JavaScript function arguments statements -


my problem is: (only example, must not make sense overall):

// make function , pass part of statement argument function examplefunction( argument ) {     document.getelementbyid('testid')[0].style.argument = '#f00'; }  // later onload examplefunction( background );

i found out doesn't work way, can't find out how right. if correct example send me on way happy , thankful.

firstly document.getelementbyid returns single element (or null if no element found), not [0]. secondly if want reference property dynamically use [] notation

// make function , pass part of statement argument function examplefunction( argument ) {     document.getelementbyid('testid').style[argument] = '#f00'; }  // later onload examplefunction( 'background' );
