I am trying to get a variable number out of a text in the below example is the text.

Koop 5 voor € 16,00 p/s en bespaar 11%
Koop 50 voor € 15,00 p/s en bespaar 17%
Koop 120 voor € 13,00 p/s en bespaar 28%
Koop 1000 voor € 10,00 p/s en bespaar 45%

This means Buy X for $Y each and save Z%

I need X out of this text with jQuery or Javascript.

Below is the code, to get the text out of the A tag

 $(function(){
    $('.link').click(function() {
        $("#input-field").val($(this).html());
    });
});

and the example a tags and input field:

<input id="input-field" type="text">

<a href="#" class="link">koop 10 voor 10 p.s.<a>
<a href="#" class="link">koop 110 voor 9 p.s<a>
<a href="#" class="link">koop 950 voor 7 p.s<a>

• javascript
• jquery
• html
• regex

• 4 And what's the regex you've tried? – Bergi Commented Jun 27, 2013 at 12:52
• What is the text really now? Your two example sets look very different. Or should the regex cope with all of them? – Bergi Commented Jun 27, 2013 at 12:54
• What do you mean with character size? If you split on the first space, in both examples it is the second element in the resulting array (index 1). – 11684 Commented Jun 27, 2013 at 12:58
• 10,100,1000,10000 eventually. So it should get all the numbers after Koop till the next space I guess. – Nick N. Commented Jun 27, 2013 at 12:58
• You are right, that would probably work, upvote if you answer it – Nick N. Commented Jun 27, 2013 at 12:59

With regex you can do this:

$("#input-field").val( $(this).html().match(/\d+/)[0] );

...that is, select the first digit or digits in the string using /\d+/, where .match() returns an array so you need to grab the first (and only) element in the array.

Demo: http://jsfiddle/WnruN/

Or you can just use .split():

$("#input-field").val( $(this).html().split(" ")[1] );

That is, select the second "word" (in your case a number).

Demo: http://jsfiddle/WnruN/1/

Note that if you make your regex global by adding the g flag - /\d+/g - then .match() will return an array of all of the numbers in the input string: http://jsfiddle/WnruN/2/ (If you want to allow for numbers with mas like in your first example use /[\d,]+/g: http://jsfiddle/WnruN/3/)

you can try this one.

var temp=$(".link").split(" ");
alert(temp[1]);                //it will give you 5 or 50 or 120 or 1000

Please let me know if you want further help.
