ExtJS 4验证码表格 [英] ExtJS 4 recaptcha form
问题描述
我已经设置了一个密钥，并且可以使该Recaptcha自动显示在页面上，但是我不知道如何将其转换为表单.
I have set up a key and can get the recaptcha to show on the page it self but I don't know how to get it into a form.
实际上我不想使用id，因为稍后我也会在应用程序内部重用它，因此最好使用itemId.我假设尚未创建该元素.
Actually I don't want to use an id since I'll be reusing this later inside the app too so to use itemId would be preferred.I'm assuming that the element hasn't been created yet.
我的包括: HTML代码:
My include: HTML Code:
<script type="text/javascript" src="http://www.google.com/recaptcha/api/js/recaptcha_ajax.js"></script>
错误(从recaptcha_ajax.js生成.无法获取ID为'recaptcha'的控件): 未被捕获的TypeError:无法将属性'innerHTML'设置为null
Error (generated from recaptcha_ajax.js. Can't get the control with id 'recaptcha'): Uncaught TypeError: Cannot set property 'innerHTML' of null
代码如下:
Ext.define('Login.view.Login', {
extend: 'Ext.form.Panel',
alias: 'widget.Login.view.Login',
border: false,
bodyPadding: 5,
initComponent: function() {
var config = {
layout: 'anchor',
defaultType: 'textfield',
defaults: {
anchor: '100%',
allowBlank: false
},
items: [{
fieldLabel: 'Company Id',
name: 'companyId'
},{
fieldLabel: 'Username',
name: 'username'
},{
fieldLabel: 'Password',
name: 'password',
inputType: 'password'
},{
/*xtype: 'panel',
itemId: 'reCaptcha',
border: false,*/
html: '<div id="recaptcha">adsf</div>'
}],
buttons: [{
text: 'Login'
}]
};
Ext.apply(this, config);
this.callParent();
},
afterRender: function() {
Recaptcha.create("heres_my_public_key",
document.getElementById('recaptcha'),
{
theme: "clean"/*,
callback: Recaptcha.focus_response_field*/
}
);
this.callParent();
}
});
有人使用ExtJS 4做到了吗?
Anyone done this using ExtJS 4?

验证码创建得太早了.解决方案:
captcha created too early. Solution:
