javascript - Get CSS path from Dom element -


i got function csspath :

var csspath = function (el) {   var path = [];    while (     (el.nodename.tolowercase() != 'html') &&      (el = el.parentnode) &&     path.unshift(el.nodename.tolowercase() +        (el.id ? '#' + el.id : '') +        (el.classname ? '.' + el.classname.replace(/\s+/g, ".") : ''))   );   return path.join(" > "); } console.log(csspath(document.getelementsbytagname('a')[123]));

but got : 

html > body > div#div-id > div.site > div.clearfix > ul.choices > li

but totally right, should :

html > body > div#div-id > div.site:nth-child(1) > div.clearfix > ul.choices > li:nth-child(5)

did have idea implement in javascript ?

to right element, need use :nth-child() or :nth-of-type() selectors not uniquely identify element. try this:

var csspath = function(el) {     if (!(el instanceof element)) return;     var path = [];     while (el.nodetype === node.element_node) {         var selector = el.nodename.tolowercase();         if (el.id) {             selector += '#' + el.id;         } else {             var sib = el, nth = 1;             while (sib.nodetype === node.element_node && (sib = sib.previoussibling) && nth++);             selector += ":nth-child("+nth+")";         }         path.unshift(selector);         el = el.parentnode;     }     return path.join(" > "); }

you add routine check unique elements in corresponding context (like title, base, caption, etc.).
