Insert a string at a specific index

Question

How can I insert a string at a specific index of another string?

 var txt1 = \"foo baz\"

Suppose I want to insert \"bar \" after the \"foo

Answer 1

another solution, cut the string in 2 and put a string in between.

var str = jQuery('#selector').text();

var strlength = str.length;

strf = str.substr(0 , strlength - 5);
strb = str.substr(strlength - 5 , 5);

jQuery('#selector').html(strf + 'inserted' + strb);
