$("<style> go here ???? { display: none; }</style>").appendto(document.documentelement);

how can select list item iconsrc="/_layouts/15/images/delitem.gif" document.

<div class="ms-core-menu-box ms-core-menu-hasicons ms-core-defaultfont ms-shadow" title="" dir="ltr" contenteditable="false" style="top: 0px; position: absolute; visibility: visible; left: -129px; width: 127px;" flipped="false">     <ul class="ms-core-menu-list">         <li type="option" text="delete" onmenuclick="spgridcontainer_wpq2_rowcontextmenu_onclick(0);" iconsrc="/_layouts/15/images/delitem.gif" iconalttext="delete" enabled="true" checked="undefined" id="mp43_0_0" class="ms-core-menu-item">             <a class="ms-core-menu-link" id="mp43_0_0_anchor" href="javascript:;" onclick="return false;" title="delete">                 <div class="ms-core-menu-icon">                     <img src="/_layouts/15/images/delitem.gif" alt="delete" title="delete" id="mp43_0_0_icon">                 </div>                 <div class="ms-core-menu-label" id="">                     <span class="ms-core-menu-title">delete</span>                     <span></span>                 </div>                 <span class="ms-accessible"></span>                 <div></div>             </a>         </li>     </ul> </div>

point keep delete button hidden whenever list injected in page.

keep simple css attribute selectors:

li[iconsrc="/_layouts/15/images/delitem.gif"] {      display:none;  }
<ul>      <li iconsrc="/_layouts/15/images/delitem.gif">          <img src="/_layouts/15/images/delitem.gif" alt="delete" title="delete" id="mp43_0_0_icon" />      </li>      <li>          <img src="/_layouts/15/images/adasdasfafsdfs.gif" alt="sdfsdfsdf" title="blablalbavbaab" id="fsdfsdfsdf"/>      </li>  </ul>

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.
