问题描述

您好，我现在有一个带有2个复选框和一个按钮的表单，我需要做的是，如果用户在我们选中任何可用复选框的情况下单击按钮，我想显示自定义警告，说选择一个 ..如果选择了一个，我不想显示警报...

进行了一些更改，如下所示

Hi all I am having a form with 2 check-boxes and a button what I need to do is if the user clicks on a button with our checking any check-box available, I would like to show custom alert saying select one.. If one is selected I don''t want to show the alert...

for this I used the following

http://www.abeautifulsite.net/blog/2008/12/jquery-alert-dialogs/[^]

with some changes as follows

<script type="text/javascript">

        $(document).ready(function () {
            var atLeastOneIsChecked = $('#checkArray :checkbox:checked').length > 0;

            if (atLeastOneIsChecked == 0) {
                $("#alert_button").click(function () {
                    jAlert('This is a custom alert box', 'Alert Dialog');
                });
            }
        });

    </script>

<form id="form1" runat="server">
    <fieldset id="checkArray">
    <input type="checkbox" name="chk[]" value="Apples" />
    <input type="checkbox" name="chk[]" value="Bananas" />
</fieldset>
        <p>
            <input id="alert_button" type="button" value="Show Alert" />
        </p>
    </form>

但是我对这两种情况都保持警惕，任何人都可以帮助我..

推荐答案

(document).ready(function(){ var atLeastOneIsChecked =

(document).ready(function () { var atLeastOneIsChecked =

('#checkArray:checkbox:checked').length> 0; if(atLeastOneIsChecked == 0){

('#checkArray :checkbox:checked').length > 0; if (atLeastOneIsChecked == 0) {

(#alert_button").click(function(){ jAlert('这是一个自定义警报框'，'Alert Dialog')； }); } }); < /script >

("#alert_button").click(function () { jAlert('This is a custom alert box', 'Alert Dialog'); }); } }); </script>

<form id="form1" runat="server">
    <fieldset id="checkArray">
    <input type="checkbox" name="chk[]" value="Apples" />
    <input type="checkbox" name="chk[]" value="Bananas" />
</fieldset>
        <p>
            <input id="alert_button" type="button" value="Show Alert" />
        </p>
    </form>
