JQUERY: Finding by control ID
提问by OrElse
Currently my aspx page contains
目前我的 aspx 页面包含
<input type="text" name="openid_username" />
<input type="text" name="openid_identifier" />
but now i would like to replace them with
但现在我想用
<asp:TextBox ID="openid_username" runat="server"></asp:TextBox>
<asp:TextBox ID="openid_identifier" runat="server"></asp:TextBox>
so how should i modify the following JQUERY, to reflect the input boxes to textboxes replacement?
那么我应该如何修改以下 JQUERY，以将输入框反映到文本框替换？
var $usr = $this.find('input[name=openid_username]');
var $id = $this.find('input[name=openid_identifier]');

I would use the "ends with" option on the attribute selector in case the name is mangled by the control being in a container. Note the $=instead of =.
我会在属性选择器上使用“ends with”选项，以防名称被容器中的控件破坏。请注意$=代替=。
var $usr = $this.find('input[name$=openid_username]');
var $id = $this.find('input[name$=openid_identifier]');

If you want the exact ID of your controls, you can do this:
如果您想要控件的确切 ID，可以执行以下操作：
var $usr = $this.find('#<%= openid_username.ClientID %>');
var $id = $this.find('#<%= openid_identifier.ClientID %>');
Of course, this is assuming your JS isn't in an external file.
当然，这是假设您的 JS 不在外部文件中。

var $usr = $('[id*=openid_username]');

I'm not sure but if ID translates into the elements ID attribute (i.e turns into <input type="text" id="openid_username">in the aspx generated html, I would go with:
我不确定，但如果 ID 转换为元素 ID 属性（即<input type="text" id="openid_username">在 aspx 生成的 html 中转换，我会选择：
var $usr = $("#openid_username");

I would go with the following to achieve that:
我会采取以下措施来实现这一目标：
