如何获取所有生成的行的所有值并将它们放在c#数组中?
答案 0 :(得分:1)
我有一个解决方案,但在我看来它有点hacky。因为你提到c#我假设你正在使用ASP.NET应用程序。如果这就是一种方法:
首先在页面上放置一个不可见的文本框控件。这里重要的是你用css隐藏它。如果将visible属性设置为false,它将不在您的页面上,并且您不能在其中发生任何疼痛。
添加文本框后,您可以创建一个新的jquery函数,该函数会将行的值添加到隐藏的文本框控件中。您可以在“提交”按钮上使用mousedown事件进行操作,也可以随时随地进行“更改”事件。
您要做的最后一件事是您必须将分隔符添加到行值,您可以将它们拆分回c#中的数组。
文本框控件的值最终会如下所示:
ValueRow1|ValueRow2|ValueRow3
回到c#,很容易将值拆分成数组:
string[] myArr = textbox1.Text.Split('|');
