Question

我正在开发一个带有primefaces 5的项目，一个页面使用需要jquery的js文件，但显示Uncaught TypeError: undefined is not a function，但当我将jquery源从<h:outputScript library="primefaces" name="jquery/jquery.js" target="head"/>更改为

时

<h:head>
    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js"></script>
      <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.10/jquery-ui.min.js"></script>
</h:head>

工作正常，但我失去了许多主要功能，如contexMenu

我该如何解决这个冲突？

这是我的javascript文件：

(function($, $S) {
//$ jQuery
//$S window.localStorage
//Variables Declaration
var $board = $('#notesForm\\:board'),
//Board where the Posticks are sticked
Postick, //Singleton Object containing the Functions to work with the LocalStorage
len = 0, //Length of Objects in the LocalStorage
currentNotes = '', //Storage the html construction of the posticks
o; //Actual Postick data in the localStorage

//Manage the Posticks in the Local Storage
//Each postick is saved in the localStorage as an Object 
Postick = {
    add : function(obj) {
        obj.id = $S.length;
        $S.setItem(obj.id, JSON.stringify(obj));
    },

    retrive : function(id) {
        return JSON.parse($S.getItem(id));
    },

    remove : function(id) {
        $S.removeItem(id);
    },

    removeAll : function() {
        $S.clear();
    }

};

//If exist any postick, Create it/them
len = $S.length;
if (len) {
    for (var i = 0; i < len; i++) {
        //Create all posticks saved in localStorage
        var key = $S.key(i);
        o = Postick.retrive(key);
        currentNotes += '<div class="postick"';
        currentNotes += ' style="left:' + o.left;
        currentNotes += 'px; top:' + o.top;
        //data-key is the attribute to know what item delete in the localStorage
        currentNotes += 'px"><div class="toolbar"><span class="delete" data-key="'
                + key;
        currentNotes += '">x</span></div><div contenteditable="true" class="editable">';
        currentNotes += o.text;
        currentNotes += '</div>';
    }

    //Append all the posticks to the board
    $board.html(currentNotes);
}

//When the document is ready, make all posticks Draggable
$(document).ready(function() {
    $(".postick").draggable({
        cancel : '.editable',
        "zIndex" : 3000,
        "stack" : '.postick'
    });
});

//Remove Postick
$('span.delete').live('click', function() {
    if (confirm('Are you sure you want to delete this Note?')) {
        var $this = $(this);
        //data-key is the attribute to know what item delete in the localStorage
        Postick.remove($this.attr('data-key'));
        $this.closest('.postick').fadeOut('slow', function() {
            $(this).remove();
        });
    }
});

//Create postick
$('#notesForm\\:btn-addNote')
        .click(
                function() {
                    $board
                            .append('<div class="postick" style="left:20px;top:70px"><div class="toolbar"><span class="delete" title="Close">x</span></div><div contenteditable class="editable"></div></div>');
                    $(".postick").draggable({
                        cancel : '.editable'
                    });
                });

//Save all the posticks when the user leaves the page
window.onbeforeunload = function() {
    //Clean the localStorage
    Postick.removeAll();
    //Then insert each postick into the LocalStorage
    //Saving their position on the page, in order to position them when the page is loaded again
    $('.postick').each(function() {
        var $this = $(this);
        Postick.add({
            top : parseInt($this.position().top),
            left : parseInt($this.position().left),
            text : $this.children('.editable').text()
        });
    });
}
})(jQuery, window.localStorage);

PrimeFaces是一个基于jQuery的JSF组件库已经附带了jQuery（和UI）。一旦在页面上使用PrimeFaces组件，PrimeFaces就会自行加载它们。绝对没有必要手动加载其他jQuery文件。它只会在你遇到的所有颜色上发生冲突。

如果您真的想在不一定包含PrimeFaces组件的页面上使用jQuery / UI，因此jQuery / UI不一定会自动包含，那么您需要手动包含PrimeFaces捆绑的jQuery，如下所示：

<h:outputScript library="primefaces" name="jquery/jquery.js" target="head" />
<h:outputScript library="primefaces" name="jquery/jquery-plugins.js" target="head" />

注意：这不会以重复包含的方式结束。 JSF / PrimeFaces能够检测到您已经手动声明了它们，并且不会自动包含另一个。

或者，如果您确实想将 PrimeFaces捆绑的jQuery / UI升级到更新版本，请将这些文件放在完全以下位置和文件名：< / p>

WebContent
 |-- resources
 |    `-- primefaces
 |         `-- jquery
 |              |-- jquery.js          <-- newer jQuery version
 |              `-- jquery-plugins.js  <-- newer jQuery UI version
 :

当在WAR而不是JAR中找到JSF资源时，WAR中的那些资源将比JAR中的资源具有更高的加载优先级。

如果您仍然遇到Uncaught TypeError错误，请确保您在Internet中找到的jQuery代码段与PrimeFaces捆绑的jQuery版本兼容。 PrimeFaces 5.0附带jQuery 1.11.0和jQuery UI 1.10.3。你的代码片段似乎是针对jQuery 1.4而且很多已经在jQuery 1.11的路径中被更改了。例如，$.live()在1.7中已弃用，在1.9中已删除。另请参阅the documentation。

我也喜欢你的问题。请确保script声明如下例所示。不要使用$(....)唱歌。使用jQuery(...)。对我来说没关系。

<h:head>
    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js"></script>
    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.10/jquery-ui.min.js"></script>
    <h:outputScript library="primefaces" name="jquery/jquery.js" target="head"/>
    <script type="text/javascript">
        jQuery(document).ready(function(jQuery){

            ..don't use $

        });
    </script>       
</h:head>
