Is there anyway to set my code in javascript to ignore errors
I have an error that comes up on ie but everything workes fine and i can't find the source of the error -- can i tell the browser to ignore it?
The page im loading with $.get has a syntax error that is killing my entire script. Is there anyway to test if it contains a syntax error
and/or just ignore it?
$.get('http://www.example.com/',function(response){
var someText = $(response).find('#myDiv').text();
// Script doesnt run after this because response contains a syntax

I am a novice, almost to an intermediate-level JavaScript guy, so much of this is new to me. I appreciate your patience reading this.
I have a routine that creates some HTML on the fly (updateFilters() function) and after the HTML is created, I attempt to access some fields (elements) on the form itself.
I works fine if I place an alert() statement after the HTML is created, but when I remove, the code errors out.
I have tried the setTimeout() statement, but I cannot grab the element --- undefined or null is returned. It seems that the form is the only element I can get a handle on --- everything else is undefined or null...
Here is the code:
function editQuery() {
var f;
var x;
var myForm = document.forms[0];
// Get the row filters that were used in the last query..
for (f = 1; f < 16; f++) {
var filter = eval("myForm.FilterList_" + f);
if (filter.selectedIndex > 0) {
var methodElement = element("FilterMethod_" + f);
var methodIndex = methodElement.selectedIndex;
var savedFilterMethodValue = methodElement.options[methodIndex].text;
var choicesElement = element("FilterChoices_" + f);
var choicesIndex = choicesElement.selectedIndex;
if (isNaN(choicesIndex)) {
var savedFitlerValues = choicesElement.value;
}
else {
var savedFitlerValues = choicesElement.options[choicesIndex].text;
}
updateFilters(filter); // update the filters
// take the saved methods and values and then update the selections
// Alert here makes the code work..
// alert("Try this");
// Wait for HTML..
setTimeout("completeEdit()", 1000);
function completeEdit() {
// Since the object was updated, get the object again..
var methodElement = element("FilterMethod_" + f);
for (x = 0; x < methodElement.options.length; x++) {
if (methodElement.options[x].text == savedFilterMethodValue) {
methodElement.options[x].selected = true;
break;
}
else {
methodElement.options[x].selected = false;
}
}
// Since the object was updated, get the object again..
var choicesElement = element("FilterChoices_" + f);
for (x = 0; x < choicesElement.options.length; x++) {
if (choicesElement.options[x].text == savedFitlerValues) {
choicesElement.options[x].selected = true;
break;
}
else {
choicesElement.options[x].selected = false;
}
}
// Only display next row if f = 2..
// If only one row was used, no reason display the next row..
if (f == 2) {
displayNextFilter(f - 1); // display it
}
}
clearTimeout(timeOut);
}
}
}
Do I have to pass the object (the form, the elements) to the completeEdit() function in the setTimeout() statement?
I have the following function:
function show('id') {
document.all['id'].style.visibilty = 'visible'
}
and I'm using the following code to call the function:
show('contacts');
however I am getting an "Object Expected" error. I know the JavaScript itself works, because I've tested it using a direct call using the code itself, rather than the function, if you get what I mean.
Can anyone tell me where I've gone wrong?
I am trying to use the following code to trap JavaScript errors. It seems to work well in IE and FF but not in Opera. I expect I must have turned it off somewhere in the "preferences" but I can't find where. I'm using Opera 10.10.

I am using jquery to getjson from my service. The service works perfectly if you use fiddler and through the mvc code behind. You can also call the URL directly in the browser and it sends back the correct data.
But when I execute the below code it calls the service but nothing comes back or there are errors I cannot figure out what they might be. It seems like a very simple test of the getjson function.

How can we identify logical errors from other types of errors?

is there any smart way to do split, and ignore certain delimiters, like:
var s = "don't use ',' as part of data, some other text";
arr = s.split(",");
// obviously don't want s to be splitted at ','
I am in the process of editing the below code I found online, I have a

I'm trying to use .load to get a simple web page. In the documentation for the .load function, I see that I can just return parts of page. I pass through the <body> element in order to just get the body, and not the headers of the html document, however in FireFox, it seems to still be returning all the headers. How can I use .load to ignore the headers.

It should work with IE, FF, Sarari and Chrome browser.Problem:I am able to capture and cancel it and it perfectly works with FF and Chrome, however it seems like IE and safari always process menubar shortcuts, even if you have cancelled the bubbling and returned false.I am just wondering if anyone ever be able to cancel the menubar shortcuts under IE and Safari?
View 7 Replies View RelatedI want the page to completely ignore all mouse clicks. I can create
the onmouseclick event and return false, but that only disables
certain types of things. I can still, for example, click in a text box
and then type something or change the selection in a dropdown list. I
tried returning false in the onmousedown event, but that didn't do the
trick. I'd rather not have to disabled all the controls on the page.
Any ideas?
I have some date calculations that add a time span to a date. The problem is, when I add a time span that is a whole number of days to a date, the result can be +/- 1 hour due to daylight savings. Is there anyway to disable this?
View 2 Replies View RelatedI'd like to use the jQuery validation plugin as seen on the following example: [URL]
But it doesn't work properly if I use inline/in-filed labels.

My question is, how would I change all text within class one to say red (including sub-divs/spans etc), whilst completely ignoring the text with the ignore class(es)?
How can ignore queuing in mouseover/mouseout in such codes like this:

We have been using the following js/regex to find and replace all non-alphanumeric characters apart from - and + outputString = outputString.replace(/[^w|^+|^-]*/g, "");
However it doesn't work entirely - it doesn't replace the ^ and | characters. I can't help but wonder if this is something to do with the ^ and | being used as meta-characters in the regex itself.
I've tried switching to use [W|^+|^-], but that replaces the - and +. I thought that possibly a lookahead assertion may be the answer, but I'm not very sure how to implement them.
Trying to use the [URL] I would like to beable to ignore default values, but am sort of stuck. I already looked through all 42 results after searching for how to validate while ignoring default value. I have tried:

I'm trying to write/find a regular expression for finding ampersands but not HTML entites.I have this which finds entities but can't figure out how to ignore entities and return unmatched "&"

I'm using HAML to make html templates but am having a problem in writing attributes which will be replaced with JavaScript string templating.
The line in question looks like this:
%div{:class => "<%= from_class %>"}

I don't want that to happen in this case... Anyone know how to do this?
Go these two image buttons:
<input type="image" src="images/Update.png" name="btnSubmit" value="Update"/>
<input type="image" src="images/Cancel.png" value="Cancel" name="btnCancel" class="cancel" onclick="hide_edit_div()" />
Now, even clicking on the Cancel button runs the submithandler. How do I modify it to ignore it?

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?
