Meaning Of SetTimeout()'s Return Value
Dec 31, 2009I'm troubleshooting some issues with menus closing and when I alert the return value from something like:
timer = setTimeout("closeMenu(id)",500);
I get 2,3,4. It seems to increment. Does that just represent how many times the timeout code has been executed?

Use Return Key To Submit
Jan 17, 2007I have a form on a web page that requires to click on a button to
submit the information. I have two questions about changing this form:
1. Is there a way that I can change the script so that the form can be
submitted by hitting the enter key?
2. Is there a way that I can have the Username and Password boxes
cleard after the form is submitted?
You probably don't need the code for the form as it is pretty basic but
here it is just in case.
<form name=login>
<table width=225 border=1 cellpadding=3>
<tr><td colspan=2><center><font size="+2"><b>Bombers Only
Area!</b></font></center></td></tr>
<tr><td>Username:</td><td><input type=text name=username></td></tr>
<tr><td>Password:</td><td><input type=password name=password
size="20"></td></tr>
<tr><td colspan=2 align=center><input type=button value="Login!"
onClick="Login()"></td></tr>
</table>
</form>
Return Says NaN (Not A Number)?
Aug 1, 2009i am using ajax but this is the problem in js it is giving me a NaN when i goto check the output. on two different servers two different responses on my localhost test environment i am getting the correct info and on the server online i get NaN response. i am using this to set the width of my hp bar
Code:
document.getElementById("ehpBar").style.width=count1+"%";
and count1 looks like this
Code:
var count1 = hp/basehp*100;
i have tried rounding it and everything and i just get the same stupid NaN error. I can use each variable by itself and it outputs the correct number on both servers and then when i try to divide it NaN on one server and works perfectly on the other. I know it is probably something simple i am just missing it.

Function Will Not Return Value
Aug 21, 2007I am populating a field on my page using a php include. I am asking javascript to update another element with that field's value. The value written to the select input box is Ƈ:Any Provider'. The process works fine in Firefox. In IE6 it does not write. the value nor does it throw an error. What am I doing wrong?
input form:
[PHP]<form method="post" action="" name="inputForm">
<label for="provider">Name of Provider</label><select class="input" name="provider" size="1" style="width: 20em"><?php nameprov();?></select>
<input type="button" name="button" value="Upload" onclick="postthis()">
<div id="status"></div>
</form>
The script in the head element:
function postthis(){
var provider = document.inputForm['provider'].value;
var report = document.getElementById("status");
var message="The Value of Provider Block is: " + provider;
report.innerHTML = message;
}
In firefox, "The Value of Provider Block is: 1:Any Provider" is written in the report element. In IE6, "The Value of Provider Block is : " is written in the report element.

Feb 27, 2006I'm having a problem. I was able to get the edit working fine. I was able to get it to hide the current div and go to a different div. When I combine the two, the edit works but I cannot go to the different div.
I'm thinking something is missing here?

return formCheck(this);
document.getElementById('startDiv').style.display = 'none'

Functions With A Return Value
Apr 29, 2004PHP Code:
function mnu() {
var thismenu=this;
var mDiv = document.createElement("div");
mDiv.getVisibility=function() { thismenu.getVisibility(this); }
alert(mDiv.getVisibility());
document.body.appendChild(mDiv);
}
mnu.prototype.getVisibility=function(div) {
if (div.style.visibility=='none' || div.style.visibility=='hidden') {
return 'hidden'
}
else {
return 'visible'
}
}
so i attach a function to mDiv, which (should) return visible or hidden, but it doesn't, i get an undefined
but when i put alert boxes in the function itself (in the if-clause), it gives me the correct values....

Return Match Using Regex
May 18, 2007I have been working on this for a few hours and am frustrated
beyond all extent. I have tried to research this on the web as well
with no success. I am trying to match certain contents within a
wrapper div. So for example if the inside of the wrapper div was the
following:
<div id="wrapper">
<a href="#">a great link that contain text and symbols</a>
<div... </div>
<div... </div>
</div>
I would like to strip out all the internal div's. But because there
can be alot of internal div's, I figured it would be less processor
intensive to just match the first 'a' tag and repopulate the wrapper
div with the match. I am trying to use something like the following
regex:
re = /^<a(.+)</a>/;
with the following statment:
$temp = document.getElementById('wrapper').innerHTML.match (re);
but this is returning the entire contents of the wrapper div. I have
tried variations of the regex and either continue to get the entire
contents or null returns. Any help would greatly be appreciated.
BTW, I can't match to the first because the contents may be touching (ie ...</a><div>...).
How To Allow CARRIAGE RETURN And BACKSPACE?
