i am trying to validate if a certain company was already picked for an application. the companyList format is:
60,261,420 ( a list of companyID)
I used
cID = $('#coName').val().split('::')[1];
to get the id only.
I am calling this function by passing say 60:
findCompany = function(value) {
var v = /^.+60,261,420$/.test(value);
alert(v);
}
when I pass the exact same string, i get false. any help?
Well if your company list is a list of numeric IDs like that, you need to make the resulting regular expression actually be the correct expression — if that's even the way you want to do it.
Another option is to just make an array, and then test for the value being in the array.
As a regex, though, what you could do is this:
var companyList = [<cfoutput> whatever </cfoutput>]; // get company ID list as an array of numbers
var companyRegex = new RegExp("^(?:" + companyList.join('|') + ")$");
Then you can say:
function findCompany(id) {
if (companyRegex.test(id)) alert(id + " is already in the list!");
}
Why not split the string into an array, like you did for your testing, iterate over the list and check if it's in?
A regexp just for that is balls, overhead and slower. A lot.
Anyway, for your specific question:
You’re checking the string "60" for /^.+60,261,420$/.
.+60 will obviously not match because you require at least one character before the 60. The commas also evaluate and are not in your String.
I don’t quite get where your regexp comes from.
Were you looking for a regexp to OR them a hard-coded list of IDs?
Code for splitting it and checking the array of IDs:
findCompany = function(value) {
$('#coName').val().split('::').each(function(val){
if(val == value) return true;
});
return false;
}
$ <- is that jQuery? Within your check-fn: $('#coName').val().split('::').each(function(val){ if(val == value) return true; }); return false;.for(var val in coNameText).
