>
<group>
<group>
<field name="name" /> <!-- The name should be between 5 and 10 characters and must not contain symbols . How to do this with the javascript file(qrcode_js.js).-->
<field name="roll_number" class="roll_number_class" />
</group>
<group>
<div id="vyas_qrcode" width="100" height="75" > <!-- This is where the QR Code should be generated. It should have the value of the Roll number of the person. -->
QR Code Placeholder
</div>
</group>
</group>
</sheet>
</form>
</field>
</record>


<record model="ir.ui.view" id="view_qrcode_clientside_tree" >
<field name="name">qrcode.clientside Tree View</field>
<field name="model">qrcode.clientside</field>
<field name="arch" type="xml">
<field name="name" />
<field name="roll_number" />
</field>
</record>


</data>
</openerp>

然后是 Javascript 文件 qrcode_js.js 。

openerp.js_qrcode_vyas = function(instance){

instance.js_qrcode_vyas = {};

alert("Inside the main function ");

instance.js_qrcode_vyas.qrcode_clientside = instance.web.Widget.extend({

init: function(parent, name){
console.log("qrcode_clientside page has been loaded.");
},

start: function(){
this.$el.append('
<script type="text/javascript" src="js_qrcode_vyas/static/src/js/jquery.qrcode.min.js"></script>
<script>
$(document).ready(function(){
rollnumber_from_field = $(".roll_no_class").text(); // Getting the value of Roll Number from the roll_number field.
qroptions = { width: 40,height: 40, text:rollnumber_from_field , size: 100, render:"image" }; // To pass arguments to get the QR code.
setTimeout(function(){$("#vyas_qrcode").qrcode(qroptions);}, 4000); // Generating the QR code and displaying it after a delay of 4 seconds.
});

</script>
');

},
});
};

最佳答案

您不需要附加 javascript 标签,您应该能够执行以下操作:

start: function(){
rollnumber_from_field = this.val(); // Getting the value of Roll Number from the roll_number field.
qroptions = { width: 40,height: 40, text:rollnumber_from_field , size: 100, render:"image" }; // To pass arguments to get the QR code.
setTimeout(function(){$("#vyas_qrcode").qrcode(qroptions);}, 4000); // Generating the QR code and displaying it after a delay of 4 seconds.
});
...

(我没有测试过)。看看其他一些小部件。或者看教程:http://odoo-80.readthedocs.org/en/latest/howtos/web.html#widgets-basics

此外,请确保您的 vyas_qrcode.js 文件包含在您的 __openerp__.py 文件中。
