Shortening The Show/hide Script?

May 28, 2010

I have a simple hide/show script that is doing what I want, but I was wondering if there is an easier way around having to specify show and hide requirements "onclick" each time. Here is what I've got:

Javascript:

<script type="text/javascript">
function show(boxid) {
document.getElementById(boxid).style.display="block";
}

Optimizing String Shortening Algorithm?

Aug 16, 2010

I've written a function that "condenses" a string if it is too long.

function shortenMsg(msg,maxLen){
if (msg.length > maxLen){
var over = msg.length - maxLen, // amount that needs to be trimmed

[Code]....

Each of the methods 1-3 is the amount that that specific method can trim from the string. I'd like to be able to trim as little as possible.

For example, if the string needs 5 characters to be trimmed, and method1 can trim 8 characters, but method3 can trim 6, then method3 should be used. If none of the methods can individually trim the string enough, then I'd like the optimal combination of the methods that will get the job done.

I can't figure out what sort of code structure I need for this (besides a ton of if/else statements). Maybe an array that contains each of the methods, arranged in increasing order....?

JQuery :: $("selector" - Code) And .html() - Load Div In A Variable - Modify It In Another Variable And Then Change The Document Injecting The Contents

Dec 13, 2011

I want to load an html div in a variable, modify it in another variable; and then change the document injecting the contents.

1. I load the html to be changed in a variable (code)
2. I modify an attribute of <param> using attr() and I put the result in a var (newcode)
3. I change the html in the doc

I've used the debugger, and all steps give the expected results, except of newcode.html(), which is a null string. Why?

Can't Get Variable In Code

Feb 15, 2009

When I try to substitute the the number 1 with the variable scr_val it does not work. This works:

Code:

if(document.course.frm_score_front1.value != '' && document.course.frm_score_front1.value > parseInt(num_over))
{document.course.adj_score_front1.value = parseInt(num_over);}else{document.course.adj_score_front1.value = '';}

This does not:

Code:

var ct_val=1;
if(document.course.frm_score_front1.value != '' && document.course.frm_score_front1.value > parseInt(num_over))
{document.course.adj_score_front+ct_val.value = parseInt(num_over);}else{document.course.adj_score_front1.value = '';}

Javascrip Code In Php Variable

Nov 24, 2005

I would like to know if it is possible to insert workable javascript
code into a variable. For example, in php if I say

<? echo $blah; ?> and $blah equals " ?> <script>
top.navi.document.title </script> <?"

I would want the page to act out the code when i tell it to echo the
variable.

If this is not possible, is there a way to set information from
javascript into a php variable?

Also, i would like to know how to use if statements in javascript. For
example, if I have a variable x and i want to see if x equals "test"
and if it does then it caries out some code.

JQuery :: Using DIV ID As Variable For Some Code

Jan 7, 2012

I use 'div id' as a variable for some code I'm working on. The idea is that depending on what 'div' the user clicks on the variable will change as according to the 'div id', as below:
$(document).ready(function(){
$(".box").click(function(e){
var newvar = ("#" + $(this).attr("id") + "Contact");
position();
if(popupStatus==0){
$("#fadedBG").css({
"opacity": "0.5"
});
$("#fadeBG").fadeIn("slow");
$(newvar).fadeIn("slow");
popupStatus = 1;
}});
Now that part of the code is all fine and dandy, however the continued functions, e.g. 'position()', doesn't seem to pick up the newly defined variable.

The rest of the code is outside the brackets of the 'click'-event above, and would look something like:
function position(){
var popH = $(newvar).height();
var popW = $(newvar).width();
...
How come doesn't the continued functions recognize the defined variable 'newvar'? Is it because the code loads as a whole and can not pick up variables later, as when a 'click' event is triggered? Are there ways around this?

Why Certain Variable In Code Remains Undefined

Jul 22, 2011

We are currently re-working a client's website and as I am not a javascript programmer I am having trouble understanding some of the code, and need help understanding why a certain variable in the code remains undefined.

What is happening is that the user is filling in 24 lines of 4 select boxes, in which there must be 1 and only one "m" and 1 and only 1 "l". The code changes the value of the box back to blank if the user has tried to enter >1 of either. The code then should check the line number and count the number of lines, but on debugging I see that the value of variables el and LineNo are undefined. I can't understand why when the function is called, the value "this" is used. i.e CheckLine(this) - this appears to have no value in the html code as far as I can see!

Finding A Code To Get Height Variable?

Mar 23, 2010

I have a iframe element which currently has a small amount of javascript that handles the scrolltop and I am trying to add a variable to that which controls the height of the iframe based on the source height. I do not want to set the height of the iframe in CSS because if I use this same method for other iframes and the source height is not the same it will not work.The page with the iframe is here (click on the link on the top of the page to load the iframe):

[URL]

The page I want to load into the iframe is here:

[URL]

The javascript and html for the parent page is:

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

[code]...

Again, what I need is for the iframe to get the document height from the page that will load into the iframe and then have the iframe height be that exact size. As you can see once you click on the link it is much shorter than the page I am using to load into the iframe.I do not know javascript enough to figure it out and have spent a couple days looking all over the internet and have yet to find something I can incorporate into the javascript I already have.
