i have this code
var tmpEl = document.createElement('div')
tmpEl.innerHTML = stringEl;
return tmpEl.firstChild
which i use for converting text to Dom node.
The problem is that if stringEl
contains <tr>
tag i must create table
tag not div
for this to work.Also if want this code to work with stringEl
contaning li
tag i must create ol
or ul
insted of div
tag. Is there any generic for converting string to Dom node?
Best Regards,
Iordan

If you provide different values of your
stringEl
and what you expect at the end, it might be helpful for understanding your problem. – skovalyov Commented Oct 19, 2012 at 13:54 - I think you underestimate the plexity of this problem. This snippet is useful when you deal with the restricted set of elements, but it's way too loose if intended to be generic. Check the related functions of jQuery (.parseHTML, .buildFragment) to see how it's solved there; hint: it's far from 3 lines of code. – raina77ow Commented Oct 19, 2012 at 13:58

Reset to default 3There is a method of DOM Range designed for this: createContextualFragment()
. It's specified in the DOM Parsing and Serialization spec and is implemented Mozilla, WebKit and Opera browsers (but not IE, yet).
Here's an example: http://jsfiddle/gbWCS/
HTML:
<table id="table">
<tr id="firstRow"><td>One</td><td>Two</td></tr>
</table>
JavaScript:
var html = "<tr><td>Three</td><td>Four</td></tr>";
var table = document.getElementById("table");
var range = document.createRange();
range.selectNodeContents(table);
var frag = range.createContextualFragment(html);
table.appendChild(frag);
function domNode(nodeType, text) {
var node = document.createElement(nodetype);
node.appendChild(document.createTextNode(text));
return node;
}
domNode('p', 'Hello World!');
Something like that allows you to choose a tag.
Edit: In fact...
function domNode(nodeType, text) {
var node = document.createElement(nodetype);
if (text) node.appendChild(document.createTextNode(text));
return node;
}
var myList = domNode('ul').appendChild(domNode('li', 'This is a list item!'));
