如果否:

::-webkit-input-placeholder {
   text-align:center;
}
:-moz-placeholder { /* Firefox 18- */
   text-align:center;  
}
::-moz-placeholder {  /* Firefox 19+ */
   text-align:center;  
}
:-ms-input-placeholder {  
   text-align:center; 
}

您可以根据需要将图标放置在中间，但是键入时它不会消失，所以我认为这没有意义.但是，如果您喜欢:

You can place the icon in the center if you like, however it does not disappear when you type, so I think it does not make sense. But if you like:

.ui-input-search:after{
   width:18px;
   height:18px;
   left: 50%;
   margin-left: -50px;
}
