Pair of functionalities to String object. Actully i found that
String.toElement method conflicts with Element.update or may be also
with some other functions
Object.extend(String.prototype, {
/**
* If the string is html code and enclosed with html element convert
to Element
* else the string is wraped with <span> or with 1st argument tag
*
* return {Element}
*/
toElement: function() {
str = this.strip();
if (!str.startsWith('<') || !str.endsWith('>')){
wrapTag = arguments[0]||'span';
str = '<' + wrapTag + '>' + str + '</' + wrapTag + '>';
}
var node = new Element('span');
node.innerHTML = str;
if (node.childElements().length == 1) {
return node.down();
}
return node;
},
/**
* Extract elements from HTML code with given selector
*
* @param {String} selector
* @return {Array} Array of elements
*/
extractElements: function(selector) {
return this.toElement().select(selector);
}
})
