我有一个表,在其列中我想要用户点击此列内的按钮弹出窗口出现有复选框,用户选中复选框后它将在同一列中显示为有按钮的输出以及将所选复选框和用户名的这些值发布到数据库(PHP)。我是初学者,我希望有人帮助我。
help.html代码:
<html>
<head>
<SCRIPT LANGUAGE="JavaScript">
myPopup = '';
function openPopup(url) {
myPopup = window.open(url,'popupWindow','width=640,height=480');
if (!myPopup.opener)
myPopup.opener = self;
}
</SCRIPT>
</script>
</head>
<body>
<table border="1">
<tr>
<th> user name </th>
<th>product selected</th>
</tr>
<tr>
<td> <input type="text"/></td>
<td> <button onclick="openPopup('f.html')">select</button></td>
</body>
</html>
这是我的f.html代码:
<HTML>
<HEAD>
</HEAD>
<BODY>
<FORM NAME="popupForm">
<INPUT TYPE="checkbox" >Cell phone</br>
<INPUT TYPE="checkbox" >TV</br>
<INPUT TYPE="checkbox" >Book</br>
<INPUT TYPE="BUTTON" VALUE="Submit">
</FORM>
</BODY>

使用AngularJS,您可以这样做:
array.indexOf(item) !== -1
来完成,如果项目在数组中,则返回true。你也可以在没有AngularJS的情况下完成它,但我认为你必须做更多的代码才能获得这种行为。
(我对javascript和AngularJS也很陌生,所以代码并不完美,但它确实有效。)
可能有些事情可以改进,例如使用服务来执行ajax请求。
脚本中有一个错误: 取消点击无法按预期工作。取消点击即可更改数据。 您可以通过使用范围数据的副本来解决此问题,或者如果单击取消则还原原始数据。
请在下面找到演示文稿(因为看起来bootstrap.ui使用的是不允许使用的Cookie),所以请点击jsFiddle。在jsFiddle检查它。它有效。
var app = angular.module('myApp', ['ui.bootstrap']);
app.controller('mainController', function($scope, $modal, $log) {
$scope.products = ['coffee', 'beer', 'wine', 'tea', 'milk'];
// userData will be later from server with $http.get('/phpscript').success(...)
// just dummy userData here because no backend available
$scope.userData = [
{
name: 'John Doe',
selectedProducts: [
'coffee',
'beer',
'wine']
},
{
name: 'Jane Doe',
selectedProducts: [
'coffee',
'tea']
}
];
$scope.changeProducts = function(userData) {
//$scope.items = ['item1', 'item2', 'item3'];
var modalInstance = $modal.open({
templateUrl: 'myModalContent.html',
controller: 'ModalInstanceCtrl',
//size: size,
resolve: {
user: function() {
return userData;
},
selectedProducts: function() {
return userData.selectedProducts;
},
products: function () {
//console.log($scope.selectedProducts);
return $scope.products; // get all available products
}
}
});
modalInstance.result.then(function (selectedItems) {
//products = selectedItems;
}, function () {
$log.info('Modal dismissed at: ' + new Date());
});
};
});
app.controller('ModalInstanceCtrl', function ($scope, $http, $modalInstance, products, selectedProducts, user) {
//console.log('user', user);
$scope.products = products;
$scope.selected = selectedProducts;
$scope.chkChange = function(item) {
console.log(item);
var index = $scope.selected.indexOf(item);
if (index > -1) {
$scope.selected.splice(index, 1);
}
else {
// not selected --> we have to add it
$scope.selected.push(item);
}
console.log($scope.selected);
};
//console.log(selectedProducts);
$scope.ok = function () {
// prepare everything for sending to sever
// --> probably check here if the data have changed or not (not implemented yet)
console.log('new selection', $scope.selected);
var data = $.param({
json: JSON.stringify({
user: user.name,
products: $scope.selected
})
});
$http.post('/echo/json/', data)
.success(function(data, status) {
console.log('posted the following data:', data);
});
$modalInstance.close();//); $scope.selected.item);
};
$scope.cancel = function () {
$modalInstance.dismiss('cancel');
};
});
//custom filter to display the selected products.
app.filter('array', function() {
return function(input) {
//console.log(input);
return input.join(', ');
};
});
