html - <div> tag to <img> tag Javascript -


hello possible change div tags image tags?

i tried using this

var testdivtags= document.getelementsbyclassname('div_tags'); var testimgtag= document.createelement("img");  (var = 0; < testdivtags.length; ++i) {     testdivtags[i].parentnode.replacechild(testimgtag, testdivtags[i])       }

but doesn't work. ideas?

the problem element can't @ different places in dom simultaneously.

instead, should clone element, , insert clones:

parent.replacechild(newchild.clonenode(), oldchild)

moreover, there problem: htmlcollection returned getelementsbyclassname live. therefore, when replace elements, disappear list, , following ones reindexed lower indices. fix that, can

  • iterate live htmlcollection collection backwards:

    var livec = document.getelementsbyclassname('div_tags'); (var = livec.length-1; >= 0; --i)     livec[i].parentnode.replacechild(testimgtag.clonenode(), livec[i]);

  • convert array:

    var array = [].slice.call(document.getelementsbyclassname('div_tags')); (var = 0; < array.length; ++i)     array[i].parentnode.replacechild(testimgtag.clonenode(), array[i]);

  • use queryselectorall, returns static nodelist collection:

    var staticc = document.queryselectorall('.div_tags'); (var = 0; < staticc.length; ++i)     staticc[i].parentnode.replacechild(testimgtag.clonenode(), staticc[i]);

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.
