如何判断jquery ui对话框查询是否已初始化? [英] How can I tell if a jquery ui dialog query has been initialized?

问题描述

我有以下代码来检测jquery ui对话框是否打开:

I have the following code to detect if a jquery ui dialog is open:

if ($("#dialog-myDialog").dialog("isOpen")) {
      return;
}

可以正常工作，但是我发现这种情况是在首先初始化对话框之前调用此代码的，而在这种情况下，此if语句似乎就被炸掉了.

which works fine but I found a situation where this code get called prior to the dialog being initialized in the first place and this if statement seems to just blow up in this case.

检查jquery ui对话框是否已初始化的最佳方法是什么，以便我可以正确处理这种情况.

What is the best way to check if a jquery ui dialog has been initialized so I can properly handle this situation.

推荐答案

测试元素是否具有ui-dialog-content类:

if ($("#dialog-myDialog").hasClass("ui-dialog-content") &&
    $("#dialog-myDialog").dialog("isOpen")) {
    return;
}
