I am trying to use javascript to make text bold. I have searched the net and it seems that I can do a document.write() after I made my string bold. Isn't there any way to perform this without opening any new page (in the same html text area)?
function bold()
{
document.write(selectedText.bold());
}
Edit: I am implementing an Text Editor and I am using a HTML TextArea, and I am trying to add all the functionality such as bold, italic, etc. I want to be able to select part of the text written and make it bold.
// method 1: direct write out something with bold tags
document.write('<b>My Bold Text</b>');
// method 2: add an element styled to be bold
var span = document.createElement('span');
span.innerHTML = 'My Bold Text';
span.style.fontWeight = 'bold';
document.getElementsByTagName('body')[0].appendChild(span);
// method 3: add an element classed to be bold
// add style sheet first:
// <style type="text/css">.bold { font-weight: bold; }</style>
// then the jS:
var span = document.createElement('span');
span.innerHTML = 'createElement.className - My Bold Text';
span.className = 'bold';
document.getElementsByTagName('body')[0].appendChild(span);
Something like that? Otherwise, please be more specific with your question.
Do you want to set an existing element to bold? If this is the case, set font-width
CSS property to bold
. Try this:
document.getElementById("myTextId").style.fontWeight = "bold";
or, if you are using jQuery,
$('#myTextId').css("font-weight", "bold");
Update: HTML <textarea>
tag does not support separate styling of different parts of its content; you can't make a rich text editor this way.
