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?
Is there a way to calculate the .offsetLeft or .left of a character in a string relative the element that contains the string? I'm just trying to wrap each character in an element and position the characters independently, so I have to set the .position to absolute, and set the .left and .top on each element as I create it so I can move the elements later on.

Is there a way in a regexp to *not* match a fixed string value?
Using [^blah] gives matches to anything not containing *any* of letters b,l,a and h. Whereas I want to match anything that does not containing the exact string 'blah', i.e. *all* the letters.

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.
I am trying to do a pattern match and check something in a condition but cant get it to work. The first value changes and I need to check and do something if I get a hit on it.
Code: var mydata = "?first=one&second=two&third=three"; if (mydata.indexOf("first") == "something") { alert("No Hit"); } else { alert("Hit"); }
Basically I am trying to find out if first is equal to one in the mydata string. My above attempt is not working.

Also, How do I format with indentations and as non wraping text the messages I send to this forum?
I want to check if the user enters alphabet or numbers only in the text box. If the user enters non-alphabet or non-numbers, I should pop up a message and doesn't allow the user to do that. I am using regular expression to do the checking. But it seems it always return false...
