Converting String to DOM

My Ajax functions gives me HTML-开发者_JAVA百科Elements as String back, and this String I want to append in my Document as DOM Element.

Something like

parentNode.appendChild(responseText);

What will be the best way to do this.

parentNode.innerHTML += responseText;

you can use innerText to do it

There can be more possible cases. You should clarify a bit.

1. If you get a string that should be an object and it's not existing yet, then you should use this: var tempObj = document.createElement("yourString"); then you can just use tempObj to handle it.

2. If you get a string that is the name or ID of an existing object, then use: var tempObj = document.getElementByName("yourString");

or

var tempObj = document.getElementById("yourString"); 

You can use the DOM methods this library provides, for example the insert() or update() method:

$('parentId').insert(yourString);

or

$('parentId').update(yourString);

http://api.prototypejs.org/dom/element/insert/

http://api.prototypejs.org/dom/element/update/

Note that innerHTML is not standarized yet, so using prototype, you can be sure those methods are cross browser compatible.

Good luck!
