Items List

Javascript can remember a list of several items you enter. Just enter an item and click 'Add to List'. When you are finished, click 'Show List' to see the entries.


Insert into <HEAD>


Insert into <BODY>
<CENTER> <FORM name="history"> <INPUT name="command" type="text" value=""> <INPUT type="button" value="Add to List" onclick="f_store(document.history.command.value)"> <INPUT name="history" type="button" value="Show List" onclick="f_print()"> </FORM> <P> <SCRIPT language="JavaScript"> <!-- hide it ... function MakeArray( n ) { if( n <= 0 ) { this.length = 0; return this; } this.length = n; for( var i = 1; i <= n; i++ ) { this[ i ] = 0; } return this; } var history = new MakeArray( 15 ); var index = 0; var cmmnd = 1; function f_store( sTR ) { var i; if( index >= history.length ) { for( i = 1; i < history.length; i++ ) history[i-1] = history[i]; index = history.length - 1; } history[ index ] = cmmnd + ":" + sTR; ++cmmnd; ++index; document.history.command.value=""; } function f_print() { var allCmmnds, i; allCmmnds = ""; for( i = 0; i < index; i++ ) allCmmnds += history[i] + "\n"; alert( allCmmnds ); } // End --> </SCRIPT>
