jquery - Get H3 and build link with ID -


i'm trying h3 elements on page build links , create dynamic summary.

so here's have :

$('h3').attr('id', function() {     return this.innerhtml; });  $('h3:not(:last)').append(" › "); var headers = $('h3').text();  $('.summary').append(headers);

i have : header1 › header2 › header3 › header4

but don't know how use id of each h3 elements , build links have : 

<a href="header1">header1</a> › ...

thank help.

regards.

edit : problem " › " added in h3 , not in summary...

you should use jquery's .each() function, this:

$(document).ready(function() {   $('h3').each(function(index) {     var id = $(this).attr('id');     var text = $(this).text();      var spacer = index ? ' > ' : ''; // don't show spacer first item     var header = spacer + '<a href="#' + id + '">' + text + '</a>';      $('.summary').append(header);   }); });

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
