是小提琴为你工作与文本框？ – 2013-05-13 08:29:58

是的...但是当我尝试使用代码的文本区域，那么它不工作..你可以看到链接来验证.. – Lucy 2013-05-13 08:32:20

你试过'$（“textarea：eq（”+（index）+ “）”）'？ – 2013-05-13 08:33:29

检查样品 http://jsfiddle.net/RbenU/10/

为如下选择，而不是输入使用的textarea

if (serieI == 0) { 
     comment = $("textarea:eq(" + (index) + ")").val(); 
} else { 
     //comment = "second serie matched!"; 
     comment = $("textarea:eq(" + (index1) + ")").val(); 
}

如果我在Jquery UI自定义对话框中显示文本区域以从用户获取输入并显示工具提示，请问这项工作吗？ – Lucy 2013-05-13 09:06:08

@Lucy：是的，它会工作，但需要使用适当的选择器来定制对话框和textarea。 :) – vijay 2013-05-13 09:44:41

您可以更改input到:input：

comment = $(":input:eq(" + (index) + ")").val(); 
comment = $(":input:eq(" + (index1) + ")").val();

@Archer'：input'可以选择所有表单元素，我希望你知道它。 – Jai 2013-05-13 08:40:33

如果我在Jquery UI自定义对话框中显示文本区域以从用户获取输入，然后显示工具提示，请问这是否工作？ – Lucy 2013-05-13 09:08:17
