I have a simple example below showing how when I pass in the value of the value attribute of option node, and then use if operator to check whether parameter is a string or not, even though it's a string, it converts it to false boolean and triggers the else statement rather than calling a function.callback should be a string so why is it saying otherwise?

How to check if some char in textbox contains one of the ones in string "allowedChars"
I am running the scripts below which should return a string containing a URL.So far, it cannot find the form contents in Firefox, but displays the non-dynamic data such as ?Location=. It won't work at all in IE.

I have a very simple PHP script that returns JSON like this:
{"question":"What day is it?"}
And I'm trying to call it from another page using Ajax. My code looks like this:
var url = "/test.php";
$.get(url,
function(data){
$.each(data, function(i, value) {
alert(value);
}, "json"
);
});
When I run it I get each character printed out one at a time in a separate alert. And then when I used this line of code:
alert(typeof data);
It tells me that 'data' is a string. Shouldn't it be a JSON object?

I am working on a script that seems impossible to work. I want to click on a link, and if the .text() is the same as a classname of a div, I want to do stuff with the div. The problem is that I can't imagine how to set up the if-state. Right now the script is like this:
$(document).ready(function(){
var filterTrig = $('#sortPort a').html();
$('#sortPort a').click(function() {
$('.listItem').each(function(){
if (!filterTrig == $(this).hasClass(filterTrig).html()){
$('listItem').addClass('test'); //later on, animations
}} return false; }); });
The script runs here: [URL]. I have turned off all other javascript to work only with this, if the site seems broken. The filterbox to the left will filter the div items listed to the right. All "boxes" in the list is a div with classname listItem + classes equal to the a.text() in the filters (leftbox). It is thoose divs I´m trying to animte with clicks.
i need a check that can go through a string to see if it contains any numbers.

Using jQuery v1.4.2, Firefox 3.6.6, Chrome 4.1, IE 6,7,8.
I'm using jQuery .css() function to get the value of the css attribute "background". The attribute has not previously been assigned a value (either in script or style sheet).
e.g. alert($(this).css("background"));
In Firefox and Chrome, the return value is an empty string (""). However in IE 6,7,8, the return value is "undefined".
It also makes the following statement impossible:
alert($(this).css("background").indexOf("somepic.gif"));
Because css() in IE doesn't return a blank string, doing indexOf() raises an error.
cross-browser scripting compatibility, for jQuery to return a blank string *for all browsers* if the css attribute isn't set. Otherwise we have to check for both "" or "undefined" which is the sort of pain jQuery users are trying to avoid.
I have thought about using the standard email checker pattern but we have had problems in the past so looking to check if the string follows these simple rules.
has no spaces, has a character/s at the start followed by an @ then has a character/s followed by a (dot) then another character/s
i.e
a@a.a
aa@aa.aa
aaa@aaaaaaaaa.aaa
i am not sure how the standard pattern works but feel that it may be to complex which causes some email address to fail.
So I want to be able to check the last 15 characters of a string for either <br /> or a space. I know how to do this with PHP but I have no clue how to do this with Javascript and Google is failing me. Could someone point me in the right direction?
Example string: var string = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat."
I'm assuming this will be done with lastIndexOf but I do not know how to do it. So to reiterate, I want to check to see if either a space exists, or <br />, delete everything after that, and return the string. So the output of the example string would be...
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo

I was just wondering how to go about checking the content of a string to see if it matches a set criteria?
For example, if I want to make sure somebody enters a date as mm/yyyy, how do I check to ensure there are:
2 numbers between 1 and 12 before the /.4 numbers between 2005 and 2020 after the /.And that the / appears between the two. I know in PHP you would use a regular expression, but how do you do it in Javascript?
I am trying to check for Arabic characters in a string using Regular expressions. This should return true, as the string in the str variable is indeed Arabic character. But it returns false.

Ive just started to learn JavaScript, and I have trouble to write JavaScript code which checks a string to contain at minimum one uppercase letter, one lowercase letter one number and one special character with no white space allowed.
View 4 Replies View RelatedSo for whatever reason the convertToArray function in the following code returns false if the argument is more than 1 character long. If it's 1 character long it just returns the character as an array with only one value.What I'm trying to do is take a string of numbers, plus signs, and minus signs and convert it to an array.
