Question

我在调用ng-click时需要编辑数据。以下是代码：

<tr class="read" ng-repeat="data in records>
  <td>
   {{data.requestId}}
 </td>
 <td>
   {{data.status}}
 </td>
   <a height="20" class="pointer" 
   ng-click="download(data.downloadPath)" target="_self"></a>
 </td>

e.g。 - 如果data.downloadPath的值为 /opt/dummy/file.txt ，我需要删除第一个正斜杠并将路径指定为： opt / dummy / file.txt < /强>

是否可以在angularjs中进行编辑，或者是否需要编辑控制器代码：

someSrv.someFunction() .success(function(response){ $scope.records = response.data; }

Answer 1

Angular表达式仍然是常规JavaScript，所以我想你可以选择

ng-click="download(data.downloadPath.slice(1))"

或者，如果第一个/是可选的，并不总是存在，则使用正则表达式：

ng-click="download(data.downloadPath.replace(/^\//, ''))"

Answer 2

最简单的方法是使用substr方法

<a  ng-click="download(data.downloadPath.substr(1))" target="_self"></a>

这将完全删除"/"。 /dir/index.php将成为dir/index.php

Answer 3

您可以使用ng-if指令检查该值是否等于/opt/dummy/file.txt。

<tr class="read" ng-repeat="data in records>
  <td>
   {{data.requestId}}
 </td>
 <td>
   {{data.status}}
 </td>
   <div ng-if="data.downloadPath == '/opt/dummy/file.txt'">
     <a height="20" class="pointer" 
     ng-click="download(data.downloadPath.slice(1))" target="_self"></a>
   </div>
   <div ng-if="data.downloadPath != '/opt/dummy/file.txt'">
     <a height="20" class="pointer" 
     ng-click="download(data.downloadPath)" target="_self"></a>
   </div>
 </td>

Answer 4

试试这个

$scope.download = function(dataPath){
    var string = "dataPath";
    if (string.charAt(0) == "/") string = string.substr(1);
    if (string.charAt(string.length - 1) == "/") string = string.substr(0,string.length - 1);
    $scope.path = string;

}
