OffsetHeight For Various FontSizes And Be Able To Reduce The OffsetHeight

Jul 23, 2005

My program has divs that contain a single text node. I programatically set the myDiv.style.fontSize = "8pt"; When I call myDiv.offsetHeight, the number "14" is returned. I would like to be able to both predict the offsetHeight for various fontSizes and be able to reduce the offsetHeight.

OffsetHeight - Get The Height Of A <div> Tag

Sep 16, 2007

I'm trying to get the height of a <div> tag so I can use it as a reference in a function to change image height, but I can't seem to get it.

function getdimensions()
{
RightContent = document.getElementById("Right").offsetHeight;
LeftContent = document.getElementById("Left").offsetHeight;
return LeftContent, RightContent;
}
window.onload = function() {
getdimensions();}

I have that, and the div tags have the corresponding ID's, but when I try one of these html buttons to test I just get 'undefined'.

<button onclick="alert(RightContent.offsetHeight);">Right Height</button><br>
<button onclick="alert(LeftContent.offsetHeight);">Left Height</button>

What's going wrong?

Offsetheight Displays 0 In IE

Nov 14, 2007

i've got a .net page with a table sitting in it that has no specified height.
I want to be able to grab the height of a specific table (ID="printIntro"). Firefox spits out a number, but IE regardless of version spits out a big fat 0.

from what i understood, IE should be able to understand offsetheight, no?
here's a snippet of a VERY simplified version of what .net generates, as you will see IE will return 0: Code:

I've got an IFRAME it loads a page with variable contents. I need to know the WIDTH of the body of that page. I'm using offsetWidth and offsetHeight

Quote:

This is weird....offsetHeight returns the height of the document body. offsetWidth returns the width of the iframe!

JQuery :: For Looping To Reduce Code

Sep 22, 2009

I have 5 buttons all using the same code:
$(".but1").mouseenter(function(){
$(".but1>.launch").animate({ left: "10px"}, 250 );
});
$(".but1").mouseleave(function(){
$(".but1>.launch").animate({ left: "0px"}, 250 );
});
$(".but2").mouseenter(function(){
$(".but2>.launch").animate({ left: "10px"}, 250 );
});
$(".but2").mouseleave(function(){
$(".but2>.launch").animate({ left: "0px"}, 250 );
});
$(".but3").mouseenter(function(){
$(".but3>.launch").animate({ left: "10px"}, 250 );
});
$(".but3").mouseleave(function(){
$(".but3>.launch").animate({ left: "0px"}, 250 );
});
$(".but4").mouseenter(function(){
$(".but4>.launch").animate({ left: "10px"}, 250 );
});
$(".but4").mouseleave(function(){
$(".but4>.launch").animate({ left: "0px"}, 250 );
});
$(".but5").mouseenter(function(){
$(".but5>.launch").animate({ left: "10px"}, 250 );
});
$(".but5").mouseleave(function(){
$(".but5>.launch").animate({ left: "0px"}, 250 );
});
Is there a way to do this in fewer lines of code?

JS Reduce - Implement A Function Called Map

Jan 3, 2011

I need to implement a function called map (it needs to be written using reduce) in the below code that takes an array (arr) and a function (iter) as its arguments and returns an array with all its items transformed by iter, e.g. map([1, 2, 3, 4, 5], function(x) {return x * 2;}) should return [2, 4, 6, 8, 10]

JQuery :: Combining Script To Reduce Load Time?

Aug 14, 2010

I found out that (after an system update?) IE8 no longer loads the content on my website www.beautifullalaland.com. I guess it has to do with the ridiculous amount of jQuery calls that some of the simple functions requir. using JS for years but never a library (and never again if you ask me, what a bloody mess).

Is there a safe way to combine jquery_002.js, jquery.js, jquery_003.js and jquery-1.3.2.js?
