| Why do people use XMLHttpRequest when creating a new script object and appending it to the body in some cases seems so much natural? |
| I don't understand what you're asking |
| What i'm asking is what's the for/against on using XmlHttpRequest versus something like var script = document.createElement("script"); script.src = "somefile.js.php?info=abc&param=xyz"; document.body.appendChild(script); |
| You can't do that, for one. Security mechanisms prevent it |
| Why not? No they don't I've done it |
| Because that would open up a huge can of cannibalistic worms Okay, show me. |
| Erm. where? |
| Wherever you did it |
| On my private intranet... |
| Ha |
| Ha what? I'm not making this up |
| Ha you're full of shit. Yes you can do that, yes you can set whatever attributes yo uwant But it won't work It won't parse the script |
| Yes, it does, on IE and FF. and i'll back up that claim if you give me a moment. This page details what i just said: http://www.webreference.com/programming/ajax_tech/ Huh, well.. it has been working fine for me. given that, is it better/worse than other methods? |
| I was thinking oScript.innerHTML = "blah blah blah" You can't do innerHTML on a script element. My bad. |
| Okay That's ok. so anyway, seems to me that a lot of time you want to kick of some javascript after you get your data, so why not do it this way, where the JS file returns the data plus a statement or two that gets the page updated? |
| I've never been able to get <script></script> code to parse that comes from an ajax request Ie, updating a div with <script></script> elements |
| This isn't coming from an ajax request if you mean XmlHttpRequest... it's a new script element that requests a file with parameters, on the server side some language like PHP could generate the javascript for the request Do you get my meaning |
| So what issues is it giving you? |
| No issue, i was just wondering why it doesn't seem more widely used since it seems like a pretty good technique for me. maybe there's something i'm not aware about Anyway it works for me and it seems standards compliant so i think i'll employ it when appropriate By default it'll block if you are doing it on your local machine But it shoudl work on a web site by default afaik |
