Rounding Returned Value From Jquery.css

Sep 7, 2011

So just found out the problem I was having, and came up with a solution (bandaid really) but would like to know if anyone else has run into this and what they did.

Code JavaScript:
var left_margin = $(this).css('margin-left').replace(/D/g,'');

So the above, get the left margin of the object, strip all but numbers and store into a variable. Easy, right? Here's what happened. Inserted the object into the DOM, Chrome returned 212px, which was converted to 212�*fine. Firefox on the other hand returned 212.5px, which was converted to 2125� not fine. I'm centering the element on the screen based on this number, so the additional 2000ish pixels is WAY off. My solution was to increase one of my initial values a single pixel in which both browsers return 213px�*but like I said this is only a bandaid solution. Not really understanding the value of .5 pixel, but looking into that. Is there a rounding function in jquery? Javascript I would have to strip the px from the string, convert to integer and THEN round.

JQuery :: State Of The Art For Corner Rounding?

May 1, 2009

I have a half dozen bookmarks for rounded corner plugins, but am wondering if there's a "state of the art" plugin kicking any booty on that these days? What I'd *really* like is to just be able to set -moz border radiuses in CSS and have a plugin magically use those to create rounded corners in IE and Safari (IE mainly... using excanvas or something with it is fine, too).

Rounding ...

Nov 9, 2003

I have to round a fractional value from a form input to either 0, 25, 50 or 75. I have succesfully tested the value and stripped the decimal place. If the value is for example .1, I round it to 0. If the value is say .2, I round it to .25. My problem is that when the value is > .75, my function is returning undefined. For the sake of brevity I will include only the relevant code.

var increments = new Array(0,25,50,75);

CharBefore = parseFloat(CharBefore); //the whole number
CharAfter = parseFloat(CharAfter); //the decimal

var x = parseFloat(increments.length - 1) ;

for ( i = 0; i <= x ; i++ ) {

var testValue = parseFloat(increments[i]);
if (CharAfter > testValue) { continue ; }
else {
var lowerValue = parseFloat(increments[i-1]);
if ((CharAfter > testValue) && (i==x)) {

median = (testValue + 100)/2 ;
if (CharAfter >= median) {
CharAfter = Ɔ'
CharBefore++;} //round up to next whole number
else { CharAfter = testValue; }

}
else {
median = (testValue + lowerValue)/2 ;
if (CharAfter >= median) { CharAfter = testValue; }
else { CharAfter = lowerValue; }

}
return CharBefore + '.' + CharAfter;
break;

}

} // End for loop

Rounding Figure And Have Only 3 Digits After Decimal Points

Nov 8, 2009

Suppose I do (5 * 0.039) + 0.59, then the result is 0.7849999999999999 - but I want to round it upwards and should have only 3 digits after decimal point. I found out that using toFixed(3) will get it to be 0.785, but the problem is that it add x.x00 for some numbers where there aren't much decimal numbers. Is there a way I can remove the 0's?

JQuery :: Use Data Returned In $.get()

Jul 19, 2011

Here is the code I am running:

The url is a very straightforward servlet that queries a database and returns either Y or N. That part is working fine. The first alert shows Y or N just as it is supposed to.

However, the second alert is always showing Turbo, as though the if statement is not able to compare properly. This is probably javascript rather than specific to jQuery, but can anyone see where I'm going wrong?

JQuery :: Animate Ajax Returned Data ?

Jul 8, 2010

$.ajax({

So I'm loading the div#my_events by prepend(data) where "data" is another well styled div. Is there anyway to animate this returned data. Unfortunately I can't just specify a unique ID on the incoming data. So I was wondering how else I might be able to address this data I'm returning.

It is basically a topic list, with a modal that sends jquery to add a topic to the database, and returns the topic from the database, hides the modal, and displays the last added topic at the top of the topic list. Now I'd like it to do something slightly fancy like animate the color of the background to bring the user's attention to it.

JQuery :: Events On Elements Returned Using Ajax?

Oct 7, 2010

I define a "click" event on "a" tags in the ready part of a page. It fires just fine when I click on any "a" tag on the page. I then have a button which sets the content of a div using ajax. This content contains a couple of "a" tags. The issue now is that the "click" event does NOT fire when clicking on these tags. I suspect it is because they did not exist when the page was initially rendered. What is the "JQuery way" of dealing with an issue like this? Of course I cannot be the only one in the world who needs to return HTML with events from my ajax calls :-)

JQuery :: Extracting Data Being Returned From PHP Script?

Jul 5, 2009

Here is what I'm trying to do. I will pass a directory to a PHP script, that script will then return an array of filenames back to the javascript that called it. In the javascript I want to take the filenames returned and create links to them in an unordered list.

The PHP code to get the filenames is done and when I run the script I get an array that I have formatted into json... an example of the encoded array is as follows...

{"filename:["file01.jpg","file02.jpg","file03.jpg","file04.jpg","file05.jpg","file06.jpg"]};

So here is the jquery I'm trying to use to get the filenames and create my links... But I must be missing something because my variable... data ... is empty... but status is Success.

JQuery :: Ajax Returned Data Format ?

Sep 23, 2009

Getting information from a php file. Basically :

MY JAVASCRIPT FILE:

In this dumb example, I'm unable to match the 'data' returned variable with the value I assigned to it in php (I can't manage to enter my 'do stuff'), yet its value is 'ok' if I display it. I have no problem to retrieve html code from php and inject it in my pages, but I can't test it as a regular javascript string.

What's wrong in this ? What have I missed about the 'data' format ? Do I have to 'cast' data to a javascript string (and if so, how ?)

JQuery :: Last Line Of Returned Rows Not Colored

May 13, 2009

I have a function that is calling a list of events. Within the <code>.each</code> is alternating row colors code (see below):

function DisplayEventList(info,event_id){
$.post('/url/server.php',{
request:info,
event_id:event_id
},
function(xml){
$('#event-listing tbody').empty();
$(xml).find('list').each(function(){
var startdate = $("start",this).text(); .....

My problem is that the last line of my returned rows isn't coloring. If 14 rows return, the first 13 will alternate coloring, but the 14th will not. Consequently, if only 1 line is returned, it does not color.
