Image as a Reset ButtonHTML allows you to use an image as a submit button, but it doesn't provide for images as reset buttons. We can work around that limitation, however, with a little JavaScript. The technique described here allows you to easily create a reset image button. This technique only requires you to write a few lines of code.First, copy the following JavaScript exactly as-is into your web page. Don't change anything.
<SCRIPT TYPE="text/javascript"> <!-- // copyright 1999-2001 Idocs, Inc. http://www.idocs.com/tags/ // Distribute this script freely, but keep this // notice with the code. var resetRolls = new Object(); function resetimage(src) { this.src=src; this.confirm=true; this.alt="Reset"; this.write=resetimage_write; } function resetimage_write() { document.write('<A '); if (this.rollover) { if (! this.name) { alert('to create a rollover you must give the image a name'); return; } resetRolls[this.name] = new Object(); resetRolls[this.name].over = new Image(); resetRolls[this.name].over.src=this.rollover; resetRolls[this.name].out = new Image(); resetRolls[this.name].out.src=this.src; document.write( ' onMouseOver="if (document.images)document.images[\'' + this.name + '\'].src=resetRolls[\'' + this.name + '\'].over.src"' + ' onMouseOut="if (document.images)document.images[\'' + this.name + '\'].src=resetRolls[\'' + this.name + '\'].out.src"' ); } document.write(' HREF="javascript:'); if (this.confirm) document.write('if(confirm(\'Are you sure you want to reset?\'))'); document.write( 'document.forms[' + (document.forms.length - 1) + '].reset();void(0);">'); document.write('<IMG SRC="' + this.src + '" ALT="' + this.alt + '"'); document.write(' BORDER=0'); if (this.name)document.write(' NAME="' + this.name + '"'); if (this.height)document.write(' HEIGHT=' + this.height); if (this.width)document.write(' WIDTH=' + this.width); if (this.otheratts)document.write(' '+ this.otheratts); document.write('></A>'); } //--> </SCRIPT>
Now, suppose we want to use this image as our reset button:
<FORM ACTION="../cgi-bin/mycgi.pl"> <INPUT NAME="query"> <INPUT TYPE=IMAGE SRC="go2.gif" HEIGHT=22 WIDTH=50 ALT="go!" BORDER=0> <SCRIPT TYPE="text/javascript"> <!-- var ri = new resetimage("reset.gif"); ri.write(); //--> </SCRIPT> <NOSCRIPT><INPUT TYPE=RESET></NOSCRIPT> </FORM> Which gives us this form: In the previous section we showed you how to create a rollover submit image. In the next page we'll show you how to create a rollover reset image. We'll also explain how to set some of the optional settings. |
