JavaScript代码未使用php codeigniter执行

Question

I am using some used code in my project

The following code is used to add the product in the wishlist written in view

<p class="p"><a<?php  echo "onclick='addtowishlist($product->id)'";  ?>>Add To Wishlist</a></p>

The Javascript code for this

  function addtowishlist(pid) {   remoteCall("cart/addtowishlist/"+pid,"","loadlist"); }
 function loadlist() { alert(sResponse); }

This is my controller naming cart

   public function addtowishlist($pID)
    {

    $data=$this->Product_model->addtowishlist($pID);
    echo $data;

    }

This is my Model naming Product_model

function addtowishlist($ProductID) { echo "Added succesfully";
}

This is my ajax for remote call function used in javascript

enter code herefunction remoteCall(sUrl, sQueryStr, sCalledBy){

uri = sUrl;
callingFunc = sCalledBy;

xmlHttp=GetXmlHttpObject();

if (xmlHttp==null)
{
    alert ("Your browser does not support AJAX!");
    return;
}
if (xmlHttp) 
{
    xmlHttp.onreadystatechange = stateHandler;
    xmlHttp.open("POST", sUrl, true);
    xmlHttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
    xmlHttp.send(sQueryStr);
}   }

I only want to show the message written in my controller to displayed when clicked on the Add to wishlist link

Answer 1

这就是您可以调用该函数的方式

<p class="p"><a onclick="addtowishlist(<?php echo $product->id; ?>)">Add To Wishlist</a></p>

Answer 2

I think the problem is because if the URL, for adding URL to your client side code use site_url() function. change this part:

 function addtowishlist(pid) {   remoteCall("cart/addtowishlist/"+pid,"","loadlist"); }
 function loadlist() { alert(sResponse); }

to:

function addtowishlist(pid) {   remoteCall("<?php echo site_url('cart/addtowishlist/'+pid) ?>","","loadlist"); }
 function loadlist() { alert(sResponse); }

Of course this part of code should be in PHP file to be able to handle the PHP part.

Just for the record the best way for handling these kinds of situation is using JQuery library for AJAX actions and adding the related data to some attribute like data-href or other ones.
