如何设置非CSS属性 [英] how to set non-CSS properties
本文介绍了如何设置非CSS属性的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
可以在css文件中设置CSS属性，并将其应用于整个站点。对于输入文本类型，非CSS属性如maxlength如何？我们如何设置它们？
解决方案
我建议使用主题。
1.在网络根目录中添加一个名为app_themes的文件夹（如果它还没有）。
2.在该文件夹中添加名为MyTheme的文件夹。
3.在MyTheme文件夹中添加皮肤文件（右键单击文件夹并选择添加>> ;新项目。来自对话框选择皮肤）。
4.在皮肤文件中输入：
< asp：TextBox runat =''sever''MaxLength =''100''/>
请注意，此处未设置ID等实例变量。
5.在< system.web>下设置的web.config中。添加< page theme =''MyTheme''/>
这将使所有文本框的maxlength = 100.如果只想要一个页面，不要在网络配置中设置它。在页面顶部的@Page指令中，设置theme =''MyTheme''

这些不是属性。它们是属性，与XML属性相同。
显然，你看看HTML标准并写相应的;广义语法类似于XML：< someElement someAttributeName =some sometribite value...> ......。这适用于ASP.NET / HTML。
您可以使用element.setAttribute（）或element.someAttributeName =some sometribite value：

我强烈建议使用jQuery：http://api.jquery.com/category/attributes/ [ ^ ]。

您可以使用全局变量，在_AppStart.cshtml文件中初始化它们，并在需要时调用它们。
尝试在Webmatrix网站的根目录下创建一个新的_AppStart.cshtml文件，其中包含以下内容：
@ {
AppState [ mlen] = < span class =code-digit> 10 ;
}
现在用这个内容创建一个Default.cshtml文件：
@ {
var mlen = AppState [mlen];
}
< html lang = zh >
< < span class =code-leadattribute> body >
< 表格 >
< 输入 type = text maxlength = @ mlen / >
< / form >
< / body >
< / html >
您的输入字段的maxlengh为10，因此您使用属性的任何其他字段maxlength =@ mlen。
CSS properties can be set in a css file and be applied in the whole site. How about non-CSS properties like maxlength for input type of text. How can we set them in general?
解决方案
I would suggest using a Theme then.
1. Add a folder called app_themes in the web root (if it''s not already there).
2. Add a folder called MyTheme in that folder.
3. In the MyTheme folder add a skin file (right click folder and select add>>new item. from dialog select skin).
4. In the skin file put this in:
<asp:TextBox runat=''sever'' MaxLength=''100'' />
Note that no instance variables like ID are set here.
5. In web.config set under <system.web> add <page theme=''MyTheme'' />
This will make all textboxes have maxlength = 100. If you want it only for a single page, don''t set that in the web config. In the @Page directive at the top of the page, set theme=''MyTheme''

Those are not "properties". They are "attributes", same as XML attributes.
Obviously, you look at HTML standard and write the accordingly; generalized syntax is like in XML:<someElement someAttributeName="some attribite value" …> …. This is for ASP.NET/HTML use.
You can add/modify any attribute in JavaScript, usingelement.setAttribute()orelement.someAttributeName = "some attribite value":
http://www.w3schools.com/dom/met_element_setattribute.asp[^].
I would highly recommend to use jQuery: http://api.jquery.com/category/attributes/[^].

You could use global variables, initializing them in the _AppStart.cshtml file an recalling them when you want.
Try to create in the root of your Webmatrix site a new_AppStart.cshtmlfile with the following content:
@{ AppState["mlen"] = 10; }
Now create aDefault.cshtmlfile with this content:
@{ var mlen = AppState["mlen"]; } <html lang="en"> <body> <form> <input type="text" maxlength="@mlen" /> </form> </body> </html>
Your input field has a maxlengh of 10 and so any other field in which you use the attributemaxlength="@mlen".
