Question

谁能帮助我理解这一分类法?

$(this).find( input[type="submit"]:not(.cancel), button ).click(function ()

I m对.cancel特别感兴趣,因为如果用户点击取消的纽顿,则用于验证一个页,而Im试图阻止验证。我猜测上述编码线,他说,被点击的纽特是取消的纽特,然后继续。

但我不知道如何指定一个州为取消。

Answer 1

Basically it is looking for elements located within this that has the following requirements

is an input
has type = submit
does not have a class of cancel

页: 1

is a button

Answer 2

这方面的良好答案。或许这一附加说明的文本增加了一些价值。

$(this)                   // within this jQuery object
  .find(                  // find all elements
    input[type="submit"]  // that are input tags of type "submit"
    :not(.cancel)         // and do not have the class "cancel"
    ,                     // or
    button                // are button elements
   )
  .click(                 // and for each of these, to their click event
    function (){}         // bind this function
  );

Answer 3

They re applying a CSS class named cancel to symbolize the cancel button basically (then checking it s a button with out this class)

~~Though 我不知道你可以使用星号(*)的星号。~~

Nevermind, 是你试图在代号范围内制定大胆的法典:。

我也奇怪的是,他们为什么要取消任何途径,就提出取消的国歌。 (见<input category=“button”....../>将更为合适。)

Answer 4

.cancel is a class selector. Specifically it is looking for input elements with the type attribute set to submit, but don t have the cancel class. It also looks for elements with the tagName button.

You can "designate a button as cancel" like this:

<input type= submit  class= cancel  />

Answer 5

basically it is selector which says give me submit buttons without cancel class and buttons and apply click handler. try to look up the following selectors

tag .class :not
