如何调试角for循环

Question

我正在尝试做一个批上传多个pdfs。每个文件都以特定的格式命名。

02-2015 HIP BS32

日期/管道缩写/位置缩写。

我正在通过一个循环运行这些文件，以比较数据库中列表的缩写。然后，在将这些属性传递给之前，将这些属性分配给对象。管道表和位置表的设置完全相同。我现在面临的问题是管道问题。问题就在这里，

$scope.pip = $scope.pipeLookup[matches[1]];
$scope.loc = $scope.locationLookup[matches[2]];

locationLookup正在匹配位置缩写并将其放置在$scope.loc变量中。然而，pipeLookup不起作用。当然，它是抛出错误，因为管道属性是未定义的。我不知道我是不是刚看完什么东西。如果需要更多的信息，请告诉我

 $scope.companies = Company.query(function () { });
$scope.locations = Location.query(function () { });
$scope.pipes = Pipe.query(function () { });
$scope.selectCompany = function () {
    var id = $scope.companyId.CompanyId
    $http.get('/api/apiCompany/' + id)
        .success(function (result) {
            $scope.CompanyName = result.CompanyName
        });
};//

$scope.pipeLookup = {};
$scope.locationLookup = {};

$scope.upload = function () {
    var files = $scope.files;
    if (files && files.length) {
        for (var i = 0; i < files.length; i++) {
            var file = files[i];

            $scope.pipes.map(function (pip) {
                $scope.pipeLookup[pip['PipeAb']] = pip;
            });
            $scope.locations.map(function (loc) {
                $scope.locationLookup[loc['LocationAb']] = loc;
            });

            var matches = file.name.match(/^\d+\D\d+\s*?(\S*)\s*(\S*?)\./i);

            $scope.pip = $scope.pipeLookup[matches[1]];
            $scope.loc = $scope.locationLookup[matches[2]];

                var progressPercentage = parseInt(100.0 * evt.loaded / evt.total);
                console.log('progress: ' + progressPercentage + '% ' + evt.config.file.name);
            }).success(function (data, status, headers, config) {
                console.log('file ' + config.file.name + 'uploaded. Response: ' +
                            JSON.stringify(data));
            }).error(function (err, result) {
                console.log(err, result);
            });

        }
    }

Answer 1

您的正则表达式期望有一个点(.)字符结尾，但字符串不包含点(.)最后，它失败了。

如果我尝试您的regex ^\d+\D\d+\s*?(\S*)\s*(\S*?)\. 这里并传入02-2015 HIP BS32，它就不匹配了，因为您的regex在末尾需要一个.文本。

更新:下面是您的pipeLookup JSON的片段

"HIP ": {
"$id": "9",
"PipeId": 9,
"PipeAb": "HIP ",
"PipeName": "American Midstream High Point Pipeline",
"Documents": null

}

这里的关键是"HIP“，注意HIP之后的额外空间。这就是为什么$scope.pipeLookup[matches[1]]什么也不返回的原因。在将尾随空间存储在pipeLookup对象中之前，先删除它

Update:更仔细地看一下，如果file.name包含这个值02-2015 HIP BS32，如果您想从其中获取HIP值，可以使用以下正则表达式

/^\d+\D\d+\s*(\S*\s*)(\S*)/i
