[RESOLVED] what am I missing? simple function.

**thewebiphyer** · 09-29-2012 09:20 AM

does anyone have any idea why this function doesn't work????

function chck(ans){
var userin = document.getElementById(ans).value;
if (userin == ans) {
alert("correct!");
}
}

html (written as part of a javascript function):
<form action=\"chck(' "+letters+" ')\"><input type=\"text\" id=\""+letters+"\" value=\"answer here (no caps)\"/>\
<input type=\"submit\"></form>

I would say it's the added spaces here:

Code:

(' "+letters+" ')\

cf:

Code:

('"+letters+"')\

this simplified example seems to work ok:

Code:

<body>
<script type="text/javascript">
var letters="abc"
document.body.innerHTML="<form><input type='text' id="+letters+" value='answer here (no caps)'/><input type='button' value='check' onclick=\"chck('"+letters+"')\"/></form>";
function chck(ans){
var userin = document.getElementById(ans).value;
if (userin == ans) {
alert("correct!");
}
}
</script>
</body>

OH MY FREAKIN HECK... wow I can't believe if missed that.. this was just a very small part of a single script 3-400 lines long that I've been working on for weeks... but thank you a million times over for that suggestion... lol i feel dumb now cause I should have noticed that a long time ago... I do have one question, though... why are single quotes not required around the double quotes in the id="+letters+" part? I kept them in originally because I thought that that it would be required to follow HTML syntax.
