get all elements with onclick in them?

阅读更多关于 get all elements with onclick in them?

问题 I am looking for a way to list all elements that have onclick event on a page. 回答1: Edited to answer further questions... I'm not sure exactly what you're asking, but I suspect you're looking for a way to see if there has been code attached to an element's onclick event? If so, try this: var allElements = document.getElementsByTagName('*'); for ( var i = 0; i<allElements.length; i++ ) { if ( allElements[i].className !== 'theClassNameYoureLookingFor' ) { continue; } if ( typeof allElements[i]

Activity生命周期

阅读更多关于 Activity生命周期

本篇博客是个备忘录，是我工作中遇到的生命周期方法调用的一些总结。讲Activity的声明周期之前，先讲讲Actiivty的启动模式。其与Activity的声明周期和启动流程息息相关。四大启动模式 1、Standard 模式默认启动模式，每次启动一个activity都会重新创建一个新的实例，放入栈顶。因此启动时 onCreate、onStart、onResume 方法都会被调用。 // 伪代码 // 标准模式：走onCreate ---> onStart ---> onResume if(isStandard) { // 创建新的Activity实例 createNewActivity(); } 2、singleTop模式 singleTop模式，又叫栈顶复用模式，当前栈中已有该activity实例并且该实例位于栈顶，复用该activity，调用onNewIntent，onResume方法；其他都是重新创建实例。走 onCreate、onStart、onResume 流程。 // 伪代码 if(isStackTop) { // 已存在实例并且在任务栈栈顶，复用当前实例，走 onNewIntent ---> onResume reuseExistActivity(); } else { // 创建新的Activity实例，走onCreate ---> onStart --->

Uncaught ReferenceError: onclick is not defined

错误显示解决方法 1.首先全局声明一个全局函数 var xka; 2.修改函数方法改为 xka = function (){ alert("hhhh"); } 然后你就会发现调用成功出现原因(个人认为) 这个出现是因为作用域的问题，在一个作用于里面调不到另一个作用域的函数，在我第一个调用xka()这个方法时，它要求这个函数立马执行，可以成功调用所以就是局部变量；但是标签的onclick是要求全局函数，xka = function(){}的写法会把xka函数作为全局作用域函数，相当于windows对象作为他的作用域，所以可以被调用到。如果发现博文有问题，欢迎各位老鸟指导一波来源： CSDN 作者： Hello Bug 链接： https://blog.csdn.net/AdminPwd/article/details/103887748

addEventListener与onclick

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> addEventListener 和 onclick 什么区别？ var h = document.getElementById("a"); h.onclick = dothing1; h.addEventListener("click", dothing2); 上面的代码一起驻留在单独的.js文件中，并且它们都可以正常工作。 #1楼 JavasSript中 'this' 关键字引用的上下文不同。看下面的代码： <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> </head> <body> <input id="btnSubmit" type="button" value="Submit" /> <script> function disable() { this.disabled = true; } var btnSubmit = document.getElementById('btnSubmit'); btnSubmit.onclick = disable(); //btnSubmit.addEventListener('click', disable, false); </script>

adding and remove classes on click events

阅读更多关于 adding and remove classes on click events

问题 I am working on a click event, which intially is pretty standard. on.click: Remove the active class from all list items, then add active to the clicked list item. ie var li = $('.child-item'); li.click(function(){ li.removeClass('active'); li.addClass('active'); }); Works as expected. However, I also need a condition that if the active class is clicked again, it will remove the active class from the clicked item. I tried this: $('.child-item').toggle(function(e){ $('.child-item').removeClass(
