Hi, I am new to jQuery and is curious if this code can be shortened down? It feels like it can, but I couldn't find any way to use jQuery selectors if I have a specific reference to a object.
What I want to do is to find the element to the parent of "el" that the id starts with linecolorbox. I know how to do it if I want to find ALL the ones that id start with linecolorbox, but not if I want to start with a specific element as reference (el.parentNode). jQ('.linecolor').each( function() { try { var el = this; if(el.value.match(/^f{6}$/i)) { el.value = ''; } var nodes = el.parentNode.childNodes; for(var i=0; i<nodes.length; i++) { for(var j=0; j<nodes[i].childNodes.length; j++) { if(nodes[i].childNodes[j].id) { if(nodes[i].childNodes[j].id.match(/^linecolorbox/)) { var colorbox = nodes[i].childNodes[j]; if(el.value.match(/^[0-9a-f]{6}$/i)) { colorbox.innerHTML = ' '; } else { colorbox.innerHTML = ' X '; } } } } } } catch(e) { alert(e.message); } } );
