How To Suppress Function Key

Oct 14, 2006

I need to suppress the function keys (F1, F2, F3 ecc.) to use these keys to do other operations within the web pages of my application.

I wrote this code:

document.onkeydown=function(evt) {

if (evt==undefined) evt="";

var keycode = (window.event)?window.event.keyCode:evt.keyCode;

alert("onkeydown: "+keycode);
return false;
};

It works fine with Firefox but IE seems to ignore the "return false" and I'm not able to byepass this problem. How can I do?

Suppress F5 Key

Jul 23, 2005

I'm working on an app where the refreshing of the window by pressing the
F5 key needs to be suppressed. I thought it would be straightforward but
I can't get it to work. This is the code I'm currently trying:

okdh = function(e) {
if (e.which == 116) e.preventDefault();
}
document.addEventListener("keydown", okdh, false);


e.which returns a number
e.which returns 116 when the F5 key is pressed
e.cancelable is true when the F5 key is pressed

Is the default action of the F5 key something that can be suppressed?

Disable/Suppress Alerts?

Jul 19, 2006

Is it possible to disable/suppress alert popups in javascript? I need
to write a function that will loop through a form's inputs and
"manually" fire their onchange events (if found). Some of those
functions could popup alert boxes which I'd like to be able to
temporarily suppress.

Geocities - How Can I Suppress The Banner?

Jul 20, 2005

How can I identify the Table that the Geocities banner is in?
I tried

document.all.tags("table")[0].style.display = 'none'

no matter what number I used nothing worked.

Using CSS script

TABLE {display:none}

This works, but then I have to go to each table seperately and set the
display to block.

I would like to be able to directly identify the table the banner is
in, so I can disable only the 1 table.

Suppress OnBlur Validation Alert On Window Close

Dec 10, 2009

Using Javascript, ASP.net with C# code behind. I am validating a textbox using the onblur event. It is being validated in that it must have an alphanumeric entry before the user tabs off of it to the next box. The validation part works, the part that doesn't work is that I get the validation alert textbox if I close the window. I have a workaround in that I am assigning that textbox a character using windo.onberforeunload but I know that isn't right.

Here is what I have so far...
Code behind on Page_Load...
txtCLBRTNWC.Attributes.Add("onblur", "return reqVLD(this)");

Here is my textbox field...
<asp:TextBox ID="txtCLBRTNWC" runat="server" Width="75" MaxLength="4"
ontextchanged="txtCLBRTNWC_TextChanged" TabIndex="1"
onkeyup="clbwclngCHK(this);" ></asp:TextBox>

And here are the 2 functions being used...
function reqVLD(alphanumericChar){
var chk = /^[a-zA-Z0-9]+$/;
// var boxid = document.getElementById("<%=txtCLBRTNWC.ClientID%>").value;
// var matchArray = boxid.match(chk);
if(document.getElementById("<%=txtCLBRTNWC.ClientID%>").value.match(chk)){
return true;
} else {
document.getElementById("<%=txtCLBRTNWC.ClientID%>").focus();
document.getElementById("<%=txtCLBRTNWC.ClientID%>").value = "";
alert("Please enter a Work Center.");
return false;
}}
function clbwclngCHK(obj_in)//When txtCLBRTNWC entry hits the max of 4 auto focuses to next box. {
if (obj_in.value.length == 4) document.getElementById("<%=txtSTRTDT.ClientID%>").focus();
}

Here is my work around...
window.onbeforeunload = function (){
document.getElementById("<%=txtCLBRTNWC.ClientID%>").value = "1";
}

User has to enter something in box before they can move on. This is checked and validating using an onblur event. Problem is, the onblur event fires if closingexiting the window.

JQuery :: Google.load Function Doesn't Work If Called From Ready Function?

Jul 1, 2010

I'm using the Google AJAX APIs, but some reason google.load works when run through normal javascript, but if I call the method from my jquery ready function it doesn't work. Code and output is below

page.html
<script type="text/javascript">
loadGoogleStuff();
function loaded() {
console.debug("in loaded function");
}
[Code]...

window.loadFirebugConsole is not a function If I comment out line 3 in code.js, the console debug runs okay, so the ready function is running okay. Even though there's a reference to Firebug, the same error occurs in Safari too. Nothing on the page loads.

JQuery :: Timing Not Quite Right - Hide() Function Calls Immediately Without Waiting For The Animate() Function To Run

Apr 1, 2010

I'm using jQuery 1.4 to hide a div (#cartPop) when the "close" link inside of it (#cartPop a) is clicked. Since I'm using animate() to fade the div out (opacity), I also have to use hide() to get rid of the div once it has faded out (otherwise the invisible div, which is on a higher z-index, blocks the elements on a lower z-index).

Code:

The problem is that the hide() function calls immediately without waiting for the animate() function to run. Even if I append a delay() function before hide() like so:

Code:

...it still doesn't wait.

JQuery :: Pass ID # To Function In Order To Use One Function Instead Of Separate Ones?

Oct 1, 2010

I am trying to minimize the amount of script that I use on my website. I have sections of each page; each section has the same basic layout. The divs and images that I want to make appear and disappear all have nearly identical ids, the only difference is the number at the end of the id.Is there a way to get one script to automatically detect which id number has been clicked and then show all elements with the same number at the end of the id? I would also like it to hide the elements in the hide function below (basically they are the elements that do not share the same id number).I currently have everything working the way I want it to using multiple functions like the one below but I woul

$("#2thumbNail2 , #ledBar").click(function () {
$("#type201 , #type203 , #type204").hide();
$("#image201 , #image203 , #image204").fadeOut("slow");

JQuery :: Calling A Function Within The Ready Function From Another File?

Jun 18, 2010

I have 2 javascript files: 1 containing generic functions for my site used sitewide and another for a particular web page containing just the javascript for that page. The page is also calling the jQuery javascript file.

What I want to do is have a javascript function in my main javascript file which uses features of jQuery such as show, hide etc. and then I want to call this javascript function from the other page specific javascript file.

[Code]...

This does not work and so was wondering if anyone can point me in the right direction as to how to achieve this or something similar.

JQuery :: Function Returns The Code Inside The Function?

I am having a strange problem with a javascript function that does not return the value but returns the code inside the function. My best guess is that I am incorrectly calling the function hasLandedOn()and jquery is interpeting it. Why is this happening? I highlighted the parts in red.-Tom ReeseThe following is returned NOT the variable imageName.

function hasLandedOn(){
var selectorLoc = $("#selector").offset();

JQuery :: Passing The Success Function Name Into A Generic Function?

Jan 6, 2012

I have a lot of similar instances of the following code on my page:

$('#btnEditParty').click(function () {
$.ajax({
type: "POST",
url: "WardAdmin.aspx/GetParty",

[Code]....

I'd like to create a generic function to save repeating a lot of code and then just pass in the relevant values.

I'm fine with that, the only thing I'm not sure about is if/how I can pass in a function name to be called on success/fail.

This post is where I was doing something similar to save repeated code: [URL]

In a similar way is there a way of passing in a function name to be called on success?

SetInterval Of Function - Called From Function - Display And Update

If I use kiTime() under the text field I will get the current time (or at least the time the app was opened), however if I call updateClock() it's blank.
