JQuery: Adding space between multiple selections

I select some paragraphs inside a div:

$('#myDiv p.p1, #myDiv p.p2').text();

My problem is that I want to add space between each selection so that the output is: "paragraph1 (space) paragraph2" i开发者_如何学编程nstead of "paragraph1paragraph2".

Any ideas?

You can use .map() with .get() to create an array of the separate paragraphs, then use .join(" ") to join them together with a space in between.

Try this:

var result = $('#myDiv p.p1, #myDiv p.p2').map(function() {
    return $.text([this]);
    // return this.innerHTML;              // Alternate means of getting text
    // return this.firstChild.nodeValue;   // Another alternate
}).get().join(" ");

The result variable should have your paragraphs with a space separating them.

EDIT: Based on comment from @J-P, updated the text retrieval to be more efficient.

This will do the trick:

$('#myDiv p.p1, #myDiv p.p2').clone().append(' ').text()
