我想要的是,只有从下拉菜单中选择某个选项并且我有一个html表单如下所示,才能访问该文本框:
<tr>
<td>a. Did any of your staff participate in training or orientation sessions related to any aspect of social performance management, during the reporting year? </td>
<td >
<p>
<select name="mfi_4_a_i">
<option>Yes</option>
<option>No</option>
<option>No, but planning in future</option>
</select>
</p>
<p>if not,and not planning please explain why not </p>
<input type="text" name="mfi_4_a_ii" id="sdd" />
</tr>
现在,当用户选择选项No,但将来计划时,必须启用文本框,否则必须禁用文本框.
我该如何做到这一点？
我是codeigniter的新手,我从其中一个教程中尝试了一课,但它引发了以下错误:
Class 'Controller' not found in
C:\xampp\htdocs\CodeIgniter\application\controllers\email.php
on line 3
我的代码:
<?php
class Email extends Controller{
function __construct()
{
parent::Controller();
}
function index()
{
$config = Array(
'protocol' => 'smtp',
'smtp_host' => 'ssl://smtp.googlemail.com',
'smtp_port' => 465,
'username' => 'saveniroj@gmail.com',
'password' => 'password'
);
$this->load->library('email', $config);
$this->email->set_newline("\r\n");
$this->email->from('saveniroj@gmail.com', 'Niroj Shakya');
$this->email->to('saveniroj@gmail.com');
$this->email->subject('This is a test email');
$this->email->message('Oops This is Great.');
if($this->email->send())
{
echo 'Your email was sent, FOOL';
}
else
{
show_error($this->email->print_debugger());
}
}
}
?>
有什么问题？
我有许多文本框只有在完成某些操作时才需要启用,例如从下拉菜单或复选框中选择它.为此,我想在我第一次打开表单时禁用所有文本框.我需要使用一个函数来完成,这个函数只会禁用我想在开始时禁用的文本框.我怎样才能做到这一点？
