JavaScript strike method

The strike method returns a string of deletes defined using the HTML strike tag attribute. The syntax is as follows:



str_object.strike()

Note: this method does not conform to ECMA standards and is not recommended.

Instance of strike method



<script language="JavaScript">
var str = "www.jb51.net";

document.write( str.strike( "//www.jb51.net" ) );
</script>

Run the example and output:



www.jb51.net

Tip: this method returns a deletes string defined using the HTML strike tag, that is, it does not directly change a string to a string with deletes. If you want to dynamically change the element font to a string with deletes, see the following example:

Add a decorative effect to the font text (strikeout, underlining, overlining, flashing)



<html>

<script language="JavaScript">

function changFont( x ){

    document.getElementById("article").style.textDecoration = x;

}

</script>

<body>

<p>

<a onClick="changFont('none');"> There is no decoration </a> <a onClick="changFont('line-through');"> Delete the line </a>

<a onClick="changFont('underline');"> The underline </a> <a onClick="changFont('overline');"> On the line </a>

</p>

<p id="article">

 I am some words  ...<br />

Some Text ...

</p>

</body>

</html>
