Adding an onclick to a submenu?

六月ゝ 毕业季﹏ 提交于 2020-01-22 14:55:06
问题 I have an onclick function for my menu but I can't figure out what the ID is for my submenu so that I can tell the submenu what to do when the user click on it. I created my submenu programmatically using the code below. So if someone could please explain to me how I know what the id is for each item of the submenu I'd greatly appreciate it. @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.mainmenu, menu); SubMenu

a页面里iframe了个b页面,我想实现在b页面里一个按钮,一按就刷新a页面,也就是父页面,不是只刷新iframe里面的b页面 哦~ 请问b页面里的<input type="button" class="btn" value=" 返 回 " onclick="history.back();">那个onclick 要怎么写呢?啊哈 答案是:parent.location.reload() ; 以下是网上的: 十一种刷新按钮的方法。很不错的,经常上网要找。哈哈。这下放这里了。 <input type=button value=刷新 onclick="history.go(0)"> <input type=button value=刷新 onclick="location.reload()"> <input type=button value=刷新 onclick="location=location"> <input type=button value=刷新 onclick="location.assign(location)"> <input type=button value=刷新 onclick="document.execCommand('Refresh')"> <input type=button value=刷新 onclick="window.navigate

本文介绍JavaScript事件相关的知识点,主要包括事件流、事件处理程序、事件对象(event)以及常见事件类型和事件委托等相关内容。 在网页开发涉及的三种基础技术( HTML CSS JavaScript )中,JavaScript主要负责处理页面的 行为 ,而所谓行为大多指的是 交互行为 。 JavaScript和HTML间的交互通过事件来实现 ,换句话来说事件其实就是页面文档或浏览器窗口中发生的特定交互,譬如页面中的按钮标签被点击我们称之为按钮的点击( click )事件,类似的还有页面加载事件、鼠标的移入移除等等。 通常,我们在开发中对事件的操作(处理)主要由两部分组成,即 事件注册 和 事件函数 。我们总是需要先通过特定的方式来给标签添加(注册)事件监听,当事件发生时事件函数将得以调用执行。本文以 能够清晰明确的把事件的传递过程、事件注册的方式、事件对象以及常见的事件类型讲解清楚 为目标。 事件流 事件流 描述的其实是事件内在的传递过程(顺序)。 我们的开发经验是,当我们给某些标签注册(绑定)了事件后,该事件被触发就会执行对应的事件处理函数。这似乎是一个顺理成章的经验,但事件到底是如何传递的呢 ?我们知道在网页中有很多的Node节点,而Node节点之间是复杂的树结构,事件在接收、传递和处理的时候,是按照 目标节点->上层节点->根节点 还是 根节点->下层节点-

Why can't I click() links in jQuery?

痞子三分冷 提交于 2020-01-21 08:31:25
问题 I came across a curiosity in jQuery: if I call .click() on a link the click event handlers are called, but the link isn't actually followed (as if it were clicked in the browser): <a id="link" href="http://www.google.com>Link</a> $("#link").click() // won't take me to Google But in plain Javascript, everything behaves as expected: document.getElementById("link").click() // *will* take me to Google This is apparently intentional behaviour - but I'm struggling to work out why click was

问题 I am trying to scrape names of all the items present on the webpage but by default only 18 are visible on the page & my code is scraping only those. You can view all items by clicking on "Show all" button but that button is in Javascript. After some research, I found that PyQt module can be used to solve this issue involving javascript buttons & I used it but I am still not able to invoke the "on click" event. Below is the referred code: import csv import urllib2 import sys import time from

onclick calling hide-div function not working

雨燕双飞 提交于 2020-01-19 04:10:35
问题 I've been fighting with this simple piece of code forever. I'm trying to use a <button> to call a simple JavaScript function to hide a <div> . HTML: <button type="button" onclick="close('wrong')">OK</button> JavaScript: function close(ID) { document.getElementById(ID).style.display="none"; } I'm sure it's something really simple, I just can't, for the life of me, find it. 回答1: Try changing the close function name to something else like closeit because it may be confusing it with the window

安卓开发记录(3)---仿滴滴做一个点击按钮,弹出侧边菜单

前言: 制作一个类似于滴滴点击左上角头像,弹出一个侧边菜单其实特别简单。而且不需要导入任何包,直接复制几行代码即可。如果您想尝试一下,请自行new一个模板叫:Navigation Drawer Activity。自行复制代码导入项目。 1.纯净版demo 一定要看清楚使用的是v4包的项目还是AndroidX的项目,因为他们所对应的xml tag不一样。请按照自己项目,修改对应tag < ! -- v4项目头尾文件 < android . support . v4 . widget .
