PHP code

<?php
    $page = isset($_POST['page']) ? intval($_POST['page']) : 1;
    $rows = isset($_POST['rows']) ? intval($_POST['rows']) : 10;
    $offset = ($page-1)*$rows;

    $result = array();

    include "conn.php";

    $rs = mysql_query("select count(*) from users");
    $row = mysql_fetch_row($rs);

    var_dump($row);

    $result["total"] = $row[0];
    $rs = mysql_query("select * from users limit $offset,$rows");

    $items = array();
    while($row = mysql_fetch_object($rs)){
        array_push($items, $row);
    }
    $result["rows"] = $items;

    echo json_encode($result);

?>

It must be syntax error, but without the source code it is impossible to inform anything.

What is this eval of the result in success?

– Woss

2017/10/03 at 23:23
@Andersoncarloswoss fixed: were the var_dumps in php code!!

– alexjosesilva

2017/10/03 at 23:24
Yet this eval doesn’t make sense.

– Woss

Your problem is the lack of a comma before success: function(result){ within the function saveUser().

As the error itself states: "Uncaught Syntaxerror" (syntax error), is the lack of a separator (in this case, a comma) in the function instances saveUser() before success:.

function saveUser(){
    $('#fm').form('submit',{
        url: url,
        onSubmit: function(){
            return $(this).form('validate');
        }
        // falta uma vírgula aqui
        success: function(result){
            var result = eval('('+result+')');
            if (result.errorMsg){
                $.messager.show({
                    title: 'Error',
                    msg: result.errorMsg
                });
            } else {
                $('#dlg').dialog('close');      // close the dialog
                $('#dg').datagrid('reload');    // reload the user data
            }
        }
    });
}
