javascript - JS: Set Background on hovered items -


i have 6 <p> tags on site , want x have different color when it's hovered:

html: 

<p>a<span class="del">x</span></p> <p>b<span class="del">x</span></p> <p>c<span class="del">x</span></p> <p>d<span class="del">x</span></p> <p>e<span class="del">x</span></p> <p>f<span class="del">x</span></p>

js:

function func(elem) {     'use strict';     elem.style.backgroundcolor = "red"; }  var spans = document.getelementsbyclassname("del"); var i; (i = 0; < spans.length; = + 1) {     spans[i].onmouseover = func(spans[i]); }

but code every x has red background, if don't hover on anything. have change?

use .addeventlistener() have placed loop function called events(). called when page ready. 

function func() {     this.style.backgroundcolor = "red";  }  function events(){  var spans = document.getelementsbyclassname("del");  var i;  (i = 0; < spans.length; = + 1) {  	spans[i].addeventlistener('mouseover',func,false);  }  }  window.onload=events;
<p>a<span class="del">x</span></p>  <p>b<span class="del">x</span></p>  <p>c<span class="del">x</span></p>  <p>d<span class="del">x</span></p>  <p>e<span class="del">x</span></p>  <p>f<span class="del">x</span></p>

if have questions, please leave comment below , possible.

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.
