为什么重定向文件下载会触发有角的ui路由器，否则会生效？

Question

My routing scheme has an otherwise rule:

$urlRouterProvider.otherwise("/a");

I have this function:

function getCSV(TableName) {
            window.location = API_ENDPOINT + '/EditValidationXREF/GetCSV?TableName=' + TableName;
        }

The issue is that when I fire the function getCSV , i may be at state z but I automatically get rerouted to a (which I assume is the otherwise rule in action). Why does this happen and how can I avoid this (ie stay at state z after the download).

Answer 1

Figured this out. The link that was executing getCSV looked like:

<a href="#" ng-click="vm.getCSV('TableName')">Interchanges</a>

which obviously redirected the browser to the page without the route (and so triggered the otherwise rule as intended).

Solution:

<a href="javascript:void(0)" ng-click="vm.getCSV('TableName')">Interchanges</a>

Answer 2

The function

function getCSV(TableName) {
            window.location = API_ENDPOINT + '/EditValidationXREF/GetCSV?TableName=' + TableName;
        }

is actually changing the location of the window to something, something that the application is unable to identify to, or resolve. Thats the reason, its navigating to the URL associated to otherwise. One of the alternative methods to simply download the file is to change the above function to:

function getCSV(TableName) {
            window.open(API_ENDPOINT + '/EditValidationXREF/GetCSV?TableName=' + TableName, _blank);
        }

This would download the file, without the navigation.
