Jquery-UI对话 - 无需DIV即可实现

时间:2011-03-18 16:45:33

标签: jquery-ui html dialog

我怀疑这是一个简单的问题,在搜索之后,我怀疑我的问题的答案是否定的,但要仔细检查...

是否可以使用Jquery ui对话框而无需设置DIV?

即而不是..

$(function() { $( "#dialog" ).dialog();});...

<div id="dialog" title="Do I really need this?">This is a lot of typing just to pass on a simple message</div>

是否有可能只有... ...

$(function(quickly) { $( "#dialog" ).dialog('this would be much easier');});...

并在需要时用quick()类型的东西调用它。

你可能会注意到,我可能会通过Javascript混淆并通过反复试验来找到适用于我的解决方案。

我想,我问我是否可以某种方式以类似的方式使用对话...

alert("this is simple")

...所以我可以在需要时向用户发出提醒,而不是点击网址或按下按钮。

希望上述内容有意义,我怀疑我必须坚持使用丑陋的标准警报,但如果有简单的解决方案,请告诉我。

我希望这对某人有帮助,你可以直接将html传递给对话框,如下所示:

$("<p>Hello World!</p>").dialog(); 

所以这样你就不必拥有预建的div,你可以使用:

$("<div>My div content</div>").dialog();

编辑:将结束标记更改为</div>而非</p>

我正在使用rails并且不喜欢有2个地方可以编写高度依赖的代码。 所以我修改了jquery-ui对话框示例,如下面的代码。请参阅executaDialogModal()

怎么样?

但是你认为添加div正在写很多东西

你不会喜欢这些

答案 3 :(得分:1)

这对我有用。注意为了避免身体被div填充,我确保在关闭后删除使用的div:

$('<div>').prop('id', '_currentDialog').text("Please enter a Comment").dialog(
    {
        title: "Input Error",
        close: function () {
            $('#_currentDialog').remove();
        }
    }
);

您可以创建一个帮助方法,该方法抽象出div的创建和配置,然后调用.dialog()。这至少可以消除重复代码和/或创建多个div的需要。
