在我的index.html
中,我有一个button
我以前用来提交数据然后发送到我的数据库。但是,我最近更改了布局以包含依赖CSS
的标签。
现在,相同的button
仅刷新页面,并且不对数据执行任何操作。我尝试更改button
类型,form
,添加evt.preventDefault()
等等无济于事。
以下是我form
的{{1}},为了方便起见,我减少了一些标签的重复。
index.html
这是我的控制器表格:
<!DOCTYPE html>
<html ng-app>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width,initial-scale=1.0,minimum-scale=1.0">
<link rel="stylesheet" href="//cdnjs.cloudflare.com/ajax/libs/font-awesome/3.1.0/css/font-awesome.min.css" />
<script src ="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.9/angular.min.js"></script>
<% include header %>
<% include navbar %>
<p>
extra space
<body>
<!-- tabs -->
<div class="pcss3t pcss3t-effect-scale pcss3t-theme-1">
<input type="radio" name="pcss3t" checked id="tab1"class="tab-content-first">
<label for="tab1"><i class="icon-calendar"></i>Client</label>
<!-- tab contents -->
<li class="tab-content tab-content-3 typography">
<!-- /container -->
<script type="text/javascript">
$(document).ready(function() {
$('#home').addClass("active");
});
</script>
<h1>Clients</h1>
<div class="container">
<div ng-controller="ClientCtrl">
<span>{{remaining()}} of {{clients.length}} remaining</span> [ <a
href="" ng-click="archive()">archive</a> ]
<ul class="unstyled">
<li ng-repeat="client in clients"><input type="checkbox"
ng-model="client.done"> <span class="done-{{client.done}}">{{client.text}}
</span>
</li>
</ul>
<form ng-submit="addClient()">
<div class="col-lg-6">
<div class="input-group input-group-lg">
<input class="form-control" type="text" ng-model="clientText"
size="30" placeholder="add new client here"> <spanclass="input-group-btn">
<button class="btn btn-primary btn-lg" type="button">Add</button>
</span>
</div>
</div>
</form>
</div>
</div>
</div>
单击按钮时在命令提示符下收到的消息结果为:
function ClientCtrl($scope, $http) {
$scope.clients = [];
$http.get('/client').success(function(data, status, headers, config) {
$scope.clients = data;
if (data == "") {
$scope.clients = [];
}
}).error(function(data, status, headers, config) {
console.log("Ops: could not get any data");
});
}
}
$scope.addClient = function() {
$http.post('/client', {
text : $scope.clientText,
done : false,
}).success(function(data, status, headers, config) {
$scope.clients.push({
text : $scope.clientText,
done : false
});
$scope.clientText = '';
}).error(function(data, status, headers, config) {
console.log("Ops: " + data);
});
};
$scope.remaining = function() {
var count = 0;
angular.forEach($scope.clients, function(client) {
count += client.done ? 0 : 1;
});
return count;
};
$scope.archive = function() {
var oldClients = $scope.clients;
$scope.clients = [];
angular.forEach(oldClients, function(client) {
if (!client.done)
$scope.clients.push(client);
});
};
}

表单提交处理程序(ng-submit
或onsubmit
)旨在将数据提交到表单action
属性中提供的路径。没有属性,数据将提交到当前地址,页面将刷新。
要避免默认行为,您从ng-submit调用的方法必须返回false。这样可以防止重定向发生,并允许保留范围更改。
$scope.addClient = function() {
$http.post('/client', {
text : $scope.clientText,
done : false,
}).success(function(data, status, headers, config) {
$scope.clients.push({
text : $scope.clientText,
done : false
});
$scope.clientText = '';
}).error(function(data, status, headers, config) {
console.log("Ops: " + data);
});
return false;
};
n.b。根据您的描述,由于在页面刷新后通过在/ client端点上调用GET不更新数据,因此可能存在一些关于持久性或数据检索的问题。您的实现应该使用post()调用存储数据,然后在页面重新加载时使用get()调用检索它。
