I have the following table that lets you edit directly on the grid:

Hercodes:

MySQLtable

CREATETABLEIFNOTEXISTS'php_interview_questions'('id'int(8)NOTNULL,'question'textNOTNULL,'answer'textNOTNULL,'row_order'int(8)NOTNULL)INSERTINTO'php_interview_questions'('id','question','answer','row_order')VALUES(1,'PHParrayfunctionsexample','is_array(),in_array(),array_keys(),array_values()',3),(2,'HowtoredirectusingPHP','Usingheader()function',4),(3,'DifferentiatePHPsize()andcount():','Same.Butcount()ispreferable.',1),(4,'WhatisPHP?','Aserversidescriptinglanguage.',0),(5,'Whatisphp.ini?','PHPconfigurationfile.',2);

DBController:

<?phpclassDBController{private$host="localhost";
    private $user = "root";
    private $password = "";
    private $database = "blog_examples";

    function __construct() {
        $conn = $this->connectDB();
        if(!empty($conn)) {
            $this->selectDB($conn);
        }
    }

    function connectDB() {
        $conn = mysql_connect($this->host,$this->user,$this->password);
        return $conn;
    }

    function selectDB($conn) {
        mysql_select_db($this->database,$conn);
    }

    function runQuery($query) {
        $result = mysql_query($query);
        while($row=mysql_fetch_assoc($result)) {
            $resultset[] = $row;
        }       
        if(!empty($resultset))
            return $resultset;
    }

    function numRows($query) {
        $result  = mysql_query($query);
        $rowcount = mysql_num_rows($result);
        return $rowcount;   
    }
}
?>

index.php

<?php
require_once("dbcontroller.php");
$db_handle = new DBController();
$sql = "SELECT * from php_interview_questions";
$faq = $db_handle->runQuery($sql);
?>

        }

          </tbody>

</html>

saveedit.php

<?php
require_once("dbcontroller.php");
$db_handle = new DBController();
$result = mysql_query("UPDATE php_interview_questions set " . $_POST["column"] . " = '".$_POST["editval"]."' WHERE  id=".$_POST["id"]);
?>

The table is all working perfectly, the only thing I want to change is next, when I edit a value and give ENTER the line breaks down, if I click on the screen somewhere vacant the same saves what was typed , what I want, when I press ENTER happens in the same way as if I click on the screen, my information is saved.

how to load data from a page according to the clicked ID? [closed] How do you do when the user touches the menu symbol appears in the Toast?

Places in TD a onkeydown calling the same parameters as onblur .

onKeyDown="checkEnter(event, this,'question','<?php echo $faq[$k]["id"]; ?>')"

But calling the function below:

function checkEnter(e, editableObj, column, id){
   if (e.keyCode == 13 && e.shiftKey == false) {
      saveToDatabase(editableObj, column, id);
      e.preventDefault();
   }
}
