Just to make sure I understand you, You are trying to pass a variable from javascript to CodeIgniter's controller function, right? 为了确保我理解您,您正在尝试将javascript中的变量传递给CodeIgniter的控制器函数,对吗?
If that's your case(hopefully it is), then you can use AJAX, or craft an anchor link. 如果您的情况如此(希望如此),则可以使用AJAX或制作锚链接。
First of all, you're going to use the URI class , specifically the segment()
function. 首先,您将使用URI类 ,特别是
segment()
函数。
Let's assume this is your controller: 假设这是您的控制器:
class MyController extends CI_Controller
{
function input(){
$parameter = $this->uri->segment(3);//assuming this function is accessable through MyController/input
$this->load->helper('form');
$this->load->helper('html');
$this->load->model('mod_user');
$this->mod_user->insertdata();
}
}
Now with javascript you can either craft an anchor tag, or use AJAX: 现在,使用javascript可以制作锚标记或使用AJAX:
Method 1: By crafting an anchor tag: 方法1:通过制作锚标记:
<a href="" id="anchortag">Click me to send some data to MyController/input</a>
<script>
var $rowCount=0;
function invest() {
$rowCount=$('#ulinvestment').find('.rowInvestment').length;
}
$('#anchortag').prop('href', "localhost/index.php/MyController/input/"+$rowCount);
</script>
Method 2: By using AJAX: 方法2:通过使用AJAX:
var $rowCount=0;
function invest() {
$rowCount=$('#ulinvestment').find('.rowInvestment').length;
}
//Send AJAX get request(you can send post requests too)
$.get('localhost/index.php/MyController/input/'+$rowCount);
