Numeric Regex Expression for Detection Using Javascript -


i new regex hence long question. know regex expression codes detect different types of numbers in html paragraph tag.

  1. integer number (eg: 0 , 1,000 , 1000 , 028, -1 , etc)
  2. floating number (eg: 2.3 , 2.13 , 0.18 , .18 , -1.2 , etc)

or regex can combine both 1. & 2. -- integer , float number good! tried solution in stackoverflow results undefined/null, else not detectable already

  1. ratio (eg: 1:3:4 detect whole if possible)
  2. fractional number (eg: 0/485 , 1/1006 , 2b/3 , etc)
  3. percentage number (eg: 15.5% , (15.5%) , 15% , 0.9%, .9%)

also, know if regex can detect symbols , numbers together in whole (15.5% , 1:3:4), or must split different parts before detection of number can performed (eg: 15.5 + % , 1 + : + 3 + : + 4 ) ?

these different expressions meant written javascript code different exceptions of cases later on. expressions planned used regex detects basic integer in attached javascript snippet below:

    var paragraphtext = document.getelementbyid("detect").innerhtml;     var allnumbers = paragraphtext.match( /\d+/g ) + '';     var numbersarray = allnumbers.split(',');      (i = 0; < numbersarray.length; i++) {          //console.log(numbersarray[i]);         numbersarray[i] = "<span>" + numbersarray[i] + "</span>";         console.log(numbersarray[i]);     }      });

thank help!

the following simple implementations:

'2,13.00'.match(/[.,\d]+/g) // 1 & 2 '1:3:4'.match(/[:\d]+/g) // 3 '0/485'.match(/[\/\d]+/g) // 4 '15.5%'.match(/[.%\d]+/g) // 5

you can loop through them using for statement, , check if 1 detected , break, or continue otherwise.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
