jQuery验证生成的ID [英] Jquery Validate with generated id's

问题描述

我创建了一个表，该表将进行AJAX搜索汽车登记并将信息返回到表中.

I have created a table that will do an AJAX search for a car registration and return the information to a table.

然后将添加一个带有文本框的新行.每个文本框都有一个唯一的名称& id例如[0] .r_make/[1] .r_model一切正常，但是当我单击按钮时，该按钮无效.

this then will add a new row with textboxes. Each textbox has a unique name & id e.g. [0].r_make / [1].r_model everything is all working except when I click the button it doesn’t validate.

发生的事情是，它在下一行发布了空白字段. 我没有关于如何验证这一点的想法. 一些帮助，将不胜感激.

What happens is, it posts the next row with empty fields. I am running out of ideas on how to validate this. Some help would be appreciated.

我尝试过标准.valid()，但是它是css附带的，但是仍然可以处理按钮单击，在空字段时也考虑禁用按钮，但是我正在努力使它与唯一的生成ID一起工作

I have tried standard .valid() but it comes up with the css but still processes the button click, have also looked into disableing the button when there is an empty field but i am struggling getting this working with the unique generated id's

推荐答案

如果我清楚理解您的意思(由于缺乏信息，我可以说这有点困难；-))，则将创建一个新的文本框结果作为AJAX调用，并生成了name/id.此文本框充当用户的容器，用户可以输入您需要再次验证预定义规则集的内容

If I understand clearly what you mean (and I can tell it's a bit hard due to lack of information ;-) ), a new textbox is created as a result as an AJAX call, with generated name/id . This textbox serve as a container for the user which can input something that you need to validate again a predefined set of rules

您必须记住，在表单上应用validate方法时，新来者复选框不属于DOM.然后验证插件不知道

You have to remember that your newcomer checkbox wasn't part of the DOM at the time you applied the validate method on your form. It's then unknown to the validation plugin

请检查验证插件的动态表单演示，并研究代码，尤其是以delegate

Please check the dynamic form demo of the validation plugin and study the code, especially the part which begins with delegate
