com_Ajax - send POST Request

Question

I am new to JavaScript. I'm creating my module. I'm trying to send data from an html form. I Can not use com_ajax...I create new class in helper.php.

public static function getAjax() {

    jimport('joomla.application.module.helper');
    $input  = JFactory::getApplication()->input;
    $module = JModuleHelper::getModule('mymodulename');
    $params = new JRegistry();
    $params->loadString($module->params);
}

I need to send data to default.php.

I wrote a script to send data to a mod_name.php. JS HERE:

<script>
 jQuery.noConflict();
   function function1() {
    var data = jQuery("lol").serialize();
    jQuery.ajax({
        url: "index.php?option=com_ajax&module=auction&method=post&format=json", 
        type: "POST",
        data: data, 
        success: function(data){ 
            alert(data); 
        }
    });
};
</script>

FOR

<form method="post" action="this.form.submit();" name="form1" id="lol">
    <input type="text" name="price" onclick="function1();">
</form>

Did I do the right thing? And how can I get data in default.php?

Answer 1

The problem is in your url, the correct is:

jQuery.ajax({
        url: "index.php?option=com_ajax&module=auction&method=FUNCTIONNAME&format=json", 
        type: "POST",
        data: data, 
        success: function(data){ 
            alert(data); 
        }
    });

in your case, the FUNCTIONNAME will be get.

And your function, in helper of module, must end with "Ajax". Ex.

public myFunctionAjax(){
  //Do something
}

in this case, url will be index.php?option=com_ajax&module=MODULENAME&method=myFunction&format=json.
