Question

我有两个选择，其中第二个依赖于第一个。我想填充他们两个。这是我的选择：

quetzalcoatl@LAP049 MINGW32 /c/w/-path-redacted- (develop)
$ git remote add asdf "KJH&*^^IGJH*"

quetzalcoatl@LAP049 MINGW32 /c/w/-path-redacted- (develop)
$ git remote -v
asdf    KJH&*^^IGJH* (fetch)
asdf    KJH&*^^IGJH* (push)
--other urls redacted--

quetzalcoatl@LAP049 MINGW32 /c/w/-path-redacted- (develop)
$ cat .git/config
[core]
    repositoryformatversion = 0
    filemode = false
    bare = false
    logallrefupdates = true
    symlinks = false
    ignorecase = true
---other sections redacted---
[remote "asdf"]
    url = KJH&*^^IGJH*
    fetch = +refs/heads/*:refs/remotes/asdf/*

在这种情况下，只填充第一个，当我点击第一个然后填充第二个。我尝试（更改）替换为（单击）但我有同样的问题。有什么建议吗？

这是我的意思：

 <div class="z-inputs no-border">
                        <div class="z-selecticon no-border">
                            <select [ngModel]="orderTracking.destinationfromCode" (ngModelChange)="modelChanged($event)" (click)="selectItemForRequest(orderTracking);selectGroup(orderTracking.destinationfromCode);">
                                <option value=""></option>
                                <option *ngFor="let destination of groupDestinations" [ngValue]="destination.code">{{destination.displayname}}</option>    
                            </select>
                        </div>
                    </div>
                    </div>
                    <div class="ui-g-1 no-border">
                        <div class="z-inputs no-border">
                            <div class="z-selecticon no-border">
                                <select  [(ngModel)]="orderTracking.destinationtoCode">
                                    <option value=""></option>
                                    <option *ngFor="let destination of destinationsTo" [ngValue]="destination.code">{{destination.displayname}}</option>
                                </select>
                            </div>
                        </div>
                    </div>
