How to show/hide a asp.net sub element with jquery

This method allows you to show/hide a form element without making another request against the server. It also works when the show/hide element is required by the asp.net code behind.

You can use any type of sub element under a dropdown with this script. You will need to use a CDN or download and host your own jquery-1.3.2.min.js file.

SCRIPT

<script type="text/javascript" src="/js/jquery-1.3.2.min.js"></script> <script type="text/javascript"> $(function() { $('#<%= Dropdown1.ClientID %>').change(function() { if (this.value=="My Value") { $('#<%= Element1.ClientID %> ').css({ visibility: 'visible' }); } else { $('#<%= Element1.ClientID %> ').css({ visibility: 'hidden' }); }}); }); </script>

 

HTML

<asp:DropDownList runat="server" ID="Dropdown1" class="required" >
<asp:ListItem Value=""> none</asp:ListItem>
<asp:ListItem Value="My Value">Some Text Here</asp:ListItem>
</asp:DropDownList>

<!-- place any element here with id="Element1" -->

text-shadow not working in chrome, css tricks

Here is the sample,

Text Shadow

And with no further adieu, here is the code:

for chrome:

  • text-shadow: -3px 3px 2px rgba(0,0,0,1);

For MS Browsers:

  • text-shadow: -3px 3px 2px 1px rgba(0,0,0,1)

For Both:

  • text-shadow: -3px 3px 2px rgba(0,0,0,1)
  • text-shadow: -3px 3px 2px 1px rgba(0,0,0,1)
Since CSS is read top down you can just place the version needed for crome above the general use/preferred method.

The volume (DRIVE:) was not optimized because an error was encountered: Neither Slab Consolidation nor Slab Analysis will run if slabs are less than 8 MB. (0x8900002D)

This error appears in the event viewer when the scheduled task "ScheduledDefrag" runs.

Cause: In most cases this is cause by the -k switch which tells the defrager to perform a slab consolidation on the selected volume. This will cause an error for slabs that are less than 8 MB, and will commonly toss an error on HyperV VM's.

Solution: remove the -k switch from the task.

  • Open scheduled tasks, Microsoft, windows, defrag: "ScheduledDefrag"
  • Now click properties, actions, edit [start a program]
  • under add arguments(optional): remove the -k and click "ok", "ok"

That's it, your done.

Change Style for Multiple Elements onClick: getElementById, getElementsByClassName, querySelectorAll oh my

With a bit of creative javascript and these Methods you can do some pretty neat stuff.

On this page I've create an example for multiple elements display block/none function based onclick function. You could also utilize checkbox.checked, onmouseover, or other such functions.

You can replace querySelectorAll with getElementsByClassName or getElementById for broader browser support or you can simply create a detector onload to look for an element on the page and hide it if the Method is supported with querySelector like this:

window.onload = function(){
 document.querySelector('#compat').style.display = 'none';
    }

The Code:

HTML

<div class="aa" style="display: block;">class: aa, no id</div>
<div class="aa" id="aa" style="display: block;">class: aa, id: aa</div>
<div class="bb" style="display: block;">class: bb, no id</div>
<div id="aa" style="display: block;">no class, id: aa</div>
<a onclick="showClass('.aa');" href="#">Looks for class: aa</a>
<a onclick="showClass('#aa, .bb');" href="#">Looks for class: bb, and id: aa</a>
<a onclick="showClass('.aa, .bb');" href="#">Looks for class: aa, bb</a>
<div id="compat" style="display:block;position:absolute;width:100%;height:100%;background-color:#fff;top:0;left:0;padding:50px; "><h1>Compatability Error!</h1>

<p>for suggestions, please go <a href="http://outdatedbrowser.com/en">here</a>.</p>
<a href="#" onClick="document.getElementById('compat').style.display = 'none';">Continue Anyways</a>

Javascript

function showClass(s){
 var e = [];
 var e = document.querySelectorAll(s);
 for (var i = 0; i < e.length; i++){
    if(!e[i])return true;

    if(e[i].style.display=="none"){
       e[i].style.display="block"
    } else {
       e[i].style.display="none"
    }
 }
 return true;
}

Use your imagination and see what you can do with it.

Here is a working example:

class: aa, no id
class: aa, id: aa
class: bb, no id
no class, id: aa
Looks for class: aa Looks for class: bb, and id: aa Looks for class: aa, bb

Compatability Error!

Government approved unlimited debt ceiling until February 7, in order to reopen the US government spending spree.

In a sad display of bi-partisanship our elected officials decided not only to increase the debt limit but to remove all spending limits until February 7th of 2014. With a record low approval rating the only thing that they have been able to agree on is that they want to spend more of your money. It may be time to clean house if we want to keep the US economy above water in the next few decades.

Do we really need 2.65 million federal employees?

Does the federal government really need 2.9+ Trillion of our money in 2013?

More spending means more taxes, in one form or another.
