     If the position from where you want to 'trim' is known, you could use filter here, like.:

     var a = ['(','C','1','2','3','*',')'] .filter( function(a){ this.x += 1; return this.x<=2 ? a : isNaN(+a);}, {x:-1} );

     Which could lead to this Array extension:

     Array.prototype.trimNumbersFrom = function(n){ return this.filter( function(a){ this.x += 1; return this.x<=n ? a : isNaN(+a); }, {x:-1} );};//=> usagevar a = ['(','C','1','2','3','*',')'].trimNumbersFrom(2); //=> ["(", "C", "1", "*", ")"]

   • Trim +1 out of phone number node.js

     Top Answer

     Answered Jul 08, 2020 · 6 votes

     Since country codes are different (they aren't all +1), I would say that the best way to do this is to trim out the expression where there is a plus sign followed by a number.

     This should do it:

     .replace(/^\+[0-9]/, '');-

     Testing:

     "+12345".replace(/^\+[0-9]/, ''); // 2345"+2345".replace(/^\+[0-9]/, ''); // 345-

     Of course if you only wanted to use the +1, just swap out the [0-9] with a 1.

     You should use .trim() before your .check() like this,

     check('first_name').trim().isLength({ min: 1 }).withMessage('A first name is required')]-

     Hope this helps!

   • Trim string until specified character and also trim suffix

     The easiest way to solve this is by exploding the string into an array. After that you just print the two items you need.

     $string = 'Choose > Apples > Green > Wholesale > 5KG boxes';$stringParts = explode(' > ', $string);$newString = $stringParts[1].' &gt; '.$stringParts[2];-
