用php显示div元素的JQuery

Question

The problem is when I press left-nav "a" element it should show() me the div element, but its going to hide() it automatically. The "a" element is created with php and it has href of ?id=$product , when I press class closebtn "a" element in side my navbar it show() 's me the div.

JavaScript:

$(document).ready( function() {
    $(".sisu").hide();
    $('.vasaknav a').click( function() {
        $(".sisu").show();
    });
});

PHP:

<?php
    $kask=$yhendus->prepare("SELECT id,Product from store GROUP BY Product");
    $kask->bind_result($id, $Product);
    $kask->execute();

    while($kask->fetch()){
        echo "<a href='?id=$Product' style='color:red;'>".htmlspecialchars($Product)."</a>";
    }
?>

HTML:

<div id="Myvasaknav" class="vasaknav">
    <a href="javascript:void(0)" class="closebtn" onclick="closeNav()">&times;</a>
    <?php require('php/navlist.php'); ?>
    <a href=#  >test</a>
</div>

<span style="font-size:30px;cursor:pointer" onclick="openNav()" id="click">&#9776;</span>

Answer 1

To prevent default action when clicking <a> (which is reloading page / redirecting elsewhere) you should change your code like:

$(document).ready( function() {
    $(".sisu").hide();
    $('.vasaknav a').click( function() {
        $(".sisu").show();
        return false;   // prevent default action
    });
});

With this you will stay on the same page and .sisu element will be shown.
