This script returns a value like 33 | 4 and I need only the the first whole number, in this case 33.

Can I use .replace( /[^\d].*/, '' ) and where/how to put this? Or is there better solutions?

You are all very helpful, but i'm in a stage where I need to see my full script or a line from it with you solutions implemented ;-)

Thanks

jQuery(document).ready(function($) { $("#input_1_1").blur(function() { // sets the value of #input_1_8 to // that which was entered in #input_1_1 $("#input_1_8").val($("#input_1_1").val()); }); });

    Just call parseInt() on the value. It will read all leading digits until a non-digit character is found: jsfiddle.net/c27xfdoh Commented Mar 26, 2019 at 11:13
  • str.split(/\D+/)[0] Commented Mar 26, 2019 at 11:14
  • use "33 | 4".split('|').map(a=> trim(a))[0] Commented Mar 26, 2019 at 11:14

You can use parseInt() or split your string with | and get the first result

console.log(parseInt("33 | 4")) // or console.log("33 | 4".split(" | ")[0])

In your case you can do 

jQuery(document).ready(function($) { $("#input_1_1").blur(function() { $("#input_1_8").val(parseInt($("#input_1_1").val())); }); });

Try this, 

var str = "33 | 4"; var res = str.split("|");//split with '|' it will return array console.log(res[0].trim());//33

You can do trim on it or parseInt, whatever you want to get your task done.

With split you can split a string with any character, my example:

<script> var stringexample="45.89 | 65"; alert(takefirst(sting)); } function takefirst(){ var a=string.split("|"); return a[0] } </script>

Also you can use split for separete character for character like this

var a=stringexample.split(""); for(var i=0;i<a.lenght;i++){ alert(a[i]); }

Alerts:

4 5 . 8

Etc..

Firstly, please take the time to describe what the issues are and why this solution helps. Remember, we're here to educate people, not just dump code on them. Secondly this will return 3, not 33
