All, I have an Angular2 application. In this application I have a button that opens a dialog. In this dialog is a single div which I need to act on. Is there any way to execute code in a callback after the dialog and all it's children have been created?
The closest I've got is
<modal #openDialog (focusin)="openExplorer('someData')">
...
</modal>
If I go with that approach then my code get's rexecuted if a user clicks on the form fields inside of this div.
// HTML
<p (click)="openTheDialog(openDialog, 'thisDivRightHere')">Click here to open me, fool</p>
<modal #openDialog (focusin)="openExplorer('someData')">
<div id="thisDivRightHere"></div>
</modal>
// Component
openTheDialog(dlg, someDiv) void: {
this.fooBarService.preformTheAction(someDiv);
}
// Service
preformTheAction = function(someDiv) {
$('#' + someDiv).html(new Date());
}
In the above example, without (focusin) then I can't get a handle on "thisDivRightHere"
But if I use (focusin) I can but the date changes every time somethings interacted with.
I solved it by using setTimeout to wait for the element and a carefully placed callback
// HTML
<p (click)="openTheDialog(openDialog)">Click here to open me, fool</p>
<modal #openDialog (onOpen)="openIt(openDialog, 'thisDivRightHere')" >
<div id="thisDivRightHere"></div>
</modal>
tester(someDiv, dialog, callback): void {
var checkExist = setInterval(function() {
if ($('#'+someDiv).length) {
console.log("Exists!");
clearInterval(checkExist);
callback(dialog);
}
}, 100); // check every 100ms
}
// Component
openTheDialog(dlg) {
dlg.open();
}
openIt(dlg, someDiv) void: {
this.tester(someDiv, this.myService, function(dlg) {
dialog.preformTheAction(someDiv);
});
}
// Service
preformTheAction = function(someDiv) {
$('#' + someDiv).html(new Date());
}
