编辑:代码没问题,问题是
select
select
,无法使用动态角度元素,请使用类browser-default而不是input-field并且不要使用jquery进行无效化。
您好我试图在{
"records":[
{
"numero":"312312"
},
{
"numero":"31221111"
},
{
"numero":"311241"
},
{
"numero":"112441"
},
{
"numero":"11312"
},
{
"numero":"131"
}
]
}
标记中显示带有角度的数据
我读了很多,但我无法解决这个问题。正如你可以看到测试代码的工作,但功能没有。需要帮忙。感谢。
这是PHP端点返回的JSON:
app.controller('chequeoCtrl', function($scope, $http) {
//with this function do not work
$scope.leerNumero = function() {
$http.get("objetos/autoelevador/leer_numero.php").success(function(response) {
$scope.data = response.records;
console.log($scope.data);
});
};
$scope.leerNumero();
// with this array works, just for test!!
/*$scope.names = [{"name":"pepe"},{"name":"pepe2"}];
console.log($scope.nombres); */
})
控制器:
select
我的<select ng-model="autoelev" ng-options="item.numero as item.numero for item in data">
<option value="" disabled selected>Seleccionar autoelevador</option>
</select>
代码:
var startX = 501;
var finalX = 320;
var multiply = .01;
var res = finalX - startX;
var extract = multiply * res;
var toEval;
if (res > 0) {
toEval = "<=";
} else {
toEval = ">=";
}
console.log("extract= " + extract + "");
while (eval(startX + toEval + finalX)) {
startX += (-1.81);
console.log(startX + " " + extract);
}

尝试以下代码,Demo here:

<body ng-controller="MainCtrl">
<select ng-options="item.numero for item in data" ng-model="chosen">
<option value="" disabled selected>Seleccionar autoelevador</option>
</select>
</body>
<强>控制器:强>
angular.module('app', [])
.controller('MainCtrl', function($scope, $http) {
$http.get('data.json')
.then(function(res) {
$scope.data = res.data.records;
console.log($scope.data);
});
})
在控制器中执行$scope.data = response.data.records
并确保其中包含一系列选项。
console.log($scope.data)
应如下打印:
[{"numero":"312312"},{"numero":"31221111"},{"numero":"311241"},{"numero":"112441"},{"numero":"11312"},{"numero":"131"}

根据$ http文档,您的响应对象有一个data属性,用于存储您的数据(https://docs.angularjs.org/api/ng/service/ $ http)
所以你应该使用
post 'sites_search_results' => sites_search_results#index
也不推荐使用成功函数。请使用
$scope.data = response.data.records;

您可以使用angularjs从数据库中选择数据。
// Application module
var App = angular.module('myApp',[]);
App.controller("DbController",['$scope','$http', function($scope,$http){
// Function to get details from the database
getInfo();
function getInfo(){
// Sending request to sample.php files
$http.post('databaseFiles/sample.php').success(function(data){
// Stored the returned data into scope
$scope.details = data;
});
}
<强> Details.php。强>
<?php
// Including database connections
require_once 'database_connections.php';
// mysqli query to fetch all data from database
$query = " ";//write your select query
$result = mysqli_query($con, $query);
$arr = array();
if(mysqli_num_rows($result) != 0) {
while($row = mysqli_fetch_assoc($result)) {
$arr[] = $row;
}
}
// Return json array containing data from the databasecon
echo $json_info = json_encode($arr);
?>
