这是我的示例代码。 请在此处找到我的工作示例代码
我需要在垫子对话框的右上角设置三角形 - Angular。
我在最后一行使用静态 css 获得右上角三角形对话框。但是这里无法在更改请求按钮单击时访问每一行。
下面的代码是对话框组件
openDialog(Id, Currency, Amount, Reason, StatusDescription, payment, event) {
let targetAttr = event.target.getBoundingClientRect();
const dialogConfig = new MatDialogConfig();
dialogConfig.disableClose = true;
dialogConfig.autoFocus = true;
dialogConfig.data = {
Id: Id,
Reason: Reason,
StatusDescription: StatusDescription
};
dialogConfig.position = {
top: targetAttr.y + targetAttr.height + 10 + "px",
left: targetAttr.x - targetAttr.width - 20 + "px"
};
dialogConfig.panelClass = ['my-panel','arrow-top'];
const dialogRef = this.dialog.open(EditingDialogComponent, dialogConfig);
dialogRef.afterClosed().subscribe(
data => {
console.log("Dialog output:", data)
}
);
}
下面的代码来自 style.scss
/* Add application styles & imports to this file! */
@import "~@angular/material/prebuilt-themes/indigo-pink.css";
.my-panel {
overflow: hidden !important;
border-radius: 5px !important;
padding: 0px !important;
color: #fff;
}
.my-panel.arrow-top {
margin-top: 40px;
}
.my-panel.arrow-top:after {
content: " ";
position: absolute;
right: 100px;
top: 365px;
border-top: none;
border-right: 15px solid transparent;
border-left: 15px solid transparent;
border-bottom: 15px solid gray;
}
