Question

I’m having real difficulty with this but I’m no javascript expert. All I want to do is get myself an array of all matches in a string which match a given regExp. The regExp being this :

[0-9]+

ie. Any integer.

So If I pass the string “12 09:8:76:::54 12” I should get

arr[0]=”12″
arr[1]=”09″
arr[2]=”8″
arr[3]=”76″
arr[4]=”54″
arr[5]=”12″

Easy? Not for me! I could do this in vb.net no problem with regexp.matches(string) (something like that anyway). I thought that the javascript method .exec would also give me an array however it only returns the first match. What’s going on? Code…

function testIt(){
    splitOutSelection2("123:::45  0::12312 12:17"); 
}


function splitOutSelection2(sSelection){
    var regExp = new RegExp("[0-9]+","g");
    var arr = regExp.exec(sSelection);
}; 

Answer 1

All the answers work but I was wanting to keep my regExp object rather than specify it at the time of use. So simply changing the function to…

function splitOutSelection2(sSelection){
    var regExp = new RegExp("[0-9]+","g");
    var arr = sSelection.match(regExp);
}; 

..is what I was looking for. Thanks for pointing me in the right direction though to all who have replied.
