Example of getting started with JavaScript sup method (displaying strings as superscripts), javascriptsup
The sup method returns the supermark string defined using the HTML sup tag attribute. The syntax is as follows:
Copy codeThe Code is as follows:
Str_object.sup ()
Tip: This method does not comply with the ECMA standard and is not recommended.
Sup method example:
Copy codeThe Code is as follows:
<Script language = "JavaScript">
Document. write ('helping home' + 'Every progress is a solid footprint on our road to success'. sup ());
</Script>
Run this example and output:
Copy codeThe Code is as follows:
Every progress made by the customer's house is a solid footprint on the road to success.
Tip: This method returns the supermark string defined using the HTML sup tag. That is, the string cannot be changed to the supermark style directly by using this method. If you want to dynamically change the element font to an upper style, refer to the following example:
Change the font text upper/lower alignment mode (superscript/subscript)
Copy codeThe Code is as follows:
<Html>
<Script language = "JavaScript">
Function changFont (x ){
Document. getElementById ("sub_title"). style. verticalAlign = x;
}
</Script>
<Body>
<P>
<A onClick = "changFont ('sub ');"> subscript style </a> <a onClick = "changFont ('super');"> superscript style </a>
</P>
<P>
<Span id = "sub_title"> every progress is a solid footprint on the road to success </span>
</P>
</Body>
</Html>
In this example, JavaScript controls the text CSS vertical-align style to dynamically change the upper and lower alignment of the font text (superscript/subscript ).
