如何从 PHP 调用 javascript 函数 reset()？

Question

I am trying to call JavaScript reset() function by using button onclick method. The code is embedded in PHP as follows :

<?php    
echo "<form>";
echo "<input type='text' name='keyword'>";
echo "<input type='button' value='Clear' onclick='<script>reset();</script>'>";
echo "</form>";
?>

The clear button is not working.

Answer 1

一种解决方案是将输入按钮行替换为以下内容：

echo "<input type='button' value='Clear' onclick='javascript:reset()'>";

Answer 2

try this:

<?php    
  echo "<form>";
  echo "<input type='text' name='keyword'>";
  echo "<input type='button' value='Clear' onclick='reset()'";
  echo "</form>";

Answer 3

This should work - But i would try to get away from putting event handlers inline like this. Perhaps you could use jquery instead.

Below however is a 'Vanilla javascript" solution as you requested...

<?php 
echo "
    <form>
    <input type='text' name='keyword'>
    <input type='button' value='Clear' onclick='this.parentNode.reset()' >
    </form>
 ";
?>

Answer 4

You can do this if you want :

 <?php    
   echo "<form>";
   echo "<input type='text' name='keyword'>";
   echo " <input type='button' value='Clear' onclick='reset();'>";
   echo "</form>";
?>

Another way to show HTML code in PHP :

Instead of using echo you can just put any HTML or Javascript code in side this ?> HTML | JAVASCRIPT CODE <?PHP ?> HTML | JAVASCRIPT CODE <?PHP

If you want to put PHP code inside that HTML code you can do the normal procedure which is this :

Example :

<?php   
     // Here it can be any PHP code 
    ?>
     <form>
     <input type="hidden" name="<?php echo 'phpinsidehtml';?>"> //This is an example 
     <input type='text' name='keyword'>
     <input type='button' value='Clear' onclick='reset();'>
     </form>
     <?php
    ?>
