Why does .html work and not innerHTML or appendChild

Question

I am trying to add an ajax response to a div (it's HTML code with tables, forms, etc).

In FF innerHTML works perfectly, but in IE it gives me an unknown error.

I tried lots of stuff, but I only got it working when I added jQuery and ran the .html method on the div I want the code inserted into.

Anyone care to explain why this works and not a simple innerHTML ? I tried looking at the .html() code, but I guess I am not the great at JS because I didn't understand what it was doing.

Answer 1

IE has several documented ( pre | table (thead, tbody, tr, tfoot) | div | select ) .innerHTML bugs .

Thus libraries like jQuery abstract away those bugs for you by applying workarounds where needed for IE.

As for your specific error... without seeing the code it is hard to tell.

Setting the .innerHTML on pre's, certain div's, select's (if it does fail, will fail silently) but setting the .innerHTML on certain table elements (in certain versions of IE) will actually throw an error/exception.

Note : The issue with setting the .innerHTML of a div is very specific in condition and only occurs in IE6 & IE7.

只需使用jQuery，就不必理会所有可怕的跨浏览器问题-您将不会再回头！

Answer 3

IE is fussy about changing <table>s from javascript. I've run into trouble before if I don't specify the table down to the last detail, including the <tbody> tag.

Answer 4

I have same problem every day. Try with .innerText instad of .innerHTML, that will solve your problem. Answer is Javascript is parsed different in IE and FF.
