单击提交按钮的值

问题描述

这应该很简单.

我正在检查是否正在使用jquery提交表单.表单具有多个带有不同值的提交按钮:

I'm checking if a form is being submitted using jquery. The form has multiple submit buttons with various values:

<button type="submit" value="foo">Foo</button>
<button type="submit" value="bar">Bar</button>

我想找到刚刚提交表单的按钮的值:

I would like to find the value of the button that just submitted the form:

$(form).live('submit', function() {
    // Get value of submit button
}

谢谢

推荐答案

绑定该事件以提交按钮而不是表单，然后$(this)将引用按钮...

Bind the event to submit buttons instead of the form and then $(this) would have the reference to the buttons...

$(":submit").live('click', function() {
    alert($(this).val());
})

编辑:自jQuery 1.7起，不推荐使用 live . 改用上.

EDIT As of jQuery 1.7 live is deprecated. Use on instead.

$(document).on("click", ":submit", function(e){
    alert($(this).val());
});
