javascript - Button that makes textarea text bold -


i have button has onclick="bold()" , supposed changing font weight normal bold , normal. isn't doing though. need change or add? here jsfiddle if helps: http://jsfiddle.net/dzvfh/

<script>     var x = document.getelementbyid('description-box');     function bold() {       if( $(x).css("font-weight") == "normal") {         $(x).css("font-weight"), "bold");       }       else {         $(x).css("font-weight", "normal");       }     }   </script>

there syntax error in code:

change

$(x).css("font-weight"), "bold");

to

$(x).css("font-weight", "bold");

full function

function bold() {     var x = $('#description-box');     if (x.css("font-weight") !== "bold") {         x.css("font-weight", "bold");     } else {         x.css("font-weight", "normal");     } }

working fiddle: http://jsfiddle.net/dzvfh/3/

there number of problems in original fiddle.

  • jquery not being included

  • the function defined inside domready - means isn't visible when clicking button

  • the css block had syntax error. style being closed ) instead of }

  • you trying assign element x before dom ready. new fiddle inside function (by time dom ready)
