Suppress Script Errors

will catch the error only when the script is within the same source
file.

How can we identify logical errors from other types of errors?
View 4 Replies View RelatedI'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?
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?
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.
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.
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.
is there anything wrong with this script as i keep gettin an error message in IE with menu item 1:
//menu methods
function ehandler(event,theobj){
for (var i=1; i<= theobj.numberofmenuitems; i++){
var shutdiv =eval( "menuitem"+i+".thediv");
shutdiv.style.visibility="hidden";
}
theobj.thediv.style.visibility="visible";
this menu is related to a drop down feature later on!
How do I get to see the details of JS errors in IE? I have some problem in IE that isn't showing up in FF or Opera. Is there an error window in IE that I can open up and look at warnings and errors?
View 4 Replies View RelatedI am in a little over my head here trying to make a template for this PHP script. I am trying to work out all javascript errors.
So far I only have one error on the index page and no other pages. In IE8 at the bottom it shows me the little error icon and when I click it, it shows me:
Line: 2
Char: 18579
Error: Object doesn't support this property or method
Code: 0
URL: http://www.mysocialengine.com/demo/woolton/index.php
I am trying to locate this error in the source code, but cannot figure it out. Can someone maybe take a look at the source and point me in the direction to what IE8 is finding as an error? It's weird that there are javascript errors only on the home page when I use the same header and footer file for the entire web site.
Take a look at my code then I'll tell you what error I get...
The element with that id has been created and I still get this error when I try to style it...
My browser is Google Chrome.
I'm using javascript for my client validation and I would like this to work the way I wanted to. I have three textboxes for last name, middle name and firstname. All the fields are mandatory and if the form is submitted there would be an error to display below the textbox. The problem now is I couldn't show three errors at once. I could only show one error at a time. The error msgs are specific that is "Last name required", "First name requiredHere's my JS structure
function validate()
{
if (textbox1 == empty)

When i visit a majority of the pages on Dic i receive the following javascript error:
Webpage error details:
Message:
I am using IE 8 with nothing disabled. The browser also goes into compatabilty mode every time this error happens. The screen will go competely white and i will have to do a refresh to get anything to show up.
I am getting the message in the bottom status bar on my site www.pashmina-shawls.com Done but with errors on page? It doesnt happen on the index page, only on all the other pages, the reason for this is i use a template for all pages except the index page, and all pages using template show this error message, please help and will this effect the functioning of the site?
View 3 Replies View RelatedJust ran across something interesting in Mozilla and Firefox. I don't think it qualifies as a bug because it's probably something I should not do - even tho it validates.
Having the following line (in the head)...
<script type='text/javascript' src=''></script>
...causes this:
Error: syntax error
Source File: http://cross-browser.loc/toys/toolbars.html
Line: 1
Source Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
And having the follow line...
<link rel='stylesheet' type='text/css' href=''>
...causes this:
Error: The stylesheet http://cross-browser.loc/toys/toolbars.html was not loaded because its MIME type, "text/html", is not "text/css".
The empty src or href attribute seems to cause it to load itself (the html file) as a script or as css.
I'v just finished the first web site i wrote which encorporates some javascript. It worked fine on my test server, but as soon as i moved it to the production box, I now get all sorts of errors like :Unterminated string constant when i open the first page, and Object expected when i try to call a javascript function by clicking on a menu item. Is there some sort of configuration that must happen on my production box? The same coding works fine on the one server but not on the other.
