Question

我试图在按钮点击时调用一个函数，但由于某种原因按钮不会调用该函数。 Dreamweaver不显示任何语法错误。任何人都可以告诉我为什么按钮不起作用？

        function moveRight(){

           animate = setTimeout(moveRight(), 1000); 
           imgObj1.style.left = parseInt(imgObj1.style.left = 0) + Math.floor((Math.random() * 100) + 1) + 'px';

           animate1 = setTimeout(moveRight(), 1000);

不幸的是，有很多错误，很难知道从哪里开始。你的问题的第一个答案是按钮什么也没做，因为你的代码没有编译。我不知道为什么Dreamweaver没有报告错误。 Chrome的开发人员工具非常乐意这样做。

这是＆＃34;工作＆＃34;版本：

while ($row = mysql_fetch_array($res_final)) {
    if($row[5]== 's') {
        $row4_info = "";

        if (($row[4]== 'y')&& ($row[5]!= 's')) {
            $row4_info = "<input type='text' id='".{$row[0]}."' class='A{$count}' value=''>";
        }

        $row5_info = "";

        if ($row[5]== 's') {
            $row5_info = "<input type='text' id='".{$row[0]}."' class='A{$count}' value='' disabled='disabled'>";
        }

        echo "<tr> <td>". $sn = $startpoint + $count . "</td>
              <td class='C{$count}'>"  .$row[0] ."</td>
              <td >" . $row[1] . "</td>
              <td>" . $row[2] . "</td>
              <td>" . $row[3] . "</td>
              <td class='warning'>" . $row[4] . "</td>
              <td class='warning'>" . $row[5] . "</td>
              <td>" .$row4_info.$row5_info."</td></tr>";
    } 
    else {
        echo "<tr><td>" . $sn = $startpoint + $count . 
              "</td><td class='C{$count}'>"  .$row[0] ."</td>
              <td>" . $row[1] . "</td>
              <td>" . $row[2] . "</td>
              <td>" . $row[3] . "</td>
              <td>" . $row[4] . "</td>
              <td>" . $row[5] . "</td>
              <td>" . "<input type='text' id='{$row[0]}'
              class='A{$count}' value=''  />" . "</td></tr>";
    }

    $count = $count +1;
}

按钮未正确调用功能
