我有以下HTML代码
<ul ng-repeat="friend in friends | filter: { age: '2' } | orderBy: 'name' ">
<li>{{friend.name}}</li>
</ul>
这是我的$ scope变量
$scope.friends = [
{ name: "Peter", age: 2 },
{ name: "Pablo", age: 55 },
{ name: "Linda", age: 20 },
{ name: "Marta", age: 37 },
{ name: "Othello", age: 20 },
{ name: "Markus", age: 32 }
];
它回来了
Linda
Markus
Othello
Peter
如何在ng过滤器中进行比较,以及如何让我的朋友只有2岁
Peter
我有一个文本框,并仅使用jquery应用允许使用空格的字母.它在chrome中工作但是在firefox中,退格键不起作用.
<input type="text" placeholder="" id="id1">
$(function(){
$('#id1').keypress(function (event) {
if ((event.which >= 65 && event.which < 91) || (event.which > 96 && event.which < 123) || event.which === 32 || event.which===0) {
return true;
}
else {
event.preventDefault();
}
})});
这是Plnkr
我如何解析以下字符串
var a = JSON.parse('[' + '{"NoteName":"it's my life","UserId":"100","NoteActive":true,"UserEmail":"admin@dev.xrc.com","CreatedDate":"8/13/2012 1:47:35 PM"}' + ']');
我有以下HTML
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Example - example-ngModel-getter-setter-production</title>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular.min.js"></script>
<script src="app.js"></script>
</head>
<body ng-app="getterSetterExample">
<div ng-controller="ExampleController">
<form name="userForm">
<label ng-repeat="id in ids">
<input type="checkbox"
value="{{id.id}}"
ng-checked="id.id == csv"> {{id.id}}
</label>
</form>
</div>
</body>
</html>
控制器是
(function(angular) {
'use strict';
angular.module('getterSetterExample', []).controller('ExampleController', ['$scope', function($scope) {
$scope.csv = '5,6,76,78';
$scope.ids = [
{id:5},
{id:64},
{id:456},
{id:47},
{id:767},
{id:78},
{id:55},
{id:98}
];
}]);
})(window.angular);
我想在csv中找到id时检查复选框.例如,id 5和78在csv中,因此最初应选择这两个值复选框
我有一个名为'User'的类和一个属性'Name'
public class User
{
[Required]
public string Name { get; set; }
}
而api控制器的方法是
public IHttpActionResult PostUser()
{
User u = new User();
u.Name = null;
if (!ModelState.IsValid)
return BadRequest(ModelState);
return Ok(u);
}
如何手动验证User对象,以便ModelState.IsValid向我返回false？
我有具有滚动功能的引导模式。我想在滚动点击模式底部（不是页面底部）时从 AJAX 调用加载数据。我正在使用这个 jQuery 代码，但它不适用于这个引导模式。
$(window).scroll(function() {
if($(window).scrollTop() == $(document).height() - $(window).height()) {
// ajax call get data from server and append to the div
}
});
这是我的模型

<div class="modal-dialog" style="overflow-y: scroll; max-height:85%; margin-top: 50px; margin-bottom:50px;">
