Check Numbers Entered
Jul 23, 2005I am constructing an HTML questionnaire and one of the questions
requires people to rate some choices from 1 to 5, where 1 is their
favourite and 5 is their least favourite:
Car
Bus
Taxi cab
Train
Airplane
Each choice has an INPUT TYPE=TEXT tag to contain the response. I
also have a function that is called ONCHANGE in order to check that a
number is entered between 1 and 5:
function CheckNos(obj) {
if(obj.value.match(/[^d]/) || obj.value<1 || obj.value>5)
{alert("Please enter a number between 1 and 5");obj.value="";return
false}
}
This works fine, but ideally I would like a function that could check
ONCHANGE that someone has not filled in the same number twice, for
example answered "1" for all of them. They are only allowed to use
each rating number once, so rating their choice 1 to 5.
Can anyone suggest a short function that could accomplish this easily?
Could I use some kind of array with 5 elements and allocate a flag
value once that number had been chosen, then check that the value had
been set?
Plausability Check For Numbers

smaller than 100000 and there should no , or . be inside the value. otherwise
they should see an alert message. Code:

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?

Check If Textfield Has Numbers Then Submit Form?
Jun 1, 2011I have a form with a text box where users can enter a 10 digit code. The 10 digit code can be just numbers/letters (eg. 0123456789 or abcdefghij) or it can be a mixture (eg. 0a1b2c3d4e).

Jul 23, 2005if (123 > 33) will return true
and
if ("123" > 33) will return true
So my question is, if the above behaviors are the same?? If string is
a number, and compare with another number, it will be the same behavior as compare 2 numbers?
In this case, it is comparing 2 strings that are numbers, so they are
string comparisons here. correct?
if ("123" > "33") will return true
In this case, "33a" is not a number, that's why when it compare with
another number, it always return false. correct?
if ("33a" > 33) will return false...

Check If String Has A Certain Email Format?
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...
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
