ember.js - Obtaining component elementId in parent template -


i obtain component auto-generated elementid in parent template, e.g.

<script type="text/x-handlebars" data-template-name="index">   my-component elementid: {{mycomponentelementid}}   {{my-component}} </script>

is there simple way without altering parent controller or my-component?

elementid being generated during initialization of component. can sure id set after component inserted dom. therefore, can use didinsertelement action this:

some-example elementid: {{mycomponentelementid}} {{some-example elementidproxy=mycomponentelementid}}  didinsertelement: function() {   this.set("elementidproxy", this.get("elementid")); }

thus, proxy elementid via other binding (elementidproxy in situation). recommend not set id explicitly, must unique within app. ember takes care that, it's not idea reinvent wheel.

fully working example in jsbin here

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.
