jQuery验证触发器错误消息 [英] jQuery validation trigger error message

问题描述

我有一个奇怪的问题.我想在元素上触发jquery-valdation错误消息，即使它是有效的.

I have a kinda wierd problem. I want to trigger a jquery-valdation errormessage on an element even thou it's valid.

场景: 我有一个大表格.输入之一是用于PersonalId.输入该PersonalId是可选的. 除了输入，我还有一个普通按钮(不是提交按钮).如果单击该按钮(从ajax获取信息)，而PersonalId字段为空，则我想触发该错误消息.

Scenario: I have a large form. One of the inputs is for PersonalId. It's optional to enter that PersonalId. Beside that input i have a normal button (not the submit-button). If you click on that (fetching information from ajax) and the PersonalId field is empty i want to trigger that Error-message.

使用jQuery Validate是否可行?还是需要创建自己的函数?

Is that possible with jQuery Validate or do i need to create my own function?

两者都是.您可以使用showErrors函数在表单上手动显示错误，但是由于您不希望在提交表单时启用此规则，因此您必须执行您自己检查输入中的值.

Both, sort of. You can use the showErrors function to display errors on the form manually, but since you don't want this to be a rule that is enabled when you submit the form, you'll have to do your own checking for the value in the input.

类似的东西:

var $validator = $("#myform").validate();
$("#checkid").click(function() {
    var errors;

    if (!$("#personalid").val()) {
        /* Build up errors object, name of input and error message: */
        errors = { personalid: "Please enter an ID to check" };
        /* Show errors on the form */
        $validator.showErrors(errors);            
    }        
});

请注意，如果personalid字段中没有任何内容，表单仍将提交.

Note that the form will still submit if there is nothing in the personalid field.
