I have two JSON arrays from an external that I want to loop in Angular, but I am unsure how to do it.
The first array in the object looks like ViewAttributes.FunctionNames and the second array is ViewAttributes.FunctionActive.
Right now I am using a right menu but my objective is to show the correct FunctionNames value in the menu options when the boolean position for each value is true, not false . What do I need to change?
my code is below for example:
view.component.html
<mat-menu #contextMenu="matMenu" #contextMenu2="matMenu">
<ng-template matMenuContent let-action="action">
<button mat-menu-item (click)="onContextMenuAction(action)">{{FunctionNames}}</button>
</ng-template>
</mat-menu>
view.component.ts
// Right Click Context Menu for View Data Table
onContextMenu(event: MouseEvent, action: ViewDataSource) {
event.preventDefault();
this.contextMenuPosition.x = event.clientX + 'px';
this.contextMenuPosition.y = event.clientY + 'px';
this.contextMenu.menuData = { action: action };
this.contextMenu.menu.focusFirstItem('mouse');
this.contextMenu.openMenu();
console.log(this.FunctionNames);
}
onContextMenuAction(action: ViewDataSource ) {
console.log(action);
console.log(parseInt(action[0]));
console.log(parseInt(action[3]));
// this.launchService.launchAction(this.line.targetActionTag.value, this.line.targetActionType);
// tslint:disable-next-line: radix
this.launchService.launchAction(parseInt(action[0]), parseInt(action[3]));
// debugger;
}
and my two JSON array object looks like:
ViewAttributes.FunctionNames = [Value1, Value2, Value3, ....]
ViewAttributes.FunctionActive = [true,false,true, ...]
If you want to show the FunctionNames
based on the boolean value at the corresponding index in FunctionActive
array.Then below code might help you
ViewAttributes.FunctionNames =ViewAttributes.FunctionNames.filter((each,index)=>{return ViewAttributes.FunctionActive [index]})
This will filter the array based on the boolean value in FunctionActive
array.
