jQuery嵌套函數不起作用

[英]Jquery Nested Functions Not Working

我的代碼的目的是解決由三個方程組成的系統。 我想發生的是隱藏“ p”選擇器和“ answer”類。 當“ h1”選擇器上存在“ click”事件時,我希望它顯示下一個元素。 但是,在“按鈕”類上發生單擊事件后,我希望“矩陣”類向上滑動,然后希望“答案”類向下滑動,從而在隱藏或“ slideUp”時顯示HTML表單結果的答案原始形式和標題。

最初,“ my_code.js”文件隱藏“ p”元素並在單擊h1選擇器之前對其進行滑動切換沒有問題,但是一旦添加了其他代碼,一切就完成了。

我的jquery腳本中發生了什么? 我是否錯誤地定位了祖先元素?

JQUERY文件

$(document).ready(function() {
    $("p, .answer").hide();


    $("h1").click(function() { 
        $(this).next().slideToggle(300);
    });

    $(".button")click(function() { //after form submission
        $(".matrix").slideUp(300, function(){ //hiding the matrix form
            $(".answer").slideDown(300); //and display the answer
        });
    });

});

您的Jquery代碼行#9:

$(".button")click(function() {

您缺少“。” 在選擇器之后:

$(".button").click(function() {

我看到許多問題:

  • 您錯過了$(".button")click的句$(".button")click ,應為$(".button").click
  • 小提琴有一個結束腳本標記(fyi在那里不需要),但是您沒有document.ready函數的結束括號。
  • 您有一個內聯onClick處理程序,該處理程序調用了document.ready函數內部定義的函數。 這將對html元素不可見。 您已經在使用jQuery,因此只需使用點擊處理程序
  • 對於計算器部分,您具有相互包裝的多個函數,這是不必要的,並且會導致一些示波器問題。 您還可以將本機js與jquery混合使用,並在$選擇器可用時使用document.getElement*類型代碼

小提琴讓您入門

您的第二個<h1> (新的)用</h2>關閉。 (可能不是主要問題。)
