Create Pre-styled/populated DOM Elements

  • submit to reddit
 * create a new DOM element with (optionally) specified className, CSS and text/html content
 * if text contains any markup, it's used as innerHTML value - else a child text node is attached
 * if there's also a parent node given, the new element will be appended as child node
function createStyledElement(tag, parent, cls, css, txt) {
    var el = document.createElement(tag);
    if(cls) el.className = cls;
    if(css) for(var s in css)[s]=css[s];
    if(txt) {
        if (txt.indexOf('<')!=-1) el.innerHTML=txt;
        else el.appendChild(document.createTextNode(txt));
    if(parent) parent.appendChild(el);
    return el;

// usage example...
// 1st define some style params
var style1={
    background: '#def',
    color: '#f00',
    padding: '0.5em',
    border: '1px black dotted'

  'hello <em>world</em>!'

Convenient function! I'd only make the test for HTML more rigorous and escape '<' and '>' so this can be used in a bookmarklet: if (txt.match(/\u003C\S+.*\u003E/)) el.innerHTML = txt;
