I have been working on a project that requires me to create a vertical auto-hide toolbar that appears on the right side of the webpage. I am not even sure if that is possible using javascript as I am quite new to javascript.
|
|
|
|
|
If you question is if it is possible in Javascript?
My Answer is yes quite possible. As a matter of fact you just gave me the idea. I will implement this for my in house application today.
For your help:

1. CSS visibility
2. OnMouseOver action
3. OnMouseOut action
I wish I could believe there is an after life.

I thinking about posting some code to help out, but every circumstance if different. It's actually a combo of jquery and javascript, and i'm afraid you won't understand it.
It takes a panel you create in asp.net at left -360px with the id of "_ib_ProductEditor_Toolbox_Next", create a event bind in the dom for click, loads up dynamic html for a progress wheel, and then loads data, parts list, and fly's out to the right using animation. Requires Jquery 1.6 something. it makes a close link in the upper right, and create another bind, to animate the close back to -360px.
It should give you and idea of how to start yours at least.
$(document).ready(function () {
$('[id*="_ib_ProductEditor_Toolbox_Next"]').click(function () {
toolbox_ProductItem_Next_MouseOver();
return false;
});
});
function toolbox_ProductItem_Next_MouseOver() {

Oh men! Why your simple auto-hide panel is so complicated? 2 css classes and maybe one ajax for dynamic loading of content should be enough!

It auto loads a product database based on filters, so you don't have to leave the page to edit a product SKU with over 100 fields.
It's what evolved after hundreds of complaints from the initial simple ones we made in the beginning.

Ok. I understand that but why not replace those hardcoded styles with css classes and jQuery().addClass("xxx")?
Why you using selector: panel_ProductEditor_ToolBox_Next? Its obviously part of asp.net generated id. Why not set CssClass property just for selecting?
Than you have clear selector that will not change when you edit parent container(s)?
Why you setting both innerText and innerHtml? For simple string like "Close Panel" one from them is enough and they mean the same?
For simple case like in question this is achievable with single css rule:
.parent-container:hover .autohider{
display:block;
}
.parent-container .autohider{
display:none;
}
and html
<div class="parent-container">
<div class="autohider">
some hider content
</div>
</div>
I don't say that it's wrong. Just overcomplicated.

It's part of a back end application, that controls the front end of the website.
Customers were changing the css and messing it up, so we just hard coded the fonts. Got tired of having to fix it all on every installation.
We just use css names now for jquery on certain modules, so we can do a mass edit using each on css types. It appeared to be more effective and faster in speed.
on the innertext versus innerhtml, that's something I'm still messing with. It dates back to earlier in the year with compatibility issues between IE, Firefox, it use to be 2 different scripts, but I tried to combine them into one. Still working on that, and help was hard to find.
That script is still experimental, and is the 5th revision of it. At least the complaints went away on it, and it renders correctly every time, on both browsers and versions. It can use more optimization, but the speed and performance of the fly out tab is quite impressive and very reliable.
Feel free to suggest some optimizations, and I'll rewrite that module in October using your feedback.

So it's customer doings... I should suspect that.
In that case. Maybe you should consider using css from webresource.axd as part of some assembly. Just like DevExpress. But it is harder to maintain and deploy than just simple css file.
But maybe it can suit your situation.
I was also experimenting in doing something like this purely in css. It's posible, but seems to work for now nice only in FF. It's works like flag on/off in IE, Opera. In Chrome looks like crap.
But maybe you can do something with that:
http://jsfiddle.net/LnbuM/[^]
Another idea: http://jqueryui.com/demos/hide/[^]
But since this framework uses css as well and your customer is breaking that...
But this not change fact that you hardcoded part of asp.net id into js. I stumble on bugs coming from that few times. In current project I created in aspx file js object containing aspx controls ids for selecting them from jQuery. I benefit from compilation of pages:
<script>
var selector = '<%=control.ClientId%>'
</script>
but it's have to be separated from main js script in .js file.
So next time i will use some css class to avoid this separation.
But mainly i would cut if parts with "-360px" and use some predefined even only for this (without css rules). jQuery().hasClass(), addClass, toggleClass, removeClass functions are specifically for something like this. Since you have in auto hider only 2 states (visible/not visible) you can toggle this in single event:
$('.autohider').toggleClass('visible');
As for innerText/Html. What differences between browsers you have found? I am not specification expert. But it's pretty basic. Text sets text, and html set html. If it's not in all browsers, use
$().text and $().html functions.
Creating elements? I would rather use
$('.container').append('<td style="someStyle">someText</td>'). It's hardcoded to but for me easier for eyes and cause of that for maintain.
Maybe I sound like jQuery fan boy, but why you should reinvent the wheel since jQuery folks done that before and it's works? I think they wheel is more... round then yours or main.

I found that IE has a different way or syntax for creating html in the dom. Firefox, Safari was pretty straight forward, but IE used table.insertRow(-1), and InnerText instead of InnerHTML. So I spent a week looking at the difference between the two, and found that you can set stuff, but it won't work or produce an error unless it's way off base. So IE just ignores InnerHTML, but picks up InnerText. Go Figure?. I didn't want to mess with more asp.net elements, so I just made them in Javascript. The main point was that if it's even used, then it's created on the fly by the client, if not, there's no extra asp.net code needed.
Drove me nuts!
So the big picture here, is that it's a very small piece of code in a large Server DLL Control (6 megs). The script is embedded, and everything is code behind.
The hard coded id is on the asp.net side, the jquery uses a wildcard for the id, in which the prefix can be anything, as long as the suffix matches. So masterpages are not a problem.
I didn't think of using CSS at the time, just wrote it all in mostly javascript. I suppose there are a dozen ways to do it.
I use to type out the HTML like your example and append it, just thought I would try something different this time. The createElement seems a little faster than just appending text.
I'm amazed at really fast it runs, so I'm going to stick with it for now.

