如何从Web服务器URL路径检索图像到angularJS [英] How to retrieve image from a web server url path to angularJS
问题描述
我正在尝试从Web服务器(端口9100)上检索图像,以显示在我的angularJS页面上.
I am trying to retrieve images from my web server (on port 9100) to display on my angularJS page.
我想在表格的特定单元格中显示图像.
I wanted to display the image in the particular cell in my table.
当我单击查看"按钮时,"04080b363fb9d8fe825c7c664bb7a38d.png"表上将显示"04080b363fb9d8fe825c7c664bb7a38d.png"图像.
Example like: "04080b363fb9d8fe825c7c664bb7a38d.png" image will be shown on the "04080b363fb9d8fe825c7c664bb7a38d.png" table when I click on the "view" button.

<div ng-controller="Hello">
<h3>Search:</h3><br>

<table style="width:55%">

<tr>
<th>CamID</th>
<th>Timestamp</th>
<th>View Image</th>

<tbody>
<tr ng-repeat="record in records | filter:searchBox | orderBy:'+timestamp'">
<td>{{record.cameraid}}</td>
<td>{{record.timestamp}}</td>
<td>{{record.filename}}</td>
<td><button ng-click="toggleCustom()" onclick="myFunction()">View</button></td>
</tr>

</table>
<span id="myDIV" ng-hide="custom">
<img ng-src="" width="300" height="300">

<span ng-show="custom"></span>
</div>
<script>
function myFunction() {
document.getElementById("myDIV").style.position = "absolute";
}
</script>
</body>
</html>
我的js文件:
var camListApp = angular.module('camListApp', []);
camListApp.filter('unique', function() {
return function(input, key) {
var unique = {};
var uniqueList = [];
for(var i = 0; i < input.length; i++){
if(typeof unique[input[i][key]] == "undefined"){
unique[input[i][key]] = "";
uniqueList.push(input[i]);
}
}
return uniqueList;
};
});
camListApp.controller('Hello', ['$scope', '$http', function($scope, $http){
$scope.custom = true;
$scope.toggleCustom = function() {
$scope.custom = ! $scope.custom;
};
$http.get('http://localhost:8081/camera/list').then(function(response) {
console.log(response);
$scope.records= response.data;
});
}]);
有人可以帮我吗?
推荐答案
为了获得预期的结果,我使用了很少的示例图像,并假设来自后端的数据将采用以下格式
To achieve the expected result, i have used few sample images with the assumption that the data from the backend will be in the format as below
$scope.records=[{"id":23,"cameraid":"001","timestamp":"2016/06/15 17:27","filename":"http://www.w3schools.com/css/img_fjords.jpg"},
{"id":24,"cameraid":"002","timestamp":"2016/06/15 17:28","filename":"
{"id":24,"cameraid":"002","timestamp":"2016/06/15 17:28","filename":"http://www.w3schools.com/css/img_forest.jpg"}, {"id":25,"cameraid":"003","timestamp":"2016/06/15 17:28","filename":"http://www.w3schools.com/css/img_lights.jpg"}, {"id":26,"cameraid":"003","timestamp":"2016/06/15 17:28","filename":"http://www.w3schools.com/css/img_mountains.jpg"}]
