Here is the sample HTML and Javascript code:


<script language="javascript">
    function showOrHide() 
    {
        var div = document.getElementById("showOrHideDiv");
        if (div.style.display == "block") 
        {
            div.style.display = "none";
        }
        else 
        {
            div.style.display = "block";
        }
    } 
</script>
 
<a href="javascript:showOrHide();">show/hide</a>
<div id="showOrHideDiv" style="display: none"><h4>Hello</h4></div>

When user click SHOW/HIDE link javascript showOrHide() function is called

Method showOrHide() checks the value of the display style for the div showOrHideDiv

If the display style of div is none (div is not visible) function will set div style to block - so the div will become visible

If the display style of div is block (div is visible) function will set div style to none - so the div will be hidden

<script language="javascript">
    function showOrHide() 
    {
        var div = document.getElementById("showOrHideDiv");
        if (div.style.display == "block") 
        {
            div.style.display = "none";
        }
        else 
        {
            div.style.display = "block";
        }
    }

</script>
<br/>
<a href="javascript:showOrHide();"><b>SHOW/HIDE</b></a> <-- press here
<br/><br/>
<div id="showOrHideDiv" style="display: none">
First name: <input type="text" name="FirstName" value="Donald" /><br />

</script>
 

    <table style="width: 28%; height: 54px;">
        <tr>
            <td>
                <a href="javascript:divHideShow('divA');">hide DivA</a>
                </td>
            <td>
                <a href="javascript:divHideShow('divB');">hide DivB</a></td>
        </tr>
        <tr>
            <td>
                <div id="divA" style="display: block"><h4>Div A</h4></div></td>
            <td>
                <div id="divB" style="display: block"><h4>Div B</h4></div></td>
