单击一个按钮以更改文本输入的文本

Question

I have this part of code in the Codeigniter controller named 'ajaxcalls' :

public function show_contact_persons($client_id) {
        $data['contact_persons'] = $this->common_model->select_records('ci_contact_persons', 'client_id', $client_id);
        //dump($data);

    function echoArray ($array) {
        foreach ($array as $key => $value)
        {
            if ( true == is_array($value) )
            {
               echoArray($value);
            }
            else
            {
                if ($key == 'contact_person_name') {
                    echo '<input type="button" value="'.$value.'" onclick="changeContact(987)" /><br />';
                }
            }
        }
    }
    echoArray($data);

}

and then the JS part at the page which is calling the PHP file :

function changeContact(contact_name) {
             document.getElementById('contact_person').value = contact_name;
        }

I put the number '987' in this example because the code works only with NUMBERS. When I put text inside the bracket, or what I REALLY want to do :

onclick="changeContact('.$value.')"

then the script doesn't work. ONLY with numbers. What should I change to make it work with strings?

Answer 1

You are very close.

Use this instead :

onclick="changeContact("'.$value.'")"

Whats happening is the JS is rendering it as changeContact(stringValue); so its expecting it to be a defined variable.

Adding the quotations will pass it into the function as a string which will render as : changeContact("stringValue");
