Create node from markup string

Question

Is there a way to convert markup string to node object in JavaScript? Actually I am looking for the subsitute for:

document.getElementById(\"divOne\").innerH         


        

Answer 1

There's not an existing cross-browser function for this. The following method can be used to achieve the desired effect (using a DocumentFragment for an optimized performance, based on this answer):

function appendStringAsNodes(element, html) {
    var frag = document.createDocumentFragment(),
        tmp = document.createElement('body'), child;
    tmp.innerHTML = html;
    // Append elements in a loop to a DocumentFragment, so that the browser does
    // not re-render the document for each node
    while (child = tmp.firstChild) {
        frag.appendChild(child);
    }
    element.appendChild(frag); // Now, append all elements at once
    frag = tmp = null;
}

Usage (indention for readability):

appendStringAsNodes(
    document.getElementById("divOne"),
   ""
);
