If Statement To Check Whether String Is A String Is Returning False
Jan 25, 2011I 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?

May 30, 2011I 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.
Check Last 15 Characters Of A String For A Space/tag?
Jun 27, 2011So 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...

Check The Content Of A String Against Set Criteria
Aug 31, 2005I 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?

Aug 28, 2010i am trying to pass text from one select box to another select box. The logic is if 10 are added, no more passing must happen. Also if an item is already added, it mustn't be added again.I am using the for loop to check the existence of an item but it is not working: what am i doing wrong?
Code:
function PassSelectValues(){

why isn't counter incrementing at all? The alert message box does appear saying item exists but the item gets added anyway.
Recursive Function With For Loop, For Loop Is Breaking When Calling Itself
Jan 22, 2011I have been looking at this code for two evenings now, and rewrote it 4 times already. It started out as jQuery code and now it's just concatenating strings together.
What I'm trying to do: Build a menu/outline using unordered lists from a multidimensional array.
What is happening: Inside the buildMenuHTML function, if I call buildMenuHTML, the for loop only happens once (i.e. only for 'i' having a value of '0'.) If I comment out the call to itself, it goes through the for loop all 3 times, but obviously the submenus are not created.
Here is the test object:
test = [
{
"name" : "Menu 1",
"url" : "menu1.html",
"submenu" : [
[Code].....
'Menu 2' and 'Menu 3' don't show up! I'm sure it's something small that I'm overlooking.
Send A Loop Variable (i) To A Function Inside The Loop
Aug 4, 2011I'm looking to send a loop variable (i) to a function inside the loop, but I can't seem to get it to use the value I want, it keeps making it a reference of i and therefore the function is always called using the last value of i rather than the one it was set with.
So if i have 5 Tabs then Tab 1, when clicked, should call DefaultTabClick(0) and so on rather than always using 4 for any of the tabs.

Oct 4, 2011Here is the HTML: [URL] I'm trying to uncheck the selected radio button, then set the value to 1 (Yes), basically overwriting theinitialvalue to 1. I've looked at prop(), val(), and attr(), and just don't know where to start. Should I select $('#set_q157 input') or$('#set_q157 input:radio'), or each individual radio?
Do I need to each them, and check if its checked, then change its value, or is there a way to select all three inputs as just one radial button? It would also need to work if the input has not yet been checked.
