为此,我们创建了一个简单的注册表格,在这个表格的用户中,电子邮件输入字段在页面重新加载时自动聚焦。 <form(submit)="onSignup(form)"#form="ngForm"><mat-card><mat-form-field><!-- AutoFocus directive applied in the below input field --><inputautofocust

//Tip:记得 引入"$timeout","$parse" 这个事focus ,类似的 大家可以用于kedown keyup等等 引用:http://stackoverflow.com/questions/14833326/how-to-set-focus-on-input-field
// 宿主元素 click 事件,触发 focus() 事件 '(click)': 'focus()', // 切换宿主元素 focus 样式 '[class.focus]': 'focused' } }) export class InputControlComponent { private _focused: boolean = false; private _value: any = '';
但是,如果你想要设置选定值而不触发更改事件,可以使用ngModel的updateOn选项,并将其设置为'blur'。这样,只有在表单元素失去焦点时,才会触发数据绑定的更新。 示例代码: 代码语言:txt 复制 <input [(ngModel)]="selectedValue" [ngModelOptions]="{updateOn: 'blur'}" /> 使用ngModelChange事件:ngModelChange...

上述代码就使用dispatchFakeEvent(trigger, 'focus');语句模拟触发trigger元素的焦点事件,如果直接使用trigger.foucs();语句也是一样的。 dispatchKeyboardEvent 我在写编辑器的测试时,需要模拟ctrl+s、ctrl+z等复杂的键盘事件,dispatchFakeEvent就不太满足了,查了material design的最新代码,他们有封装了...
