我需要一个解决方案来警告主从场景中未保存的更改。我能够实现 Sam 在 2015 年 9 月创建的解决方案 ( http://www.samjhill.com/blog/?p=525#comment-28558 )。这是对链接 Detect Unsaved changes and alert user using angularjs 上的 stackoverflow 问题和答案的回应。 .
Sam 提供的解决方案非常适合 html 文件中的单个表单,但在标题部分和详细信息部分中有多个表单(两者都可以更改)的情况下,我遇到了问题。在详细信息部分,我使用 xeditable 表。我尝试将“退出时确认”属性添加到这两种表单中。在顶部,确认框按预期出现,但即使在我提交更新后仍继续出现。在可编辑部分,确认框永远不会出现。我已经在下面包含了我的 html。您能否提供我可以提出的任何建议,以便在对页面上的任何表单进行更改时出现警告?.container.col-md-12.col-sm-12.col-xs-12-center

最佳答案
因为我不知道 HTML 存在嵌套表单元素的问题,所以这是一个很好的提示。我删除了按钮表单,并将“创建/更新/删除”按钮作为标题表单的一部分。然后,我将表单名称传递给函数来创建、更新和删除记录。在函数中我添加了代码: myForm.$setPristine(true); myForm.$setSubscribed(true); myForm.$setDirty(false); 在 xeditable 表单中,我还将主表单的名称传递给 onbeforesave='changeAnswers(headerForm)'。在changeAnswers函数中我添加了代码: myForm.$setDirty(true);
到目前为止,工作进展顺利。
