我试图找到最适合使用Checkbox的选项,您可以在其中进行多项选择,并且当您将表单打开到编辑模式时,所有选择的值都显示选中标记
任何建议最欢迎
*我正在尝试提交多选复选框,但是我可以对其进行编辑,如果有人有任何想法请帮助我,它不会显示选中的复选框*
或者您可以通过formcontrolName的“多选”复选框帮助我,在那里保存并查看表单的值
HTML代码
<tr *ngFor="let roleObj of roleNameList" class="outer-border">
<td id="tag" class="text-center">
<mat-checkbox (change)="selectRoleID($event)" ng-selected="true" [(ngModel)]="checked" [id]=roleObj.roleId value="{{roleObj.roleId}}"></mat-checkbox>
<td id="tag">{{roleObj.roleName}}</td>
<td id="tag">For {{roleObj.roleName}} Users</td>
</tr>
在这里,我从复选框中获得价值,可以提交 打字稿代码
onSubmitMethod() {
let roleObj: any = {};
roleObj['userId'] = this.getUserId;
roleObj['roleId'] = this.selectedRoleNameList;
this.newService.setUserRoleWrapperDetails(roleObj)
.subscribe(data => {
if (data.id == null) {
alert("Role Not Assign");
}
else {
alert("Your Data has been updated successfully!!! ");
this.newService.pageRefresh();
}
});
}
selectRoleID(event) {
console.log(event);
console.log(event.checked);
console.log(event.source);
console.log(event.source.value);
let checkBoxevent = event.checked;
let selectedValue = event.source.value;
if (checkBoxevent) {
this.selectedRoleNameList.push(selectedValue);
}
else {
const index: number = this.selectedRoleNameList.indexOf(selectedValue);
if (index !== -1) {
this.selectedRoleNameList.splice(index, 1);
}
}
}
