问题：我不知道为什么我的脚本没有将值加载到表单的选定输入节中
情境： 该页面将其称为主页，永久显示一个带有链接作为内容的对话框。如果用户单击链接另一个对话框，则调用它，打开一个带有表单的“表单对话框”。一些项目通过主机页面的代码 - 平台，浏览器和URL插入到表单中。
这是无效的网址。
在主页上获取URL并将其存储为.data项，以便通过“表单对话框”脚本进行恢复。 我在一个更简单的设置上对此进行了测试，并且它工作得很好但是，它拒绝在当前设置上工作。
症状： URL按预期读取和存储，但脚本不会将其写入表单。我使用的方法是在首次加载对话框时添加回调函数。回调使用.val（）函数将数据写入表单，或者至少是意图。 在对话框设置期间将值写入表单，以便在用户单击时已将信息加载到表单中。
我很感激任何关于问题可能原因和/或纠正方法的指示或建议。
感谢。

我想问的是，如果没有将数据包装在$（document）.ready（）子句中，就会将数据放到主体上。
要快速修复，您可以将url定义为变量，然后在脚本中访问该变量。
示例：
PS： 我建议阅读分离你的PHP代码（使用模板），你的javascript（将它们单独放在.js文件中！）。这将使发现和防止错误变得更容易和易于管理。
