How to trigger validation before submission in parsley?
提问by Sefier Tang
I'm now using parsley 2 to validate my form, it works fine except this problem: only after you submit your form for the first time, the validation will be triggered when you change your input, but before submission, it will do nothing.
我现在正在使用 parsley 2 来验证我的表单，它工作正常，除了这个问题：只有在您第一次提交表单后，当您更改输入时才会触发验证，但在提交之前，它什么都不做。
That said, I want to trigger validation before the first submission. How can I achieve this?
也就是说，我想在第一次提交之前触发验证。我怎样才能做到这一点？

You'll need to use data-parsley-trigger="keyup"(http://parsleyjs.org/doc/index.html#psly-ui-for-form) if you want that your fields auto-validates on keyup event.
如果您希望您的字段在 keyup 事件上自动验证，您将需要使用data-parsley-trigger="keyup"( http://parsleyjs.org/doc/index.html#psly-ui-for-form)。
You could define it field by field, or on the whole form is directly in the <form>tag.
您可以逐个字段定义它，或者在整个表单上直接在<form>标签中定义。
