<div runat="server" class="export">请不要直接打开此页面</div> <button class="Btn" onclick="javascript: location.href = 'Default2.aspx'">返回</button> 上面是源码 <div runat="server" class="export">请不要直接打开此页面</div> <div class="clear" ></div> <button class="Btn" onclick="javascript: location.href = 'Default2.aspx'">返回</button> 还需要在 CSS中加入.clear{ clear:both} ，这样随后跟上的BUTTON标签就会到下一行了

React(dispatch与参数传递)

由 匿名 (未验证) 提交于 2019-12-02 23:36:01
只允许两种形式 onClick={fn}; 或 onClick={()=>{fn()}}; //onClick={()=>{fn(id)}}; 不能这么写 onClick={fn(id)}; 此外 onClick={()=>{fn()}}; 等效于 onClick={fn}; 第1种写法(由父组件dispatch,参数不流入TodoItem) TodoList todos.map((item) => ( <TodoItem ...... onToggle={() => onToggleTodo(item.id)} onRemove={() => onRemoveTodo(item.id)} /> )) ...... const mapDispatchToProps = (dispatch) => { return { onToggleTodo: (id) => { dispatch(toggleTodo(id)); }, onRemoveTodo: (id) => { dispatch(removeTodo(id)); } }; }; TodoItem <input ... onClick={() => {onToggle()}} /> <button ... onClick={()=>{onRemove()}}>×</button> //这么写很蠢 或 <input ...

由 匿名 (未验证) 提交于 2019-12-02 23:34:01
　　业务需求：不同角色有不同的权限，我们根据角色加载页面时展示不同的菜单。在easyUI中，菜单一般采用手风琴accordion组件进行展示，一级菜单下可以加载二级菜单，效果如下： 　　普通用户看到的菜： 　　管理员看到的菜单： 　　点击二级菜单后将在右边添加一个tab页，支持多个tab页同时展示： 　　接下来看实现： 　　html我们把各种角色都需要展示的菜单列出来，比如：订单查询跟发票生成 <div data-options="region:'west',title:'菜单',split:true,iconCls:'icon-table'" style="width:180px;"> <div id="menus" class="easyui-accordion" data-options="fit:true,border:false,selected:false"> <div data-options="title:'订单查询',iconCls:'icon-page'" style="padding:8px;"> <ul class="easyui-tree" data-options="onBeforeSelect:function(node){return false;}"> <li><a onclick="tab_add('订单查询','/orders.html')"

Js的引入 由于单纯的html和css是没有动态的效果的，所以为了增加动画效果，当让js也可以做一些验证的工作。 实例 我就将我练习的简单例子列一下，方便日后查看。 test1: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <p id="pid"> hello world </p> <script> //js的注释和java的注释是一样的 document.write("666"+"<br/>"); //var是宽松数据类型 var str="hello String"; var i = 10; var j = 10; //var arr = new Array(); var arr = [1,2,3,"string"]; arr[0]=1; document.write("数组长度："+arr.length+"<br>"); document.write("第四个数组元素是："+arr[3]+"<br>"); document.write(i+j); //弹出一个对话框(点击确定之后会显示下一个对话框) alert(arr[3]); function sum(a,b) { alert(a+b); var c = 10; } //var c= sum(10,

Play audio and restart it onclick

由 房东的猫 提交于 2019-12-02 23:08:57
I'm looking to restart an audio file in a HTML5 audio player. I have defined a audio file and a play button. <audio id="audio1" src="01.wav"></audio> <button onClick="play()">Play</button> When I click the play button the audio file starts playing, but when I click the button again the audio file doesn't stop and will not play again until it reaches the end of the file. function play() { document.getElementById('audio1').play(); } Is there a method that would allow me to restart the audio file when I click the button using onclick rather than waiting for the song to stop? To just restart the

how to use visible and invisible for a button in android

由 左心房为你撑大大i 提交于 2019-12-02 23:05:54
I want to make a button invisible, when i click another button then the invisible button will become visible and then perform onClick() actions on the visible button. What onClick() actions I can use on the visible button. I used this method shown below: donebutton = (Button) findViewById(R.id.done); donebutton.setOnClickListener(this); donebutton.setVisibility(View.INVISIBLE); @Override public void onClick(View v) { // TODO Auto-generated method stub if(v.equals(remove)) { donebutton.setVisibility(View.VISIBLE); } if(v.equals(donebutton)) { Intent i=new Intent(One.this,Second.class);

Android - delayed clicks in ListView

由 余生颓废 提交于 2019-12-02 22:39:33
I have the following structure in my app: FragmentActivity with ViewPager holding multiple fragments managed by FragmentStatePagerAdapter using compativility pack with Android 2.1 Each fragment contains ListView . Each element in the ListView has a LinearLayout with two TextViews and a Button . The LinearLayout and the button have onClickListeners (separate). Clicking on the LinearLayout starts another Activity . I noticed that the clicks behavior is very inconsistent: sometimes action is executed immediately but very often it is delayed and sometimes it's just ignored no matter how many times

Java scripts not working in html email template

As a html(Web Page), it works perfectly good but then when i send a mail and try with the click of a button in my mail, the onclick not raised the jscript and hence no action has happened and it was actually disabled . I checked
