javascript - ReferenceError:Something_anything_nothing 未定义

Question

我收到 ReferenceError:something_anything_nothing 未定义错误...请帮助。

    <script>
    function show(str)
    {
    var r=str;
    alert(r);
    }
    </script>


    <?php
    $l='something_nothing_anything';
    echo "<select onChange='show($l)'>";
     echo "<option></option>";
       echo "</select>";
      ?>

Answer 1

$l='Somethin_nothin_anythin'; 
$buffer="<select onchange='show(\'".$l."\')'>"; 
$buffer.= "<option></option>"; 
$buffer.="</select>";
echo $buffer;

试试这个

Answer 2

您可能需要将 $l 中的值用引号括起来，如下所示：

$l='"something_nothing_anything"';
