When developing using jQuery, you may also use other JS libraries, such as Prototype, but conflicts may occur when multiple libraries coexist; if conflicts occur, you can use the following solutions To solve:
1. Import the jQuery library before other libraries and directly use the jQuery (callback) method such as:

test---prototype

test---jQuery

< ;script type="text/javascript">
jQuery(function(){ //Use jQuery directly, there is no need to call "jQuery.noConflict()"Function.
jQuery(" p").click(function(){
alert( jQuery(this).text() );
});
});

$("pp"). style.display = 'none'; //Use prototype

2. The jQuery library is imported after other libraries, and the jQuery.noConflict() method is used to transfer control of the variable $ to other libraries. There are several ways:

<script type="text/javascript">
jQuery.noConflict(); //将变量$的控制权让渡给prototype.js
jQuery(function(){ //使用jQuery
       jQuery("p").click(function(){
              alert( jQuery(this).text() );
       });
});
$("pp").style.display = &#39;none&#39;; //使用prototype
</script>
//代码二
<script type="text/javascript">
var $j = jQuery.noConflict(); //自定义一个比较短快捷方式
$j(function(){ //使用jQuery
       $j("p").click(function(){
       alert( $j(this).text() );
       });
});
$("pp").style.display = &#39;none&#39;; //使用prototype
</script>
//代码三
<script type="text/javascript">
jQuery.noConflict(); //将变量$的控制权让渡给prototype.js
jQuery(function($){ //使用jQuery
       $("p").click(function(){ //继续使用 $ 方法
       alert( $(this).text() );
       });
});
$("pp").style.display = &#39;none&#39;; //使用prototype
</script>
//代码四
<script type="text/javascript">
jQuery.noConflict(); //将变量$的控制权让渡给prototype.js
(function($){ //定义匿名函数并设置形参为$
       $(function(){ //匿名函数内部的$均为jQuery
              $("p").click(function(){ //继续使用 $ 方法
                     alert($(this).text());
              });
       });
})(jQuery); //执行匿名函数且传递实参jQuery
$("pp").style.display = &#39;none&#39;; //使用prototype
/*********************************************************************/
jQuery(document).ready(function(){ //一加载页面的时候就将权利让出去 
       jQuery.noConflict(); 
});
</script>
