完美解决jQuery符号$与其他javascript 库、框架冲突的问题

<script src="other_lib.js"></script>
<script src="jquery.js"></script>
<script>
 $.noConflict();
 // 之后将只能用 jQuery 进行调用
 jQuery('#message').val();
</script>

<script src="other_lib.js"></script>
<script src="jquery.js"></script>
<script>
$.noConflict();
jQuery( document ).ready(function( $ ) {
 // Code that uses jQuery's $ can follow here.
});
// Code that uses other library's $ can follow here.
</script>

var j = jQuery.noConflict();
 
// Do something with jQuery
j( "div p" ).hide();
 
// Do something with another library's $()
$( "content" ).style.display = "none";
