从javascript调用控制器方法 [英] Calling controller method from javascript

问题描述

我需要从Javascript中调用名为 test（）的控制器方法。脚本代码如下：

I need to call a method of controller named test() from a Javascript. Script code is given below:

function changeColor(id, color) 
{
    element = document.getElementById(id);
    qnid = document.form1.pickupFrom.qnid;

    //window.location =  "<?= site_url('controller/test') ?>"
}

有可能吗？以及如何传递参数？

Is it possible? And how to pass the parameters?

推荐答案

这取决于您需要传递的参数。它们是PHP参数吗？你做得很好，或者更好地看@Sudhir回答。

It depends on what parameters youn need to pass. Are they PHP parameters? The you're doing just fine, or better see @Sudhir answer.

如果你的params来自javascript你就不能使用 site_url（ ）函数（因为当它详细阐述并吐出url时，javascript尚未执行）。以这种方式构建URL会容易得多：

If your params come from javascript you shoulnd't use the site_url() function (since when it elaborates and spit out the url, javascript is yet to be executed). It would be much easier to build a URL this way:

function changeColor(id, color) {
            element = document.getElementById(id);
            qnid = document.form1.pickupFrom.qnid;

            window.location =  "<?php echo base_url();?>index.php/controller/test/"+element+"/"+qnid;
}

我假设这两个是您要传递的参数。

I'm assuming those two are the parameters you want to pass.