Just out of curiosity how did you tested it?

Visual test, plus count 1 one thousand, 2 one thousand,
It was quite obvious compared to the previous version, may be it was better tsql, no wrote that last.

Hi, I recently mentioned this site on a Lounge post, but I feel it's so relevant to the area of "responsive design," using the web-centric tools, JavaScript + jQuery, HTML 5, CSS 3, etc., that it really deserves mention, again, here.
Brad Frost's site, "This is Responsive:" [^]: this is perhaps the best site in this area I've come across.
Check out his UI demonstrations, as well as his source-code, and fluently expressed comments and explanations.
best, Bill

Hey guys, I'm new to Jquery and I'm trying to use
jCapSlide in a datalist,
<asp:DataList ID="DataListList" runat="server" DataSourceID="ObjectDataSourceList"
RepeatColumns="5" CellPadding="5" CellSpacing="5"
OnItemDataBound="DataListList_ItemDataBound">
<ItemTemplate>
<div id="capslide_img_cont" class="ic_container">
<asp:Image ImageUrl='<%#Eval("Images.Image.Virtual_FileName") %>' ID="MainImage"
CssClass="NewsImage1" runat="server" />
<div class="overlay" style="display: none;">
</div>
<div class="ic_caption">
<p class="ic_category">
'<%# Eval("Category.cName")%>'</p>
<h3>
'<%# Eval("pTitle") %>'</h3>
<p class="ic_text">
'<%# Eval("pTitle") %>'
</p>
</div>
</div>
</ItemTemplate>
</asp:DataList>
with this Function
<script type="text/javascript">
$(function () {
$("#capslide_img_cont").capslide({
caption_color: 'white',
caption_bgcolor: 'black',
overlay_bgcolor: 'black',
border: '',
showcaption: false
});
});
</script>
There are 3 records, this applies on the first one but not the other two,
I think the problem is repeated
id="capslide_img_cont" but can't seem to fix it.
can you help me out ?
It's deeply appreciated
|
|
|
|
|
try
$('[id*="capslide_img_cont"]')
it's a wildcard that accepts any prefix, and the suffix you enter. asp.net will inject a prefix like $content100 in front of your id name. so it becomes something like $content100_capside_img_cont
As far as the 2nd and 3rd record goes, I'm not sure yet, not enough info
|
|
|
|
|
$("#capslide_img_cont") will get the first element.if you use 'Id' attribute,there will be not only one div with 'id' attribute.it's not good.so I suggest using 'name' attribute ,and then $("div[name='capslide_img_cont']").capslide.or using 'class' attribute if no one use 'ic_container' except this div.zhe code below:
<script type="text/javascript">
$(function () {
$(".capslide_img_cont").capslide({
caption_color: 'white',
caption_bgcolor: 'black',
overlay_bgcolor: 'black',
border: '',
showcaption: false
});
});
</script>

I want to calculate the difference between two dates and the result should get in Year,Month and Date format. While calculating the difference it should take the end date also.
eg: 01/09/2012 - 30/09/2012 = 1 Month
01/02/2012 - 29/02/2012 = 1 Month
01/08/2012 - 10/08/2012 = 1 Month and 10 Days
01/01/2012 - 31/12/2012 = 1 Year
01/01/2012 - 10/01/2013 = 1 Year and 10 days

I am trying to select all the elements in a Listbox/SelectBox.
At the moment I am using the following function *which is working*, the only thing is it takes around 10 seconds to select all elements(of which there are 652).
I'm a beginner at javascript so I was wondering whether anyone knew of a faster way to select all elements.
<script>
function selectAll(selectBox, selectAll, ensureOneSelected) {
var selectBoxElement = null;
var selectBoxOption = null;
var boolSelect = selectAll;
if (typeof selectBox == "string") {
selectBoxElement = document.getElementById(selectBox);
selectBoxOption = selectBoxElement.options;
}
if (selectBoxElement.type == "select-multiple") {
var max = (selectBoxOption.length);
var modMaxUnrollFactor = (max % 4);
max -= modMaxUnrollFactor ;
for(var i = 0; i < max; i+=4){
selectBoxOption[i].selected = boolSelect;
selectBoxOption[i + 1].selected = boolSelect;
selectBoxOption[i + 2].selected = boolSelect;
selectBoxOption[i + 3].selected = boolSelect;
}
for (var i = max; i < selectBoxOption.length; i++) {
selectBoxOption[i].selected = boolSelect;
}
if (typeof ensureOneSelected == "boolean") {
if(selectBoxOption[0].selected == false)
{
selectBoxOption[0].selected = ensureOneSelected;
}
}
}
}
</script>
thanks in advance

What is with the unroll factor and two loops? That is pointless ... running a for loop 600 times isn't what's slow.
Manipulating the DOM can be slow. You might do better to get .innerHTML, do a regex replace for '<option( selected)?' with either '<option' or '<option selected', and then reassign .innerHTML.
