jquery - Jstree not displaying tree -


i trying populate div jstree using json. div, before attempted population looks this:

    <div id="maintree">      </div>

the jsontree variable, holds tree, looks (as string. code passes original json object):

"{\"core\":{\"data\":[{\"id\":\"123323\",\"parent\":\"#\",\"text\":\"123323\"},{\"id\":\"54366\",\"parent\":\"#\",\"text\":\"54366\"},{\"id\":\"634766\",\"parent\":\"#\",\"text\":\"634766\"}]}}"

the tree populated this:

$('#maintree').jstree(jsontree);

after script div looks this, content not there. wrong?

<div class="treecontainer" id="treecontainer">         <input class="treesearch" id="treesearch" type="text" placeholder="search" value="">         <div tabindex="0" class="jstree jstree-1 jstree-default jstree-leaf" id="maintree" role="tree" aria-busy="false" aria-multiselectable="true" aria-activedescendant="j1_loading"><ul class="jstree-container-ul jstree-children" role="group"></ul></div>     </div>

edit: trying populate tree directly, example jstree, not work either. population done in separate file, imported index.html (last on page).

    $('#maintree').jstree({         'core': {             'data': [                 { "id": "ajson1", "parent": "#", "text": "simple root node" },                 { "id": "ajson2", "parent": "#", "text": "root node 2" },                 { "id": "ajson3", "parent": "ajson2", "text": "child 1" },                 { "id": "ajson4", "parent": "ajson2", "text": "child 2" }             ]         }     });

the index.html partially looks (where websocket-handling.js sets maintree).

<html> <head> ... </head> <body> ...     <script src="js/jstree.min.js"></script>     <script src="js/websocket-handling.js"></script> </body>

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.
