View 24 RepliesI'm trying to make a beautifull ajax-based fom like javascript galleries. With this I get HTML form, generated by PHP script, depending on passed parameters:
$("#info").load('./handler.php', {object: 'course', action: 'add'});
It works cool, but obtained HTML isn't affected by the script and can't handle any events, for example:
$("form").click(function () {
alert('click is made');
});
doesn't work anyway. I supposed to send data from this form using ajax, e.g. '.load()', but as you see, I can't use script on it.
I'm attempting to make a little slide show navigation box..thing, along the lines of what a lot of sports sites and, say, Gamespot use (digression: do these boxes have a technical name?).
My setup is pretty simple - I have a small PHP script that iterates over an image folder and pulls both the file name and last modified info from each image and stores them in an associative array. The array is json_encode()-ed. My jQuery $.get()'s the json, parses it, and then creates image elements based on the info. Cycle then does its thing and creates the slide show.
It all works, with one problem - the images don't appear upon a first visit to the site. They only appear on subsequent visits. This happens in the big three browsers (IE, FF, Chrome) without fail. A refresh is always necessary.
I'm not sure if it's a runtime issue, a cache issue, or if somehow Cycle isn't 'seeing' the images the first time. Please help. My code is below:

The following code works fine in FF and Chrome for getting a radio selections value but not IE8.
$('input[name="search[gender]"]').change(function()
{
var check = $('input[name="search[gender]"]:checked').val();
Inputs are below:
<input type="radio" name="search[gender]" value="1" class="v_middle" />Male
<input type="radio" name="search[gender]" value="2" class="v_middle" />Female
<input type="radio" name="search[gender]" value="3" class="v_middle" />Couple
<input type="radio" name="search[gender]" value="4" class="v_middle" />tv
<input type="radio" name="search[gender]" value="" checked="checked" class="v_middle" />All
The first time you click a radio button in IE8, no value is returned at all (tested with document.write of the 'check' value), with an error "'null' is null or not an object". The second (and rest of the times) you click any of the checkboxes the wrong value is returned, it returns the value of the currently checked button (which we checked a moment ago) rather than the one we have checked the second time. Does Internet Explorer have issues with this onchange function method? Or is something wrong with my code?
let me try to explain better what I'm trying to do. I'm a real newbie I don't know much javascript but I understand more or less the logic behind it... tell me if this solution should work and if you know how to do it please show me. [URL]... I need to make div#photo's width to match the total width measurement of all the images it contains. If you load the page and you don't touch the size, it will work fine... but that's not realistic. If I resize the page, which will happen often on this kind of page (I'm assuming), the whole thing goes haywire (try it, scroll to the last image and resize the page you'll see what I mean). What can I do? Is my idea the right solution? Am I not explaining this clearly enough? Let me know please, I'm desperate. I've been trying to get CSS to do this for me for 3 hours now. Nothing works.

View 1 Replies View RelatedI currently have a website where i share thoughts with my friends (some kind of forum) and within this 'forum' people can post pictures they made but most of the time these pictures exceed the max width of my website so my website gets all streched out!So this is what i want: all images on the page must run thru some sort of function which checks if the image image width exceeds the max_width. if it does then the script must calculate how many pixels the current width exceeds the max_width and get this number so that the script does: current_width = current_width - (max_width - current_width)
View 1 Replies View RelatedI've recently start using Flexigrid (old JQuery grid plugin), and, as you may know, one of the few issue this really good grid plugin got is the lack of liquid layout option. My personal idea to solve the problem is to set the "width" parameter depending on $(window).width. Here is the problem (and here's why i post this question in "General use" and not in "Plugin").
The starting, and working, code is:
$(document).ready(function(){
$("#flex1").flexigrid

This work fine for me, but I supose it could be done way much elegant... maybe somethin without "IF" that could emulate the "%", like var percentage = $(#div.id).width()*0.XX with the 0.XX picked from an array of percentage, one for each column. Probably I should set up a function... ahhhh, as you may easily see I'm a total beginner with JQuery (and JS in general...)
I am trying to setup a javascript function that sets a div's width based on the combined width of the li's with the name "navItem". The problems I have been running into when trying to define the width of the li's is that they do not have a width defined in css. Can anyone help me out with this? The javascript function setWindow is suppose to show the div loginWindow and set the width of it.
Code:
<div id="topNav">
<ul>
<li><img src="<?php print $site->folder['images']['header']; ?>topmenu_left.jpg" border="0" alt="" /></li>
<li name="navItem"><a href="<? print $site->url['about']; ?>">About Us</a></li>
<li name="navItem"><a onmouseover="setWindow('loginWindow');" href="<? print $site->url['billing']; ?>">Client Services</a></li>

Is the next jQuery code the best way to decrease an elements width?[code]I tried using the next code:[code]but that's not working, also not with '-20'.Maybe it's an idea to add this functionality? It's is already used in the .animate() function for changing the position of an element.
View 3 Replies View RelatedI need a code that when a button or image is clicked then a div's width and height are changed.
Ive managed to get a few codes that does this, but the real problem is that, the contents of the div is an embedded flash file and i thought that by setting the flash width and height to 100% then the flash would fit to the new size of the div, but it just didnt work.
I need a code that when a button is clicked then the div's and the flash's width and height are changed.
please have a look at the temp website latinunit net / temp / , you will understand where im coming from.
on the right hand side i have a flash chat in a div , div is controled by a script that allows it to follow the scrollers up and down.
My goal is to add a little button in the same div that says expand or maximise so when clicked the the div expands aswell as the flash file.

