jQuery-使用按钮禁用和启用表单元素

问题描述

大家好，在此先感谢您的帮助.这是我的代码:

Hey all, thanks in advance for the help.This is my code:

$(document).ready(function () {
    $("#showexistingcust").button().click(function () {
        $('#newcust :input').attr('disabled', 'disabled');
        $('#newcust :select').attr('disabled', 'disabled');
        $('#existingcust :input').removeAttr('disabled');
        $('#existingcust :select').removeAttr('disabled');
    })

    $("#showaddcust").button().click(function () {
        $('#existingcust :input').attr('disabled', 'disabled');
        $('#existingcust :select').attr('disabled', 'disabled');
        $('#newcust :input').removeAttr('disabled');
        $('#newcust :select').removeAttr('disabled');
    })
});

我对jquery还是很陌生，所以我可能缺少一些基本知识.但这似乎有些奇怪的行为.根据我对代码的订购方式，removeAttr函数要么根本不运行，要么仅按一个按钮/div工作.

I'm pretty new to jquery, so I might be missing something basic. But this seems to have some odd behavior. Depending on how I order to the code, the removeAttr functions either dont run at all, or just work on one button/div.

我不知道为什么会这样，有人能够阐明一些想法吗?

I have no idea why this is so, anybody able to shed some light?

HTML:

<div id="newcust">
<label for="surname" class="left">Surname</label>
<input type="text" name="surname" id="s_name" class="required" /><br />

<label for="p_name" class="left">Personal Name</label>

<input type="text" name="p_name" id="p_name" class="required"/> <br />

<label for="m_phone" class="left">Mobile Phone</label>
<input type="text" name="m_phone" id="m_phone" class="digits"/> <br />

<label for="h_phone" class="left">Home Phone</label>
<input type="text" name="h_phone" id="h_phone" class="digits"/> <br />

<label for="w_phone" class="left">Work Phone</label>
<input type="text" name="w_phone" id="w_phone" class="digits"/> <br />

<input type="text" name="email" id="email" class="email" /> <br />

<label for="address1" class="left">Addresss</label>

<label for="state" class="left">State</label>
<input type="text" name="state" id="state" class="required" maxlength="3"/> <br />

<option value="credit">Credit Card</option>
</select> <br />
<label for="promo" class="left">Promotional Material</label>
<input type="checkbox" name="promo" value="1" /><br />
</div>

<div id="existingcust">
<label for="searchc">Search</label>
<input type="text" name="searchc" id="searchc_box" class='searchc_box'/>
<input type="submit" value="Search" class="searchc_button" id="searchc_button" /> <br />
<label for="c">Results</label>
<select name="custlist" id="custlist" class="required">
</select>
</div>

推荐答案

您可以通过省略对select元素(:input 选择器匹配select以及input，textarea和button元素.尝试从处理程序中返回false，以防止其采取默认操作(我假设这些是在按钮中添加的定位标记).

You can simplify this by omitting the actions on select elements, the :input selector matches select as well as input, textarea, and button elements. Try returning false from the handler to prevent it from taking the default action (I assume these are anchor tags being made into buttons).

$(document).ready(function () {
    $("#showexistingcust").button().click(function () {
        $('#newcust :input').attr('disabled', 'disabled');
        $('#existingcust :input').removeAttr('disabled');
        return false;
    })

    $("#showaddcust").button().click(function () {
        $('#existingcust :input').attr('disabled', 'disabled');
        $('#newcust :input').removeAttr('disabled');
        return false;
    })
});
