第一个元素将错误信件到焦点。 Javascript
原标题:The first element will error message to go on focus. Javascript

我有一个带有一些输入字段的表格 :

Folder Name:
<input type="text" id="folderName" name="folderName" data-bind = "value: FolderName" />

Prefix:
<input id="prefix" name="prefix" data-bind = "value: Prefix" />

我使用jquery 验证插件验证这些字段:

rules: {
            folderName: {
                required: true
            },
            prefix: {
                required: true,
                exactLength: 4
            },
}

在提交带有空字段的窗体时,要为两个输入显示错误信息。我要完成的是第一个带有错误信息的内容,以便继续关注。我的javascript技术非常差,因此任何工作范例都将非常感激。谢谢!

在你的验证火灾发生后 像这样掉下来的东西

// set focus to first input
$( body ).find( :input:first ).focus();