I want to set the width of a div to be the same width of the image inside the div.The following code works great. But...The images are different widths, so both wrappers are set to the width of the first image. Without having to add an ID to each wrapper or image, can the wrapper width be set to the image width using the name of the image as the unique identifier?
jQuery:
$(document).ready(function(){
var newWidth = $('div.wrapper img').attr('width');
$('div.wrapper').width(newWidth);
});
HTML:
<div class="wrapper">
<p><img src="image1.jpg" width="200" /><br />
Caption</p>
</div>

How can I use JavaScript to get the width of a div that isn't explicitly set in css?
View 9 Replies View RelatedI'm working with a web site that has frames defined as:
<frameset rows="60,*" frameborder="yes" border="0" framespacing="0" cols="*"

I need to get the width of "leftFrame" from a script running in one of the
other frames (usually "basefrm").
I tried parent.leftFrame.width, but it returns "undefined" (but
parent.leftFrame.name does return "leftFrame"). I suspect I need something
before ".leftFrame", since the framesets are nested. How would I refer to
leftFrame to get its width?
I have a text and I need to get its width in pixels. The font size is not fixed. I've been suggested to put the text inside of an invisible div and get the div's width. But I would need to force the div to shrink to fit
the text.
What are the variables I can use to find the width of a particular window? I have a moving ball thing on the page and want it to got the width of the current active window where the code is. I understand that there are different properties needed depending on the browser used.
View 3 Replies View RelatedI am trying to be able to manipulate the width and height of an <img> but do
not seem to be able.
"Yes", I know the JavaScript will "not" manip anything, which is ok. I
simply do not know how to capture the width or height. Once I can do that I
can manipulate them.
Here is the HTML for the <img>
<div class="ImgMnp" id="myImg" onmouseover="imgSize('myImg','fpImg)">
<img src="images/FirePlace.jpg" width="480" height="640" id="fpImg" />
</div>
Here is the JavaScript I tried to manipulate the <img>
function imgSize(myID,myImg)
{
var myDiv= document.getElementById(myID); //get correct <div>
var myImage=document.getElementById(myImg); //get correct <img>
var myWidth=myImage.style.width; //attempt to capture width of <img>
var myHeight=myHeight.style.height; //attempt to capture height of <img>
alert("myWidth+, +myHeight"); //show if I this function works
}
Will someone please tell me what I am doing wrong.
I'm using a third party libray and I can drag a diveand resize it. The
issue is, I have a textarea inside of it and I need to resize the width
of textarea and height of textarea along with it.
I know what the width and height of the div will be when it finishes
dragging (in "px"), so how do I convert the width and height in "px" to
the cols and rows of a textarea?
Is there a way to know the overall width of a piece of text? Not the width of, say, a single line P tag but any words it may contain.
I've been given a problem where text that is dynamically created is supposed to be neatly wrapped in a styled DIV.
Is it possible to get the width of a picture:
<img src="../graphics/press/bw21.jpg" width=400 height=555 alt="" border="0">
the make a box be exactly the width of the picture:
document.write('<div class="box" style="width:'+ w +'px">');
I am trying to create a very long dynamic document with fixed width
for the cells of my table iin HTML, I need to truncate some of the
information that I display to fit in the table.
As the document is very long I can not use the offsetwidth
functionality of the cell because then the user will see the
information being truncated, which is not desireable, I was wondering
if there is any way of calculating the width of the text displayed in
the "risky" rows on the fly before the whole document gets rendered.
I tried to display the information in the row and then try to truncate
it right away after using the offsetwidth to see the width of the text
in pixel, but this is not working as the offsetwidth needs the whole
document to be rendered before being able to calculate the exact
value.
I'm working on recreating a paper form as accurately as possible in XHTML. I can't keep my sanity with that man DIVs, so I'm using nested tables.
In most fields (TDs) I have a label and a text box, and I'd like to have the text box fit the width of the TD as accurately as possible, without going on to another line. As far as I've heard, the only way to do this is using JS to get the width of the TD and the label, and then adjust the width of the text box to fit.
I'm using FireFox 3.0.11 for development. For some reason, the width of the TDs is being reported incorrectly. I've tried .width, .style.width, .offsetWidth, .clientWidth and .scrollWidth. They all agree within a few pixels, but are horribly incorrect. My current screen resolution is 1400x1050, and I've taken a screenshot and measured that to confirm - the actual width of the TD is approx. 1130 pixels, but it's being reported by all of those JS functions as +/- 865 px.
None of the tables or TDs have widths defined, it's all just automatic sizing. The only width/size defined at all is an overall div with 2% margins on each side.
I have a bordered div with some text in it. Some of the text is one long string and thus runs outside of the div. The div stretches out to the width of the browser window so that long string of text runs all the way out past the edge of the scrollbar.
Is there a way I can use JavaScript to detect the width of the div from the edge of one border to the next and then convert that number into the number of characters that can fill that width?
I have the following code:
