IE innerHTML error

Question

This is a little different than the questions that have already been asked on this topic. I used that advice to turn a function like this:

function foo() {

You can create your own shim/polyfill of .innerHTML. I have just made some code to fix another problematic aspect of .innerHTML in IE: the clearing of child .innerHTMLs:

You can modify the behavior. Here is some code that prevents garbage collection of otherwise-referenced elements in IE:

if (/(msie|trident)/i.test(navigator.userAgent)) {
 var innerhtml_get = Object.getOwnPropertyDescriptor(HTMLElement.prototype, "innerHTML").get
 var innerhtml_set = Object.getOwnPropertyDescriptor(HTMLElement.prototype, "innerHTML").set
 Object.defineProperty(HTMLElement.prototype, "innerHTML", {
  get: function () {return innerhtml_get.call (this)},
  set: function(new_html) {
   var childNodes = this.childNodes
   for (var curlen = childNodes.length, i = curlen; i > 0; i--) {
    this.removeChild (childNodes[0])
   }
   innerhtml_set.call (this, new_html)
  }
 })
}

var mydiv = document.createElement ('div')
mydiv.innerHTML = "test"
document.body.appendChild (mydiv)

document.body.innerHTML = ""
console.log (mydiv.innerHTML)
