我是angularjs的新手,想要点击复选框时创建模型数组,下面是我的代码..
$scope.selectedAlbumSongs = [{
'name': 'song1',
'url': 'http://test/song1.mp3'
}, {
'name': 'song2',
'url': 'http://test/song2.mp3'
}, {
'name': 'song3',
'url': 'http://test/song3.mp3'
}];
$scope.playList = {};
HTML:
<fieldset data-role="controlgroup">
<legend>Select songs to play</legend>
<label ng-repeat="song in selectedAlbumSongs">
<input type="checkbox" name="{{song.url}}" id="{{song.name}}" ng-model="playList[song.url]">
<label for="{{song.name}}">{{song.name}}</label>
</label>
</fieldset>
当我单击复选框时,上面的代码更新了playList,如下所示
{
"http://test/test1.mp3": true,
"http://test/test2.mp32": true,
"http://test/test3.mp3": false
}
但我想以下面的格式创建ng-model,并在取消选中该复选框时删除该对象(例如,如果取消选中song3,则从该数组中删除song3对象).你能告诉我怎么写这个逻辑吗？
预期:
[{
name: "song1",
url: "http://test/song1.mp3"
}, {
name: "song2",
url: "http://test/song2.mp3"
}]
这是我的javascript对象,我想添加选项到下拉列表？我希望属性名称作为值和属性值在每个选项中作为文本？
{ "": "", "CSharp40": "C# 4.0", ".NET": ".NET", "JQuery": "JQuery", "Javascript": "Javascript" }
输出如下
<select id="courses">
<option value=""></option>
<option value="CSharp40">C# 4.0</option>
<option value=".NET">.NET</option>
<option value="JQuery">JQuery</option>
<option value="Javascript">Javascript</option>
</select>
你能告诉我如何为此编写Mustache模板吗？提前致谢
this is my log4net configuration, the rollover log file is created wrong extension. The first file created with name of log_debug.txt and the rollover file created with log_debug.txt.1. but ideally it should be log_debug.1.txt.
I used preserveLogFileNameExtension value to be true, but it seems not working. Can you please check and let me know if anything wrong?
<appender name="DebugRollingFileAppender" type="log4net.Appender.RollingFileAppender,log4net">
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="DEBUG" />
<levelMax value="DEBUG" />
</filter>
<file value=".\logs\log_debug.txt" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="20" …在下面的html设计中,我想将文本溢出应用于省略号,用于媒体播放和备注标签,并希望第一行播放的媒体(第一个大行)和备注(第二个bing行)将继续下一个线.播放和停止以及媒体播放和备注都应该属于同一行.你能帮帮我吗？

</li> …我收到错误“无法访问请求的页面，因为该页面的相关配置数据无效。” 当我在 WCF 应用程序的 web.config 中使用重写元素时。
<rewrite>
<rules>
<rule name="Rewrite Index">
<match url="myApplicaiton/Healthcheck.aspx" />
<action type="Redirect" url="HealthCheck.aspx" />
</rule>

如果请求 url 包含“myApplication” http://localhost/myApplication/HealthCheck.aspx我想要重定向（服务器重定向）。您能否告诉我上述配置是否有任何问题，并让我知道是否有其他方法对 WCF 应用程序 web.config 中的静态文件进行重定向
我用setTimeout函数包装了长时间运行的逻辑(longLoop),但是在长时间运行执行之前,UI仍然没有响应.它不允许单击其他UI按钮.请查看下面的示例,如果您看到任何问题,请告诉我.
function longLoop () {
var startLogTime, endLogTime;
startLogTime = new Date().getTime();
console.log("loop begin");
for (var i = 0; i <= 500000000; i++) {
var j = 10;
}
endLogTime = new Date().getTime();
console.log("loop execution takes " + (endLogTime - startLogTime) + " milliseconds");
}
$(document).ready(function () {
$("#btnButton").bind("click", function () {
setTimeout(longLoop, 15);
});
$("#anotherButton").bind("click", function () {
console.log("another operation clicked");
});
});
<input type="button" id="btnButton" value="Start Long Operation" />
<input type ="button" id="anotherButton" value= "Another operation" />
谢谢
