检测单击了哪个提交按钮 [英] Detect which submit button was clicked
问题描述
我知道这个问题听起来很像其他问题，但是我发誓我在任何地方都找不到合适的解决方案.我有一个具有多个提交按钮的旧式表单.如果单击，则需要做一些客户端验证，并可能停止提交.如果单击另一个，则不需要进行此验证.
I know this question sounds a lot like a bunch of others that are out there, but I swear I can't find the right solution anywhere. I have a legacy form that has multiple submit buttons. If one is clicked, I need to do a bit of client-side validation and potentially stop the submit. If the other is clicked, I don't need to do this validation.
我发现的是，如果创建一个.submit()处理程序，我似乎无法访问实际单击了哪个按钮.另一方面，如果捕获了我需要担心的按钮的.click()事件，那么我不能阻止表单通过.preventDefault()(或.stopImmediatePropagation())提交.
What I'm finding is that if I create a .submit() handler, I can't seem to access which button was actually clicked. On the other hand, if I capture the .click() event of the button I need to worry about, then I can't prevent the form from submitting via .preventDefault() (or .stopImmediatePropagation()).
这是尝试使用按钮.click()处理程序的代码的最新迭代:
Here's the most recent iteration of the code that attempts to use the buttons .click() handler:
$('#nextButton').click( function( e ) {
e.preventDefault(); // The form submits anyway (which kind of makes sense)
// return false also doesn't prevent the submission
// If any session question is unanswered, abort
/* $('#registrants input:text[id$="Answer"]').each( function( i, input ) {
if( $.trim( $(input).val() ) == '' ) {
submit = false;
}
});*/
});
我在这里想念什么?有一种方法可以做到这一点，而且看起来应该很简单，但是如果我有运气的话，我该死的.
What am I missing here? There has to be a way to do this and it seems like it should be fairly simple, but I'll be damned if I've had any luck at all.
谢谢.
推荐答案
基本上说的是在表单commit()处理程序中检查按钮ID.
Basically what it says is to check the button ID in the form submit() handler.
