javascript - $ ("value") 为空 -> jQuery

Question

我正在尝试使用 jquery form validator 实现客户端验证但我已经按照指南进行操作，并且在谷歌搜索我的问题的答案时也注意到可能与 prototype.js 发生冲突我添加了 var JQuery = jQuery.noConflict(); 到我的 jquery-1.5.1.min.js 文件的底部。

Firebug 还在说 $("#contact") 为空 $("#contact").validationEngine();

我已将所需的 javascript 和 jQuery 代码加载到我的主页 template.php 文件 中，然后调用一个名为 contact 的 view。

联系页面浏览量:

 <section id="content" class="contact-us">
        <h1>Contact</h1>

<div id ="formLayout" class="contactForm">

<section id = "validation"></section>

<form action=contact" method="post" accept-charset="utf-8" id="contact" name="contact">

<fieldset>

<label><label for="name">Name:</label><span class="small">Required Field - Text</span></label>

<input type="text" name="name" value="" id="name" class="validate[required[custom[onlyLetterSp]]]"  />

<div id="error"></div>

<label><label for="email">Email:</label><span class="small">Required Field - yourname@example.com</span></label>

<input type="text" name="email" value="" id="email" class="validate[required[custom[onlyLetterSp]]]"  />

<div id="error"></div>

<label><label for="phone">Phone:</label><span class="small">Required Field - 021214589</span></label>

<input type="text" name="phone" value="" id="phone" class="validate[required[custom[onlyLetterSp]]]"  />

<div id="error"></div>

<label><label for="message">Message:</label><span class="small">Required Field - Text</span></label>

<textarea name="message" cols="90" rows="12" id="message" class="validate[required[custom[onlyLetterSp]]]" >

</textarea><div id="error"></div>

<input type="submit" name="submit" value="Submit"  />

</fieldset>

</form>

</div>  

    </section>
</div>
    <div class="clear"></div>

    <footer>&copy; Housemovers LTD 2011</footer>

    </div> <!-- Wrapper Close -->

     JQuery(document).ready(function(){
      $("#contact").validationEngine();
       });

Answer 1

改成

jQuery("#contact")

.noConflict() 移除了绑定(bind)到 jQuery 的 $
