我试图通过单击按钮自动聚焦在输入元素上。请参阅打字稿

@ViewChild('envFilter') envFilter: ElementRef;
onFilterSelect() {
    this.envFilter.nativeElement.focus();
}

在 HTML 方面，我有以下内容。

<div [ngClass]="isFilterVisible ? 'item item1' : 'item item1 hide'">
     <div [@filterAnimation]="isFilterVisible" class="filterWrapper">
          <input type="text" class="envFilter" [(ngModel)]="envFilterValue" (keyup)="envFilterChanged(envFilterValue)" #envFilter />
            <!-- {{ envFilter.focus() }} -->
      </div>
</div>

使用时{{ envFilter.focus() }}我能够专注于该字段，但无法专注于任何其他输入框

这里遗漏了一小段 HTML

<div class="pull-right  filter-down filter-down-div item item2">
     <i *ngIf=" envs.length !=0" role="button" (click)="onFilterSelect(envFilter)" class="filter-icon fas fa-search"
            [ngClass]="{'active': isFilterVisible ,'disabled':!isFilterVisible}" role="button"></i>
</div>

该段基本上是一个搜索按钮，单击时会调用前面的 onFilterSelect() 函数

我的代码有问题吗？为什么自动对焦不起作用

我尝试根据java脑中的教程创建Message源,我在尝试将选项设置为有多个消息属性文件时遇到了问题,产生了错误,错误在下面给出

我有一个表格，其中最后一列中有一个名为 issue 的按钮。在每一行中，当我单击按钮时，我希望它调用一个从服务器获取特定值的 ajax 函数。来自服务器的值将根据选择的行而有所不同。我目前的代码如下

var $dntb = $("#dntb");
$dntb.on("focusin", function() {
        var i //have to get the row where the button is clicked 
        $("#iss" + i).click(function(event) {
        var sditmId = $("#sditm").val();
        var sdhedId = $("#sdhed").val();
        $.get('getstock', {
               sditmId: sditmId,
               sdhedId: sdhedId
        }, function(response) {
        $("#stk").val(response);
        });
        });
});

请告诉我如何在上面的代码中找到'i'的值，如果这是错误的请告诉我正确的方法

下表给出

<table class="table table-bordered table-striped table-hover" id="dntb">
